Patent Troll IV Running Out Of Cash; Looking For $3 Billion

Of course, the Reuters article also highlights how many of the big tech companies who signed up early on are not at all interested in supporting IV any more. As we noted years ago, Nathan Myhrvold built IV with a sort of bait-and-switch pitch. He told everyone that he was building a "patent defense fund," which tech companies could share to avoid getting sued by others. It was only later that the companies realized they were enabling a new massive patent troll instead. And it seems that many are not happy.
