Patent protection for complex technologies

Abstract

We analyze patent protection with sequential and complementary innovation. We argue that in these cases the classic Nordhaus trade-off between innovation and static monopoly distortions is different from the case of isolated innovations. We parametrize the degree of innovation sequentiality and complementarity and show that the optimal level of patent protection increases with both. We also address the issue of the optimal division of profit among different innovators.
