Chapters H-II and H-III deal with the admissibility of amendments, i.e. whether the competent department of the EPO will admit amended application or patent specification documents into the procedure. After an amendment has been admitted into the procedure, the competent department must then decide whether the amendment is allowable, i.e. whether it satisfies the requirements of the EPC. It is important to note that an admissible amendment is not automatically allowable.
