This article explores how the components of the technological regime affect catching-up and leadership change in green technologies in countries that are leaders and successful latecomers. We look at the extent to which technological opportunity, cumulativeness, originality and complexity of the knowledge base, and the maturity of technology contribute to the growth of patenting in green technologies. We test the relationships using USPTO patent data in green technologies over a 40-year time span (1975–2015), distinguishing two periods (1975–1999 and 2000–2015) and controlling for country-specific variables. Our results show that opportunity, complexity, originality, and maturity of the technology are positively associated with countries’ growth of patenting in green technologies, while cumulativeness has a negative effect, but only in the second period (2000–2015). The stock of knowledge has a positive effect in the first period and a negative effect in the second one. Furthermore, we find confirmation that the process of growth in green patenting has been remarkable in successful latecomer countries (i.e., South Korea, Taiwan, and China).
