AIM IP [NPE] filed suit against Yealink Network Technology, alleging that the defendant’s VoIP products that “support or utilize a system for coding and/or decoding feature vectors of a signal according to the G.729B standard” infringes a patent related to signal compression.  AIM IP has filed eight prior suits since April 2011 against Alitgen Communications, Avaya, Cisco, Dialogic, D-Link, Gigaset Communications, Grandstream Networks, Hellosoft, HP, Mitel Networks, Network Equipment Technologies, Polycom, Skype, Sonus Networks, UT Starcom and ZyXEL Communications involving the same patent.  The patent-in-suit originated with Rockwell International Corporation, which assigned the patent to its semiconductor division Conexant Systems in December 1998.  In January 1999, Conexant Systems was spun-out and became an independent semiconductor business. In October 2010, Conexant Systems assigned the patent-in-suit to AIM IP.  RPX reviewed the patent-in-suit in the open market in January 2011 (AIM 1 – Acq).  6/8, Central District of California, Magistrate Judge Jean P.
