Making sure inventors get rich is not the aim of the patent-system. Most people work hard every day and there isn't a system in place to make sure they will all profit from that real big one day. So yes - there are people which profit from the patent-system, as there are always people which profit from a monopoly. And exceptionally one of those people profiting from it is even the one who put most work in it. So it might be a slightly better system than a pure lottery. Except that I'm not forced to play lottery, while I'm forced to partake in the patent-system. I would prefer not doing so. Make it an open-choice and I'm fine with it, because then I will avoid taking part in the patent-lottery as much as I avoid taking part in any other lottery. And don't worry, that won't stop me from inventing, actually it will make working for me on new stuff a lot easier.
