Back in 2013, Apple had to redesign FaceTime to use server relayed connections instead of peer-to-peer to circumvent VirnetX's patent(s) [1]. I wonder if, after this verdict, they will (and are allowed to) undo this change and start doing peer-to-peer again; Apple will probably have invested quite a lot in their (cloud) infrastructure to support these server relayed connections.
