Artikel 15

(1). This Convention shall enter into force three months after ten States members of the Paris Union and seven States members of the Berne Union have taken action as provided in Article 14 (1), it being understood that, if a State is a member of both Unions, it will be counted in both groups. On that date, this Convention shall enter into force also in respect of States which, not being members of either of the two Unions, have taken action as provided in Article 14 (1) three months or more prior to that date.
(2). In respect to any other State, this Convention shall enter into force three months after the date on which such State takes action as provided in Article 14 (1).
