Is it whatsoever possible for Google to get a group of companies together and counter-sue Oracle and Microsoft en masse? I mean Motorola isn't without a strong patent portfolio, and I doubt they'd be the only ones on board? Forgive me if its a naive thought, but it seems like we might just be seeing the beginning of Google patent issues (and I obviously treat the MS/Motorola thing as a Google patent issue). Is the risk of pissing off MS/Oracle too great (not for Google, but for potential allies?) Why haven't they gone nuclear yet?! I wanna see that bad.
