Abstract: Recent economics of knowledge studies have highlighted the strong positive effects that the limited exhaustibility of knowledge and its cumulability exert on the recombinant generation of new technological knowledge. While existing empirical investigations primarily focus on the knowledge generation and technology production functions, the analysis of the cost of knowledge has received less attention. This paper aims to fill this gap by investigating the dynamics and determinants of patent costs in the European Union in the period 1992–2012. The analysis of patent unit costs in European countries, measured as the amount of research and development (R&D) expenditure per patent application to the European Patent Office (EPO), shows a steady decline and clear convergence toward lower levels, both in time and across countries. We find that a larger stock of patents and a higher technological variety and coherence of its composition are associated with a sharper reduction in patent costs. Our findings suggest that, in Europe, ideas have been getting cheaper.
