In 2011, a consortium formed from Microsoft, Apple, Sony, BlackBerry, and others spent $4.5 billion acquiring Nortel's patent portfolio, which contained a great deal of ammunition that could be used against Android. That threat has now been reduced. Today, 4,000 of the patents were purchased by a corporation called RPX, which has licensing agreements from Google, Cisco, and dozens more companies. [RPX is] a company that collects a bunch of patents with the goal of using those patents for member companies for defensive purposes. Even though RPX has generally been "good," the business model basically lives because of patent trolling. Its very existence is because of all the patent trolling and abuse out there. In this case, though, it's making sure that basically anyone can license these patents under FRAND (fair and reasonable, non-discriminatory) rates. The price being paid is approximately $900 million. While that article points out that this is considerably less than the $4.5 billion Microsoft and Apple paid originally, again, this is only 4,000 of the 6,000 patents, and you have to assume the 2,000 the other companies kept were the really valuable patents. In short, this is basically Google and Cisco (with some help from a few others) licensing these patents to stop the majority of the lawsuits -- while also making sure that others can pay in as well should they feel threatened. Of course, Microsoft, Apple and the others still have control over the really good patents they kept for themselves, rather than give to Rockstar. And the whole thing does nothing for innovation other than shift around some money.
