Liberty Patents LLC v. Texas Instruments, Inc.

Last month, Liberty Patents LLC launched a second litigation campaign with suits against Analog Devices, Lattice Semiconductor, and Texas Instruments (TI) over clock generators. The plaintiff has followed those January complaints with another suit against TI (2:21-cv-00050), this one back in its first litigation campaign. The plaintiff asserts four power management patents, three of which are new to litigation, with infringement allegations targeting the provision of the TDA2X System-on-Chip devices. At issue is the incorporation of certain ARM-branded processors and support of the Adaptive Body Bias (ABB) technique. To date, Liberty Patents has asserted eight patents—each received in a portfolio of over 130 assets from Intellectual Ventures LLC (IV) in December 2019—against a total of over 20 defendants across its two litigation campaigns: the first, launched in September 2020; and the second, in January 2021.
