You don't automatically deserve for your business to succeed regardless of other commercial factors, and you certainly don't deserve money just for having an idea. Ideas are cheap, it's R&D that costs money.
I never said that I deserve automatic business success. "Reward" and "getting paid" are two different things. I do agree, however, that I expressed myself poorly. Of course the mere idea is not enough to get a patent: At the very least I should supply enough information to make my valve. Still, I shouldn't need to actually produce valves in order to deserve patent protection; after all there are dedicated research entities like CSIRO who do expend significant effort to develop technologies even though they don't develop physical products based on those technologies.
And that is how the patent system is broken, because it directly rewards ideas and not development effort. The positive outcome of the system is just a side-effect of how the system works. The whole system needs refactoring so that it directly achieves the goals above within an ethical framework that acknowledges the value of straightforward hard work over simple ideas. This would mean that a patent troll with nothing more than an idea can't walk all over a company that had the same idea and then spend $10m developing it into a commercial product.
If the non-company actually came up with a working prototype and wrote a patent that explains in detail how to copy it and demonstrably came up with the whole thing first then yes, the non-company deserves the patent. Of course this scenario is utterly unlikely. Still, patents shouldn't be about how much it cost to come up with something; they should be about whether this something advances the state of the art and is described in a precise manner that allows an average worker in the field to reproduce it. If your company spends $10m and mine spends $100k and we independently arrive at the same method of solving a particular problem then your company's claim isn't automatically more valid than mine.
If we could ensure that all granted patents are for things that advance the state of the art in a reproducible manner we'd be much closer to a reasonable system (although there'd still be work left to be done).
The Tao is like a glob pattern: used but never used up. It is like the extern void: filled with infinite possibilities.
