I don't think you understand patents. Your discussion on the lightbulb is only from your imagination. The total number of US patents is only millions. Millions of them on lightbulb? From your words I can see you are lying. Further, Edison failed a thousand times before he succeeded. So it is not easy to make a little modification here and there to make a new lightbulb.
