This appears to be confusing patent inventors with patent owners. It’s the latter who benefit and presumably are accountable for the use of the patent and potential plagiarism.
If an invention was trivial enough to be invented by AI then why should we allow that action to be patented? The expenditure of labor to research that invention was minimal and definitionally not novel.
Isn't patenting an action to protect a benefit (whichever patent or benefit would be)?
