The plaintiff is Stephen Thaler who has made a career of this litigation all over the world.

To my knowledge, he has notched only one win (i.e., granted patent) in South Africa, where patents are only cursorily examined [1].

The last word in the US is from the Federal Circuit a couple of years ago [2]. Same basic outcome: only a human being can be an inventor.

That said, the new Director of the USPTO has indicated that inventors should feel free to use AI however much they want as long as a human name is on the patent. However, it should be stressed that the Director's guidelines have not been litigated yet.
