Silicon Graphics Patents Asserted against Apple, HTC, LG, RIM, Samsung, and Sony

  • November 29, 2011

Graphics Properties Holdings (GPH) [NPE] filed six separate suits against Apple, HTC, LG, RIM, Samsung, and Sony, alleging that the defendants’ devices infringe three patents related to displays. The patents were at one time held by Silicon Graphics and were subsequently assigned to Morgan Stanley in 2007.  According to the complaints, “GPH was formerly named Silicon Graphics, Inc. As Silicon Graphics, GPH developed technology and intellectual property used in the graphics, computer processing, and display segments. GPH is owned by private investment funds and other institutional investors, following the bankruptcy of Silicon Graphics.”  On November 22, 2011, GPH filed a complaint with the ITC against the same six companies.  GPH has filed two prior suits (involving different patents) since November 2010 against over ten defendants including Acer, Dell, HP, Lenovo, Nintendo, Sony, and Toshiba, and was subject to one action for declaratory judgment brought by Apple in November 2011.  RPX reviewed the Silicon Graphics portfolio as an open market opportunity in 2010. 11/23, District of Delaware, 1:2011cv01161; 1:2011cv01162; 1:2011cv01163; 1:2011cv01164; 1:2011cv01165; 1:2011cv01166.
