Facebook isn’t going to meekly stand by as Yahoo wages a patent war against it. In a move that clearly shows Facebook’s intentions, the company has purchased 750 patents from IBM in an effort to dissuade Yahoo from pursuing legal action. Of course, while these patents could end up being used for any number of cases by Facebook, it is likely that Facebook will use them as a tool to fight Yahoo. In the end, though, Facebook and Yahoo will settle. Everyone settles.
