Sung, E.J.“The Heterogeneous Effects of Weakening Patents on Firm Innovation Strategy” (Target journal: Management Science)

Abstract: The aim of this study is to understand the effect of changing patent strength on firms’ innovation. This study shows that the common belief that weaker patents lead to fewer innovations is wrong, while accounting for the heterogeneous patent-related strategies. I propose a cleaner test compared to previous literature using a measure closer to the concept of patenting propensity and a novel empirical approach using the reaction of firms that are not involved in the U.S. policymaking process but have stakes in the U.S. innovation market. The arguments made by the Supreme Court and Amici in court documents mirrors the debate in the academic literature and show that expected consequences are contingent on firms’ characteristics and innovation strategies. The estimated impact reveals a partial fulfillment of the objectives of the policy. While large firms in complex products industries reduce preemptive patenting, other firms use patents less as an appropriation mechanism. Nevertheless, innovative activities remain high overall, due to the availability of alternative appropriation mechanisms and the spillovers allowed by weaker patents.
