You're spreading misinformation. There hasn't been any ruling or precedent. The copyright office issued guidance, which reflects only the office’s interpretation based on its experience. It isn’t binding in the courts and guidance from the office is not a substitute for legal advice, nor it does not create any rights or obligations for anyone. They are the lowest rung on the ladder for deciding what law means.
"We conclude that Ms. Kashtanova is the author of the Work’s text as well as the selection, coordination, and arrangement of the Work’s written and visual elements," reads the copyright letter. "That authorship is protected by copyright. However, as discussed below, the images in the Work that were generated by the Midjourney technology are not the product of human authorship."
The case was unique because an inventor named Stephen Thaler listed his computer system as the artwork’s creator, arguing that a copyright should be issued and transferred to him as the machine’s owner. After the U.S. Copyright Office repeatedly rejected his request, Thaler sued the agency’s director.
He tried to get copyright for a computer as the author. Copyright is something only humans can hold. This is something entirely different.
The ruling in Thaler v. Perlmutter is about something else entirely. He tried to argue that
the AI itself was the author and that copyright should pass to him as he
hired it.
It doesn’t matter what he argued. What matters is the judge’s decision, and that was about whether AI generated material is copyrightable in the first place. The judge agreed on a summary judgement based on the Copyright Office’s claims, not the plaintiff’s claims. That is legal precedent.
U.S. District Court Rules That AI-Generated Artwork Is Not Eligible for Copyright Registration
It even goes on to say:
Because Judge Howell found that "Recent Entrance" was never even eligible for copyright protection, she did not address Dr. Thaler’s work-for-hire argument. The only question relevant to the ruling was whether a work generated autonomously by AI is protectable under the copyright law – to which the court responded with a definitive no.
