In late March, Hydro Net LLC, an IP Edge LLC plaintiff, whipped off another round in one of its litigation campaigns over assets from the 30-patent portfolio that the NPE picked up from Linex Technologies, Inc. in September 2018. The latest defendants are Barracuda Networks (1:21-cv-00478), BlackBerry (1:21-cv-02773), Hon Hai Precision Industry (Sharp) (1:21-cv-02780), KVH Industries (1:21-cv-00480), and Yulong Computer (Coolpad Technologies) (1:21-cv-00481), each accused of infringement through the provision of devices (e.g., firewalls, smartphones, and cellular base stations) that support LTE-FDD cellular networking and wireless tethering capabilities (Coolpad) or certain Wi-Fi protocols (802.11a/b/g/n/ac for Barracuda and 802.11b/g/n for BlackBerry, KVH, and Sharp).
This past April Zyrcuits IP LLC, an entity affiliated with monetization firm IP Edge LLC, picked up a portfolio of 30 US patents, generally related to spread-spectrum wireless data transmission, from NPE Linex Technologies, Inc. In the months since then, that portfolio has given rise to four litigation campaigns: the first by Zyrcuits IP itself (at the end of August), the second by Aperture Net LLC (at the end of September), and two more, by Hydro Net LLC and by Stormborn Technologies LLC, respectively (at the end of October). On October 24, a subset of those former Linex patents were transferred from Zyrcuits IP to new IP Edge entity Pinnacle Licensing LLC, raising the possibility that the end of November might bring yet more litigation over this portfolio.
