Judge invalidates 13 Motorola patent claims against Microsoft

Google's Motorola branch isn't having much success lately in getting patent claims to stick against Microsoft. A few months after the company dropped some ITC claims, the judge in a Seattle contract lawsuit has granted Microsoft's motion to invalidate 13 of Motorola's claims across three standards-based patents, all of them linked to H.264 video coding. The individual claims aren't well-defined enough to hold, Judge James Robart says. The ruling takes most of the thunder out of components in the lawsuit that aren't directly related to the contract, and could lead to lighter penalties against Microsoft should Google and Motorola win -- not that Google has much sway when it's prevented from seeking bans over standards-based patents.
