A legal battle between Apple and VirnetX that dates back nine years has seen a new development today, with a $503 million judgment from 2018 against Apple for patent infringement vacated by an appeals court and the case sent back to a lower court for reconsideration, reports Reuters.
The result is a mixed one for Apple at this point, with the appeals court finding only a partial reversal in affirming infringement by Apple on two counts and reversing on two other counts. The appeals court is sending the case back to district court to determine whether revised damages against Apple can be calculated or if a new damages trial will have to be held.
The case in question is just one of two involving Apple and VirnetX over communications security patents related to VPN, iMessage, and FaceTime. Apple is currently on the hook for $440 million in the other case, but appeals remain in progress.
