Guys, thank you indeed very much for everyone here, but my system had already been published by someone else, luckily for me since at least june 2023 according to wayback machine. I still though feel uneasy about this since I had the idea since 2022 but no knowledge about patents. If someone knows this was published before 2022, I’d be delighted. If not, well, that’s painful but I’ll keep going forward.
