He did more than "think it up in an afternoon". Its a specific type of saw the guard is for. He measured it all out, built one, tested it, built 8 more, and loaned them all to the Home Depot (probably for free) to show them that it would reduce injuries. It did so magnificently, so they stole it like rotten little children. I'm all in against "thought patents" like software and "business methods" where the inventor does nothing but think of a way to phrase a generic activity that many people already do, but the physical device patent is still a useful thing. In general it still works like the founders intended more often than it doesn't. Its friggin hard to build real things. This guy spent real time and effort perfecting this device that really does help people. He deserved better.
