So you are saying a patent does not give you property rights to the sweat of your brow?
Patent law is arbitrary and unnecessary.
That's the system in China...
I'm saying there is no property right to an idea. Ideas are not analogous to real property. If I make use of the property of your house, you consequently are denied that use. If I make use of the idea that 2+2=4, you are denied nothing.
The Labour of his Body, and the Work of his Hands, we may say, are properly his. Whatsoever then he removes out of the State that Nature hath provided, and left it in, he hath mixed his Labour with, and joyned to it something that is his own, and thereby makes it his Property. - Locke
One can claim to have discovered an idea, but one cannot remove an idea from Nature and make it their own. An idea exists for all, it has no scarcity, except that artificially imposed by monopoly grants from the State. Such artificial scarcity impedes adoption, adaption, implementation, and production, with negative consequences for society by impeding the creation of wealth.
