On Monday, the US Supreme Court vacated a 2014 Federal Circuit decision that had revived Azure Networks, LLC’s infringement claims against Marvell and several other semiconductor companies. The high court remanded the case back to the Federal Circuit for reconsideration under its more recent decision in Teva v. Sandoz. A key issue in the four-year legal battle with the NPE has been the construction of the term “MAC address” in the claims of 7,756,129, a personal area network patent that Azure has asserted in litigation against more than 20 companies.
