Apple Inc. lost another round in its decadelong legal battle over hundreds of millions of dollars in royalty claims by VirnetX Holding Corp. for patents used in virtual private networks including FaceTime.

A three-judge panel of the U.S. Court of Appeals for the Federal Circuit had already barred Apple from arguing the VirnetX patents are invalid, because such claims have failed in other cases. The full court on Monday refused to reconsider the November ruling.
