On May 13, 2016, the United States Court of Appeals for the Federal Circuit summarily affirmed the PTAB’s ruling that all challenged claims of U.S. Patent No. 6,738,799, are unpatentable under Rule 36, effectively ending the assertion of those claims against multiple parties. The patent owner is a subsidiary of Marathon Patent Group, Inc. and has repeatedly asserted the patent against multiple operating companies. See Clouding Corp. v. Unified Patents Inc., No. 15-1799 (Fed. Cir. May 13, 2016) (Rule 36 Affirmance).
