(i) a translation into the latter language has been published as provided by the national law, or
(ii) a translation into the latter language has been made available to the public, by laying open for public inspection as provided by the national law, or
(iii) a translation into the latter language has been transmitted by the applicant to the actual or prospective unauthorized user of the invention claimed in the international application, or
(iv) both the acts described in (i) and (iii), or both the acts described in (ii) and (iii), have taken place.
(3) The national law of any designated State may provide that, where the international publication has been effected, on the request of the applicant, before the expiration of 18 months from the priority date, the effects provided for in paragraph (1) shall be applicable only from the expiration of 18 months from the priority date.
(4) The national law of any designated State may provide that the effects provided for in paragraph (1) shall be applicable only from the date on which a copy of the international application as published under Article 21 has been received in the national Office of or acting for such State.
