Commstech LLC has added a Central District of California case against Unizyx Holding (ZyXEL) (8:20-cv-00939) to the litigation campaign that the NPE began over roughly one year ago. The complaint again targets the provision of networking switches, including the Zyxel XGS3600 series switches, this time with just one of the six patents-in-campaign, received from Harris Corporation. Each of the cases filed has been short-lived, with the only other active suit filed against Fortinet in the Western District of Texas in mid-April.
