description: The project collects all utility patents granted from the Korea Intellectual Property Office (KIPO) for the period 1948-2016 and the US Patent and Trademark Office (USPTO) for the period 1976-2017. The project also matches their assignees to firms in DataGuide 5.0, a Korean financial database. The resulting dataset includes total 14,803 listed and non-listed Korean firms matched with their Korean and US patents, in addition to a host of accounting and financial information. Over 45% of all sample KIPO patents and 87% of US patents assigned to Korean assignees are matched.
