“If desired, applicant may include a marked-up copy of any amended drawing figure, including annotations indicating the changes made. Such a marked-up copy must be clearly labeled as ‘Annotated Marked-up Drawings’, and it must be presented in the amendment or remarks section that explains the change to the drawings.”
