When it was patented? When I was working with AI about 15 years ago I was experimenting with conv nn to generate audio. I wouldn't have expected for this to be patented as this is so friggin obvious thing to do. It is like patenting 2+2=4 once you discover numbers.
I am not a scientist, just I was very interested in that space and it would be a long way to create scientific paper out of my experiments. Since patent law has been created for the privileged to reap profits I wouldn't stand a chance contesting that.
