The US Copyright Office has issued an opinion that AI generated works can't be copyrighted, but AFIK, there are no US federal court cases directly on point.
This may be overstating the state of US law a bit.
Not so. IANL, but the leading case is Thaler v. Perlmutter, the case definitively established the rule.
Computer scientist Stephen Thaler tried to register an image (A Recent Entrance to Paradise) that he said was created autonomously by his AI system, listing the AI itself as the author.
β’ Aug. 2023 β The U.S. District Court for D.C. (Judge Beryl Howell) ruled against him, holding that "human authorship is a bedrock requirement of copyright."
β’March 2025 β The D.C. Circuit Court of Appeals affirmed, holding that the Copyright Act 'requires all eligible work to be authored in the first instance by a human being'. The court pointed to multiple provisions of the Act (inheritance by a 'widow', duration tied to 'the author's death', signature requirements, etc.) that only make sense if an author is human.
β’ May 2025 β The D.C. Circuit declined to rehear the case en banc.
β’ March 2, 2026 β The Supreme Court declined to hear the appeal, letting the ruling stand.
What hasn't yet been decided is how much human effort is required. From the case, I think we can draw the conclusion that a prompt is not enough. How much more is needed is an open question.
