I'm hoping this is a bid for Motorola's patents so that Google can legitimately defend itself against Apple, Microsoft, and all the others conspiring against them. Still, I'm surprised they didn't go after HTC. Maybe Motorola was actually selling, but I thought HTC was a bigger partner (they have more Android phones). Still, Apple will probably fight this on "anti-trust" grounds, even though Apple makes their own phones and phone OS, they'll find a problem with Google doing the same thing.

Licensing one patent does NOT protect you when someone sues you for violating a different patent. With patent wars, when one party sues the other for infringement, the defendant usually sues back for infringement of a different patent. Licensing a patent provides protection only from the patent you are licensing. So Google could have licensed every last Motorola patent, that wouldn't protect them when Apple comes suing.
