USPTO assignment records recently made public have revealed the movement of more than 240 patent assets away from Wi-Fi One, LLC, a subsidiary of Inception Holdings, LLC. The original development work for the bulk of the transacted patents was conducted at either Panasonic or Sony, with the portfolio moving to Redwood Technologies, LLC, a subsidiary of a familiar patent monetization player that has undergone a bit of a reorganization in 2021.

Public records have identified Marconi as the source of at least some of the patents recently acquired by Acacia Research Corporation. The transacted portfolio, assigned in February to a newly created Acacia subsidiary, includes assets originating with Samsung as well as patents developed by Fusion-IO (which in 2014 was acquired by SanDisk for $1.1B).

The Patent Trial and Appeal Board (PTAB) saw activity in AIA reviews against a variety of familiar plaintiffs in September, including validity challenges brought in campaigns targeting wireless communications technology and mobile devices. Among the NPEs hit with petitions for inter partes review (IPR) in September were Intellectual Ventures LLC, which continues to pursue its existing litigation as it divests other parts of its portfolio; and entities controlled by Fortress Investment Group LLC and Uniloc Corporation Pty. Limited, both of which have kept up a barrage of new litigation asserting former Pendrell Corporation patents. Also in September, the PTAB instituted trial in IPRs against Quarterhill Inc. and an NPE related to PanOptis Equity Holdings LLC, and issued final decisions against private plaintiffs including General Patent Corporation.
