5. Partial and multiple priorities

In cases where partial or multiple priorities can be validly claimed, the subject-matters of the subsequent application have two or more operative priority dates. In the case of a partial priority that part of the subsequent application's subject-matters disclosed in the previous application has the priority date of the previous application; for the remaining part the date of filing of the subsequent application applies. With multiple priorities, the priority of two or more previous applications is claimed. In this case, claims in the subsequent application have the priority date of the previous application in which the subject-matter subsequently claimed was disclosed (see also chapter II.D.5.2. below). Multiple priorities may be claimed for any one claim (Art. 88(2), second sentence, EPC), as long as several subject-matters are included (see also chapter II.D.5.3. below, and summary of G 1/15, OJ 2017, A82, in chapter II.D.5.3.2).
