DISCERN 2.0: Duke Innovation & SCientific Enterprises Research Network

Together with Sharon Belenzon, Larisa Cioaca, Lia Sheer and John Shin

The DISCERN dataset, now in version 2.0, links U.S. public firms’ data from Compustat to their patents and scientific publications, providing comprehensive coverage of subsidiaries and ownership changes over time. This latest update extends coverage to 2021, transitions to open-access sources (PatentsView for patents and OpenAlex for publications), and uses SEC filings for more reliable subsidiary data. DISCERN 2.0 is freely available under the O-UDA-1.0 License, allowing unrestricted use for research and commercial purposes. This update significantly enhances the dataset’s utility for studying corporate innovation and R&D investment trends.
