Google’s Motorola Mobility division was dealt a serious blow in its ongoing legal battle with Microsoft over patents after a judge ruled that 13 of the patent claims it had asserted against the Windows and Xbox maker were not valid.
On Thursday in Seattle, U.S. District Judge James Robart issued an order invalidating 13 claims tied to three Motorola patents against Microsoft. The three patents include technology related to digital video encoding and decoding. While Robart ruled that some of the company's claims were legitimate, he also noted that 13 were not specific enough to be used in this case.
Judge Robart granted Microsoft’s motion for partial summary judgment, and threw out the 13 claims.
