In the lawsuit, Jason M. Allen asks a Colorado federal court to reverse the Copyright Office’s decision on his artwork Theatre D’opera Spatialbecause it was an expression of his creativity.
Reuters says the Copyright Office refused to comment on the case while Allen in a statement complains that the office’s decision “put me in a terrible position, with no recourse against others who are blatantly and repeatedly stealing my work.”
You may not like it, but legally copyright is not based on intent. That's why if a couple hired you with the intent to shoot their wedding then they do not have copyright over your work. As a photographer you control the photos and thus retain copyright even when the intent of your photos is dictated by your employer.
The functional relationship between the employer and the photographer is basically the same as the relationship between the AI user and the AI.
