In the first half of November 2015, RPX saw six patent transfers to NPEs recorded by the USPTO. Two of those recently recorded transactions involve patents that have been previously asserted in litigation against operating companies.

Hilltop Technology filed suit against Apple asserting a patent related to capacitive touch screens (7,864,503). The Hilltop patent, previously marketed as “SensePad,” has a 2007 priority date. Hilltop launched its campaign in September 2013 against display suppliers AU Optronics, TPK, and Wintek. Those cases are currently ongoing. RPX reviewed the patent in June 2013. 1/29, Eastern District of Texas, 2:14cv00050
