The Federal Circuit has affirmed a Patent Trial and Appeal Board (PTAB) finding that two patents held by VirnetX Inc. are unpatentable. A 2020 verdict from an Eastern District of Texas jury had awarded VirnetX $502M for infringement of those patents by Apple, but, per the appeals court, “Now that we have affirmed the Board’s finding of unpatentability, VirnetX has lost its cause of action, and its dispute with Apple is moot”.
