- 2026-03-31
Newly filed patent infringement suit in the Western District of Texas. An Ex Parte complaint analysis identifies US 10491646 as the patent-in-suit.
Plaintiff
7 cases as plaintiff.
Company overview. DynaMuse LLC is a private limited-liability company that appears in court filings as a New Mexico-based entity and owns at least one U.S. patent. No public operating business, website, employee count, revenue, or parent company is identifiable from public sources; incorporation date and ownership structure are not publicly confirmed.
Products / services / operations. DynaMuse has no discernible product or service operations. It is a non-practicing entity: the Stanford NPE Litigation Database lists it as a "Non Practicing Entity" asserting "acquired patents," and RPX-type commentary has characterized its activity as monetization litigation. Its asserted portfolio centers on U.S. Patent No. 10,491,646, "Mechanism for facilitating user-controlled features relating to media content in multiple online media communities and networks" (issued Nov. 26, 2019; filed 2015; priority 2012), which covers a "playlist assistance" function that searches a user's playlists across online media services to show which playlists contain a selected song, artist, or genre.
Patent-litigation posture. DynaMuse is a pure plaintiff: all 7 tracked cases are infringement suits it filed, with zero appearances as a defendant. Every target is an online-music or audio-streaming service — SoundCloud, Mixcloud, IDAGIO, Deezer, Xandrie (Deezer's French parent), Sirius XM Radio, and iHeartMedia — whose playlist features allegedly practice the '646 patent. The suits cluster in plaintiff-friendly Texas venues: four were filed in the Eastern District of Texas (assigned to Judge Rodney Gilstrap and consolidated), with later cases in the Western and Northern Districts. Counsel of record is Rabicoff Law LLC, a firm that regularly represents NPE plaintiffs.
Notable context. The November 2025 E.D. Tex. wave against SoundCloud, Mixcloud, IDAGIO, and Deezer/Xandrie was consolidated for pretrial purposes, and at least the SoundCloud action was voluntarily dismissed with prejudice in January 2026. Subsequent 2026 filings against Sirius XM and iHeartMedia suggest an ongoing enforcement campaign against streaming platforms around playlist-search functionality. No funding sources, licensees, or prior licensing history are publicly documented.
