Spherix’s new suit continues to assert patents previously owned by Nortel, but the specific patents-in-suit were not asserted in prior litigation. Eleven patents are asserted against Cisco related to networking devices as well as control and management of voice and data communications through those devices (5,970,125, 6,130,877, 6,222,848, 6,578,086, 6,697,325, 6,807,174, 7,385,998, 7,397,763, 7,664,123, 8,607,323, RE40,467). In the complaint Cisco’s networking products, including routers, switches, networking software, and VOIP products, are accused of infringing the asserted patents. The patents are part of the portfolio acquired from Nortel by Rockstar Bidco in July 2011 and later transferred to subsidiary Rockstar Consortium. In July 2013 Rockstar became a shareholder of Spherix and at the same time transferred an undisclosed number of patents to the entity, including those asserted against Cisco. One month later Spherix began asserting former Nortel patents acquired from Rockstar, suing VTech and Uniden in suits that asserted a group of up to five patents. The Spherix campaign is defined by its assertion of former Nortel patents related to network communication, although the same patents are not involved in each suit. 3/24, District of Delaware, 1:14cv00374
