- March 31, 2016
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.
