The patent system is already flooded with useless and novel things. The reason is that people are hoping that over the next 20 years (or whatever) that the idea might suddenly become valuable and they can profit off it. With my idea, at least, you cannot profit from a patent unless you're already profiting in the market.
You claim that since Joe is evidently providing something the market values, we should cut his taxes.
But that's what everybody with income does. So why not cut everybody's taxes? We could do that without a sideshow of filing useless patents.
This idea
1. Does not tie rewards in any way to actual innovation.
2. Explicitly suggests that people keep things as trade secrets for a while, which negates the actual purpose of the patent system!
