 1870 Priority Document and Translation Thereof [R-08.2012]

 
 PCT Rule 66 

 Procedure before the International
 Preliminary Examining Authority 

 *****

 
 66.7 Copy and Translation of Earlier Application Whose
 Priority Is Claimed 
 

 
 (a) If the International Preliminary Examining Authority
 needs a copy of the earlier application whose priority is claimed in the
 international application, the International Bureau shall, on request,
 promptly furnish such copy. If that copy is not furnished to the
 International Preliminary Examining Authority because the applicant
 failed to comply with the requirements of Rule
 17.1 , and if that earlier application was not
 filed with that Authority in its capacity as a national Office or the
 priority document is not available to that Authority from a digital
 library in accordance with the Administrative Instructions, the
 international preliminary examination report may be established as if
 the priority had not been claimed.
 

 (b) If the application whose priority is claimed in the
 international application is in a language other than the language or
 one of the languages of the International Preliminary Examining
 Authority, that Authority may, where the validity of the priority claim
 is relevant for the formulation of the opinion referred to in
 Article 33(1) , invite the applicant to furnish a
 translation in the said language or one of the said languages within two
 months from the date of the invitation. If the translation is not
 furnished within that time limit, the international preliminary
 examination report may be established as if the priority had not been
 claimed. 
 

 
 *****

 

 

 A copy of the priority document and/or a translation thereof, if the
 priority document is not in English may be required by the examiner if necessary because
 of an intervening reference.
