Far North Patents, LLC has added four Western District of Texas cases—against ADVA Optical Networking (6:20-cv-00218), Analog Devices (6:20-cv-00219), Microchip (6:20-cv-00221), and ZTE (6:20-cv-00222)—to the eight that it filed in the Eastern District of Texas this past December. A dozen networking patents, received from Intellectual Ventures LLC (IV) in December 2018, are at issue in the campaign, with each of the new complaints asserting the same five. ADVA, Analog Devices, Microchip, and ZTE have been accused of infringement through the provision of networking hardware and systems that feature “advanced quality of service [QoS] capabilities”.
