jmactacular (1755734) writes "Patents suck, and I know the difference between a provisional and a utility. But follow my logic here. If you file a provisional patent purely to try and protect yourself, wouldn't that document the "invention" sufficient as such to be considered prior art? And if prior art is a valid defense against someone else who files a patent for the same "invention", is it necessary to even file a full patent? What am I missing?"
