No this is the reason megacorps changed patents from First To Invent to First To File which means now you can invent something, Intel steals your research and patents it, and then you owe Intel for your invention.
Mostly prior art now is only if the invention was actually in use in public, and even then you have to sue the now-patent holder to invalidate the patent on your own invention.
So AMD could sue over copyright infringement since Intel copied their flow charts 1:1, but unless the chip was produced and available to purchase then they have to pay Intel.
Proof of prior art is usually a successful patent challenge

First-to-file is stupid.
