It infuriates me when I hear of these 'swipe to unlock' and 'pull to refresh' patents that actually get issued. Defensive use only when patents as pathetic as these are used is all well and good. Wasn't the patent system created to protect real innovation? A fucking slide to unlock gesture is not innovation. Now let me go and patent that 'dance to pay' gesture.
Come on, yes the patent system needs reform but inventions do need to be protected/nurtured. Disregard the details here, and when I hear people having little rants it sounds like they advocate a kind of anarchist cookbook approach to innovation saying 'fuck it, you just make it better than them, who cares if the ting you worked on for 5 years was copied in 5 minutes by xyz, just make it better than them you litigious assholes'. Suppose I said this about your fucking homework? Hey, nice answers you put in there, I just copied them because they were obvious. Fuck you.
So yeah, you say swipe to unlock is obvious, tell me what the fuck you invented that was 'obvious'? Nope? Nothing huh? Nada? Oh well, guess that makes you an expert or something.
