Yeah the current guidance from US copyright office is that if it were said to be solely authored by copilot it would not be eligible for copyright. If it were said to be solely authored by human A (who happened to use co-pilot) the elements and arrangement of it not generated by co-pilot would be copyrightable. I’m not sure the copyright office has released guidance on attempting to register AI as a co-author I assume the registration would be rejected but you’d be able to re-submit as sole Human author.
