NetSoc, LLC appeals the United States District Court for the Southern District of New York’s dismissal of certain patent-infringement allegations against Oath Inc. The dis- trict court held that NetSoc was collaterally estopped from asserting infringement of certain claims of U.S. Patent No. 9,218,591 following a decision by the United States District Court for the Northern District of Texas holding claims in related U.S. Patent No. 9,978,107 patent ineligi- ble under 35 U.S.C. § 101.
