Rights holders for Elvis Presley’s music filed a lawsuit against Anthropic on October 23. They allege that lyrics from 274 songs were used to train Claude without permission and that the model generated altered versions close to the originals. Anthropic says it disagrees with the claims and will defend the case. This is a new dispute over training-data use and output similarity, not a judgment establishing infringement. Because reports differ on the amount sought, no damages figure is presented as settled.
