products, including the valve, to Petro Pumps, Inc., which uses the valve to make oil
pumps. Under the terms of the license, Petro agrees to pay royalties on O.K.’s

royalties on the sales of its pumps. Petro wants to challenge the validity of O.K.’s
patent. According to the majority in MedImmune, Inc., v. Genentech, Inc. case, a patent
