We validate this empirically using the American Inventors Protection Act (AIPA), three complementary identification strategies, and a new measure of blocked future patent applications. We show that AIPA—intended to reduce duplication, through default disclosure of patent applications 18 months after filing—reduced duplication in the U.S. and European patent systems. The blocking measure provides a clear and micro measure of technological competition that can be aggregated to facilitate the empirical investigation of innovation, firm strategy, and the positive and negative externalities of patenting. </jats:p><jats:p> This paper was accepted by Joshua Gans, business strategy. </jats:p> Institute for Operations Research and the Management Sciences (INFORMS)2020 eng Management Science and Operations ResearchStrategy and Management 0025-1909 1526-550110.1287/mnsc.2019.3521 6662677-2685 S.
