One interesting thing to note is that the actual license makes no specific references to the patents rider, and in fact the patents grant rider is a separate file completely. Does that mean that I have to follow it, if it's not directly in the license? If we look at the license as a contract, shouldn't it be in the license directly, even if it's referencing something outside?
