Abstract: We examine the spillover effect of public firm innovation disclosures on the patent trading market. Relative to equity markets, the patent market is decentralized and rife with information frictions, yet it serves as an important mechanism through which innovations reallocate to the most productive users. Using data on patent transactions, we find that going from the 25th percentile to the 75th percentile in innovation-relevant public firm disclosures – proxied by the number of innovation-relevant sentences in 10-K filings – is linked to a 13.0% to 14.9% increase in future patent sales by other parties that likely consume these disclosures. These results are consistent with financial statement disclosures generating positive information externalities useful for trading patents. The positive link between innovation-relevant firm disclosures is stronger where information asymmetry is likely greatest (transactions between public and private firms) and where information uncertainty likely prevails (transactions between private firms) relative to transactions less likely to suffer from information frictions (transactions between public firms). We corroborate that the positive link between public firm disclosures and other parties’ patent sales is likely due to the resolution of information frictions through several cross-sectional tests, the use of proprietary patent broker data, and the plausibly exogenous implementation of Edgar by public firms. Our results speak to an important, but previously underexplored, externality of financial statement disclosures – their contribution to a well-functioning patent market.
