  1. All estimations include USPTO patents of the filing years 1990–2015 if at least one inventor has been from Canada, China, France, Germany, Japan, South Korea, Switzerland, the UK, or the USA. Similar to the main text, the specifications use the number of forward citations as an indication of breakthrough innovations. The first model specification indicates a breakthrough innovation if the number of a patent’s five-year forward citations is among the top 25%, the second specification is similar to the used specifications in the main text, and the third specification if the number of a patent’s five-year forward citations is among the top one percent. In order to show associations in percentage points, we have multiplied the FWD-dummies by 100. The industry fixed effects are at the level of the six industries included in the interaction terms. The standard errors in parentheses are also clustered at this industry level. Significance levels for the coefficients are indicated as: \(p^*<0.1\); \(p^{**}<0.05\); \(p^{***}<0.01\)
