This week’s look at US patent assignments recently made public by the USPTO considers the movement of a networking portfolio to a New Mexico plaintiff that has already filed suit; the transfer of a portfolio from a shuttered Colorado-based software company that used to operate in the SSD space to a Delaware entity formed by its last CEO; and suggestions in a recent denial of a motion to compel from Eastern District of Texas Judge Rodney Gilstrap that the conduit of a pair of portfolios divested from an operating company has retained a financial interest in the outcome of subsequent litigation over one of them.

In separate Eastern District of Texas complaints, xMatrix LLC has accused ASUSTOR (2:25-cv-00078), QNAP Systems (2:25-cv-00076), and Synology (2:25-cv-00077) of infringing two networking device patents. The New Mexico plaintiff pleads ownership of the patents, absent a transfer in public assignment records from Prodea Automation LLC, a New York entity that merged in December 2023 with KIP Prod P1 LP, itself tied to Fortress Investment Group LLC.
