Okay, I need some clarifications now regarding the whole issue. I am building my web app using React and will be extending to mobile platforms using React-Native. The product is kind of paradigm change in the way we deal with education, so I will at some point consider getting a patent protecting my own interests. My questions are as follows: 1. If fb copies the entire thing, repackages it as something different and tries to make it free and open source. I wouldn't be able to sue them just because I used React and React-Native? Is that all what the patent license means or I am missing something here?
