When an invention is made, the inventor
has three possible courses of action open to him: he can give the invention to
the world by publishing it, keep the idea secret, or patent it. A granted patent is the result of a bargain made between an inventor and the state, by which the inventor gets a limited period of monopoly (垄断) and publishes full details of his invention to the public after that period terminates (终止).
