An application must contain drawings (even though they may not meet the physical requirements referred to in III, 3) where they are referred to in the description or the claims and it is necessary therefore for the Receiving Section to make a check in that regard. Where the drawings were filed later than the date of filing of the application, the applicant is informed by the Receiving Section that the drawings and the reference to the drawings in the application will be deemed to be deleted unless the applicant requests within a non-extendable period of one month that the application be re-dated to the date on which the drawings were filed. Similarly, if the applicant has omitted to file some or all of the drawings referred to in the description or claims, he is invited to file them within a non-extendable period of one month and is informed that the application will be re-dated to the date on which they are filed or, if they are not filed within that period, that any reference to them in the application will be deemed to be deleted.

If the applicant requests the insertion of drawings by way of correction under Rule 88, second sentence, this request is to be decided upon before a communication under Rule 43 is issued. For the principles governing correction see V, 3.
