The short answer is not automatically, but there is a streamlined process for filing patents in the US and then the EU. https://www.epo.org/ https://www.epo.org/ I suspect that US evergreen patents would be annoying to the EU if pointed out, though. I don't really get the desire to make your own FPGAs though. They will probably end up being slower and more expensive. It makes more sense to me to work on toolchain software.
