3 cases as defendant.
I'll research this company before writing the profile.
Let me verify the merger/parent details and the Federal Circuit 2018 case.
Overview. Genband US LLC (commonly "GENBAND," formerly General Bandwidth) was founded in 1999 and was headquartered in Plano, Texas (earlier Frisco, Texas). It was a privately held, venture-backed company that raised roughly $712 million across its life, with investors including Sevin Rosen Funds, Venrock, Oak Investment Partners and Sequoia. Reported size varies by source: PitchBook cites about 1,600 employees as of 2016, while Dealroom lists a 500–1,000 headcount band and $100–500 million revenue. On October 27, 2017, GENBAND completed a "merger of equals" with Sonus Networks, Inc.; each became a wholly owned subsidiary of a new parent renamed Sonus Networks and then Ribbon Communications Inc. (Nasdaq: RBBN). GENBAND's former holders received roughly 50% of the combined company plus a $22.5 million unsecured note. GENBAND US LLC is therefore no longer independent; it is a subsidiary within Ribbon Communications.
Products / operations. GENBAND was an operating telecommunications-equipment and software vendor, not an NPE. It sold IP-based real-time communications products for fixed, mobile and cable service providers and large enterprises — session border controllers, softswitches and integrated softswitches, media gateways, call feature servers, IMS/voice-over-IP network infrastructure, SIP trunking, small-cell/carrier Wi-Fi and network-virtualization offerings, plus the "Kandy" cloud communications platform. It held hundreds of patents, many derived from VoIP and media-gateway technology.
Litigation posture. The tracked record shows a two-way litigant: 2 plaintiff cases and 1 defendant case. This is consistent with an operating company asserting its own product patents against a direct competitor while simultaneously defending against that competitor's counter-suits — not an acquired-portfolio assertion strategy. The core disputes clustered in the plaintiff-friendly Eastern District of Texas, Marshall Division (Judge Rodney Gilstrap).
Notable cases. In Genband US LLC v. Metaswitch Networks Ltd. (E.D. Tex., filed January 2014, No. 2:14-cv-33), a jury found Metaswitch infringed seven GENBAND VoIP patents and awarded about $8.17 million; the Federal Circuit later vacated the denial of a permanent injunction (Genband US LLC v. Metaswitch Networks Corp., No. 17-1148, July 10, 2017). Metaswitch's follow-on suit, Metaswitch Networks Ltd. v. Genband US LLC (No. 2:14-cv-744), produced a defense verdict for GENBAND in March 2016; a subsequent appeal, Metaswitch Networks Ltd. v. Genband US LLC, reached the Federal Circuit in 2018. Related trade-secret and antitrust actions followed in Texas state court and the S.D.N.Y.
Metaswitch Networks Ltd. appealed the March 22, 2018 final judgment in the Genband v. Metaswitch district case involving U.S. 6,885,658. The appeal was stayed and settled in connection with the settlement of 2:18-cv-00155.
Metaswitch appealed the April 2018 final judgment in the 2:14-cv-00033 action, which included the '589 Patent. The record shows a joint notice of settlement and stay in 2019, and the district court entered a settlement/dismissal order on July 1, 2019; no Federal Circuit merits opinion was retrieved.
Mirror-image Eastern District of Texas case brought by Metaswitch against Genband and Genband Management Services. Trial ended March 17, 2016 with no damages awarded to either party; final judgment on April 14, 2016 awarded Genband costs as prevailing party. The patents-in-suit did not center on the '971 Patent.
