Rule 41

Rectification of deficiencies in the application documents

(1)68 If the examination provided for in Article 91, paragraph 1(a) to (d), reveals deficiencies in the European patent application, the Receiving Section shall inform the applicant accordingly and invite him to remedy the deficiencies within such period as it shall specify. The description, claims and drawings may be amended only to an extent sufficient to remedy the disclosed deficiencies in accordance with the observations of the Receiving Section.

(2) Paragraph 1 shall not apply where the applicant, while claiming priority, has omitted to indicate on filing the European patent application the date or State of first filing.

(3) Paragraph 1 shall not apply where the examination reveals that the date of the first filing given on filing the European patent application precedes the date of filing of the European patent application by more than one year. In this event the Receiving Section shall inform the applicant that there will be no right of priority for the application unless, within one month, the applicant indicates a corrected date, lying within the year preceding the date of filing of the European patent application.
