This past week, the USPTO made public assignment records confirming the acquisition of patents by two NPEs that have recently filed litigation. According to those records, Sovereign Peak Ventures, LLC (SPV), an affiliate of Texas monetization firm Dominion Harbor Enterprises LLC, received over 500 assets from Panasonic in October 2018. SPV has launched a first litigation campaign from those assets, asserting three LED lighting patents in cases filed in December 2018 and earlier this month. The recently released USPTO records also identify roughly 65 US patents assigned from Entropic Communications, a subsidiary of MaxLinear, to Dynamic Data Technologies, LLC (DDT). Those patents are part of a larger acquisition effort by DDT, which in October began an international litigation campaign asserting a subset of the acquired portfolio.
