This paper studies the impact of international patenting on corporate patenting activities, using a novel firm-level dataset from Korea. After making an overseas patent application for the first time, firms increase their overall patenting activity, both domestically and internationally, relative to similar firms that operate only in the domestic market for ideas. The improvement occurs in both cited and uncited patents, and these effects are persistent and grow over the 5-year period following international entry. Furthermore, young firms benefit more than mature firms from global engagement. Our findings suggest a role for policy.

国际专利申请对企业专利活动的影响：来自韩国的证据

本文使用韩国新颖的企业级数据集研究了国际专利申请对企业专利活动的影响。与仅在国内市场寻求创意的类似公司相比，在首次进行海外专利申请后，公司在国内和国际上的整体专利活动有所增加。被引用和未引用的专利均有所改善，并且这些影响是持续的，并在进入国际市场后的 5 年内持续增长。此外，年轻企业比成熟企业从全球参与中受益更多。我们的研究结果表明政策的作用。
