The Korean team that announced their room temperature superconductor, which other labs are now just proving to be a working concept, have put in a patent for their findings:
https://patents.google.com/patent/WO2023027537A1/en
In that patent, they make references to a US Government patent by Salvatore Cezar Pais about his work on superconductors: https://patents.google.com/patent/US20190058105A1/en
That guy - Dr Pais - has several US government patents. https://patents.google.com/?inventor=Salvatore+Cezar+Pais
Is the inclusion of that reference meant to be some kind of red flag/trolling attempt? Or is there some weight behind his work? I recall these woo patents coming up a few years ago and then disappearing from the spotlight.
