Patent Filing in Europe

European patent applications can be filed at the European Patent Office (EPO) in English. The application procedure leading to grant of the European patent is carried out centrally by the EPO, and correspondence to and from the EPO can be in English. Thus, the filing costs, and the costs of the subsequent application procedure, should be significantly lower than the equivalent costs of filing individual national patent applications, which in most cases must each be carried out in the national language.
