The IP bundle of top corporate R&D investors database (EC-JRC-OECD COR&DIP©) is the result of the collaboration between the European Commission, Joint Research Centre Directorate B – Fair & Sustainable Economy, and the OECD Directorate for Science, Technology and Innovation (STI). The COR&DIP© database presents information on the Research & Development (R&D) activity and IP assets (i.e. patents and trademarks) of the top 2000 corporate R&D performers worldwide. These firm-level data allow to better understand the role the top 2000 companies can play in addressing future challenges by developing, owning and commercialising technologies. The EC-JRC-OECD COR&DIP© data are made public, both to ensure transparency and to foster further use in the scientific community.
