This paper explores the impact that the U.S.-China trade war imposed on the patent litigation risk faced by U.S.-listed Chinese firms. A Difference-in-Differences (DID) approach on a sample of 503 firms during the period 2010 through 2022 illustrates that in sectors affected by Section 301 tariffs, there was a rise in patent litigation against these firms. Yet, the mechanisms that lessened this danger were varied. While no inhibiting mechanism was found among institutional factors such as foreign directorships or the presence of a Hong Kong listing, suggesting that symbolic legitimacy is less important in safeguarding against geopolitical litigation risk, economic deterrence was found to work effectively. Ahigh market concentration ratio and R&D intensity were found to significantly reduce the rise in litigation. This paper therefore supports the idea that geopolitical litigation risk is better safeguarded by hard power concepts such as mutual forbearance or the ability to retaliate.
