Tierra Intelectual Borinquen (TIB) filed 11 separate suits against Acer (with Office Max), Asustek, HTC, Kyocera, Lenovo, LG, Pantech, Samsung, Sony, Toshiba, and ZTE alleging that the defendants’ tablets and mobile phones that allows users to select a mode to unlock the product — such as through face recognition, password, pin, pattern, or slide mode —  infringe two patents related to a computer-implemented method for creating a signature for subsequent authentication (7,350,078 and 7,725,725). These are the first patent infringement suits initiated by TIB. The patents-in-suit were invented by Gary Odom and briefly assigned to FTE Exchange before being assigned to TIB in December 2012. RPX reviewed the patents-in-suit as an open market opportunity (IP Investments – OMA) in July 2012. 1/22, Eastern District of Texas, 2:13cv00037; 2:13cv00038; 2:13cv00039; 2:13cv00040; 2:13cv00041; 2:13cv00043; 2:13cv00044; 2:13cv00045; 2:13cv00046; 2:13cv00047.
