Patent Infringement Lawsuit Filed Against Red Hat & Novell Linux

IP Innovation LLC has just filed a patent infringement claim against Red Hat and Novell. It was filed October 9, case no. 2:2007cv00447, IP Innovation, LLC et al v. Red Hat Inc. et al, in Texas. Where else? The patent troll magnet state.
The first ever patent infringement litigation involving Linux. Here's the patent, for those who can look at it without risk. If in doubt, don't. Here's the complaint [PDF].
And now let's play, where's Microsoft? You know, like where's Waldo? Betcha he's in the tree's leaves somewhere if we look close enough. We had our first hint when Steve Ballmer said in his speech the other day that he figured other folks besides Microsoft would want Red Hat and FOSS to pay them for their patents. Remember? Is he a prophet or merely well informed? Or is there more to this? When I lay out all the research, you can decide.
