Apple wins U.S. appeal over patents in $502 million VirnetX verdict

Apple Inc persuaded a U.S. appeals court on Thursday to uphold a patent tribunal’s ruling that could imperil a $502 million verdict for patent licensing company VirnetX Inc in the companies’ long-running fight over privacy-software technology.

The U.S. Court of Appeals for the Federal Circuit affirmed a decision from the U.S. Patent and Trademark Office that invalidated the two patents VirnetX had accused Apple of infringing.
