Kimble v. Marvel Enterprises involved a device that allowed its user to shoot “webs” a la Spider-Man. Kimble invented and obtained a patent for this web-shooting device and tried to sell or license that patent to Marvel Entertainment, the creator/owner of Spider-Man. Marvel declined, but ultimately came to market with its own “Web Blaster,” which similarly allowed its user to shoot webs a la Spider-Man. Kimble brought an action for patent infringement which was settled by Marvel purchasing Kimble’s patent for a lump sum plus a royalty on future sales of the “Web Blaster.” The agreement was open ended as there was no termination to the royalty payment.
Are Royalties Due After Patent Expires?
Kimble’s patent expired in 2010. Thereafter, Marvel brought a declaratory judgment action seeking a determination that it was no longer required to pay royalties on an expired patent. Marvel’s position was based on Brulotte v. Thys Co., 379 U.S. 29 (1964), where the Supreme Court held that a licensor is not entitled to patent royalties from a licensee after expiration of the licensed patent. The district court agreed with Marvel, finding no distinction between the fact that Brulotte involved a patent license agreement where the party receiving royalties retained ownership of the patent at issue and the Kimble/Marvel relationship where the party receiving royalties no longer owned the patent at issue. Thus, Brulotte controlled and no further royalties were required after expiration of the Kimble patent. The Ninth Circuit Court of Appeals affirmed reluctantly, agreeing that Brulotte was controlling precedent but felt that the decision was “counterintuitive.”
