Parity Networks LLC has doubled the number of active suits in the campaign that it began back in November 2016, adding Central District of California cases against EdgeCore (8:20-cv-00699), Moxa (8:20-cv-00698), and Unizyx (ZyXEL) (8:20-cv-00697). Those suits join ongoing litigation in cases brought earlier this year against Aviat Networks (6:20-cv-00057), D-Link (6:20-cv-00093), and Mellanox Technologies (6:20-cv-00051) in the Western District of Texas. The asserted patents, asserted in overlapping sets, broadly concern various aspects of network traffic management, with infringement allegations aimed at the defendants’ switch products.
