AT&T and Southwestern Bell Telephone filed an action for declaratory judgment against InterAD Technologies [NPE], seeking declaration that their U-Verse consoles and remote controls, U-Verse On  Demand,  U-Verse  Pay-Per-View,  Interactive  Television Advertising and Enhanced  Overlay Advertising products do not infringe a patent related to video-on-demand services.  InterAD filed one prior suit in September 2011 against 18 defendants including AT&T, Comcast, DISH Network, DirecTV, Time Warner, and Verizon.  On January 5, 2012, InterAD voluntarily dismissed AT&T from this prior suit.  However, according to the complaint, InterAD expressed no reason for the dismissal and did not state that it no longer asserts infringement, therefore AT&T had reasonable information to infer that InterAD would sue the defendants individually to remain consistent with the America Invents Act.  The patent-in-suit was assigned to Trento Enterprises before being assigned to InterAD in July 2011.  RPX recently resolved the InterAD litigation, obtaining sublicense rights for clients.  1/5, Northern District of Texas, 3:2012cv00044.
