Christian Helmers and Luke McDonagh are based at the Universidad Carlos III de Madrid and Cardiff University, respectively. Over the course of this article we analyse the complete set of patent cases filed at the Patents Court in England and Wales during the period 2000–2008. The data cover all types of patent-related cases brought before the Patents County Court, the Patents Court at the High Court, the Court of Appeal, as well as the House of Lords/Supreme Court. We combine the detailed information on court cases with information on the patents in dispute as well as firm-level data for the litigating parties. Our analysis looks at patent cases from three different angles: litigant-level, patent-level, and case-level. In this respect we draw a number of conclusions about the types of claims brought, and by whom, as well as the value of the patents litigated and the case outcomes.
