Sprint, Clearwire Sued Over WiMax Patents

Sprint Nextel (NYSE: S) and Clearwire’s goal to deploy a nationwide WiMax network may have hit a bump in the road as they face a patent lawsuit from base station vendor Adaptix. In a filing this month with the U.S. District Court for the Eastern District of Texas, Adaptix said Sprint and Clearwire are infringing upon six patents related to WiMax technology. The company said it wants unspecified damages, payment of legal fees, as well as an injunction that would stop Sprint and Clearwire from infringing on the patents.
