Copyright lawsuits in the field of artificial intelligence are on the rise again. Independent music publisher Round Hill Music recently filed a lawsuit with the U.S. Federal Court in California, taking AI giants Anthropic and Suno to court, accusing both companies of unauthorized use of hundreds of copyrighted songs to train their generation systems.

According to the complaint documents, Anthropic used at least 500 classic song lyrics from Round Hill's copyright portfolio in the training process of its chatbot Claude, including works by famous musicians such as James Brown, The Kinks, and Goo Goo Dolls, to help the large model better understand and respond to various human prompts. At the same time, Round Hill also made the same allegations against Suno, pointing out that its AI music generation system also illegally used this copyright music library for training.

Facing the escalating controversy over infringement, the music publisher revealed in both cases that, with further investigation and evidence collection, the number of involved songs is likely to expand to tens of thousands or more in the future. Based on this scale of potential infringement, the plaintiff is currently seeking a huge compensation of nearly or exceeding 1 billion U.S. dollars. As of now, neither Anthropic nor Suno has made an official public response to this lawsuit.
