Vonage Holding Inc. — company profile
Vonage Holding Inc. (legal name Vonage Holdings Corp., commonly "Vonage") is a U.S. cloud communications provider headquartered at 101 Crawfords Corner Road, Holmdel, New Jersey. It was founded in 1998 as Min-X, renamed Vonage Holdings Corp. in 2001 (sources cite founding years of 1998–2001), and went public on the NYSE as "VG" in May 2006. On 21 July 2022 Ericsson completed an all-cash acquisition of Vonage at $21/share, an enterprise value of about $6.2 billion; Vonage is now a wholly owned Ericsson subsidiary and reports as a separate segment. PitchBook lists roughly 2,568 employees (2024); Vonage reported about $1.4 billion in sales for the 12 months to 30 September 2021, prior to acquisition.
Products / services. Vonage is an operating company, not an NPE. Historically a consumer VoIP (home phone) provider, it shifted focus to business communications. Offerings include unified communications as a service (Vonage Business Communications), cloud contact center software (Vonage Contact Center, via the NewVoiceMedia acquisition), and a communications-platform-as-a-service API business (Vonage Communications Platform, built around the acquired Nexmo), plus programmable video (TokBox). It has made numerous acquisitions including Nexmo, TokBox, NewVoiceMedia, Over.ai, and Jumper.ai.
Patent-litigation posture. Vonage is overwhelmingly a defendant in patent litigation rather than an asserter. The single tracked case lists it as plaintiff: Vonage Holding Inc. v. Nortel Networks Inc. et al., filed 17 August 2007 in the U.S. District Court for the District of Delaware. That is a one-off offensive filing; contemporaneous reporting indicates the Nortel matter resulted in no monetary damages. Vonage's larger litigation history is defensive — Verizon (2006–07), Sprint Nextel and AT&T suits over VoIP patents, in which it was found liable and paid settlements. Its one plaintiff case sits in Delaware, not a plaintiff-friendly Texas venue.
Context. The Nortel case arose during the 2006–07 VoIP patent disputes, when Vonage was simultaneously defending infringement claims from major carriers. No further tracked assertions followed, consistent with an operating company posture rather than a licensing/assertion model.
