Microsoft today filed a lawsuit against U.S. Customs and Border Protection and the U.S. Department of Homeland Security seeking a court order forcing Customs to enforce an import ban against certain Motorola smartphones.

The suit, filed in the U.S. District Court of Washington D.C., accuses the U.S. agencies of “arbitrary refusal to enforce an order” of the U.S. International Trade Commission (ITC).

The U.S. International Trade Commission has decided to make final a judge’s preliminary ruling that Microsoft’s Xbox console does not infringe on a Motorola patent.

The decision brings to a close a case in which Motorola — now owned by Google — had sought an import ban into the U.S. of all Xbox consoles, claiming that certain technologies used in the Xbox violate Motorola’s patents. (Xbox console are manufactured mainly in China.)
