We investigate how international patent activity enables firms from emerging economies to thrive in the global marketplace. We match Chinese customs data to US patent records, and leverage the quasi-random assignment of USPTO patent examiners to identify the causal effect of a US patent grant on the subsequent export performance of Chinese firms. Successful first-time patent applicants achieve significantly higher export growth, compared to otherwise similar first-time applicants that failed. This effect operates only in small part through market protection for technologically patent-related products in the US, and is largely driven by expansion in other markets. The response across destinations and products reveals that a US patent award signals the Chinese firm's capacity to produce high-quality products and credibility to honor contracts, mitigating information frictions in international trade. There is little evidence for the relaxation of financial constraints or the promotion of follow-on innovation.
