What is an annotated drawing sheet and when is it used in patent applications?
An annotated drawing sheet is a marked-up copy of an amended drawing figure that includes annotations indicating the changes made. The MPEP provides guidance on when and how to use annotated drawing sheets:
- An annotated drawing sheet may be submitted by the applicant or required by the examiner.
- It must be clearly labeled as “Annotated Sheet.”
- The annotated sheet must be presented in the amendment or remarks section that explains the change(s) to the drawings.
The MPEP states: “A marked-up copy of any amended drawing figure, including annotations indicating the changes made, may be submitted or required by the examiner. The annotated drawing sheets must be clearly labeled as “Annotated Sheet” and must be presented in the amendment or remarks section that explains the change(s) to the drawings.“
Annotated drawing sheets are useful for clearly communicating and explaining changes made to drawings, making it easier for examiners to understand and assess the amendments. They serve as a visual guide to complement the written explanation of changes in the amendment or remarks section.
