1. [Sufficient Notification] Any notification under this Treaty or the Regulations which is sent by the Office to an address for correspondence or address for legal service indicated under Article 8(6), or any other address provided for in the Regulations for the purpose of this provision, and which complies with the provisions with respect to that notification, shall constitute a sufficient notification for the purposes of this Treaty and the Regulations.
2. [If Indications Allowing Contact Were Not Filed] Nothing in this Treaty and in the Regulations shall oblige a Contracting Party to send a notification to an applicant, owner or other interested person, if indications allowing that applicant, owner or other interested person to be contacted have not been filed with the Office.
3. [Failure to Notify] Subject to Article 10(1), where an Office does not notify an applicant, owner or other interested person of a failure to comply with any requirement under this Treaty or the Regulations, that absence of notification does not relieve that applicant, owner or other interested person of the obligation to comply with that requirement.
