The Oberlandesgericht Dusseldorf (Higher State Court) is the superior court to the Landgerichte (Provincial Courts) of Dusseldorf, Duisburg, Wuppertal, Krefeld, Mönchengladbach and Kleve. Along with Cologne and Hamm, it serves as one of the three upper courts in the state of North Rhine Westphalia. It is the place of appeal in its area of jurisdiction.
The higher regional court of Dusseldorf is the youngest of three higher regional courts in NRW. Founded in 1906 from parts of the higher regional court districts of Hamm and Cologne, it is the second largest higher regional court in the state.
The court of Dusseldorf has a few very significant jurisdictions and competes strongly with London on patent issues. Additionally, the court is responsible for the education and support of judicial education: the first judicial exams, overseen by the in-house examination board and the support of all articled clerks and law students.
