'Microsoft Xbox didn't violate Google patent'

Microsoft Corp won a round in a complex patent war in the US on Thursday when the International Trade Commission (ITC) said the company's popular Xbox entertainment system did not violate a patent owned by Google subsidiary Motorola Mobility.

If the ITC had found that Microsoft infringed, it could have barred the Xbox from being imported into the US. The fight over the Xbox is related to a larger smartphone patent war between Apple, Microsoft and the mobile phone makers who use Google's Android software.
