On July 30, Unified Patents (Unified) filed an inter-partes review (IPR) against patent owner Broadband iTV in order to protect content delivery technologies from NPE activity. Broadband iTV claims its patents cover video-on-demand systems and on April 9, 2014, Broadband iTV asserted U.S. Pat. No. 5,648,824 ('824 patent) in Hawaii District Court. Upon review the asserted patent, Unified uncovered prior art that it believes invalidates the '824 patent. Unified's IPR challenges the validity of claims 1-4 and 7-11 of Broadband iTV's '824 patent. A copy of the filing can be found below.
