Federal Court of Appeals affirms ruling in Masimo, Apple patent dispute

After Masimo (MASI) sued Apple (AAPL) for infringing the ‘703 patent, Apple petitioned for inter partes review of claims 1-7, 9-18, and 20-24 of the ‘703 patent, the United States Court of Appeals for the Federal Circuit noted in a ruling posted to its site. The Patent Trial and Appeal Board construed the claimed “processing characteristics” as “determined from a signal received from one or more detectors configured to detect light.” J.A. 14. Based on this construction, the Board assessed Apple’s eight obviousness grounds, each of which addressed either or both of Diab and Amano. Ultimately, the Board concluded that Apple failed to show obviousness of the challenged claims. Apple appealed. The Court stated in a ruling posted today: “We have considered Apple’s remaining arguments and find them unpersuasive. Accordingly, the decision of the Board is affirmed.”
