Microsoft infringed Motorola Mobility's patents in making its popular Xbox gaming consoles, a judge for the International Trade Commission ruled on Monday.

Motorola Mobility, which is being acquired by Google, had filed related lawsuits against Microsoft in district courts in Wisconsin and Florida.

The full commission will review the judge's decision and issue a final ruling in August.

The case is at the International Trade Commission, No. 337-752.
