AI is a tool, like your keyboard or your code editor.
Those can't own patents. That doesn't mean anything produced by those tools is public domain, it just means the attribution has to belong to a human.

They can't produce anything on their own. They have to be prompted which is initiated by humans at this point, so the patents can be owned by the initiator(human) not the tool.
The US Copyright Office disagrees. No work produced by a mechanical process, which includes LLMs, can be protected by copyright.
