Format and details of "supplement" in patent application

Write simply before and after revision. If the correction is a picture, I don't know why you want to make up the picture.

If not, before correction: Figure 3 is not clear. After correction: clear.

If the original drawing is not a formal drawing, then before revision: informal, after revision: formal.

There is also the simplest method: before correction: the picture is defective, and after correction: the defect is corrected.

If a detailed explanation is needed, the reasons can be explained in a statement of opinions, or additional drawings can be attached to the annex list.
