I said "bunch of other ex-Microsofties"
Seriously, Allen sued everybody and their dog, and left out Microsoft. He is Microsoft proxy, attacking Microsoft's competitors. It is that obvious.
Nathan Myhrvold and Bill Gates own world's largest patent trolling company called Intellectual Ventures. http://www.intellectualventures.com/Home.aspx
They buy patents on auction from failed companies and then give to their sub-companies to sue (they don't sue by themselves, it would be smoking gun). I suspect that is how Allan got those patents.
Every Microsoft competitor is under threat when Microsoft sends it's trolls on a Jihad.
