Acacia Sub Sues AMD

  • May 3, 2012

Advanced Processor Technologies (APT) [NPE], a subsidiary of Acacia Research, filed suit against Advanced Micro Devices (AMD), alleging that AMD’s microprocessors infringe three patents related to data processors with changing clock frequency, operating voltage, virtual memory, and lookaside buffers.  APT has filed eight prior suits since January 2011 against over a dozen defendants including Analog Devices, MarvellNvidia, Xilinx, and Zoran.  The patents-in-suit originated with Hitachi and were assigned to Renesas before being assigned to APT.  APT is one of several subsidiaries established in connection with the Renesas-Acacia strategic patent alliance formed in August 2010.  Two of the patents-in-suit were assigned to APT by Vachellia, another Acacia subsidiary, in August 2010 while the other patent was assigned to APT directly by Renesas in May 2011.  5/1, no judge yet assigned, Eastern District of Texas, 2:2012cv00264.
