I mean politically Biden is doing an extremely unpopular war/genocide. Stripping patents from shitty companies is far more popular. And yeah the government can essentially do anything it wants on that front. SCOTUS will sometimes strike things down as being unconstitutional, but if you go off that logic then basically every law can be debate-broed into being unconstitutional. Which is one of many problems with SCOTUS allocating itself more power... different discussion though. But yes congress can absolutely strip a patent with minimal effort.
