807.17 Procedures for Processing Unacceptable Amendments to Drawings
If an applicant submits an amendment to the drawing and the examining attorney determines that the amendment is unacceptable, the examining attorney must issue an Office action refusing to accept the amendment and advising the applicant that the amendment will not be entered, and that the previous drawing remains the operative drawing. If the unacceptable amended drawing has been entered into the automated records of the USPTO, the examining attorney must ensure that the automated records are modified to reflect that the previous drawing is operative.
The applicant must respond to the Office action to avoid abandonment. If the applicant submits arguments in support of acceptance of the amendment and the examining attorney determines that the amendment is still unacceptable, the examining attorney must issue a final refusal of the amendment, if the application is otherwise in condition for final action.
