Last week Cisco became the first target of Bockstar Technologies, a subsidiary of RockstarConsortium. The case asserts five patents related to data networking, all of which were part of the Nortel portfolio assigned to RockstarBidco in 2011 (5,732,080; 6,069,895; 6,233,245; 6,636,508; 6,684,241; 6,778,653). The Bockstar complaint accuses Cisco switches of infringement. A corporate disclosure statement notes that Apple, BlackBerry, Ericsson, and Microsoft indirectly own more than 10% of Bockstar.

Other litigation campaigns were filed by Rockstar Consortium itself and subsidiary Constellation Technologies. 12/11, District of Delaware, 1:13cv02020
