Filing of Priority Document :

Rule 21 provides that where the applicant in respect of an international application designating India has not complied with the requirements of paragraph (a) or paragraph (b) of rule 17.1 of the regulations under the Treaty, the applicant shall file with the patent office the priority document referred to in that rule before the expiration of the specified time limit. Where priority document is not in the English language, an English translation thereof duly verified by the applicant or the person duly authorized by him shall be filed within the specified time limit. Where the applicant fails to comply with the requirements as above, the appropriate office shall invite the applicant to file the priority document or the translation thereof, as the case may be, within three months from the date of such invitation, and if the applicant fails to do so, the claim of the applicant for the priority shall be disregarded.
