What to do if the patent is asserted? Hunt down the parties responsible and butcher them like cattle. I don't know anything about hiring assassins, but surely compared to the hundreds of millions (billions?) paid out in bullshit patent lawsuit settlements, buying the death of the head of every known patent troll company (and their lawyers) would be a drop in the bucket, and probably a net benefit to society aside. Imagine if RIM were run by the mafia - they'd have taken care of this years ago, and anyone left would be too terrified to troll patents today!
Justice, glorious justice.
