The draft European Patent Litigation Agreement (EPLA), or formally the Draft Agreement on the establishment of a European patent litigation system, was a proposed patent law agreement aimed at creating an "optional protocol to the European Patent Convention (EPC) which would commit its signatory states to an integrated judicial system, including uniform rules of procedure and a common appeal court". It differed from the Unified Patent Court Agreement in that the EPLA negotiations were coordinated from the side of the European Patent Office, rather than from the European Council and Commission and therefore also offered the possibility for non-EU states to participate.
