RPX’s last look at notable patent assignments considered the movement of assets to Ueran Technology LLC from Huawei; to AX Wireless, LLC from SOLiD; to VideoLabs, Inc. from DCX US Agility Platform LLC, a subsidiary of DXC Technology; to Flash Uplink LLC from its publicly traded parent Quest Patent Research Corporation (QPRC); to various entities from Ascend Innovation Management, LLC entities; and to Nera Innovations Limited from multiple entities associated with Atlantic IP Services. It is time for a review of additional notable transfers recorded since then.

2021 saw former Honeywell, Panasonic, Sony, and TCL Technology Group portfolios sail into Dominion Harbor Enterprises, LLC—as well as hundreds of Seiko Epson patents, according to data recently made public by the USPTO. Meanwhile, the Texas-based monetization firm has filed a handful of new cases so far this month, all asserting former operating company patents.

Among acquisitions earlier this year involving patents originating with Panasonic, Sony, or TCL Technology Group, Dominion Harbor Enterprises, LLC also received a portfolio from Honeywell, according to USPTO data. That string of 2021 patent transfers appears to have coincided with somewhat of a reorganization for Dominion, with public records also indicating that the firm received a capital injection at some point this year.
