Voxer IP LLC is a Delaware limited liability company and a wholly owned subsidiary of Voxer, Inc.. The parent company, Voxer, Inc., also referred to as just Voxer, was founded in 2007 by Tom Katis and Matt Ranney. Voxer's headquarters are in San Francisco, California, though some sources also indicate Dallas, Texas. As of March 2026, Voxer employs approximately 25 people, with an estimated annual revenue of $2.8 million as of 2024. The company has raised over $30 million in venture financing.
Voxer develops and offers a mobile push-to-talk (PTT) voice messaging application known as Voxer Walkie Talkie. The app allows for live and recorded voice communication, text, photos, and video messages across various operating systems like iOS and Android. It also features group chats, location sharing, voice-to-text transcription, and advanced administrative controls for business users. The technology behind Voxer's services centers on "live messaging and store-and-stream technologies," enabling immediate and time-shifted media consumption.
Voxer IP LLC primarily operates as a patent assertion entity, asserting an acquired portfolio of patents related to telecommunications and multimedia management. All four tracked cases show Voxer IP LLC as the plaintiff and none as a defendant, indicating a focused patent monetization strategy. The cases are filed in the U.S. District Court for the District of Delaware.
Notably, Voxer IP LLC and its parent, Voxer, Inc., have been involved in significant patent litigation. In 2020, they sued Meta Platforms (then Facebook, Inc.) in the Western District of Texas, alleging infringement of patents related to live messaging and store-and-stream technologies used in Facebook Live and Instagram Live. A jury awarded Voxer over $174.5 million in royalty damages in July 2023, though the parties later settled the dispute. The most recent tracked cases, filed on July 14, 2025, are against Amazon.com, Inc. and Google, LLC, alleging infringement of video communication patents. Two of the five patents asserted against Amazon and Twitch were also part of the Meta lawsuit.
