Rubber Tire Wheel Co. v. Goodyear Tire & Rubber Co.
Headline: Court limits immunity for component sellers and strikes down an injunction shielding a tire maker’s customers who assemble patented tires, allowing patent owners to sue independent assemblers who construct the patented combination.
Holding: The Court reversed the injunction, holding that a company’s prior victory asserting noninfringement does not bar patent owners from suing third parties who buy components and themselves make the patented tire combination.
- Allows patent holders to sue third parties who assemble patented products from bought components.
- Stops component sellers from claiming immunity to shield customers who make the patented device.
- Confirms buyers of completed patented products sold by a successful seller remain protected from suit.
Summary
Background
The dispute involved the owners of the Grant patent for a rubber-tired wheel and the Goodyear Tire and Rubber Company. Lower courts disagreed about whether the patented tire was new, and this Court had earlier held the Grant tire patent valid in a related case. Goodyear had won a prior suit, and after that judgment it asked a court to block the patent owners from suing Goodyear’s customers. One customer, a New York wheel shop owner named Doherty, had bought rubber and other parts and assembled a complete tire himself.
Reasoning
The core question was whether Goodyear’s earlier win gave it the right to stop the patent owners from suing others who bought Goodyear’s rubber and then made the patented tire. The Court relied on the earlier Kessler decision but said that decision only protects buyers of a completed article sold by a defendant who prevailed. Selling a raw part, like rubber, is different: when a buyer assembles those parts into the patented combination, they create a new product and can be sued. The Court therefore reversed the injunction that had blocked the patent owners from suing Doherty.
Real world impact
The ruling means companies that sell components cannot automatically claim a broad immunity that shields customers who take those components and build the patented device. At the same time, sellers of a completed patented product that was already adjudicated noninfringing remain able to have their buyers protected. The Court sent the case back with instructions to deny the requested injunction, leaving individual defenses between the shop owner and the patent owners available to be raised in court.
Dissents or concurrances
Justice Day disagreed with the majority’s outcome and stated he would have upheld the injunction under the Kessler principles, believing the suit against Doherty could properly be enjoined.
