Apple emerges victorious in decade-long patent battle with VirnetX.

Apple has won an appeal against patent licensing company VirnetX in a decade-long battle over patent infringement. The US Court of Appeals for the Federal Circuit upheld a decision by the US Patent and Trademark Office to invalidate patents related to FaceTime, VPN, and iMessage services. The patents were deemed invalid "in light of earlier publications that described the same inventions." The decision is expected to negate an initial $502m verdict against Apple, handing the tech giant a victory over VirnetX.
