GPH Sues Motorola Mobility with Patents from Silicon Graphics

  • February 1, 2012

Graphics Properties Holdings (GPH) [NPE] filed suit against Motorola Mobility, alleging that Motorola Mobility’s smartphones and tablets infringe three patents related to electronic displays.  The patents-in-suit originated with Silicon Graphics and were assigned to GPH in June 2009.  According to the complaint, “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.”  In November 2011, GPH filed suit against Apple, HTC, LG, RIM, Samsung, and Sony and filed a complaint with the ITC against the same six companies.  GPH has filed two other 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.  1/30, District of Delaware, 1:2012cv00108.
