Sony has filed another copyright lawsuit against the AI music generator Udio, expanding its legal claims against the platform. Billboard reports that Sony’s latest filing broadens the scope of its allegations, continuing the label’s efforts to challenge Udio’s use of music-related content in AI-generated tracks. Engadget notes that Sony is the only major music label that has not signed a deal with Udio, contrasting Sony’s position with others in the industry.

Both outlets frame the new action as part of an ongoing dispute rather than a one-off filing. Billboard adds that the lawsuit comes despite licensing moves between other major labels and the platform, including reports that Universal and Warner have reached licensing arrangements described as “peace.” Taken together, the reporting indicates that Sony’s litigation strategy remains focused on its copyright claims, even as some competitors move toward deals. The articles do not provide details in the excerpts about specific works at issue, the outcome sought by Sony, or Udio’s response, beyond confirming that Sony has initiated another round of legal proceedings.
