Inventors and Impostors: An Analysis of Patent Examination With Self-Selection of Firms into R&D
Tilburg Law and Economics Center (TILEC); Tilburg University - Center and Faculty of Economics and Business Administration
TILEC Discussion Paper No. 2012-026
I present a model in which firms differing in R&D productivity choose between ambitious research projects, which are socially desirable, and unambitious ones, which are socially undesirable. The patent office must decide how rigorously to examine applications, which affects the probability of weeding out bad applications but also how firms self-select into more or less ambitious projects. Both the ex post and ex ante welfare effects need to be taken into account in determining the optimal examination intensity. The model allows me to assess the impact of various policy changes on examination and welfare, including the creation of specialized patent courts, post-grant opposition, and the delegation of fee-setting authority to the patent office. It generates a number of predictions that are consistent with empirical evidence on the patent system.
