Apple should agree to shut down all these services.
Then they should tell the impacted users to contact their Congresscritter and request reforms to the patent laws.
Why? The US Patent Office has already invalidated all four patents in suit. VirnetX is trying to hold up Apple using INVALID PATENTS merely because an ignorant jury in East Texas found against Apple in the trial because they could not understand the very technical issues in the suit. Apple was in the process of appealing the judgement when the USPTO invalidated the in suit patents completely so the process was never completed. VirnetX is trying to go back to the original well for MORE money and an injunction using invalidated patents. Absurdity upon absurdity.
The judge in the case, if he is at all interested in justice, should vacate the decision.
