This article was talking about the Thaler v. Perlmutter case - which Thaler confirmed
that the work “was autonomously generated by an AI” and “lack[ed] traditional human authorship,” but contesting the Copyright Office’s human authorship requirement and urging that AI should be “acknowledge[d] … as an author where it otherwise meets authorship criteria, with any copyright ownership vesting in the AI’s owner.”
So he was never trying to claim that he created the work or had any involvement in its creation at all. Only that he as the owner should get copyright over the work. As far as i can tell his AI generated the images without any prompt at all. So this case does nothing to further the argument over how much a prompt can be considered creative works. So none of the articles based on this case are doing any justice to what this case represents.
Though I have just been made aware of this copyright claim that does a far more damning case for prompts not being considered creative enough to be able to claim copyright. Though I don’t know if this has been tested in court yet.
