GEMA v Suno (LG München I, 42 O 763/25): Munich court rules AI music training and model memorisation infringe copyright

Verification status: IN CHECKING, not publish-ready, not pending, not verified.

The problem

Generative-AI music tools such as Suno are trained on large catalogues of recorded music, and rights-holders argue that ingesting protected works to build and run a commercial model is copyright infringement (source). GEMA, the German collecting society, brought the first European case against a generative-AI music tool, asserting infringement both in the United States, where training took place, and in Germany (source). GEMA’s chief executive Tobias Holzmüller framed the stakes bluntly, arguing that “AI models built on stolen intellectual property have no protection under the law” and that “AI service providers must pay for licences rather than helping themselves to our members’ works free of charge” (source).

What was built

Suno operates a generative-AI music generator whose behaviour is fixed in trained AI models; the case turned on models the court identified as version v3.5 and version v4 (source). GEMA’s case was that the works “seien im Rahmen des Trainings vervielfältigt worden und in dem Musikgenerator zu Grunde liegenden KI-Modell der Beklagten memorisiert” (were reproduced during training and memorised in the AI model underlying the music generator), and that further infringement occurred “durch die Ausgabe als Outputs” (through the generated outputs) (source). The dispute concerned “sechs bekannten Musikwerke” (six well-known musical works), including “Atemlos durch die Nacht”, “Rasputin”, “Big in Japan” and “Forever Young” (source).

The outcome

On 31 July 2026 the copyright-specialised 42nd Civil Chamber of the Landgericht München I “hat mit Urteil vom heutigen Tag den Ansprüchen auf Unterlassung, Auskunft und Schadensersatz der GEMA gegen SUNO … überwiegend stattgegeben (Az. 42 O 763/25)”, that is, largely upheld GEMA’s claims for cessation, disclosure and damages against Suno (source). The court was convinced that “die streitgegenständlichen Musikstücke reproduzierbar in den Modellen Version v3.5 und v4 der Beklagten enthalten” (the works at issue were reproducibly contained in the defendant’s models v3.5 and v4) (source). Independent legal press reported the same operative order: the Regional Court “ordered Suno to disclose information regarding revenue generated in connection with the infringements and to pay damages,” while noting that “the amount has not yet been determined” (source). Reporting for the trade, Music Week summarised that “by training its AI systems on songs from GEMA’s repertoire in the USA, and also by storing and reproducing them in Europe, Suno is in breach of both US and German copyright legislation” (source).

The judgment is explicitly not the last word: the court’s own release states plainly “Das Urteil ist nicht rechtskräftig” (the judgment is not final) (source). Suno “stated it disagreed with the ruling and would evaluate all available options, including an appeal” (source). No monetary award is reported here because the court set none: it ordered disclosure so that damages can later be quantified, and the amount remains open (source).

How this was verified

The strongest source here is the Landgericht München I / Bavarian Ministry of Justice press release (Pressemitteilung 16, 31 July 2026), a first-party court summary rather than the full written judgment, which had not been published in a public case database at the time of writing; every German quotation above is taken verbatim from it and it is the weakest link only in the sense that it is a summary (source). Method: the case number, date, chamber, the acts held to infringe, the six works, the memorisation finding in models v3.5 and v4, and the not-final status were all quoted verbatim from that primary release and independently corroborated by two Tier-2 legal outlets (JUVE Patent and Music Week), with the appeal statement corroborated by Variety; verification date 27 August 2026. Secondary reports disagree on the presiding judge’s name, so no judge is named here.
