Rule 56
Missing parts of the description or missing drawings

(1) If the examination under Article 90, paragraph 1, reveals that parts of the description, or drawings referred to in the description or in the claims, appear to be missing, the European Patent Office shall invite the applicant to file the missing parts within two months. The applicant may not invoke the omission of such a communication.

(2) ⁷⁸If missing parts of the description or missing drawings are filed later than the date of filing, but within two months of the date of filing or, if a communication is issued under paragraph 1 or under Rule 56a, paragraph 1, within two months of that communication, the application shall be re-dated to the date on which the missing parts of the description or missing drawings were filed. The European Patent Office shall inform the applicant accordingly.

(3) ⁷⁹If the missing parts of the description or missing drawings are filed within the period under paragraph 2, and the application claims priority of an earlier application on the date on which the requirements laid down in Rule 40, paragraph 1, were fulfilled, the date of filing shall, provided that the missing parts of the description or the missing drawings are completely contained in the earlier application, remain the date on which the requirements laid down in Rule 40, paragraph 1, were fulfilled, where the applicant so requests and files, within the period under paragraph 2:

(a) a copy of the earlier application, unless such copy is available to the European Patent Office under Rule 53, paragraph 2;

(b) where the earlier application is not in an official language of the European Patent Office, a translation thereof in one of these languages, unless such copy is available to the European Patent Office under Rule 53, paragraph 3; and

(c) an indication as to where the missing parts of the description or the missing drawings are completely contained in the earlier application and, where applicable, in the translation thereof.  

(4) If the applicant: 

(a) fails to file the missing parts of the description or the missing drawings within the period under paragraph 1 or 2,

or

(b) withdraws under paragraph 6 any missing part of the description or missing drawing filed under paragraph 2,

any references referred to in paragraph 1 shall be deemed to be deleted, and any filing of the missing parts of the description or missing drawings shall be deemed not to have been made. The European Patent Office shall inform the applicant accordingly.

(5) If the applicant fails to comply with the requirements referred to in paragraph 3(a) to paragraph 3(c) within the period under paragraph 2, the application shall be re-dated to the date on which the missing parts of the description or missing drawings were filed. The European Patent Office shall inform the applicant accordingly.

(6) Within one month of the notification referred to in paragraph 2 or paragraph 5, last sentence, the applicant may withdraw the missing parts of the description or the missing drawings filed, in which case the re-dating shall be deemed not to have been made. The European Patent Office shall inform the applicant accordingly.
