The London Agreement, formally the Agreement on the application of Article 65 of the Convention on the Grant of European Patents and sometimes referred to as the London Protocol, is a patent law agreement concluded in London on 17 October 2000 and aimed at reducing the translation costs of European patents granted under the European Patent Convention (EPC). The London Agreement is an agreement between some member states of the European Patent Organisation, and has not altered other language requirements applying to European patent applications prior to grant.
