Kimble v. Marvel Entertainment, LLC, (Supreme Court, June 22, 2015)
Respondent Marvel Entertainment's corporate predecessor agreed to purchase petitioner Stephen Kimble's patent for a Spider-Man toy in exchange for a lump sum plus a 3% royalty on future sales. The agreement set no end date for royalties. As the patent neared the end of its statutory 20-year term, Marvel discovered Brulotte v. Thys Co., 379 U. S. 29, in which this Court held that a patentee cannot continue to receive royalties for sales made after his patent expires. Marvel then sought a declaratory judgment in federal district court confirming that it could stop paying Kimble royalties. The district court granted relief, and the Ninth Circuit affirmed. Kimble now asks this Court to overrule Brulotte.
Held: Stare decisis requires this Court to adhere to Brulotte.
