Genband Inc.

GENBAND Inc. (also styled GENBAND US LLC; formerly General Bandwidth, Inc.) was founded in 1999 and headquartered at 3605 E. Plano Parkway, Plano, Texas. It was a privately held company, not exchange-listed; following a 2009–2010 recapitalization, funds affiliated with One Equity Partners (OEP) held roughly 72.5% of its equity (SEC Form S-4, 2017). The SEC merger proxy states GENBAND employed approximately 1,400 people globally as of August 2017 and reported revenue of approximately $427 million for fiscal year 2016. GENBAND merged with Sonus Networks in 2017 and became part of Ribbon Communications (NASDAQ: RBBN), which closed the combination on October 27, 2017.

Products / operations. GENBAND was an operating communications-technology vendor, not a patent-holding shell. It began as a media gateway vendor (first product, the VG-100) and grew through acquisitions into IP voice infrastructure: softswitches and media gateways (via its 2010 purchase of Nortel's Carrier VoIP and Applications Solutions business), carrier-grade security/gateway products (NextPoint Networks), IP switching for cable operators (Cedar Point Communications), session border controllers, network transformation services, and the Kandy cloud communications platform for embedding voice, video, chat and collaboration. Its customers were telecom service providers, enterprises and systems integrators.

Litigation posture. Tracked data shows GENBAND with 1 plaintiff case and 0 defendant cases, but it was an active two-way litigant rather than an NPE asserting an acquired portfolio for its own sake: it sued competitor Metaswitch over patents covering its own VoIP products, while Metaswitch sued it back in a parallel action. The tracked suit, Genband US LLC et al. v. Metaswitch Networks Corp. et al., was filed January 21, 2014 in the Eastern District of Texas, Marshall Division — a plaintiff-friendly venue then dominated by Judge Rodney Gilstrap.

Notable context. In the E.D. Tex. case (No. 2:14-cv-00033), a January 2016 jury found Metaswitch infringed six GENBAND patents and awarded about $8.17 million; the district court denied a permanent injunction, and the Federal Circuit vacated and remanded that denial in July 2017. Parallel proceedings included a Dallas County trade-secret action and a Metaswitch antitrust suit in the Southern District of New York. The asserted patents traced largely to the Nortel CVAS portfolio GENBAND acquired in 2010.
