The U.S. Supreme Court has declined to hear Nike’s appeal of a decision by the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office that one of its Flyknit patents, which covers a process for knitting footwear tops, is invalid. Adidas had asked the board to invalidate the patent as part of its long-running dispute over Flyknit and Primeknit technologies. Nike’s arguments had previously been rejected by the U.S. Court of Appeals for the Federal Circuit, which has jurisdiction over appeals in patent cases, and the Supreme Court was asked to decide whether the board had acted improperly.
