Apple prevails in U.S. appeal against VirnetX's $502 million patent verdict.
Apple has won an appeal in a US court that upheld a patent tribunal's ruling invalidating two patents that VirnetX had accused Apple of infringing. The decision could jeopardize a $502m verdict for patent licensing company VirnetX in its long-running fight with Apple over privacy-software technology. VirnetX is considering seeking a rehearing or appealing to the US Supreme Court. The two companies have been in a 13-year court battle that has included several trials and appeals.
