For several years running, IP Edge LLC has been responsible for the most defendants added to NPE litigation campaigns throughout each calendar year. 2019 was no different. Last year saw roughly 400 defendants added to campaigns launched by plaintiffs associated with the Texas monetization firm, the campaigns spanning a wide range of technologies and now involving suits filed (and typically litigated in file-and-settle fashion) in myriad districts. A quick glance at the NPE’s January filings suggests that 2020 will see more of the same, while a recent Alice ruling may have just ended one of IP Edge’s 2019 campaigns.
Mod Stack LLC, a Texas NPE formed in June 2015, has asserted in litigation yet another patent originally issuing to former networking equipment provider Paradyne (which was acquired by Zhone Technologies in September 2005). The patent-in-suit (7,460,520) generally relates to connecting telephone calls between legacy circuit-switched networks and newer packet-switched networks. The networking devices of eight defendants—Dialogic (2:16-cv-00294), Digium (2:16-cv-00295), GenBand (2:16-cv-00296), Grandstream Networks (2:16-cv-00297), Matrix Comsec (2:16-cv-00298), Patton Electronics (2:16-cv-00299), Sangoma (2:16-cv-00300), and Sonus Networks (2:16-cv-00301)—are the accused products in the campaign.
