Longhorn IP Opens Up Second Litigation Campaign over Semiconductor Fabrication Patents

Katana Silicon Technologies LLC, an affiliate of Longhorn IP LLC, has filed its first litigation, accusing Samsung (6:19-cv-00344) of infringing two of the nine patents that the NPE acquired from Sharp last summer. The patents generally relate to transistor fabrication, with infringement allegations focused on Samsung’s 2D planar technologies, “such as its 20nm planar technology”; its bulk FinFET technologies, “such as its 14nm, 11nm, 10nm, 8nm, and 7nm bulk FinFET technologies, which include but are not limited to the 14LPU, 11LPP 10LPE, 10LPP, 10LPU, 8LPP, and 7LPP nodes”; and certain processors and consumer products that contain either of them.
