The lawsuit was filed in the United States District Court for the Western District of Washington earlier today.

Microsoft says that their action today “merely seeks to ensure respect for our intellectual property rights infringed by Android devices.” They go on to add that, recent patent lawsuits filed by Apple and Oracle suggest that the Redmond-based company is not alone in their desires.
