“An AI-generated design becomes registrable with the US Copyright Office once the seller has edited it substantially.”

Section II.F of the Copyright Office's Part 2 report is titled 'Modifying or Arranging AI-Generated Content' and the Executive Summary confirms the Office analyzes 'the modification or arrangement of AI-generated outputs' as one category of human contribution to copyrightability. However, the retrieved text is truncated before that section's substantive analysis, so it does not state whether 'substantial' editing by a seller is the actual legal threshold for registrability. The Thaler v. Perlmutter opinion (Source 2) only addresses works generated entirely by AI with no human involvement and does not address the edited-derivative-work scenario at all.
