German court rules Suno infringed copyrights, rejects fair use defense

德国法院裁定AI音乐生成器Suno侵犯版权，驳回合理使用抗辩

A Munich court found that Suno's v3.5 and v4 models memorized six well-known songs, reproducing original elements when prompted with lyrics, style, and title. The court held Suno—not users—responsible, since the company chose the training data and model architecture. It also applied US law and rejected Suno's fair use defense, distinguishing this case from earlier US rulings by noting the outputs were 'substantially similar' to the originals. The post does not disclose damages or the exact scope of the injunction.

Why it matters: First German court ruling that an AI music model infringed copyright, with a solid testing methodology and clear liability assignment. Not scored higher because it's a single source and full ruling details aren't public yet.
