In late October, RPX reported 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.
