Graphics Properties Holdings (GPH) [NPE] filed six separate suits against Apple, HTC, LG, RIM, Samsung, and Sony, alleging that the defendants’ consumer electronics and mobile phones infringe a patent related to electronic displays.  According to the complaint, “GPH was formerly named Silicon Graphics.  As Silicon Graphics, GPH developed technology and intellectual property used in the graphics, computer processing, and display segments.  Since the bankruptcy of Silicon Graphics, GPH has been owned by private investment funds and other institutional investors.”  GPH has filed over a dozen prior suits since November 2010 against defendants including Acer, ASUS, Dell, HP, Lenovo, Motorola Mobility, Nintendo, Panasonic, Sharp, Sony, Toshiba, and Vizio and was subject to one action for declaratory judgment brought by Apple in November 2011.  In 2011, GPH filed six separate suits and an ITC investigation against the same six defendants in this suit, but over three different patents.  RPX reviewed the Silicon Graphics portfolio as an open market opportunity in 2010.  3/27, District of Delaware, 1:2012cv00385; 1:2012cv00386; 1:2012cv00387; 1:2012cv00388; 1:2012cv00389; 1:2012cv00390.
