Microsoft filed an action today in the U.S. District Court for the Western District of Washington against Motorola, Inc. for breach of Motorola's contractual commitments to the Institute of Electrical and Electronics Engineers (IEEE) and the International Telecommunications Union (ITU) to license identified patents related to wireless and video coding technologies under reasonable and non-discriminatory terms and conditions. Those commitments are designed to benefit all parties that rely upon these standards, and Microsoft has been harmed by Motorola's failure to honor them in recent demand letters seeking royalties from Microsoft.
