Sprint and the newly-reconstituted Clearwire have faced many hurdles trying to get a nationwide WiMax mobile broadband network developed and deployed—not the least of which has been where to find the cash to roll out a nationwide network and stay ahead of LTE technology that will begin rolling out once analog television is shut off. Now, the companies face another obstacle from WiMax base station vendor Adaptix, which had filed suit in the patent holder-friendly Eastern District of Texas claiming the companies collectively infringe on six of its WiMax patents. Adaptix is seeking damages, legal fees, and an injunction to prevent Sprint and Clearwire from infringing on the patents while the case is underway.
