Honorable John F. Nangle, Senior U.S. District Judge for the Eastern District of Missouri, sitting by designation.

("Pudenz"), invalidating two of Littlefuse's federally registered trademarks, and denying Littlefuse's counterclaims against Pudenz based on those marks for unfair competition and unlawful importation of goods. On appeal, this case raises the following issue: whether a federally registered trademark that has achieved incontestable status may nonetheless be declared invalid based on the functionality doctrine. We hold that registered trademarks that have become incontestable under 15 U.S.C. § 1065 may still be declared invalid if they are found to protect the functional features of a product, and therefore AFFIRM.

I. BACKGROUND

Littlefuse and Pudenz are both companies that manufacture and market, among other electronic devices, plug-in blade fuses for automobiles. Littlefuse and its licensees sell nearly 100% of the automotive blade fuses sold in the United States. Pudenz, a German company, has a significant share of the European market for automotive blade fuses and has started to enter the American market. Both companies market their fuses primarily to automobile and automobile parts manufacturers, but also sell fuses to aftermarket purchasers such as car owners.

As part of its product line, Littlefuse produces and markets an automotive fuse called the ATO blade fuse. At issue in this case are two of Littlefuse's registered trademarks associated with the marketing of this fuse. The first is the subject of U.S.

Trademark Registration Number 1,513,357 (the "'357 registration"), which covers the two-dimensional outline of the ATO fuse. The second is the subject of U.S. Trademark Registration Number 1,553,579 (the "'579 registration"), which covers the three-dimensional configuration of the ATO fuse housing. As the registrations show and Littlefuse's counterclaims make clear, both registrations seek to protect the configuration of the ATO fuse as trade dress. Both registrations have also achieved "incontestable" status pursuant to 15 U.S.C. § 1065.1 In 1995, Littlefuse sent Pudenz a cease and desist letter, alleging that the configuration of Pudenz's FKS and FK2 automotive blade fuses (the "FK fuses") infringed the registered trade dress of the Littlefuse ATO fuses as set forth in their trademark registrations. The letter demanded that Pudenz refrain from importing the FK fuses into the United States. In response, Pudenz initiated this lawsuit by filing a Complaint for a declaratory judgement that the FK fuses did not infringe any of Littlefuse's trademark rights. In its Answer, Littlefuse filed counterclaims against Pudenz and Pudenz's United States distributor, Wickmann USA, Inc. ("Wickmann"), for infringement of the ATO fuse trade dress as set forth in the '357 and '579 registrations, for federal unfair competition, and for unlawful importation under 15 U.S.C. § 1124 and 19 U.S.C. § 1526.

Littlefuse moved for summary judgment on its counterclaims. The district court denied the motion, holding (1) that functionality may be raised as a defense in actions based on incontestable trademark registrations; (2) that Pudenz established a genuine factual dispute as to the functionality of the ATO trade dress; and alternatively (3) that there was a genuine factual dispute as to the

1 Under this provision of the Lanham Act, a trademark registration may become incontestable if and when the mark has been in continuous use for 5 years after the initial registration, there is no pending challenge to the validity of the mark, and the registrant files an affidavit with the Commissioner of Patents within one year after the expiration of the initial five-year period, affirming that the mark is still in use. 15 U.S.C. § 1065.

likelihood of confusion created by the configuration of the FK fuses. The case then proceeded to trial before the district court. On January 7, 1998, the court issued a Judgement and Order granting declaratory relief to Pudenz and denying Littlefuse's claims. After finding that both the individual features of the ATO fuse housing and the overall configuration of those features in the housing itself were functional, the court held and declared that this functionality rendered the '357 and '579 registrations invalid and unenforceable. In the alternative, the court held that even if the registrations were valid, the FK fuses did not infringe the trade dress of the ATO fuses.2 Littlefuse filed timely notice of appeal, and we have jurisdiction pursuant to 28 U.S.C. § 1291.

II. STANDARD OF REVIEW

The applicability of the functionality doctrine to a trademark that is the subject of an incontestable registration is a question of law. As such, we review the district court's determination de novo. See McBride v. Sharpe, 25 F.3d 962, 968 (11th Cir. 1994).

III. DISCUSSION

A. The Functionality Doctrine The functionality doctrine is a judicially created rule that predates the Lanham Act. Under this rule, no trademark rights may be claimed in a product's functional shapes or features. 1 J. Thomas McCarthy, McCarthy on Trademarks and Unfair Competition, § 7:63 (4th ed. 1997); See Epic Metals Corp. v. Souliere, 99 F.3d 1034, 1038 (11th Cir. 1996)("A products features are

2 The district court so held based on a finding that the configuration of the FK fuses did not create a likelihood of confusion. Because we affirm the invalidity of the trade dress based on the functionality doctrine, we need not address the merits of the claims based on those invalid trademarks.

protectible as trade dress if they are primarily non-functional."). This proscription serves two purposes. First, by ensuring that competitors remain free to copy useful product features, it prevents the trademark law from undermining its own pro-competitive objectives. Qualitex Co. v. Jacobson Products Co., Inc., 514 U.S. 159, 164, 115 S.Ct. 1300, 1304, 131 L.Ed.2d 248 (1995). Second, the functionality doctrine prevents the trademark law from conflicting with the patent law by eliminating trademark monopolies of potentially unlimited duration on a product's utilitarian features. Id., at 165.

This second rationale is particularly important. The federal government's power to grant patents flows from the Patent Clause of the Constitution. This clause grants Congress the power "to promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive right to their respective writings and discoveries." U.S. Const. art. I, § 8, cl. 8. The Supreme Court has noted that this clause contains both a grant of power to the government, as well as a limitation upon that power. Bonito Boats, Inc. v. Thunder Craft Boats, Inc., 489 U.S. 141, 146, 109 S.Ct. 971, 975, L.Ed.2d 118 (1989). Notably, the Patent Clause explicitly requires that the inventor's exclusive right, embodied in a granted patent, must be of a limited duration. Thus, the Constitution strikes a balance between the encouragement of innovation and the establishment of a public domain of freely available inventions to foster competition. Id.

The Supreme Court has explained the importance of this balance and the constitutional underpinnings of the public domain:
