Artikel 13

1. [Notification of Special Requirements] Any Contracting Party whose law, at the time it becomes party to this Act, requires that designs that are the subject of the same application conform to a requirement of unity of design, unity of production or unity of use, or belong to the same set or composition of items, or that only one independent and distinct design may be claimed in a single application, may, in a declaration, notify the Director General accordingly. However, no such declaration shall affect the right of an applicant to include two or more industrial designs in an international application in accordance with Article 5(4), even if the application designates the Contracting Party that has made the declaration.
2. [Effect of Declaration] Any such declaration shall enable the Office of the Contracting Party that has made it to refuse the effects of the international registration pursuant to Article 12(1) pending compliance with the requirement notified by that Contracting Party.
3. [Further Fees Payable on Division of Registration] Where, following a notification of refusal in accordance with paragraph (2), an international registration is divided before the Office concerned in order to overcome a ground of refusal stated in the notification, that Office shall be entitled to charge a fee in respect of each additional international application that would have been necessary in order to avoid that ground of refusal.
