Abstract: Technology leaders protecting a technological headstart with a patent are provided with a powerful legal measure to restrict market entry. We analyze the impact of knowledge spillover on the decision to patent and the effect of varying patent breadth on the threat of market entry. An empirical test of our theoretical results suggests that (i) a large technological lead is protected by a patent only in industries with high knowledge spillover, and that (ii) patent breadth can mitigate the market entry threat.
