A judge for the U.S. International Trade Commission has ruled that Microsoft infringed Motorola Mobility’s patents in making its popular Xbox gaming consoles. ITC Judge David Shaw said that Microsoft infringed four patents and did not infringe on a fifth in the complaint.
The full commission will review the judge’s decision and issue a final ruling in August. The patents in the complaint are for technology like wireless connections for the Xbox to the Internet and video compression to speed transmission.
Motorola Mobility has demanded that the infringing devices should be barred from importation into the United States. Motorola Mobility, which is being acquired by Google Inc, had filed related lawsuits against Microsoft in district courts in Wisconsin and Florida.
The trade commission complaint is related to the larger smartphone patent war between Apple, Microsoft and the mobile phone makers who use Google’s Android software. Motorola Mobility is among them.
Tech companies have spent billions of dollars to buy patent portfolios that they can use defensively or offensively, and still more money litigating in the United States and Europe.
Microsoft has released a statement saying that it would press on with the case. Motorola Mobility said it was pleased with the decision.
