This study investigates whether and how non-practicing entities (or “patent trolls”) affect corporate narrative R&D disclosure using demand letters. Exploiting the staggered adoption of Anti-Troll legislation in 33 U.S. states as an exogenous shock that limit trolls’ ability to send out bad-faith demand letters, we find that in response to the passage of state Anti-Troll legislation, firms tend to increase both the quantity and details of narrative R&D disclosures. These results are robust to the exclusion of firms that are prone to patent litigation initiated by patent trolls and are robust after controlling the passage of Anti-Troll legislation in firms’ non-headquarter operating states. We further find that this effect is stronger for firms facing higher proprietary costs of disclosure and for firms facing lower levels of information demand from external stakeholders. Overall, our findings suggest that patent trolls, which is an alternative source of firms’ proprietary costs, plays a crucial role in shaping a firm’s R&D disclosure strategy.
