We know patents are important to Facebook. The company recently spent $550 million on a bundle of AOL patents, via Microsoft. And the social network bought another 750 patents from IBM this year, all part of an aggressive strategy to build up a portfolio that earlier this year included only 56 patents, with 503 filed and pending. Part of its effort to stock up on patents might be motivated by the fact that Yahoo in March sued Facebook for patent infringement, although the two companies settled that dispute earlier in July.
