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”.
In late October, RPXreported the recordation of the December 2018 assignment of over 50 US patents, together with multiple foreign counterparts, out of Intellectual Ventures LLC (IV) to Far North Patents, LLC. Over the holidays, the recipient began litigating them, suing Broadcom (CA Technologies) (4:19-cv-00939), IBM (4:19-cv-00940), Marvell (4:19-cv-00941), Mitel Networks (4:19-cv-00942), NEC (4:19-cv-00943), NXP Semiconductors (4:19-cv-00944), Ribbon Communications (4:19-cv-00945), and TI (4:19-cv-00946) in the Eastern District of Texas. The NPE accuses Mitel, NEC, and Ribbon each of infringing the same ten patents from the transferred IV assets, with subsets of those patents asserted against the remaining defendants; Far North’s infringement allegations target networking equipment and unified/integrated network management systems.
