Facts

The case involves an appeal from the Patent Office's decision to deny the registration of a trademark for the configuration of the crown portion of a safety helmet. The applicant claimed that the design, which featured ribs and corrugations, was distinctive and had been used continuously in commerce since 1939. However, the board found that the design was primarily functional and that the applicant had allowed a competitor to sell hats with the same design, undermining its claim to exclusivity.

Issue

Whether the configuration of the crown portion of a safety helmet can be registered as a trademark under the Lanham Act.

Whether the configuration of the crown portion of a safety helmet can be registered as a trademark under the Lanham Act.

Rule

Analysis

The court analyzed the functionality of the rib design, noting that it served a structural purpose in reinforcing the helmet and deflecting falling objects. The applicant's own advertising emphasized these functional aspects rather than any trademark significance. Additionally, the sale of identical designs by competitors and the applicant's permissiveness in allowing another company to sell hats with the same design further indicated that the design had not acquired distinctiveness as a trademark.

Denial of application to register as trademark the configuration of crown portion of safety helmet or hat, which was done-shaped, and which had alleged distinctive feature consisting of ribs or corrugations extending outwardly of crown and arranged in particular manner, was proper, in view of structural functionality of the rib design, and applicant's permissiveness in letting another manufacturer sell hats with identical design.

Conclusion

The court affirmed the Patent Office's decision, concluding that the rib design was not a trademark due to its functional nature and lack of distinctiveness.

Registration was therefore properly refused and the decision of the board is affirmed.

Who won?

The Patent Office prevailed in this case as the court upheld its decision to deny the trademark application. The court reasoned that the design was functional and had not acquired distinctiveness, as evidenced by the applicant's own admissions and the competitive landscape where similar designs were used by others without trademark claims.
