Objectives. The main objective of the present study is to provide a comprehensive coverage of the patenting activity at the European Patent Office by companies in the remit of the fourth industrial revolution (4IR). We also aim at moving forward the understanding of the firm-level patenting activity of 4IR technologies.

Methodology. We do so by conducting an empirical assessment of the development of technologies related to the 4IR via the analysis of patents filed at the European Patent Office between 1985 and 2014. We employ a new matched patent-firm data set provided by the Bureau Van Dijk: ORBIS-IP.

Findings. In line with results from the recent literature, we find evidence of a surge in patenting activity related to the 4IR in the past three decades, particularly in networked devices. Our results also suggest that firms filing 4IR patents have become progressively younger on average. At the same time, we find a steady growth in the average number of 4IR patent applications filed yearly by each company.
