I want to thank Bill Barber, Tom Cotter, Robert Denicola, Graeme Dinwoodie, Mark Lemley, Glynn Lunney, and William Page for their helpful comments on an early draft of this Article. My research assistant, Henry Rodriguez, provided invaluable assistance in gathering and reviewing the many works on the functionality doctrine. My work on this project was aided by the Levin College of Law’s summer research grant program. 243 244 FLORIDA LAW REVIEW [Vol. 56 1.

CONCLUSION ......................................370 Trademark law’s functionality doctrine is a mess, and the responsibility for this mess rests squarely with the United States Supreme Court. In TrafFix Devices, Inc. v. Marketing Displays, Inc. ,1 the Supreme Court intervened to resolve a minor split on a secondary functionality issue, 2 and proceeded to recast the entire law of functionality. In so doing, the Court summarily rejected the general functionality standard used by every circuit court of appeals prior to the TrafFix decision. The TrafFix Court simply declared the existing law “incorrect,” 3 and replaced it with an unwieldy, unjustified, and unworkable set of rules. The mess created by the TrafFix Court is troublesome. The functionality doctrine is perhaps the most important limitation on 1. 532 U.S. 23 (2001). 2. See id . at 28. 3. Id . at 33. 2004] TRADEMARK LAW’S FUNCTIONALITY DOCTRINE 245 trademark protection for product configurations and packaging. 4 A functional product feature cannot be protected as a trademark. 5 This statement of black letter law illustrates both the importance and the crux of the difficulty posed by the functionality doctrine. It is important because how we define functionality will directly affect the range of symbols that may be protected as trademarks. It is difficult because persons with different views on the propriety of trademark protection for attributes such as product configuration or product color are likely to push for different functionality standards. In the TrafFix decision, the Court rejected a competition-based definition of functionality, 6 but failed to provide a clear alternative definition. Within one year of the TrafFix decision, the lower federal courts divided on the crucial question of what general functionality standard should be used. 7 The Court of Appeals for the Federal Circuit concluded 4. Some may disagree with this proposition, arguing instead that distinctiveness is a more significant limitation on trademark protection. I view distinctiveness not as a limitation, but rather as a definitional requirement. To be a trademark, a symbol must be distinctive. Nondistinctive symbols are simply not trademarks, so it seems wrong to discuss distinctiveness as a limitation on the scope of protection afforded to trademarks. Having made this clarification, I also believe that distinctiveness should be a significant filtering requirement of trademark law. See infra notes 505- 12 and accompanying text. 5.

Weinberg, Trademark Law, Functional Design Features, and the Trouble with TrafFix, 246 FLORIDA LAW REVIEW [Vol. 56 that TrafFix did not change the general functionality standard.8 This reading is particularly significant because the United States Patent and Trademark Office (PTO) is bound by the decisions of the Federal Circuit on such issues. 9 The PTO, therefore, is still using a competition-based functionality standard when evaluating applications to register trademarks. 10 Other courts, however, have read TrafFix as radically changing the law. 11 These courts now equate functionality with utility, a standard very different from the competition-based standard in use prior to TrafFix .12 To appreciate the significance of this split, consider the shape of a plastic spray bottle like the one used with Fantastik® cleaner or Spray ‘N Wash® laundry stain treatment.
