A May assignment from Sharp to a newly formed affiliate of Longhorn IP LLC was recorded with the USPTO this month, closely following the NPE’s acquisition in early May of a portfolio from Intellectual Ventures LLC (IV). Longhorn IP has launched one campaign in the US to date, suing Micron, Nanya, Renesas, SanDisk, SMIC, Toshiba, UMC, and Western Digital over patents originating with AMD. It also has active litigation in Asia.
