Two distinct theories of patents - the reward theory and the contract theory - are customarily adopted by the courts to justify the patent system. The reward theory maintains that the function of the patent system is to remunerate successful innovators so as to encourage R&D effort. In contrast,...

We analyze optimal patent design when innovators can rely on secrecy to protect their innovations. Secrecy provides a temporary monopoly, which terminates when the secret leaks out or the innovation is duplicated. We find conditions under which the optimal policy is to induce the first innovator...

In this paper we look at patents as alternative to trade secrets. We disentangle the disclosure motive for patent protection from the traditional reward motive by adjusting the level of patent protection so as to make the innovator just indifferent between patenting and keeping the innovation...

We analyze optimal patent design when innovators can rely on secrecy to protect their innovations. Secrecy has no fixed term but does not preclude accidental disclosure nor independent creation by other inventors. We derive the optimal scope of the rights conferred to such second inventors,...
