All Apple needed to do was contact them ahead of time and try to set up a deal with them regarding their patent. But they didn't, they went ahead and used their intellectual property without their consent, in the hopes that they wouldn't find out. Same as what happened with the Swiss Clock app. I agree that Virnetx are losers for trolling like this, but they had an idea that they patented, and Apple felt it was good enough to steal. So now Apple needs to pay up.
