Abstract We examine how patent disclosures affect managerial learning. Exploiting the American Inventor’s Protection Act (AIPA) as a shock that accelerated disclosure, we document an increase in investment-Q sensitivity among firms that revealed information more quickly after AIPA’s introduction. This effect is more pronounced for firms with lower analysts coverage, higher bid–ask spreads, and lower turnover suggesting that the effect is concentrated among firms where incremental price informativeness is most valuable. Additional evidence indicates that informed trading increases following pre-grant disclosures, suggesting that sophisticated investors incorporate the newly available technical information into prices. The findings suggest that AIPA enhanced capital market feedback, thereby shaping managerial decision-making.
