Facts

Stephen Kimble, the patent holder, entered into an agreement with Marvel Entertainment to sell his patent for a Spider-Man toy, which included a 3% royalty on future sales. As the patent approached its expiration, Marvel discovered the precedent set by Brulotte v. Thys Co., which prohibited patent holders from collecting royalties after the patent term expired. Marvel sought a declaratory judgment to stop paying royalties after the patent expired, leading to a ruling in their favor from the district court and affirmation by the Ninth Circuit.

Issue

Whether the Supreme Court should overrule the precedent established in Brulotte v. Thys Co., which holds that a patent holder cannot charge royalties for the use of his invention after its patent term has expired.

The sole question presented here is whether we should overrule Brulotte.

Rule

A patent holder cannot charge royalties for the use of his invention after its patent term has expired, as established in Brulotte v. Thys Co., which interpreted the patent laws to prevent the extension of patent rights beyond their statutory term. The expiration of a patent transfers the unrestricted right to make or use the article to the public.

Analysis

The court applied the rule from Brulotte, emphasizing that allowing royalties post-expiration would conflict with the policy of ensuring public access to inventions once their patent terms end. The court noted that while the Brulotte rule may limit some business arrangements, it does not prevent parties from structuring alternative agreements that comply with the law. The court also highlighted the importance of stare decisis in maintaining legal stability and predictability.

The Brulotte rule may prevent some parties from entering into deals they desire, but parties can often find ways to achieve similar outcomes. For example, Brulotte leaves parties free to defer payments for pre-expiration use of a patent, tie royalties to non-patent rights, or make non-royalty-based business arrangements.

Conclusion

The Supreme Court affirmed the lower court's ruling, maintaining that a patent holder cannot charge royalties after the patent term has expired, thereby upholding the precedent set in Brulotte.

Held: Stare decisis requires this Court to adhere to Brulotte.

Who won?

Marvel Entertainment prevailed in this case as the court upheld the ruling that they could cease paying royalties to Kimble after the expiration of his patent. The court's decision reinforced the principle that patent rights are limited in duration and that once a patent expires, the rights associated with it also expire, allowing the public to freely use the invention without restriction.

Marvel must have been pleased to learn of it. Brulotte had read the patent laws to prevent a patentee from receiving royalties for sales made after his patent's expiration.
