To begin with, Apple tells TechCrunch that it plans to appeal the final judgment. And it's no small matter that the USPTO has already invalidated all of VirnetX's patents. That doesn't stop the ongoing case, but the invalidation kicks in the moment all appeals have been exhausted. If Apple has better luck in court, VirnetX won't get a second shot -- and it can't wield those patents in new lawsuits regardless of what happens with Apple.

The judgment could still raise concerns for companies affected by other VirnetX-held patents, as it might set a higher bar for payouts in future cases. Microsoft 'only' had to pay $200 million, for example. However, VirnetX may have more trouble winning lawsuits going forward. A Supreme Court ruling in May forced companies to sue in places where they're either based or do a large chunk of their business, preventing companies from cherry-picking court districts that tend to favor trolls (such as the Eastern District of Texas). While this doesn't rule out future VirnetX victories, the firm will likely face a slower legal process and courts that aren't quite so receptive to its demands.
