As the costs of data handling continue to decrease, patenting information is being used increasingly by analysts and practitioners to deepen their understanding of the nature, sources and consequences of technical change. On the basis of earlier analyses, we conclude that patents granted to universities give a very partial and distorted picture of the contributions of university research to technical change. However, citations in patents to published research papers, together with collaborative publications between universities and industry, offer rich and rewarding sources of information on how university research contributes to technical change.
