Global Collaborative Patents
研究了美国上市公司中发明人团队分布在美国内外的全球合作专利的普遍性和特征，发现合作专利常见于企业进入知识产权保护薄弱的新外国地区进行创新时，并与美国发明人的种族构成和发明人的跨境流动相关。
We study the prevalence and traits of global collaborative patents for U.S. public companies, where the inventor team is located both within and outside of the United States. Collaborative patents are frequently observed when a corporation is entering into a new foreign region for innovative work, especially in settings where intellectual property protection is weak. We also connect collaborative patents to the ethnic composition of the firm’s U.S. inventors and cross-border mobility of inventors within the firm. The inventor team composition has important consequences for how the new knowledge is exploited within and outside of the firm.
