description: Patents (as well as scientific articles, and NPL citations at the aggregate firm-level) matched to U.S. Compustat firms over the period 1980-2015. In extending the match to Compustat up to 2015, we address two major challenges: name changes and ownership changes. Our UO and subsidiary historical standardized firm name lists, including the dynamic reassignment, are publicly available for researches to match to their database of interest.
