American Radio filed four separate suits against Broadcom, Cisco, Intel, and Qualcomm. The complaints allege that the defendants’ Wi-Fi receivers and transceivers, Bluetooth receivers and transceivers, cable TV receivers, tuners, and demodulators infringe one or two patents related to radio signal reconstruction using a signal processor. American Radio filed four prior suits in July 2012 against the same four defendants, asserting additional patents. Robert Hotto is the named inventor on the patents-in-suit, which were assigned to American Radio in December 2009. Hotto is a co-inventor on the widely asserted Klausner visual voicemail patents, and he and Judah Klausner were classmates at NYU. RPX reviewed the Hotto patent portfolio as an open market opportunity (Hotto) in October 2009. 10/3, Central District of California, assigned to Magistrate Judge Patrick J.
