Rule 5

1. [Procedure in Case of Non-Compliance with Requirements] If the application does not, at the time of its receipt by the Office, comply with any of the applicable requirements of Article 5(1)(a) or (2)(a), the Office shall promptly invite the applicant to comply with such requirements within a time limit indicated in the invitation, which time limit shall be at least one month from the date of the invitation where the applicant’s address is on the territory of the Contracting Party concerned and at least two months where the applicant’s address is outside the territory of the Contracting Party concerned. Compliance with the invitation may be subject to the payment of a special fee. Even if the Office fails to send the said invitation, the said requirements remain unaffected.
