After suing Motorola over smartphone patents, Microsoft now sued the company again on Nov'9th -- this time, the complaint is focused on wireless and video coding patents used by the Xbox team. Here's Microsoft's statement:
"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 Institute of Electrical and Electronics Engineers (IEEE) and 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."
Patent expert Florian Mueller has more details on the latest patent Microsoft vs. Motorola. He notes the "patents in question also pertain to smartphones, not just Xbox."
