What are the requirements for the amendment document when canceling a patent drawing figure?

When canceling a patent drawing figure, the amendment document should include:

• An explanation of the changes to the drawings in the remarks section.
• The marked-up (annotated) copy of the drawing sheet showing the cancellation.
• A replacement sheet of drawings without the canceled figure (if applicable).
• Amendments to the brief description of the drawings reflecting the change.

MPEP 608.02(t) states: “The marked-up (annotated) copy must be clearly labeled as ‘Annotated Sheet’ and must be presented in the amendment or remarks section of the amendment document which explains the changes to the drawings (see 37 CFR 1.121(d)(1)).” This ensures that the examiner can easily understand and process the changes made to the application.
