Frankfurt Appeals Court: A Songwriter's Lyrics Stay Protected, Even When Suno Makes the Music

Here is a situation that can come up between creative partners. One person writes the words. Another puts them through an AI music generator and posts the result. Who owns the words? On October 20, 2026, the Higher Regional Court of Frankfurt, known as the OLG Frankfurt, announced its answer for one case. The decision itself is dated October 1.

German courts apply German law, and this was an urgent-relief case, so read it as a signal, not a global rule.

What happened

The court's press release and legal reports describe the case this way. A woman says she wrote a set of lyrics herself in spring 2025. Her partner used Suno to create the music and released the song through a music distribution platform. About three months later, two versions of a song with lyrics the writer says copy hers were released on Spotify and other services by another artist, through a digital distributor. The writer sued the distributor for an injunction.

The distributor argued the song was fully AI-generated and so had no copyright protection. It relied on a private expert report that listed features it said pointed to AI, such as logical breaks, formulaic sentences, repetition and a single full chorus.

What the court decided

The Frankfurt Regional Court ruled for the writer in a judgment dated December 17, 2025. On appeal, the Higher Regional Court largely confirmed it. As the court and legal reports describe the reasoning:

• Only human creations are protected. The press release says only personal intellectual creations of a human are protected by copyright, and a text generated solely by an AI system is not.
• The writer's sworn statements carried the case. The court found her affidavits that she wrote the raw version herself to be internally convincing, and the defendant's expert report did not refute them.
• The AI "tells" were not enough. A single chorus, an exaggerated feel or a few sentences that make little sense did not, without more explanation, show AI generation. The court also found a clear narrative thread, a "Cinderella" plot that the expert also recognized.
• Later AI edits did not matter here. The court left open whether Suno was later used to adjust the text, because the key creative elements of the writer's draft were still in the published version. Because substantial original parts of her work were recognizable, the defendant infringed her rights.

Lyrics and music are treated separately

KPW, a law firm that summarized the first ruling, says the Regional Court called the lyrics "an independent linguistic work that can be used independently of the background music." It also did not treat odd breaks or missing rhymes as proof of AI, because they also occur in human-written lyrics. That separation is why the music being made with Suno did not take the words out of copyright.

KPW also explains who has to prove what. The party claiming copyright generally has to show human authorship. Once the other side raises concrete signs of AI generation, such as an expert opinion, the author has to explain the creative process in detail. Here, the sworn statements did that.

On copying, KPW reports the court found the second artist's version stayed too close to the original. The basic structure, style and key content were recognizable, some lines were copied word for word, and adding a chorus and rewording part of the text did not take the song outside the writer's copyright.

What it did not decide

• The music. The ruling concerns the lyrics only, not who owns the music Suno generated.
• Prompting. The press release notes there is little case law on whether elaborate prompting can make AI output a human work, and the court did not settle it.
• A full trial. This was an urgent-relief case, a fast-track procedure, not a trial on the merits. The court says the decision cannot be appealed.
• Other countries. It is a German decision under German copyright law and does not bind courts elsewhere.

How it compares with U.S. guidance

The U.S. Copyright Office reached a similar line in its January 2025 report on AI outputs. It said outputs can be protected by copyright only where a human author has determined sufficient expressive elements. Prompts alone are not enough. Protection can apply where a human-authored work is perceptible in an AI output, or where a human makes creative arrangements or modifications of it.

The German case asks a different question: whether a person's own words survive an AI workflow. The common thread is human authorship you can show.

What to keep, in practice

In this case, paper mattered. The writer won on sworn statements from her and her partner about how the lyrics were made. You do not need to expect a lawsuit to keep records that make a statement like that easy, and year-end is a good moment to gather them. This is general information, not legal advice. If you are in a dispute over authorship, talk to a music attorney.

• Dated drafts of your lyrics, saved before you use any AI tool, as original files rather than screenshots.
• A short note of which tool did what, and when, if you use AI anywhere in the process.
• Messages or emails with collaborators that show who wrote what.
• Writer names, PRO and publisher details entered consistently when you register or distribute. Our year-end paperwork checklist covers the licensing side.

Where this fits

This is a different kind of Suno case from the GEMA ruling in Munich, which was about training and reproduction. The Frankfurt case is about authorship. For people who license songs, it is another reason to look for clear authorship. Starchild labels every song as human-written, hybrid or AI, with the maker's own plain-language disclosure on hybrid and AI songs, and every license comes with a certificate naming the writers, which anyone can check at /verify. Our buyer's field guide explains how to read those labels.
