Compco Corp. v. Day-Brite Lighting, Inc., 376 U.S. 234, 84 S.Ct. 779, 11 L.Ed.2d 669, 140 U.S.P.Q. 528

Facts

This case involves a dispute between Compco Corp. and Day-Brite Lighting, Inc. regarding the infringement of a design patent and allegations of unfair competition. Day-Brite had secured a design patent for a lighting fixture but was later found to have an invalid patent. Compco began selling similar fixtures, leading Day-Brite to claim that Compco's actions caused confusion among consumers regarding the source of the products. The District Court ruled in favor of Day-Brite on the unfair competition claim, but the validity of the design patent was not upheld.

Day-Brite in 1955 secured from the Patent Office a design patent on a reflector having cross-ribs claimed to give both strength and attractiveness to the fixture. Day-Brite also sought, but was refused, a mechanical patent on the same device. After Day-Brite had begun selling its fixture, Compco's predecessor began making and selling fixtures very similar to Day-Brite's.

Issue

Whether the use of state unfair competition law to provide relief against the copying of an unpatented industrial design conflicts with federal patent laws.

Whether the use of state unfair competition law to give relief against the copying of an unpatented industrial design conflicts with the federal patent laws.

Rule

Under federal patent laws, when an article is unprotected by a patent or copyright, state law cannot prohibit others from copying that article. This principle is rooted in the constitutional provision allowing free access to copy what is left in the public domain by federal patent and copyright laws. However, states can impose liability on those who mislead the public by misrepresenting their products as originals.

Analysis

The court analyzed the facts surrounding the case, noting that while Compco's fixtures were similar to Day-Brite's, the mere act of copying an unpatented design does not constitute unfair competition under federal law. The court emphasized that the state cannot impose restrictions on copying unless there is a valid state law requiring such precautions. The evidence presented did not sufficiently demonstrate that Compco's actions were misleading or deceptive to consumers.

Even accepting the findings, we hold that the order for an accounting for damages and the injunction are in conflict with the federal patent laws. Today we have held in Sears, Roebuck & Co. v. Stiffel Co., 376 U.S. 225, 84 S.Ct. 784, that when an article is unprotected by a patent or a copyright, state law may not forbid others to copy that article.

Conclusion

The Supreme Court reversed the lower court's ruling, stating that the order for an accounting for damages and the injunction against Compco were in conflict with federal patent laws.

Since the judgment below forbids the sale of a copy of an unpatented article and orders an accounting for damages for such copying, it cannot stand.

Who won?

Compco Corp. prevailed in this case as the Supreme Court reversed the lower court's decision. The Court held that the actions taken against Compco for unfair competition were not permissible under federal patent laws, which allow for the copying of unpatented articles. The ruling emphasized the importance of federal law in maintaining free access to the public domain, thereby protecting Compco's right to sell its fixtures without being held liable for unfair competition.
