Abstract

How should firms use patents and secrecy as appropriability mechanisms? Consider technologies that differ in the likelihood of being invented around or reverse engineered. Here, I develop the profit-maximizing strategy: (i) on the internal margin, the marginal patent balances appropriability relative to cost of patents vis-a-vis secrecy, and (ii) on the external margin, commercialize products that yield non-negative profit. To test the theory, I exploit staggered enactment of the Uniform Trade Secrets Act (UTSA), using other uniform laws as instruments. The Act was associated with 38.6% fewer patents after one year, and smaller effects in later years. The Act was associated with larger effect on companies that earned higher margins, spent more on R&D, and faced weaker enforcement of covenants not to compete. The empirical findings are consistent with businesses actively choosing between patent and secrecy as appropriability mechanisms, and appropriability affecting the number of products commercialized.
