Article 6

1. Registration of a mark at the International Bureau is effected for twenty years, with the possibility of renewal under the conditions specified in Article 7.

 

2. Upon expiration of a period of five years from the date of the international registration, such registration shall become independent of the national mark registered earlier in the country of origin, subject to the following provisions.

 

3. The protection resulting from the international registration, whether or not it has been the subject of a transfer, may no longer be invoked, in whole or in part, if, within five years from the date of the international registration, the national mark, registered earlier in the country of origin in accordance with Article 1, no longer enjoys, in whole or in part, legal protection in that country. This provision shall also apply when legal protection has later ceased as the result of an action begun before the expiration of the period of five years.

 

4. In the case of voluntary or ex officio cancellation, the Office of the country of origin shall request the cancellation of the mark at the International Bureau, and the latter shall effect the cancellation. In the case of judicial action, the said Office shall send to the International Bureau, ex officio or at the request of the plaintiff, a copy of the complaint or any other documentary evidence that an action has begun, and also of the final decision of the court; the Bureau shall enter notice thereof in the International Register.
