AIP Campaign Shifts Focus to Carriers

  • April 24, 2014

Telecommunications carriers are the latest targets of the AIP campaign. AIP filed suits against AT&T, Sprint, T-Mobile, and Verizon accusing the carriers’ click-to-call and simultaneous ring service features of infringement. The cases involve a total of five patents related to integrating voice and data network technologies (6,078,654, 6,188,756, 6,496,579, 7,269,247, 7,724,879). All five patents are asserted against AT&T, Sprint and Verizon. The case against wireless carrier T-Mobile asserts only the ’879 patent. In 2012, AIP sued cable providers Cablevision, Cox, Charter and Time Warner Cable. In January 2014, those cases were stayed pending inter partes review of the ’879 patent. The AIP patents originated with carrier networking provider Arbinet and were assigned to AIP in 2011, around the time Arbinet was acquired by Primus Telecommunications. RPX reviewed the patents-in-suit as part of an open market opportunity (Arbinet-Acq) in August 2009. 4/23, District of Delaware, 1:14cv00513, 1:14cv00514, 1:14cv00515, 1:14cv00516
