This is what I find confusing, the blog post mentions a patent license that you are granted, but as you say, nobody is aware of any patent covering React. React's doesn't seem to use any novel technique in the field of CS. But https://github.com/facebook/react/blob/b8ba8c83f318b84e42933f6928f231dc0918f864/PATENTS https://github.com/facebook/react/blob/b8ba8c83f318b84e42933... , the way I read it says they grant you a license to to "make, have made, use, sell, offer to sell, import, and otherwise transfer" the React Software. They don't seem to give you a license to any patent.
