Last month’s review of notable patent assignments considered the movement of assets from Avaya to Dominion Harbor Enterprises, LLC; from Level 3 Communications to Sandpiper CDN, LLC; from Seiko Epson to IPValue’s 138 East LCD Advancements Ltd. and Lumitek Display Technology Ltd.; from Transaction Security to a “BioCrypt Access”; from Fortress Investment Group LLC’s KIP Prod P1 LP to Prodea Automation LLC; from EMM Patents Ltd. to Empire IP LLC; from Siemens and Abdelsalam Helal to Rokiot USA LLC; and from Proxicom Wireless, LLC to Secure Communication Technologies, LLC. While a couple of these entities again feature prominently, this month’s review extends well beyond them to cover the movement of patents away from other operating companies, as well as within several repeat monetization players.

Publicly available USPTO assignment records indicate that MIMIRIP LLC, an Ideahub, Inc. plaintiff, picked up a large portfolio of assets from SKhynix in early March of this year. MIMIRIP has now filed two Eastern District of Texas complaints against Micron Technology (2:24-cv-00405, 2:24-cv-00407), both under seal, as well as a complaint before the International Trade Commission (ITC) (337-TA-3751). Proposed respondents include Dell, HP Enterprise (HPE), HP, Kingston Technology, Lenovo, and Tesla, with infringement allegations—with respect to a dozen of those former SKhynix patents—targeting Micron-manufactured DRAM and NAND memory devices, as well as devices containing them, “such as laptops, tablets, servers, solid-state drives, self-driving automotive computers, and automotive media control units”.
