Google

The patent arms race continues as Google purchased 1,023 patents from IBM in August. The patents run the gamut from hardware to software. As SEO by the Sea points out, some relate to Java, others to networking, and others to search. It's tough to tell whether we're looking at an offensive or defensive purchase here (and that all depends on whom might have already licensed those patents, or if they'll need to in the future). And, so, the game goes on.
