New NPE Tactile Feedback Technology (TFT) filed suits against Samsung and ZTE, asserting four patents in litigation. Timothy Pryor, the founder of TFT, is the sole named inventor on all four patents-in-suit, which relate to a touch screen interface (7,973,773, 8,013,843, 8,068,100, 8,072,440). Defendants’ smartphone handsets and tablets are accused of infringement. Pryor incorporated TFT in 2012, but this campaign is the entity’s first litigation. TFT owns a dozen patents and patent applications, including the patents-in-suit. 10/9, Eastern District of Texas, 2:14cv00940, 2:14cv00943
