CONCLUSION ........................................................ 436
A tragedy looms for trade dress. Encouraged by bad case law and tempted by new technologies, trade dress law threatens to assume a role properly reserved for other forms of intellectual property. Trade dress should aim primarily at protecting the public from confusing the features that identify goods and services. Current trends, however, risk expanding trade dress until it constitutes the very commodities  that it once merely identified. Superficially genuine but fundamentally artificial, this is virtual trade dress. 
Virtual trade dress stakes out rights more enduring, and in many respects more broad, than either copyright or patent would provide. Though already evident in case law, virtual trade dress poses a particular threat of overrunning its ideal habitat: virtual reality.  Despite its potential impact, virtual trade dress has largely escaped the notice of commentators and courts.  Commentary on trade dress law, flowing down two separate channels, has left unexplored the issues raised by [p. 386] virtual trade dress. On the one hand, a good many articles have discussed trade dress protection of computer interfaces.  These articles regard trade dress as merely another tool, of greater or lesser utility, for protecting the "look and feel" of computer software. On the other hand, a smaller number of articles have noted the encroachment of trade dress on territory properly reserved for other forms of intellectual property.  These articles, however, fail to recognize that virtual trade dress poses a disproportionate threat to digital services. [p. 387]
Virtual trade dress has slipped past courts most frequently when embodied in goods mistakenly protected as trade dress.  Courts have also unwittingly granted virtual trade dress rights to servicesrestaurants in particular.  Only rather recently have courts begun to recognize the hazards of trade dress that, however traditional it appears, radically upsets intellectual property's time-tested order. 
Cases establishing virtual trade dress rights in services, though facially less egregious than those establishing similar rights in goods, set an especially troubling precedent. Virtual trade dress in goods cannot expand too far before it clearly transgresses copyright and patent law. These sorts of intellectual property have relatively little sway over services, however, leaving virtual trade dress free to take over the field. Being primarily interactive and service-based, rather than fixed and concrete, virtual environments will prove especially vulnerable to virtual trade dress.
Advocates of virtual reality predict that it will provide computer simulations that effectively duplicate our perceptions of the real world.  Better yet, virtual reality will provide convincing experiences not available in real space, such as walking through fifteenth-century Rome or viewing cellular machinery from the inside out. At present, virtual reality offers more promise than profit.  Trends indicate, [p. 388] however, that virtual reality will eventually support a wide array of entertainment, information, and communication services. 
Nothing this good comes cheaply. To build convincing and effective virtual realities will consume much time, effort, and money. Those who develop virtual realities will want protection against copying that aims at skimming the cream off of their creative efforts. These developersor, rather, their attorneyswill undoubtedly seek protection through all possible means. Given current case law, they will find trade dress protection all too useful.
Why consider now the impact of trade dress law on a technology still far from everyday use? As so often happens with new technologies, we may find ourselves deep into virtual reality sooner than we expect. We will then probably regret not having addressed the legal issues earlier, at our leisure. More important, virtual reality provides an imaginary laboratory for examining current law. As an environment constituted solely of information, virtual reality submits intellectual property law to something akin to "white room" conditions. Thus, well before it comes to fruitionor even regardless of whether it doesvirtual reality can help to detect and amplify existing legal problems. This examination satisfies more than merely theoretical interests. Much of what one concludes about virtual environments will hold true of other artificial environments, such as conventional computer interfaces, restaurants, theme parks, and architectural spaces. In questioning whether trade dress should protect future virtual environments, therefore, this Article provides new grounds for questioning trade dress protection here and now.
By reviewing conventional notions of trademark and trade dress law, Part I of this Article lays the groundwork for the text that follows. Part II gives a brief description of virtual trade dress, contrasting it with real trade dress. Part III discusses how courts have created, and on at least one occasion criticized, virtual trade dress rights in goods and services. Part IV contends that standard justifications for trade dress fit virtual trade dress poorly. Part V sets forth a variety of economic, legal, and policy arguments against creating virtual trade dress rights. Projecting current trends, Part VI explores how virtual trade dress might come to protect virtual environments. This Article con- [p. 389] cludes that not checking virtual trade dress now, while it remains a mere anomaly, would give it license to grow into a very real problem.
Although often treated as a subcategory of trademark law, trade dress in fact represents a unique sort of intellectual property. The Supreme Court has defined trade dress as the "'total image and overall appearance'" of a good,  further specifying that it "'may include features such as size, shape, color or color combinations, texture, graphics, or even particular sales techniques.'"  Trade dress thus encompasses a more diffuse set of intellectual properties than does trademark law. The scope of trade dress protection includes subjects as concrete as decorative tiles and as abstract as restaurant service.  Moreover, trade dress covers various combinations of these concrete and abstract subjects.
Even though courts have not hesitated to apply the Lanham Act  to trade dress, they lack readily apparent authority to do so. The term "trade dress" appears nowhere among the terms defined in section 1127 of the Lanham Act, nor does it appear in any of the Act's other provisions. Yet the Supreme Court recently confirmed that this lacuna will not prevent the Lanham Act from applying to trade dress. 
Did the Court thereby usurp Congress? Hardly. Judicial construction of the Lanham Act has long established its applicability to trade dress,  and Congress appears to have accepted this interpreta- [p. 390] tion.  The broad reach of trademark's common law roots also justifies extending it to trade dress.  Most decisively, trade dress easily fits into the Lanham Act's generous definition of "trade-mark": "any word, name, symbol, or device, or any combination thereof" used to identify goods. 
Whether due to the Lanham Act's inclusive language or the general preeminence of trademark law, most authorities treat trade dress as a proper subset of trademark law. The wiser view, however, recognizes that trade dress and trademark merely overlap. In Vision Sports, Inc. v. Melville Corp.,  the United States Court of Appeals for the Ninth Circuit noted some distinctive features of trade dress:
Trade dress protection is broader in scope than trademark protection, both because it protects aspects of packaging and product design that cannot be registered for trademark protection and because evaluation of trade dress infringement claims requires the court to focus on the plaintiff's entire selling image, rather than the narrower single facet of trademark. Furthermore, trade dress may cover not only a selling image, but a selling method.  [p. 391]
The fact that trade dress may take too vague a form to permit registration deserves emphasis.  The Lanham Act requires an applicant for registration to provide the Patent and Trademark Office (PTO) with a "drawing" of the mark (or, by extension, trade dress) submitted for application.  An applicant would find it impossible to draw the aggregate effect of a restaurant's "decor, menu, layout and style of service," to cite one example of federally protectable trade dress,  nor will such a collection of appearances and actions readily submit to a verbal description. If such vagueness keeps a trade dress claim off the principal register, imagine what it does to parties trying to avoid an unfair competition suit brought under section 43(a) of the Lanham Act.  These parties can neither search federal registrations for similar trade dress, nor benefit from similarly text-bound state and commercial records, nor ascertain with certainty the scope of the trade dress that they happen to locate. 
These differences between trade dress and trademark call for treating them differently. Nevertheless, courts tend to treat trade dress like any other form of intellectual property covered by the Lanham Act.  This failure to account for the unique features of trade dress has helped give rise to the problem at hand: virtual trade dress.
Before examining how courts have created virtual trade dress rights, and the theoretical objections to their having done so, it may prove helpful to highlight the differences between virtual trade dress and real trade dress. Consider the following contrasts: Virtual trade dress arises when a court gives trade dress protection to exactly the same commodity that consumers value. Real trade dress has little intrinsic value. Consumers value virtual trade dress for its own qualities, purely for the aesthetic experience that it provides. Consumers value real trade dress primarily because it reveals the otherwise hidden qualities of a [p. 392] good or service, whereas virtual trade dress points to other qualities only incidentally, if at all.
These contrasts between virtual and real trade dress push their definitions to extremes, of course. The line dividing them blurs a bit in the real world. Just as the existence of dawn and dusk does not prove that night equals day, however, virtual trade dress and real trade dress remain distinct. Far from hiding similarities, theoretically pure definitions help to categorize the fuzzy facts that pervade actual practice.  Fortunately, case law provides both mixed and unalloyed examples of virtual trade dress.
Virtual trade dress has already surfaced in case law. To best illustrate judicial recognition of virtual trade dress rights, the cases analyzed in this PartHartford House, Ltd. v. Hallmark Cards, Inc.,  Romm Art Creations Ltd. v. Simcha International, Inc.,  Fuddruckers, Inc. v. Doc's B.R. Others, Inc.,  and Two Pesos, Inc. v. Taco Cabana, Inc. necessarily present extreme results. Nonetheless, these cases have proven influential, and they help bring to the fore factors implicit in other cases.  Case law contrary to virtual trade dress rights runs a bit thin. Even courts that have denied suspect claims have generally failed to do so for the right reasons.  The recent decision in Duraco Products, Inc. v. Joy Plastic Enterprises, Ltd.  represents a notable exception to this rule.
1. Hartford House, Ltd. v. Hallmark Cards, Inc.Hartford House stands out as the single best example of a court's creating virtual trade [p. 393] dress. Hartford House, together with others, manufactured and distributed greeting cards under the name Blue Mountain Arts (Blue Mountain).  Blue Mountain sued rival Hallmark Cards (Hallmark) for infringing the trade dress of two lines of Blue Mountain's cards"AireBrush Feelings" and "Watercolor Feelings."  The district court found inherently distinctive and highly uniform features in these two card lines, features that combined in an overall appearance consumers could recognize and attribute to Blue Mountain.  The United States Court of Appeals for the Tenth Circuit affirmed.  The list of inherently distinctive and highly uniform features included:
1. A two-fold card containing poetry on the first page and the third page.This collection of features qualifies as virtual trade dress because it constitutes the very good that consumers value. Taking these features away leaves only plain paper.
2. Unprinted surfaces on the inside three panels.
3. A deckle edge on the right-side of the first page.
4. A rough edge stripe of color, or wide stripe, on the outside of the deckle edge of the first page.
5. A high quality, uncoated and textured art paper for the cards.
6. Florescent ink for some of the colors printed on the cards.
7. Lengthy poetry, written in free verse, typically with a personal message.
8. Appearance of hand-lettered calligraphy on the first and third page with the first letter of the words often enlarged.
9. An illustration that wraps around the card and is spread over three pages, including the back of the card.
10. The look of the cards primarily characterized by backgrounds of soft colors done with air brush blends or light watercolor strokes, usually depicting simple contrasting foreground scenes superimposed in the background. 
Although a competitor would not have to forego copying all of these features to avoid infringing Blue Mountain's supposed trade [p. 394] dress, the scope of Blue Mountain's rights remained vague.  At any rate, together or apart, the listed features qualify as virtual trade dress. They constitute the very goods that consumers value; taking them away leaves only plain paper. As this analysis demonstrates, Blue Mountain would earn no profit without selling the features covered by its trade dress claim.
Such virtual trade dress does not fit well within the rubric of real trade dress law. The district court in Hartford House adopted the standard trademark framework for judging trade dress infringement. It required Blue Mountain to show that its trade dress was (1) nonfunctional, (2) distinctive,  and (3) likely to be confused by consumers with the defendant's trade dress.  In each of these steps, however, the court's failure to recognize the virtual trade dress at issue led it astray.
a. Functionality.The district court in Hartford House defined as functional a feature "'essential to the use or purpose of the article or that affects the cost or quality of the article.'"  In the de jure, if not in the de facto sense, the functionality test boils down to asking whether protecting the trade dress in question "'will hinder competition or impinge on the right of others to compete in the sale of goods.'"  The district court found Blue Mountain's card design nonfunctional because competitors had access to alternative designs.  The appellate court affirmed that finding.  More careful consideration, however, reveals that this standard analysis of functionality goes awry when applied to virtual trade dress.
With virtual trade dress, what counts as an "alternative" design depends on the definition of the relevant market. Define the market [p. 395] broadlyas all cardsand the reasoning in Hartford House stands. Define it narrowlyas nonoccasion, emotionally expressive greeting cards characterized by a hand-crafted appearance and free verseand it becomes evident that the Hartford House court protected not simply trade dress, but an entire line of products.
In Hartford House, the record demonstrated that Hallmark copied Blue Mountain's designs only after Hallmark had failed at wholly original attempts to enter the market for the type of cards in question.  The district court interpreted Hallmark's intentional copying as proof that Blue Mountain's trade dress had achieved secondary meaning and, thus, qualified as distinctive.  Because Blue Mountain's trade dress covered the very good that consumers valued, however, Hallmark's copying demonstrated only that Blue Mountain had created a profitable design scheme one that it either could not or would not protect through a design patent or copyright. 
Judges tend to frown on intentional copying.  Yet in its zeal to protect the David-sized Blue Mountain, the Hartford House court actually gave Goliath, Hallmark, new means to monopolize the card market. With its vast resources to generate and test card designs, Hallmark can now seize virtual trade dress rights to the best new goods on the market. Furthermore, Hallmark's relatively vast litigation resources will cow lesser competitors that dare to probe the amorphous boundaries of its claims. Thus, while Hallmark lost the battle in Hartford House, it won the war for broad and perpetual monopolies on its most profitable card designs. [p. 396]
b. Distinctiveness.The district court in Hartford House also employed a definition of functionality that relied on distinctiveness: "A non-functional feature is one whose primary value is to identify the source of the particular goods or services."  On this measure, Blue Mountain's putative trade dress fails miserably. Blue Mountain almost certainly did not design its cards primarily to identify their source; its trademark on the back of the cards served that function. Presumably, Blue Mountain designed its cards primarily to satisfy consumer demand.
In evaluating whether Blue Mountain's trade dress qualified as distinctive, and thus protectable, the district court correctly observed that "'[t]rademark strength is measured by its tendency to identify the goods sold under the mark as emanating from a particular source, although possibly [an] anonymous source.'"  This test works poorly, however, on trade dress that constitutes exactly what consumers value. 
Courts ought not use trade dress law to grant perpetual copyrights.  Yet a widely marketed copyright could give rise to exactly the same sort of association with a particular source that the Hartford House court cited as proof of distinctiveness.  By failing to first ask whether Blue Mountain's putative trade dress constituted virtual trade dress, the court turned a distinctive good into a protected good.  Of course, if courts persist in protecting the types of design that consumers value, consumers will eventually learn to associate a particular style [p. 397] with a particular source. That merely demonstrates the risk of a vicious cycle of monopolization; it does not justify leaping into it. 
The district court also erred in citing Hallmark's intentional copying as proof that Blue Mountain's trade dress had achieved secondary meaning.  Hallmark did not copy Blue Mountain's design so that it could pass off Hallmark cards as Blue Mountain cards. Hallmark's cards retained their trademarks. Furthermore, Hallmark did not copy the card designs to free ride off of Blue Mountain's goodwill. Blue Mountain had no goodwill to steal. Because, through inspection, a customer can perceive all of a card's qualities immediately, there is no residual hidden value that a trademark or trade dress could help to disclose.  What you see is what you get.  Hallmark copied Blue Mountain's cards solely to compete in offering consumers a particular type of commodity, demonstrating that when it comes to virtual trade dress, courts should not assume that intent to copy indicates secondary meaning. 
c. Confusion.The Hartford House courts, both higher and lower, noted that consumers could not distinguish the two competing card lines by reference to their stylistic features.  That observation, however, proves nothing about the validity of a trade dress claim, because the courts erred in judging the stylistic features as being nonfunctional and distinctive. Consumers generally cannot distinguish products protected by the same copyright or design patent, either. [p. 398]
d. Breadth of the Virtual Trade Dress Protected.Lastly, the district court in Hartford House gave Blue Mountain a potentially immortal right to a particular style of visual (not just card) design. Trade dress claims can jump across product lines. The district court noted, for example, that a ceramics manufacturer had purchased "a license to replicate the Blue Mountain look on mugs and other ceramic products." 
As this parade of horribles indicates, Hartford House represents an egregious example of how virtual trade dress can violate established categories of intellectual property and wreak havoc on traditional legal doctrines. Romm Art Creations Ltd. v. Simcha International, Inc.,  however, follows close behind.
2. Romm Art Creations Ltd. v. Simcha International, Inc.In Romm Art, as in Hartford House, a court created rights to virtual trade dress by giving trade dress protection to the actual products that consumers valued. Plaintiff Romm Art held a license to sell limited editions and posters copied from works in the "Women and Cafes" collection of Israeli artist Itzchak Tarkay.  Defendant Simcha distributed limited editions and posters of the work of artist Patricia Govenzensky, which supposedly resembled Tarkay's work in terms of patterns of color and shading, placement of figures, physical attributes and clothing of women portrayed, and depiction of women sitting and reclining.  Romm Art accused defendant Simcha of distributing art "'slavishly similar and entirely derivative of'" Tarkay's work, and brought suit for trade dress infringement. 
Simcha raised no objection to the magistrate's finding that the Lanham Act provides relief for infringing the trade dress of commercial reproductions of particular art works.  This proved fatal to the defense.  Relying heavily on Hartford House, the Romm Art court found the trade dress nonfunctional  and likewise upheld the magistrate's finding of secondary meaning  and likelihood of confusion.  [p. 399]
In Romm Art, as in Hartford House, the court cited absolutely no feature of the artwork that consumers would value other than those constituting the supposed trade dress.  Intent on applying trade dress law, the Romm Art court downplayed the real purpose of the artwork, stating: "Other than aesthetic gratification, these images serve no other purpose than to identify their source/creator."  Of course, this claim also holds true of the paintings of Van Gogh. Other than representing some of Western civilization's most compelling artworks, Van Gogh's paintings do no more than identify the source of a particular consumer good.
Perhaps the Romm Art court's emphasis on identification would have made sense if the works in question had been unique collector items, valuable regardless of their aesthetic value. As poster reproductions of the originals, however, these works held no special cachet. The court could have bolstered its reasoning with a showing that the works lacked labels clear enough to counteract any confusion caused by their similar styles. Although the court observed that "[t]he general public's confusion is only increased when the name of the artist is eliminated or covered up in the matting and/or cropping process,"  it cited no evidence that this did or would actually occur.
Furthermore, that the products in question had no value besides their virtual trade dress arguably makes attribution of source or origin irrelevant. The prints, like the cards at issue in Hartford House, represented inspection goods. Failing to identify their source would not have left any residual quality hidden.  Consumers got exactly what they perceived, label or not. Here again, virtual trade dress contravened the established taxonomy of intellectual property by providing rights of indefinite duration to a particular style of design.  [p. 400]
The two trade dress cases that apply most directly to virtual environmentsFuddruckers, Inc. v. Doc's B.R. Others, Inc.  and Two Pesos, Inc. v. Taco Cabana, Inc. involve claims to the design and decor of restaurants. The reason for this seemingly odd coincidence becomes clear on reflection: restaurants sell not just food but dining experiences. They aim to offer their customers artificial environments having both entertaining and useful features. Those that develop virtual realities will no doubt aim at similar goals.
Virtual reality developers will also share with restaurant owners the desire to wield intellectual property laws to foreclose effective competition. Everybody, it seems, wants a monopoly. Not everyone deserves one, though. Fuddruckers and Two Pesos create undeservedly broad intellectual property rights. The plaintiffs in each of these cases won virtual trade dress rights to their restaurant services, though in contrast to Hartford House and Romm Art, this virtual trade dress came mixed with the real thing. Had the Fuddruckers and Two Pesos courts recognized the risks of granting virtual trade dress rights, they might have tailored their remedies accordingly.
1. Fuddruckers, Inc. v. Doc's B.R. Others, Inc.The plaintiff in Fuddruckers alleged infringement of trade dress it had established in its restaurants' decor and services.  The claimed decor included large condiment and appetizer bars, two-by-four white tiles, neon signs, mirrors, and director's chairs.  The claimed services included making food preparation and storage readily visible, offering a free restaurant newspaper, and selling bones to customers for their dogs.  Denied a franchise, the defendants borrowed these and other elements of the alleged trade dress for their rival restaurant, Doc's B.R. Others.  Fuddruckers sued for trade dress infringement, lost at trial, and appealed.  The appellate court approached the problem largely as it would have approached a trademark infringement claim, holding that "trade dress may be protected if it is nonfunctional and has acquired secondary meaning and if its imitation creates a likelihood of con- [p. 401] sumer confusion."  Yet the Fuddruckers court could not ignore certain quirks unique to the case.
First, the nature of Fuddruckers's claim ensured that its trade dress would include many unquestionably functional elements, such as counters, cups, and lights.  The court thus took pains to stress that "functional elements that are separately unprotectable can be protected together as part of a trade dress."  Like the court in Hartford House, the Fuddruckers court asked whether the elements created a distinctive impression when taken together as a whole  and agreed that a combination of elements can qualify for trade dress protection even if the individual elements cannot. 
The court in Fuddruckers also faced the question of whether one who makes a trade dress claim can, like one making a trademark claim, escape the burden of showing secondary meaning by establishing that the intellectual property in question has inherently distinctive qualities.  The court complained that Fuddruckers "has not offered this court a definition of what 'inherently distinctive' in the trademark sense might mean in the absence of secondary meaning."  Perhaps to its relief, the Fuddruckers court found that it did not need to decide whether trade dress could ever be inherently distinctive per se.  Final resolution of that question would have to wait for Two Pesos.
The Fuddruckers court overlooked the real oddity in the plaintiff's trade dress claim: the claim included the very commodity that the restaurant offered and sold to consumers.  As Professor Gifford has explained, the trade dress in Fuddruckers represents "not packaging, but rather a constituent part of that which is being purchased. Restaurant customers buy more than the food; they buy ambience and at- [p. 402] mosphere. It is the latter over which Fuddruckers sought protection." 
2. Two Pesos, Inc. v. Taco Cabana, Inc.As in Fuddruckers, Two Pesos involved two restaurants wrestling over the rights to shared trade dress. The plaintiff, Taco Cabana, claimed that the defendant, Two Pesos, had copied its building's exterior, sign, kitchen floor plan, decor, menu, serving equipment, uniforms, and other features reflecting the restaurant's Mexican theme.  Like the court in Fuddruckers, the Two Pesos Court overlooked the particular problems raised by the virtual trade dress at issue.
Unlike the court in Fuddruckers, the Court in Two Pesos addressed whether the same tests for determining a trademark's inherent distinctiveness and secondary meaning also apply to trade dress.  The Court held: "There is no persuasive reason to apply to trade dress a general requirement of secondary meaning which is at odds with the principles generally applicable to infringement suits under § 43(a) [of the Lanham Act]."  In broad terms, the Court found that section 43(a) "provides no basis for distinguishing between trademark and trade dress."  For better or worse, Two Pesos signaled that the Supreme Court will probably treat trade dress as it does any other form of intellectual property covered by the Lanham Act.
The Supreme Court in Two Pesos neglected, however, to prepare courts for this brave new world of federal trade dress law. It provided no standard for detecting inherent distinctiveness in trade dress,  nor did it criticize the trial court's clearly erroneous finding that the plaintiff's trade dress qualified as distinctive.  As a later court noted of the trade dress protected by Two Pesos, "the product itself is the room and its furnishings as well as whatever food is served."  Such trade dress should not slip past the test for inherent distinctiveness, because [p. 403] trade dress that constitutes part of a commodity cannot fail to describe it. 
Duraco Products, Inc. v. Joy Plastic Enterprises, Ltd.  represents the most thoroughly reasoned, and almost the only, case in which a court has refused to grant trade dress protection on the grounds that it represents the very commodity that consumers value.  The plaintiff in Duraco manufactured and sold plastic planters resembling Grecian stone urns.  Plaintiff brought suit under section 43(a) of the Lanham Act  against parties that made and marketed planters of similar shape, appearance, and texture.  The United States Court of Appeals for the Third Circuit affirmed, on different grounds, the trial court's refusal to grant the plaintiff a preliminary injunction. 
The Third Circuit's reasoning followed a number of interesting and insightful steps. The court launched its discussion with a distinction that would, however, prove controversial. The court claimed that the case concerned "trade dress said to inhere in the product itself, rather than trade dress alleged in a product's packaging."  It termed the former type of trade dress "product configuration," the latter type "product packaging," and explained that "the legal doctrines in these two very different situations will substantially diverge." 
This distinction allowed the court to avoid the reach of Two Pesos, a case in which the Duraco court found no guidance on how to treat product configuration.  The court in Stuart Hall Co. v. Ampad Corp.  criticized this maneuver, observing that "[w]e, however, read Two Pesos as resting on a presumption that 'trade dress' is a single [p. 404] concept that encompasses both product configuration and packaging."  This criticism gives too little credit to the finesse with which the Duraco court sidestepped Two Pesos.  The Duraco court in fact argued that Two Pesos did not decide whether trade dressparticularly trade dress in a product configurationcan ever actually qualify as inherently distinctive.  Rather, "for purposes of that case, the Court assumed that the restaurant decor at issue was . . . inherently distinctive."  Justified or not, the distinction made by the Third Circuit in Duraco freed it to approach the problem of virtual trade dress from a new, and ultimately better, angle.
The Duraco court next criticized the plaintiff's routine application of the generic-descriptive-suggestive-arbitrary-or-fanciful scale of ascending distinctiveness first set forth in Abercrombie & Fitch Co. v. Hunting World, Inc.,  and afterward applied indiscriminately to trademark and trade dress cases alike.  The Third Circuit's exceptional statement of the issue bears quoting at length:
[W]e do not think it helpful or proper to transplant the categorical distinctiveness inquiry developed for trademarks to product configurations, where the alleged trade dress lies in the very product itself. . . . [A] product configuration differs fundamentally from a product's trademark, insofar as it is not a symbol according to which one can relate the signifier (the trademark, or perhaps the packaging) to the signified (the product). Being constitutive of the product itself and thus having no such dialectical relationship to the product, the product's configuration cannot be said to be "suggestive" or "descriptive" of the product, or "arbitrary" or "fanciful" in relation to it. The very basis for the trademark taxonomythe descriptive relationship between the mark and the product, along with the degree to which the mark describes the productis unsuited for application to the product itself. 
The Duraco court continued with the observation that trade dress qua product befuddles attempts to discern whether consumers buy a product because of the goodwill associated with its trade dress or sim- [p. 405] ply because they like its trade dress.  Courts should thus not assume that a unique product configuration, which they might mistakenly regard as "distinctive" in the trademark sense, necessarily identifies the product's source. To make that mistake may well result in a world in which, thanks to courts having created virtual trade dress rights, consumers assume that a product's features identify the product's source. That merely signifies the circularity of the problem. As the Duraco court explained: "[A]ny perceptible product feature or combination or arrangement of features can distinguish goods, and perhaps is likely to do so if, as a rule, nobody else were allowed to copy it."  Such an unseemly result would by no means excuse creating trade dress rights in product configurations.
Despite its skepticism about trade dress claims to product configurations, the Duraco court did not rule them out entirely. Indeed, it read Two Pesos to require recognition of some such claims.  The Third Circuit conditioned its acceptance, however, on the following test: "[T]o be inherently distinctive, a product configuration . . . for which Lanham Act protection is sought must be (i) unusual and memorable; (ii) conceptually separable from the product; and (iii) likely to serve primarily as a designator of origin of the product."  In applying this test to the product configuration before it, the court noted that neither the product's success nor the defendant's intentional copying established secondary meaning;  rather, both could have resulted merely from the intrinsic value of the trade dress in question. 
As this review indicates, Duraco provides a probing and far-reaching examination of the problems presented by trade dress that itself constitutes what consumers value. The opinion offers promising solutions to those problems. There are two limitations on the court's otherwise comprehensive treatment, however. First, Duraco expressly declined to address the difficult question of how to evaluate the functionality of trade dress that itself constitutes a consumer's desideratum.  Not having the court's freedom to resolve the virtual trade dress problem on other grounds, this Article will address the problem of functionality below.  [p. 406]
Second, although Duraco concerned trade dress having per se value, that trade dress mingled with a product having independent value.  Had the court metaphorically peeled the trade dress off the urns in question, a product having some residual valuean ordinary plastic planter, for examplewould have remained. The trade dress in Hartford House, Romm Art, and more pointedly in hypothetical cases from virtual environments, examined below, differs in a crucial regard: it comes unattached to any independently valuable product. Peeling away such purely virtual trade dress leaves behind absolutely nothing of value. This consideration renders much of the Duraco court's test of inherent distinctiveness irrelevant, as pure virtual trade dress should never merit protection as an indicator of source.
The justifications for protecting trade dress, as distinct from trademark, have not received much scholarly attention. Arguments in defense of trademarks fit trade dress quite well, and would have done so even if Two Pesos had not essentially equated the two areas of law.  Trade dress and trademarks share common roots and serve common ends. Section A argues that trademark law has as its fundamental goal revealing otherwise hidden information about the quality of goods and services. Section B explains why free riders threaten this informative function and how granting property rights to marks that identify commodities inhibits free riding. Section C concludes that these same arguments hold true in virtual environments.
To put the matter in fundamental terms, trademark law aims at providing information about the otherwise hidden qualities of particular goods or services.  Economists classify goods with hidden qualities as "experience" goods or "credence" goods.  Experience goods [p. 407] (and, by extension, services) possess qualities that consumers can detect only after purchase. Examples of experience commodities include boxed products, medicine, and new employees. Credence goods and services, in contrast, possess qualities that might never become apparent. Consumers purchase these based on authoritative advice. Examples of credence commodities include vitamins, legal advice, and a good education. 
At least with regard to experience commodities, protectable marks and trade dress help consumers to perceive immediately qualities that would otherwise remain hidden until after purchase.  Trademarks reduce consumers' search costs by making it easier for them to identify goods.  This, in turn, encourages producers that hold trademarks to invest in the quality of their products because they can develop valuable goodwill by maintaining consistent quality over time and across consumers.  Both of these effectsreducing consumers' search costs and encouraging producers' consistencystem from the fundamental purpose of trademark law: to reveal information about the hidden qualities of goods and services.  [p. 408]
Trademarks thus add no value to goods that have no hidden qualities.  Consumers can perceive the qualities of such "inspection goods" immediately, before paying anything more to consume them.  Examples of inspection goods include nonoccasion greeting cards, paintings, and screen savers. A similar analysis applies to inspection services; a simple street performance, for example, wears its value on its face. Certain contexts can, of course, obscure the otherwise apparent value of inspection commodities. A retailer ordering cards in bulk may thus benefit from reference to the "Blue Mountain" mark. Consumers browsing through a card rack, however, will find the same mark useless.  They need only inspect a card to determine its worth.
This same analysis applies to trade dress. In its usual, proper role, trade dress informs consumers about the hidden qualities of goods and services. Trade dress runs the peculiar risk, however, of constituting the very commodity that consumers value and, thus, becoming virtual trade dress. Virtual trade dress can do nothing to inform consumers of its own hidden qualities. The proof of its value, like that of the proverbial pudding, is in its consumption. Virtual trade dress thus cannot serve the primary goal of trademark law: to inform consumers about the hidden qualities of goods and services.  [p. 409]
Competitors have a powerful incentive to copy the trademarks that identify successful goods and services. Landes and Posner explain that "[t]he free-riding competitor will, at little cost, capture some of the profits associated with a strong trademark because some consumers will assume (at least in the short run) that the free rider's and the original trademark holder's brands are identical."  A tragedy of the commons thus threatens trademark law. If not prevented, free riding will corrupt the information about hidden qualities that trademarks send to consumers. Unable to trust trademarks, consumers will ignore them. With no way to convince consumers about the hidden quality of their commodities, producers will let that quality fall.
As with other problems arising out of common ownership, assigning property rights to the contested resource provides a workable solution. In this commons problem, trademarks represent the contested resource, and property rights thereto provide their holders with the power to bar other parties from using the marks in manners likely to confuse consumers. This property right could theoretically vest in consumers themselves, who would bring class action misrepresentation claims against infringing parties.  Such a scheme would give rise to large administrative costs, however.  In practice, therefore, trademark rights vest in those who create the products to which the trademarks attach.
Free riding would pose no risk to intellectual property rights if the inherent costs of copying always outran the benefits. In the real world, however, copying intellectual property almost always costs relatively less than creating it from scratch.  This holds as true for trademarks and trade dress as it does for copyrights and patents. In each case, therefore, the law tries to make up the difference by imposing additional costs for unauthorized copying.  [p. 410]
As in real space, it will usually prove cheaper to copy a computer interface or virtual environment than to produce a competing one from scratch. Copying a marketable setting, be it real or virtual, always avoids the costs of creative design. If accomplished by duplicating the relevant software, copying a virtual setting would in addition avoid "construction" costs. Technical devices such as encryption, and legal doctrines such as copyright, patent, or trade secret law, would presumably protect the software itself from duplication. Copyright lawand to some extent trade dress lawwould protect the output of that software. These considerations merely go to show that nothing about computerization automatically cures the problems that have always plagued intellectual property. To the contrary, valid trade dress continues to require legal protection, while virtual trade dress continues to require legal censure.
Virtual trade dress does not fare well under a cost/benefit analysis. Rather than adding value to an associated commodity, it is the very good or service that consumers desire. It thus does little or nothing to lower the cost of identifying a commodity's source or affiliation. On the other hand, protecting virtual trade dress has a considerable downside cost.
As an immediately perceptible desideratum, virtual trade dress represents an inspection commodity. Lacking residual hidden value, such a good or service gains little from affiliation with a trademark or trade dress. Consumers can identify the qualities of an inspection commodity without further purchase and can thus choose whether to consume it without the help of marks indicating hidden qualities.  To the extent, if any, that virtual trade dress identifies a product's source, it does so needlessly.
Granting rights to virtual trade dress threatens to create, in effect, a new intellectual property regime protecting product designs as well as the design of services. Those who have called for legislative protection of product design argue that it would efficiently reward innovation.  That Congress has consistently refused such entreaties says at [p. 411] least something about the merits of those arguments.  Beyond the concern that courts have evaded congressional intent by creating rights to virtual trade dress, it seems unlikely that virtual trade dress would protect product design efficiently. The potentially limitless life span of virtual trade dress strikes a poor balanceor, rather, no balancebetween encouraging innovation in product designs and opening them to public access. 
Even apart from the legal and policy arguments against creating rights to virtual trade dress, defending rights to virtual trade dress would give rise to large transaction costs. Claimants typically find it difficult to capture their diffuse trade dress in a description sufficiently concrete to qualify for registration.  Thanks to the broad reach of section 43(a), however, claimants find registration largely unnecessary.  Not being registerable or registered, virtual trade dress usually will remain hidden from parties that search the prior art in an effort to avoid liability for infringement. Those parties will no doubt rue the fact that section 43(a) does not excuse innocent infringement. 
Because virtual trade dress has such vague boundaries, the exact scope of claims to it will resist definition. This will make it hard to assign value to infringement claims and, thus, to settle litigation.  The diffuse nature of virtual trade dress and the difficulty in resolving infringement claims will more than deter parties that consider adopting new trade dress. Far from encouraging innovation in product design, virtual trade dress thus threatens to have a net effect of stifling it. [p. 412]
1. Distinctiveness.Courts traditionally classify marks and trade dress on the Abercrombie scale of distinctiveness, which ascends through generic, descriptive, suggestive, arbitrary, or fanciful levels of distinctiveness.  To win legal protection from copying, a mark or trade dress must either possess inherent distinctiveness (by qualifying as suggestive, arbitrary, or fanciful) or acquire it through secondary meaning (by showing long and effective use of the descriptive element).  As the Duraco court noted, this taxonomy fits product configurations awkwardly.  Nonetheless, inquiry into the fundamentals of the Abercrombie scale shows that it disqualifies virtual trade dress as inherently nondistinctive. As the very product that consumers value, virtual trade dress cannot help but remain indistinct from that product. 
At root, the Abercrombie scale measures the metaphorical distance between the "sense" of a mark or trade dress and its "reference." The sense of a symbol lies somewhere between the wholly subjective impressions that it arouses in each observer and the objective, external thing to which it refers.  Thus, "morning star" has a different sense from "evening star" even though both names refer to the same object: Venus.  This abstract notion casts new light on the Abercrombie scale.
A fanciful mark, like KODAK, makes no sense as a word standing alone.  It functions solely to refer to KODAK goods and services. This demonstrates that with fanciful marks the distance between sense [p. 413] and reference reaches from nothing at all to something concretea maximum level of distinctiveness. An arbitrary mark like NOVA, in contrast, has some sense (a stellar explosion) independent of its referent (a particular television program).  NOVA still does not refer to a competing commodity, however. With regard to arbitrary marks, sense and reference approach each other but stay far enough apart to make such marks inherently distinctive.
Sense and reference draw still nearer in a suggestive mark, such as HABITAT, because it has a sense (living space) that hints at its referent commodity (home furnishings).  A descriptive mark like COCO-QUININE paints its referent (a combination of chocolate and quinine) in bald terms, bringing sense and reference quite close together.  A generic word, such as CEREAL, can never win trademark protection because its sense (cereal) comes as close to its referent (cereal) as a word can get to a thing.
Virtual trade dress carries this trend to its logical extreme, merging sense and reference completely. As the very product that consumers value, virtual trade dress signifies itself. To the extent that it has any sense as a signal of value, it points only at the value found within its own scope. The court in Duraco thus erred when, in grudgingly trying to fit virtual trade dress on the Abercrombie scale, it said that "one could at best say that a product configuration is descriptive of (because identical with) the product itself."  As the above analysis demonstrates, trade dress constituting a product does not describe the product, nor does it qualify as generic of the product; rather, it merges sense and reference to become the product.
2. Functionality.Judicial interpretation of the Lanham Act has established conclusively that the Act grants no protection to "functional" goods or services,  even though the Act itself nowhere defines the term. Courts have interpreted the term "functional" in a [p. 414] variety of ways.  The same court will sometimes even advance several definitions together with the admonition that none applies in a mechanical fashion.  Virtual trade dress violates any of these various tests of functionality, however, as well as the fundamental policy that unifies them.
The Supreme Court recently explained that a mark or trade dress will qualify as functional "'if it is essential to the use or purpose of the article or if it affects the cost or quality of the article,' that is, if exclusive use of the feature would put competitors at a significant nonreputation-related disadvantage."  This definition of functional was previously applied at trial,  and affirmed on appeal,  in Hartford House. The test's general use thus invites the same analysis that applied above to its particular use in Hartford House. 
To apply this test of functionality properly, however, a court must define the relevant market narrowly. In the case of virtual trade dress, the court must recognize that trade dress itself constitutes the product at issue, the desideratum of the relevant market.  As such, the trade dress "'is essential to the use or purpose of the article'" and its exclusive use "would put competitors at a significant nonreputation-related disadvantage."  Therefore, virtual trade dress qualifies as functional.
Despite quoting this particular test, the Court in Qualitex Co. v. Jacobson Products Co.  did not rule out using other tests of functionality.  It implicitly endorsed the "primary value" test.  The court in [p. 415] Hartford House misapplied this test, but recited it correctly: "A non-functional feature is one whose primary value is to identify the source of the particular goods or services."  Although the Supreme Court in Qualitex did not explicitly adopt this test, it approved registration of the mark in questiona green-gold colorwith the observation that it "serves no other function" than to identify its source.  The Qualitex Court further observed that, in general, color "can act as a symbol that distinguishes a firm's goods and identifies their source, without serving any other significant function."  This test of functionality plainly bars virtual trade dress, which primarily serves not to identify source, but rather to embody the very commodity that consumers value.
A more powerful version of the "primary purpose" test appears especially well suited to detecting virtual trade dress. This test, popular in the Third Circuit, frames the issue in negative terms: "'Proof of nonfunctionality generally requires a showing that the element of the product serves no purpose other than identification.'"  This test works, however, only if the party claiming rights to a mark or trade dress bears the burden of proving it nonfunctional. It will thus not apply universally, as circuits have split on the question of who bears the burden of proving functionality.  Moreover, the Third Circuit, which [p. 416] has been distinguished for applying so narrow a test,  has not employed it to the exclusion of less restrictive tests. 
Despite their various formulations, all functionality tests aim at the same fundamental policy goal: balancing monopoly rights against public access. As the Supreme Court explained in Qualitex: "The functionality doctrine prevents trademark law, which seeks to promote competition by protecting a firm's reputation, from instead inhibiting legitimate competition by allowing a producer to control a useful product feature."  Typical of such discussions, however, the Court went on to express concern solely about the impact of functional marks on patent law, ignoring the conflict with copyright: "It is the province of patent law, not trademark law, to encourage invention . . . . If a product's functional features could be used as trademarks, however, a monopoly over such features could be obtained without regard to whether they qualify as patents and could be extended forever . . . ." 
However well intentioned the Court's concern, it appears, on reflection, strangely parsimonious. Utility patents no doubt aim to en- [p. 417] courage innovation by granting limited monopolies in functional inventions. Does not copyright law also aim to encourage creativity? Congress has power to legislate in each area under the grace of the same constitutional provision: Article I, Section 8, Clause 8.  This provision specifies that both patents and copyrights shall persist "for limited Times."  Surely, no one doubts that both utility patents and copyrights constitute valuable monopolies and that competitors without such monopolies suffer considerable disadvantages. It seems reasonable to conclude that if courts bar trade dress claims that would interfere with Congress's carefully balanced scheme of utility patent rights, they ought likewise to bar trade dress claims that interfere with copyright law.  The same holds true of trade dress claims that interfere with the law of design patents because it, no less than the law of utility patents and copyright law, derives from the Constitution's Intellectual Property Clause. 
This plea for equal treatment will not get far if it turns out that trade dress simply cannot interfere with copyrights and design patents in the way that it interferes with utility patents. The next section will show that it can. For the present purpose of measuring virtual trade dress against the fundamental test of functionality, it suffices to observe that virtual trade dress allows one competitor among many to seize a potentially eternal monopoly on subject matter more properly covered by the Intellectual Property Clause.
Suppose, for example, that a court gave one publisher an immortal copyright, or one manufacturer an immortal design patent, while limiting competitors to conventional limited rights. Would we not say, in each case, that the court was "inhibiting legitimate competition"?  Virtual trade dress has a similar effect. With regard to goods and services that resemble real trade dress enough to fall under its aegis, virtual trade dress offers a potentially eternal right to market the very commodity that consumers value. It thus upsets the balance that legislators have struck between encouraging innovation and freeing access to ideas. In sum, virtual trade dress violates the policy at the heart of the functionality doctrine. [p. 418]
Virtual trade dress threatens the coherency of federal intellectual property policy because it transgresses the established boundaries and usurps the traditional roles of trademark, copyright, and patent law. Such an impact certainly renders virtual trade dress unwelcome. It may, furthermore, render it unconstitutional. This provides yet another reason, in addition to those arising out of its violation of trademark law proper,  for questioning the propriety of virtual trade dress.
Though they contain damning dicta, the familiar Sears, Roebuck & Co. v. Stiffel Co.,  Compco Corp. v. Day-Brite Lighting, Inc.,  and Bonito Boats, Inc. v. Thunder Craft Boats, Inc.  line of cases does not directly address the constitutionality of trade dress qua desideratum. Those cases relied on the Constitution's Supremacy Clause  to overturn state laws that interfered with federal intellectual property policy.  Virtual trade dress, in contrast, risks unconstitutionality on far less familiar grounds: its grant of potentially eternal rights in intrinsically valuable intellectual property may violate the limits set forth in the Constitution's Intellectual Property Clause.  These constitutional questions will remain moot, however, if virtual trade dress does not grant rights that conflict with those offered by the copyrights or design patents. Whether it does so poses a nice question, addressed forthwith.
1. Virtual Trade Dress vs. Copyright Law.Consider first the potential conflict between virtual trade dress and copyrights. Federal law bars the unauthorized duplication of trade dress only if it confuses consumers, misrepresents a commodity, or dilutes a mark,  whereas it bars the unauthorized duplication of copyrighted material in a wide variety of contexts, confusing, misrepresentative, or otherwise.  Considering the "substantial similarity" standard for a showing of [p. 419] copyright infringement to be broader than the "confusing similarity" required for trademark claims, courts have refused to consider trademark claims to material for which copyright claims have already failed.  This suggests that trademarks generally provide rights narrower in scope than copyrights and, therefore, that immortal trade dress rights would not unconstitutionally broaden the congressional power enumerated in the Intellectual Property Clause.
Nonetheless, a trademark generally does not cover the same subject matter as a copyright. The more it nears doing so, the more it risks overextending the effective life of the associated copyright. Consider Hartford House, in which granting trade dress rights in subject matter more appropriately covered by copyright gave rise to an infringement claim reaching beyond substantially similar copies.  Thanks to the virtual trade dress at work, Hartford House contradicts the general rule that the absence of an infringement claim under copyright law will bar an infringement claim under trademark law.  In re DC Comics, Inc.,  in which the trademark in question correlated exactly to the copyrighted image of Superman,  likewise proves instructive. Judge Nies, specially concurring, questioned "whether the quid pro quo for the protection granted under the copyright statute has been given, if, upon expiration of the copyright, the design can [p. 420] not be used at all by others."  Examples such as these demonstrate that, because it covers the same intrinsically valuable intellectual property that copyright covers, virtual trade dress effectively threatens to render a privileged class of copyrights immortal.
2. Virtual Trade Dress vs. Design Patent Law.Does trade dress similarly threaten to prolong the life of design patents? Again, case law suggests that, in general, it does not. Rather than barring trade dress protection in the same subject matter, a design patent offers rebuttable proof that its sibling trade dress is not functional.  More pointedly, despite broad language to the contrary in Supreme Court cases like Sears,  Compco,  and Kellogg Co. v. National Biscuit Co.,  courts have held consistently that trademark protection does not conflict with design patent protection.  The court in Kohler Co. v. Moen Inc.  justified its willingness to allow overlapping design patent and trademark rights by observing that while a patent gives "the exclusive right to make and sell the innovation, a trademark gives the owner [p. 421] only the right to preclude others from using the mark when such use is likely to cause confusion or to deceive." 
Although this distinction holds up well in product packaging cases,  it falters in product configuration cases.  Trade dress in product configuration cases comes uncomfortably close to constituting the very commodity that consumers value.  The protection that such trade dress grants against confusingly similar copies thus provides a far more valuable right than mere protection from confusingly similar packaging.
That a design patent theoretically prohibits all substantially similar copieswhether they confuse consumers or notoffers scant practical advantage. In the first place, design patents, arguably, only protect against unauthorized copies embodied in the same type of product. Because they aim at preventing consumer confusion,  trade dress rights have a similar scope. Nevertheless, even if design patent rights spread across product boundaries, it would matter little. Few people want to copy a faucet's design for anything other than a faucet, for example, nor would a patent holder especially care if someone applied the design to a tennis racquet. Furthermore, if such use offends, trade dress seems at least as likely to offer relief as does a design patent. After all, courts have found a likelihood of confusion sufficient to give rise to trademark infringement between such apparently unrelated products as magazines and girdles,  flashlights and locks,  pipes and Scotch whiskey,  and groceries and real estate.  The recent creation of a federal right against trademark dilution [p. 422] makes it even easier for a court to find that trade dress rights travel across product boundaries. 
Although a design patent theoretically offers unique protection against copies too clearly labeled to allow consumer confusion and, thus, an infringement claim for nonfamous trade dress this supposed benefit evaporates in practice. A disclaimer made clear enough to ward off confusion may so mar the design in question that it negates the benefits of honest copying. Hallmark would have won little in the Hartford House litigation,  for example, had the court allowed it to compete only on the condition that it stamp disclaimers across the front of the suspect cards. The risk of trade dress dilution claims and the willingness of courts to bar even clearly labeled cop- [p. 423] ies of trade dress  further whittle away at the supposed advantages of design patent protection. Virtual trade dress rights thus come very close, in practice, to creating potentially immortal design patents. 
3. Virtual Trade Dress vs. The Constitution. Suppose that virtual trade dress rights conflict with rights granted under copyright and patent law. Does that render virtual trade dress unconstitutional? In dicta, courts have often stressed that Article I, Section 8, Clause 8  empowers Congress to provide exclusive rights only of limited duration.  The court in Marx v. United States  directly grappled with the issue. To avoid the unconstitutional alternative of an everlasting copyright, the Marx court interpreted the 1909 Copyright Act  to impose a twenty-eight-year limit on the works in question.  "It is not to be assumed that a more extended measure of protection was intended," the court explained, because "[l]egislative enactments are to be construed, if possible, in such way as to render them constitutional."  [p. 424]
In a related vein, the court in Vornado Air Circulation Systems, Inc. v. Duracraft Corp.  barred trade dress protection of a product configuration on the grounds that to hold otherwise would effectivelyand unconstitutionallyrender a patent immortal. Commentators likewise agree that the Constitution prohibits Congress from passing statutes, or courts from giving effect to statutes, so as to create potentially unending copyrights or patents. 
4. Virtual Trade Dress vs. Congressional Intent.Beyond the fact that virtual trade dress violates a federal policy of assigning specific rights to and limitations on existing categories of intellectual property,  and may even violate the Constitution,  virtual trade dress contravenes the implied intent of Congress not to protect product designs. Congress has consistently and repeatedly refused to enact legislation to protect the same subject matter that, thanks to judicial fiat, virtual trade dress has come to protect.  As typically proves true in questions of policy, the several arguments against virtual trade dress still leave room for spirited public debate. That virtual trade dress runs counter to so many general policy considerations, however, in addition to legal doctrines specific to trade dress, amounts to damning criticism indeed. [p. 425]
Grappling with the doctrine of "aesthetic functionality" gives courts and commentators headaches.  Fortunately, the present analysis need not inflict similar discomfort. It suffices here to show that virtual trade dress does not represent simply another formulation of the aesthetic functionality problem. As the very commodity that consumers value, rather than mere ornamentation on something independently valuable, virtual trade dress merits condemnation on other, less controversial, grounds.
The United States Court of Appeals for the Ninth Circuit set forth the most well-known test for aesthetic functionality: "If the particular feature is an important ingredient in the commercial success of the product, the interest in free competition permits its imitation in the absence of a patent or copyright."  Other courts have criticized this doctrine.  The Ninth Circuit has thus partially retreated, explaining that it will not find an identifying mark functional, and, consequently, will not bar protection, solely on the grounds that the mark "contributes to the consumer appeal and saleability of the product." 
Virtual trade dress looks suspect under either the original or revised version of the Ninth Circuit's test of aesthetic functionality. Virtual trade dress goes much further than constituting an "important ingredient in the commercial success of the product"  or contributing "to consumer appeal and . . . the sale of the products." As the very commodity that consumers value, virtual trade dress represents the most important ingredient in a product's commercial success and saleability. Considering the strength of the doctrines discussed earlier,  however, courts need not rely on aesthetic functionality to rule out virtual trade dress. [p. 426]
It bears noting that McCarthy's suggested alternative to the aesthetic functionality doctrinethe traditional "merely ornamental" test may in practice fail to sort out virtual trade dress. McCarthy would have courts ask: "Is the disputed feature in fact perceived by customers as a trademark or not?"  If properly applied, this test might detect virtual trade dress in its infancy. Once it takes root, though, virtual trade dress resists extermination. As McCarthy notes elsewhere, courts sometimes mistake the popularity of an established design as evidence that it has acquired secondary meaning.  The merely ornamental test would thus feed a vicious cycle of monopolization by failing to condemn virtual trade dress that has, by dint of use under legal sanction, acquired secondary meaning.  As argued earlier, however, trade dress protection of an intrinsically valuable commodity merits condemnation because it violates established law and wise public policy. 
Although not responsible for encouraging abuse, the merely ornamental test does too little to prevent it. Courts need an independent arbiter of valid trade dress status. Courts should thus ask not only whether a design constitutes mere ornamentation on a commodity, but also whether the design constitutes the commodity itself. Only by taking this additional step can courts ward off the hazards of virtual trade dress.
Virtual trade dress raises issues similar to, though distinct from, a trademark or trade dress valued because it indicates affiliation with an independent good or service. Examples of the latter type of mark include the insignia of a fraternal organization  or the emblem of a sports team.  Judge Alex Kozinski has whimsically labeled such marks "unplugged" because they have "certain functional characteristics that are different fromand sometimes inconsistent withtheir [p. 427] traditional role as identifiers of source."  Calling these marks "autographic" sheds more light on their nature because, like a celebrity's signature, they both identify a source and establish positive associations with a related good or service. 
Although the case law addresses only autographic trademarks,  nothing bars trade dress from also acting in an autographic capacity. It need merely have sufficient secondary meaning to remind consumers of an affiliated good or service. Such (hypothetical) autographic trade dress would share some, but not all, of the features of virtual trade dress. Each has value without referring to the source of the particular commodity to which it attaches or that it embodies. In the case of autographic trade dress, for example, warm-up suits that mimic those worn by the University of Chicago football team would sell (assuming they did) not because consumers think that the sweats come from the Maroons, but rather because consumers want to look like the (original) "Monsters of the Midway." In other words, autographic trade dress, like virtual trade dress, does not identify residual hidden qualities. Furthermore, each type of trade dress risks invalidation on functional grounds because it has features that satisfy consumer demand.  [p. 428]
Autographic trade dress differs from virtual trade dress in vital respects, however. The value of autographic trade dress depends crucially on its affiliation with a particular source. People wore the once ubiquitous Batman T-shirt, for example, not to benefit from its intrinsic elegance but rather to associate themselves with the movie marketed under the same black and yellow symbol. Virtual trade dress, on the other hand, represents the very commodity that consumers desire. Autographic trade dress finds its analog in a celebrity's signature, desired for the cachet of fame. Virtual trade dress, in contrast, calls to mind a map scrawled by a helpful stranger for a lost traveler. The map proves helpful despite its anonymous source, whereas the stranger's signature counts for nothing. Virtual trade dress, unlike autographic trade dress, has intrinsic value.
This distinction between autographic trade dress and virtual trade dress has legal repercussions. Autographic trade dress ultimately draws its value from trademarks or trade dress operating in conventional manners in other contexts. Autographic trade dress thus raises a question of dilution.  Virtual trade dress bypasses these issues because its value does not rely on associations with conventional trademarks or trade dress.
If current trends continue, we may find courts awarding overbroad trade dress rights to computer-user interfaces and virtual environments. The designers of such software outputs have very strong incentives to protect their work and will aggressively seek out all possible means of doing so. Because virtual trade dress upsets existing categories of intellectual property, it threatens to throw off the present balance between rewarding creation and allowing competition. The following three hypothetical examples, drawn from After Dark (a screen saver program), Myst (a CD-ROM game), and Snow Crash  (a fictional account of a virtual reality), demonstrate the unjustifiably broad monopolies that trade dress might come to defend. [p. 429]
1. After Dark.A screen saver program projects changing images on a computer's video output after a predetermined length of time has passed since the computer user's most recent input.  Originally, these programs aimed at protecting computers' video tubes from image "burn-in."  Although technological advances have since rendered this function unnecessary, screen savers remain a popular source of entertainment.  "'A screen saver isn't a protective device anymore; it's a delivery method for content.'"  Those that create screen saver images view them, with some justification, as "'computer poetry.'" 
The most famous screen saver program, After Dark, features whimsical flocks of flying toasters. Suppose that the creator of After Dark, Berkeley Systems, Inc., claimed trade dress rights in the distinctive images  generated by its screen saver program. The claim seems quite plausible given precedent like Hartford House.  Its success would give Berkeley Systems potentially eternal rights over the use of these or similar images in potentially confusing contextsthat is, on computer screens.  Does that seem like a bit much? Blame virtual trade dress.
An up-and-running screen saver program provides little or no residual hidden value.  Take away the images that the program puts on the computer screen and you take away the very commodity that [p. 430] consumers value. Giving Berkeley Systems the sole right to those images (or confusingly similar or diluting variations of them) would thus give it the sole right to market a valuable product. Basing that right in trade dress would render it potentially immortal. No software manufacturer deserves so broad a claim to intellectual property.
Berkeley Systems may deserve some other sort of intellectual property rights in its flying toasters, of course. Current case law might bar it from obtaining a design patent in its images.  Berkeley Systems has already successfully asserted its copyright, however, to enjoin a rival screen saver that featured a cartoon character, Opus the Penguin, from firing a rifle at flying toasters.  Copyright should continue to protect the images in After Dark from substantially similar imitations for manythough fortunately not countlessyears.
2. Myst.Could Broderbund and Cyan win virtual trade dress rights to the CD-ROM game Myst?  Myst does offer a residual hidden commodity: a vast, maddening puzzle laced with clues.  A great portion of the pleasure of playing Myst comes from unraveling its mysteries, a commodity that remains very well hidden indeed. Myst also offers purely sensual delights, such as exotic, detailed images and haunting music.  Myst thus mixes experience commodities and inspection commodities, rather like the restaurants in Two Pesos and Fuddruckers. Those cases, as well as Romm Art, suggest that Broderbund and Cyan could get trade dress protection in their software's purely sensual aspects. As the analysis above argues, however, this would represent not real trade dress but rather virtual trade dress.  Myst's creators should thus get no more trade dress protection than that on the outside of their product's box or, perhaps, in the [p. 431] opening screens of their game.  Granting any more trade dress protection than this would give Broderbund and Cyan trade dress rights to the very product that consumers value.
3. Stephenson's Metaverse.Virtual reality has yet to see wide use or defining litigation, so we can only imagine how existing trade dress law would apply to this new technology. Neal Stephenson's science fiction novel, Snow Crash,  provides an especially useful tool for this exercise. It portrays several sorts of computer environments and thus serves as something like a virtual virtual reality.  Snow Crash includes descriptions of the Metaverse (an entirely on-line world)  and the Black Sun (a bar in the Metaverse). 
The Metaverse assumes the form of a huge black sphere.  Because the Metaverse serves as a common meeting ground for all manner of visitors, its dimensions were "fixed by a protocol, hammered out by the computer-graphics ninja overlords of the Association for Computing Machinery's Global Multimedia Protocol Group."  The characteristics of the Metaverse affect its function, supporting standards that allow a wide range of different types of software to interface in its environment. 
Because this packaging defines standards that serve a functional purpose, it would probably not win trade dress protection. As one commentary states: "Features that make a product easier to use, or even those that users might become accustomed to as a 'standard,' appear likely to be deemed functional and thus unprotectable."  Of course, the shape and appearance of the Metaverse may embody some other sort of intellectual property.  [p. 432]
More relevant to present purposes, this example demonstrates that virtual packaging may serve functional purposes more frequently than real-space packaging does. Thus, the former type of packaging should more frequently fail to qualify for trade dress protection.  In a world built solely of information, containers may serve as interfaces rather than as mere wrappers. In the Metaverse, for example, people swap databases by handing each other virtual hypercards. 
This confusion between appearances and functions also surfaces in a second example from Snow Crash: the Black Sun.  The Black Sun ranks as the hippest bar in the Metaverse, with a trade dress that tends toward the austere.  Its exterior presents a simple, squat, black pyramid.  Inside, "the decor consists of black, square tabletops hovering in the air (it would be pointless to draw in legs), evenly spaced across the floor in a grid." 
If the Black Sun's architecture and design served solely as decoration, it would probably win the same trade dress protection as its real-space counterparts, the Two Pesos and Fuddruckers restaurants. It would likewise raise the same questions about overextending trade dress rights. It looks as if the Black Sun's architecture says more about economics than aesthetics, however. Stephenson explains that the hackers who "wrote" the Black Sun "didn't have enough money to hire architects or designers, so they just went in for simple geometric shapes."  Likewise, the interior decor of the Black Sun appears to serve a functional purpose: "Everything is matte black, which makes it [p. 433] a lot easier for the computer system to draw things in on top of itno worries about filling in a complicated background." The simple interior and exterior design of the Black Sun thus does more than merely create a cyberpunk atmosphere.  It also reduces the computational burdens of creating and running the Black Sun, and, presumably, the proprietors' costs.  Does this render trade dress law inapplicable? Probably not.
The Black Sun's competitors would have many alternative geometric shapes and matte color backgrounds from which to choose. The Black Sun's owners also could argue forcefully that, as in Two Pesos and Fuddruckers, these individually functional elements combine to create a nonfunctional whole. Furthermore, like the restaurants in Two Pesos and Fuddruckers, the Black Sun offers more than mere decor; its built-in software expels disruptive and infectious guests, making the Black Sun a popular and safe meeting place. 
Nevertheless, any claim to the Black Sun's trade dress would still cover a good deal of the same productthe hip noir atmospherethat its customers value. The proprietors of the Black Sun could thus win virtual trade dress rights to intrinsically valuable features of their service and wield those rights against competing hot spots. Indeed, the rush to grab rights to the Black Sun's trade dress has already started; Viacom New Media has announced a forthcoming CD-ROM action-adventure game based on Stephenson's Snow Crash.  Viacom claims that it has "attempted to retain the book's flavor by keeping core elements of the Metaversesuch as the Black Sun,"  and prerelease screen shots from the game indicate that it aims to recreate Stephenson's imagery.  Arguments that these types of game environments operate as trade dress should soon follow.
These examples from After Dark, Myst, and Snow Crash illustrate that the brave new world of virtual reality holds significant potential for the abuse of trade dress law. In any circumstance in which consumers value a virtual environment for its aesthetic qualities, overbroad trade dress claims threaten to provide unduly expansive and [p. 434] long-lived intellectual property rights. These circumstances will surely increase as computer interfaces and virtual environments become more detailed, realistic, and beautiful. We should expect to see virtual environments evolve into something like architecture: pleasant and universally accessible backdrops for the more active pursuits of work and play. In this capacity, virtual environments will, like the cards in Hartford House or the prints in Romm Art, stand alone as desiderata and identify no other commodity. These virtual environments should not win trade dress protection.
1. Intrinsic Limits on Virtual Trade Dress.Despite the risks it poses, virtual trade dress does not threaten to entirely consume intellectual property rights in virtual reality. First, rights to a particular trade dress might fail to protect individual functional elements that combine to create it. It seems likely that many aspects of on-line environments will serve as standards or functional interfaces, thus disqualifying them from trade dress protection. Of course, trade dress does cover unique configurations of individually functional elements.  Virtual trade dress could thus provide a monopoly on a particular style of World Wide Web page, for example, if not the particular buttons built into it.
Second, virtual trade dress would not protect in their entirety digital environments that qualify as functional. Increasingly, people work as well as play on-line.  Commercial services will find it difficult to claim trade dress rights in the same environments that they tout as functional. In advertising, "You'll access data faster in our DigitaLibrarytm!", for example, a service provider would undermine its trade dress rights to the very features of which it boasts.
Finally, some commentators have argued that trade dress protection suffers comparative disadvantages to copyright protection.  Moreover, in some circumstances, the likelihood of confusion test of trade dress infringement might offer less coverage than the substantial similarity test of copyright infringement.  The defendant in a copyright infringement suit gains little, for example, by having affixed [p. 435] disclaimers to inform consumers of the actual source of offending copies.  In a similar vein, the same derivative work that infringes a copyright could pose too low a risk of confusion to support a trade dress infringement claim.  Note, however, that copyright protection might fail to cover the most important aspects of virtual environments; it looks increasingly doubtful that copyright law protects the "look and feel" of computer interfaces. 
2. Curbing Virtual Trade Dress.Despite some inherent limitations, virtual trade dress remains a problem. Courts can curb it, however, through a variety of measures. Courts should simply refuse to recognize claims to pure virtual trade dress. They can detect it by asking if the claimed trade dress in fact constitutes the commodity that consumers value and then disallow it as either functional, inherently nondistinctive, or both. 
In many cases virtual trade dress will come mixed with the real thing. Given the importance of free competition, courts should avoid foreclosing all access to the trade dress in question. Courts should thus force competitors to apply just enough disclaimers and labeling to ward off consumer confusion.  Furthermore, courts should demand less labeling from defendants as the trade dress in question falls more heavily on the virtual side of the scale. Requiring disclaimers not only hinders competition by increasing defendants' costs, in the case of virtual trade dress, it can hinder competition by rendering the commodity in question less valuable. For example, had Hallmark es- [p. 436] caped the Hartford House litigation with only a disclaimer requirement, forcing Hallmark to stamp a disclaimer in bold, red letters across the face of offending cards would have effectively foreclosed competition.
In product design cases mixing real and virtual trade dress, courts should also require the plaintiff to show secondary meaning.  Although Two Pesos allows courts to find trade dress inherently distinctive,  these courts should not seize on this option with regard to trade dress that includes the very commodities that consumers value. To the extent that trade dress itself represents a desideratum, consumers cannot distinguish it from what the trade dress supposedly identifies,  nor will any amount of use in commerce change that fact. 
Virtual reality offers exciting new worlds not only for people, but also for legal doctrines. Its liberating and disorienting sweep will challenge usand our lawsto adapt quickly. The sooner that we can identify and prevent potential problems, the better. On these grounds alone, virtual trade dress qualifies for eradication. Even apart from its dark potential, however, virtual trade dress poses problems right now.
Despite its pedigree in influential cases, virtual trade dress stands on shaky ground. Not one of the economic justifications that support conventional trade dress rights applies to trade dress that has intrinsic value. Moreover, virtual trade dress fails to meet the traditional legal standards of nonfunctionality and distinctiveness. Policy considerations leave such trade dress looking unwise; legal considerations might even render it unconstitutional. [p. 437]
Virtual environments no doubt qualify for protection from theft and copying. Copyrights, licenses, design patents, and various technological fixes can do most of that work. Even trademark law has a role, albeit one far smaller than a few errant courts have allowed. In virtual reality, as elsewhere, trademarks and trade dress ought to do no more than identify a commodity's source, and not do so much as to unduly limit competition. Virtual trade dress thus already represents an aberration of trademark law. If current legal and technological trends continue, moreover, virtual trade dress could become a very real problem.

The Tenth Circuit claimed that because "the district court specifically listed the combination of features that comprise Blue Mountain's protected trade dress, Hallmark is guided as to what features combined may create a confusingly similar product." Hartford House, 846 F.2d at 1275. The court confused the issue, however, by stating that "some or all" of the features listed by the district court comprised the overall look of the Blue Mountain product. Id. at 1270. This ambiguous determination leaves the scope of Blue Mountain's trade dress rights quite vague.
. This being prior to Two Pesos, the court required Hartford House to prove the distinctiveness of its trade dress through a showing of secondary meaning. Two Pesos opened the door to showing simply that trade dress has inherent distinctiveness. See infra notes 101-108 and accompanying text.

. Blue Mountain could undoubtedly have asserted a copyright against substantially similar copies of its cards, though Hallmark presumably made its cards too dissimilar to support such a claim. As an alternative to copyright or trade dress protection, could Blue Mountain have won a design patent? The United States Patent and Trade Office apparently regards a greeting card as an "article of manufacture" under 35 U.S.C. § 171 (1994). See Pioneer Photo Albums, Inc. v. Holson Co., 654 F. Supp. 87, 88 (C.D. Cal. 1987) (invalidating design patent in greeting card on other grounds). Blue Mountain's hypothetical design patent would cover only its designs as embodied in its cards. Cf. Ex parte Tayama, 24 U.S.P.Q.2d 1614, 1616 (Bd. Pat. App. & Int'f. 1992) ("[A] picture standing alone is not protectable by a design patent."); In re Schnell, 46 F.2d 203, 209 (C.C.P.A. 1931) ("[D]esign must be shown not to be the mere invention of a picture . . . but . . . should be required to show . . . the manner of its application.").

. For example, in Duraco, 40 F.3d at 1431, the Third Circuit stated: "[W]e do not think it helpful or proper to transplant the categorical distinctiveness inquiry developed for trademarks to product configurations, where the alleged trade dress lies in the very product itself." Id. at 1440. The court reasoned:
[I]nsofar as consumer motivation to purchase a product will much more likely be predicated on an appreciation of a product's features than on an appreciation of a product's name, assuming no secondary meaning attached to either, one cannot automatically conclude from a product feature or configurationas one can from a product's arbitrary name, for examplethat, to a consumer, it functions primarily to denote the product's source.Id. at 1441.
. See infra Parts VI.B.2-C.
. See infra Part VI.C.1.
. The United States Court of Appeals for the Tenth Circuit instead asked whether Blue Mountain had "been granted exclusive rights in an artistic style or in some concept, idea, or theme of expression." Hartford House, Ltd. v. Hallmark Cards, Inc., 846 F.2d 1268, 1274 (10th Cir. 1988) (footnote omitted). Having framed the issue in such bloated terms, the court concluded: "This protection does not extend the protection available under trademark law and does not conflict with the policy of copyright law." Id.
. See Duraco, 40 F.3d at 1447 ("We believe that courts should exercise restraint so as not to undermine Congress's repeated determinations not to afford virtually perpetual protection to product configurations with an expansive construction of section 43(a).").

. One might argue that Blue Mountain's trade dress identifies the cards from a distance, allowing shoppers to zero in on the card rack holding their favorite brand. Trade dress would thus reveal the value hidden by distance. This argument fails, however, because it (1) assumes that Blue Mountain deserves a monopoly in its product and (2) disregards the fact that consumers still have ample opportunity to inspect the cards prior to purchase.

McCarthy, supra note 37, § 6.04, at 6-27 n.20. Curiously, as his use of "unique" indicates, McCarthy exempts Hartford House from similar criticism. See id.

. See Michael R. Darby & Edi Karni, Free Competition and the Optimal Amount of Fraud, 16 J.L. & Econ.. 67, 68-69 (1973) (referring to characteristics of a purchase as "experience" qualities when they "can be discovered only after purchase as the product is used," and as "credence" qualities, which cannot be determined even in normal use after purchase). A third category of goods, "search" goods, possesses qualities that consumers can detect prior to purchase. See Phillip Nelson, Information and Consumer Behavior, 78 J. Pol. Econ. 311, 312 (1970) (defining "search" as any way of evaluating price or quality options open to the consumer, when the consumer inspects the option prior to purchasing the brand). Even here, trademarks and trade dress can help to lower information costs. The present discussion, however, primarily concerns a subclass of search goods for which information costs approach zero: inspection goods.
. See William M. Landes & Richard A. Posner, The Economic Structure of Tort Law 284-85 (1987); Darby & Karni, supra note 137, at 68-69; Nelson, supra note 137, at 321-23.
. Trademarks help define credence goods only indirectly and only insofar as they get packaged as experience goods. Suppose an authority reports that vitamin E extends life span, making it a credence good, and a manufacturer puts vitamin E capsules in opaque bottles. The manufacturer's trademark on the opaque bottles identifies not vitamin E per se, but rather only its capsules, which qualify as experience goods relative to other manufacturers' capsules.
. See Landes & Posner, supra note 136, at 268-69, 275.
. See id. at 269.
. It bears noting that this function has nothing to do with encouraging innovation, fundamentally distinguishing trademark law from patent and copyright law. Courts have sometimes overlooked this distinction. See, e.g., Keene Corp. v. Paraflex Indus., Inc., 653 F.2d 822, 825 (3d Cir. 1981) (criticizing the aesthetic functionality doctrine on the grounds that it discourages imaginative and attractive marks); Hartford House, Ltd. v. Hallmark Cards, Inc., 647 F. Supp. 1533, 1540 (D. Colo. 1986) ("One salutary purpose of the Lanham Act . . . is to protect a creative artists' [sic] rights in his or her creation and thus provide incentive to be creative."), aff'd, 846 F.2d 1268 (10th Cir. 1988). The court in Duraco Products, Inc. v. Joy Plastic Enterprises, Ltd., 40 F.3d 1441, 1446 (3d Cir. 1994), among others, recognized the fault in such views. See supra Part III.C; see also Qualitex Co. v. Jacobson Prods. Co., 115 S. Ct. 1300, 1304 (1995) ("It is the province of patent law, not trademark law, to encourage invention . . . ."); Gleiberman, supra note 6, at 2056-57 (noting that trademark law is not designed to encourage creativity in product design).
. To speak more comprehensively, trademarks add less value to goods that have fewer hidden qualities. This pragmatic hedge accommodates an argument that Dan L. Burk made when commenting on an earlier draft of this Article: Every commodity has some hidden qualities; inspection, experience, and credence goods thus differ only in how rapidly consumers can assess them. Even granting Burk's argument, however, it remains true that the costs of protecting trademarks in inspection goods almost always outweigh the benefits.
. See Landes & Posner, supra note 138, at 284. Landes and Posner equate inspection goods with search goods generally, commenting that in the nineteenth century, a consumer could detect the qualities of such goods at low cost. See id. They correctly note, however, that now some search goods reveal their qualities only at high cost (albeit prior to purchase). See id. at 285 (explaining that "[t]he growth in the technical complexity of products" and consumers' lack of technical knowledge has increased search costs); see also Nelson, supra note 137, at 312 (noting that if search procedures are too costly, consumers might employ experience procedures). The present text thus reserves "inspection" for goods that reveal their qualities at little or no cost, prior to purchase.
. Why, then, does Hallmark advertise the significance of its mark? To draw consumers to its racks and to suggest slyly that recipients can use its mark as a proxy for the senders' expenses.
. This analysis suggests an interesting way to regard the purpose of trademarks, service marks, and, by extension, trade dress: by revealing hidden qualities, they aim at making all goods more functionally equivalent to inspection goods.
. Landes & Posner, supra note 136, at 270.
. Despite the broad language of 15 U.S.C. § 1125(a) (1994), allowing "any person who believes that he is or is likely to be damaged by" violation of its terms, courts are divided on whether to give consumers standing to sue. Compare Colligan v. Activities Club, 442 F.2d 686 (2d Cir. 1971) (standing denied), with Arnesen v. Raymond Lee Org., Inc., 333 F. Supp. 116 (C.D. Cal. 1971) (standing allowed).

. Copying can prove quite expensive in absolute terms. Consider for example, the costs of copying a restaurant's architecture, decor, and service.

The Federal Circuit has staked out an intermediary position. See Textron, Inc. v. United States Int'l [p. 416] Trade Comm'n, 753 F.2d 1019, 1025 (Fed. Cir. 1985) (finding that a party seeking protection has the burden of proving nonfunctionality, but only after opponent makes prima facie case for functionality). The Eleventh Circuit has expressly declined to resolve who bears the burden of proving functionality. See John H. Harland Co. v. Clarke Checks, Inc., 711 F.2d 966, 982 n.26 (11th Cir. 1983) (finding that the issue was not reserved for appeal). Thus far, the Supreme Court has done little more about this split than to observe, in a concurrence, that "functionality is a defense to a suit under § 43(a) of the Lanham Act." Inwood Lab., Inc. v. Ives Lab., Inc., 456 U.S. 844, 863 (1982) (White, J., concurring).
Questions about the burden of proving functionality properly arise only with regard to unregistered trade dress, of course, as registered marks enjoy a presumption of validity. See 15 U.S.C. § 1115(a) (1994); see also Aromatique, Inc. v. Gold Seal, Inc., 28 F.3d 863, 869 (8th Cir. 1994) (holding that the presumption of validity is rebuttable).

. See 35 U.S.C. § 171 (1994), which specifies that only a "new, original and ornamental design for an article of manufacture" will qualify for design patent protection. Id. (emphasis added).

The owner of a famous mark shall be entitled, subject to the principles of equity and upon such terms as the court deems reasonable, to an injunction against another person's commercial use in commerce of a mark or trade name, if such use begins after the mark has become famous and causes dilution of the distinctive quality of the mark, and to obtain such other relief as is provided in this subsection. In determining whether a mark is distinctive and famous, a court may consider factors such as, but not limited to -Id. § (c)(1).(A) the degree of inherent or acquired distinctiveness of the mark;
(B) the duration and extent of use of the mark in connection with the goods or services with which the mark is used;
(C) the duration and extent of advertising and publicity of the mark;
(D) the geographical extent of the trading area in which the mark is used;
(E) the channels of trade for the goods or services in which the mark is used;
(F) the degree of recognition of the mark in the trading areas and channels of trade used by the marks' owner and the person against whom the injunction is sought;
(G) the nature and extent of use of the same or similar marks by third parties; and
(H) whether the mark was registered under the [Trade-Mark] Act of March 3, 1881, or the [Trade-Mark] Act of February 20, 1905, or on the principal register.

The monopoly privileges that Congress may authorize are neither unlimited nor primarily designed to provide a special private benefit. Rather, . . . [they serve] to motivate the creative activity of authors and inventors by the provision of a special reward, and to allow the public access to the products of their genius after the limited period of exclusive control has expired.Id. at 429 (emphasis added).

In an age when fashion-conscious consumers wear T-shirts emblazoned with the trademarks of consumer products and owners of Volkswagens buy conversion kits to enable them to put a Rolls Royce grille on their car, it is apparent that trade names, symbols, and design features often serve a dual purpose, one part of which is functional in the sense of making the product more attractive, and is distinct from identifying the manufacturer or his brand to the consumer.Id. at 340.
. Celebrity signatures can also attain value by merit of their scarcity, however. The metaphor thus works best if one understands the term "autograph" to include copies of signatures, which often appear in advertisements touting celebrity endorsements.
. See, e.g., Job's Daughters, 633 F.2d 912; Kentucky Fried Chicken Corp. v. Diversified Packaging Corp., 549 F.2d 368 (5th Cir.1977) (trademark in chicken franchise's containers and accouterments); Boston Prof'l Hockey Ass'n, 510 F.2d 1004 (trademark emblem of professional sports team); University of Pittsburgh v.

. See, e.g., Job's Daughters, 633 F.2d at 917 (finding that a feature is functional if it constitutes "the actual benefit that the consumer wishes to purchase, as distinguished from an assurance that a particular entity made, sponsored, or endorsed a product"); Champion, 566 F. Supp. at 720-21 (finding that the university's insignia is a functional element of shirts). But see, e.g., Boston Prof'l Hockey Ass'n, 510 F.2d at 1012 ("The argument that confusion must be as to the source of the manufacture of the emblem itself is unpersuasive, where the trademark, originated by the team, is the triggering mechanism for the sale of the emblem.").

. In truth, the images are perhaps not so distinctive. In October 1994, representatives of the defunct rock group Jefferson Airplane sued Berkeley Systems, Inc. for copyright infringement, claiming that the image of flying toasters came from the cover of the group's 1973 album, Thirty Seconds over Winterland. The federal district court hearing the suit dismissed it on grounds that the group's copyright covered only its sound recording. See Corp. Legal Times, Jan. 1995, at 34.

. The new federal right against dilution of famous marks would, of course, merely increase the opportunity for obtaining such monopolies. See 15 U.S.C.A. § 1125(c) (West Supp. 1997).
. Tom G. Palmer has argued, in conversation with the Author, that screen saver programs can possess residual hidden values, such as operating system compatibility and providing freedom from computer viruses. Conventional trademarks and trade dress suffice to identify these traits, however, at the program's point of sale. Images generated during the screen saver's operation thus offer very little additional information.
. See Ex parte Strijland, 26 U.S.P.Q.2d 1259, 1263 (Bd. Pat. App. & Int'f. 1992) (holding that an applicant for a design patent in a computer icon must show that the claimed element constitutes an active component in the operation of the computer, and not merely a "displayed picture," by showing, for example, that clicking on or otherwise manipulating the element initiates functional operations). But see Ken Liebman et al., The Shape of Things to Come: Design-Patent Protection for Computers, 9 No. 11 Computer Law. 1, 4 (1992) (criticizing the approach in Ex parte Strijland as effectively rendering the claimed element functional and thus unworthy of design patent protection).

. Liebman et al., supra note 5, at 5.
. Note that as a standard format it may also fail to win protection under copyright law. See, e.g., Lotus Dev. Corp. v. Paperback Software Int'l, 49 F.3d 807, 816 (1st Cir. 1995) (holding menu command hierarchy an uncopyrightable method of operation), aff'd per curiam, 116 S.

Altai, Inc., 982 F.2d 693, 707-08 (2d Cir. 1992) (arguing that certain structural elements of computer programs are ideas and not expressions and, therefore, cannot be copyrighted); Plains Cotton Coop.

Goodpasture Computer Serv., Inc., 807 F.2d 1256, 1262 (5th Cir. 1987) (denying an injunction against the use of a computer program on the basis that it was not copyrightable); Synercom Tech., Inc. v. University Computing Co., 462 F. Supp. 1003, 1014 (N.D. Tex. 1978) (holding that the input formats of computer programs are ideas and not expressions and, therefore, not copyrightable). The Supreme Court's enigmatic, deadlocked affirmance in Lotus failed to completely settle this area of copyright law, however, arguably leaving the circuits split. See, e.g., Whelan Assocs., Inc. v. Jaslow Dental Lab., Inc., 797 F.2d 1222, 1240 (3d Cir. 1986) (concluding that the structure of a computer program is part of the expression of the program and not the idea and is, therefore, copyrightable).
. The bar on functional trade dress represents not a statutory doctrine, but rather a judicial one. See In re Morton-Norwich Prods., Inc., 671 F.2d 1332, 1336 (C.C.P.A. 1982) ("This requirement of 'nonfunctionality' is not mandated by statute, but 'is deduced entirely from court decisions.'").

Cir. 1995) (affirming the verdict of trade dress dilution under New York law of furniture having a nautical look); Dallas Cowboys Cheerleaders, Inc. v. Pussycat Cinema, Ltd., 604 F.2d 200(2d Cir. 1979) (affirming a preliminary injunction barring dilution under New York law of cheerleader uniform).
. Again, such a derivative work may give rise to a trade dress dilution claim. See 15 U.S.C.A. § 1125(c) (West Supp. 1997).
. See supra note 294; see also John Hornick, Computer Program Copyrights: Look and Feel No Evil, 5 Software L.J. 355, 355 (1992) ("[T]he extent to which copyright protection extends to its nonliteral elements, such as . . . its so-called look and feel, is still unclear."); Jack Russo & Jamie Nafziger, Software "Look and Feel" Protection in the 1990s, 15 Hastings Comm. & Ent.

Stiffel Co., 376 U.S. 225, 232-33 (1964) (holding that a state may make appropriate labeling laws to "prevent customers from being misled as to the source," but may not prohibit the copying of unpatented or uncopyrighted articles); Esercizio v. Roberts, 944 F.2d 1235, 1250 (6th Cir. 1991) (Kennedy, J., dissenting) ("The proper remedy is to require identification of the source of the replica, not prohibit copying of the product.").
. See Gaske, supra note 67, at 1139 (arguing that finding secondary meaning is the only appropriate test in these cases because the inherent distinctiveness test "improperly expands trade dress protection into areas reserved for copyrights and patents").
. Two Pesos, Inc. v. Taco Cabana, Inc., 505 U.S. 763, 769 (1992).
. See supra Part VI.B.1.
. Note, however, the Supreme Court's statement in Two Pesos that "the general principles qualifying a mark for registration under § 2 of the Lanham Act are for the most part applicable in determining whether an unregistered mark is entitled to protection under § 43(a)." Two Pesos, 505 U.S. at 768 (citations omitted). Section 1052(f) of 15 U.S.C. provides that in considering a mark for registration "[t]he Commissioner may accept as prima facie evidence that the mark has become distinctive . . . proof of substantially exclusive and continuous use thereof . . . for the five years before the" registrant's claim of distinctiveness. 15 U.S.C. § 1052(f) (1994). Perhaps a trade dress claimant could cite Two Pesos and section 1052(f) in an argument to force a court to consider secondary meaning. A counterargument: The Commissioner and courts routinely read into the preamble to section 1052 a bar on generic marks. As noted supra Part VI.B.1., virtual trade dress qualifies, in some sense, as even less distinctive than generic.
