AbstractReverse innovation (RI) patents, which apply to intellectual property that is created in an emerging country but patented in a developed country, are better representatives of innovation value than domestic patents in emerging economies. We argue that RI patents contribute to firm value by proxying for the private value of innovation, generating product market value, and signalling firms’ capabilities. Using a sample of Chinese‐listed companies, we find RI patents positively relate to firms’ short‐ and long‐term market value. This effect is stronger for firms with high innovative intensity and managerial ability. We also explore the mechanisms behind the relationship between RI and firm value. We demonstrate that, in addition to the domestic patent functions of creating value and capturing innovation rent, RI patents can further leverage firm value by signalling firm quality to customers and investors in developed markets, a function that is unique to RI patents.
