      When responding to USPTO objections to drawing informalities, new drawings are submitted with the words “Replacement Sheet” in the top margin, as per 37 CFR 1.121(d) below. The PCT does not require, but also does not object to “Replacement Sheet” labeling; rather, the PCT itself marks incoming replacement sheets as “substitute” or “rectified” sheets according to their Administrative Instructions, Section 325.

      When replacement drawings are being submitted to the USPTO, they must say “Replacement Sheet” in the top margins,

      When drawings are only submitted to the PCT, the “Replacement Sheet” header is omitted.

      Replacement drawings submitted to both the USPTO and the PCT can include the “Replacement Sheet” text.

      37 CFR 1.121(d)

      (d) Drawings : One or more application drawings shall be amended in the following manner: Any changes to an application drawing must be in compliance with § 1.84 and must be submitted on a replacement sheet of drawings which shall be an attachment to the amendment document and, in the top margin, labeled “Replacement Sheet”. Any replacement sheet of drawings shall include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is amended. Any new sheet of drawings containing an additional figure must be labeled in the top margin as “New Sheet”. All changes to the drawings shall be explained, in detail, in either the drawing amendment or remarks section of the amendment paper.
