We identify strong cross-border property rights as a driver for the globalization of innovation. Using 67 million patents from over 100 patent offices, we construct novel measures of the three stages of innovation diffusion: adoption, sourcing, and collaboration. Exploiting staggered bilateral investment treaties (BITs) as shocks to cross-border property rights, we show that signatory countries increase technology adoption and sourcing from each other; they also increase R&D collaborations. The results are particularly strong for countries with weak domestic institutions and technologies with high imitation risks. Increases in R&D-related foreign investments explain most of the results.
