A drawing objection is a formal objection in which a United States Patent and Trademark Office (USPTO) examiner states that the drawings of an application break the drawing rules. The applicant answers it by filing corrected sheets, or by amending the claims or the description, within the period set in the Office action.
Drawing objections usually cite rule 1.83 or 1.84 of title 37 of the Code of Federal Regulations (CFR), and the reply follows 37 CFR 1.121(d). The sheet standards are in the patent drawing rules checklist, and compliant sheets are described on the patent drawings page.
Drawing objection or rejection: why the difference matters
A rejection refuses a claim on the merits and can be appealed to the Patent Trial and Appeal Board (PTAB), while an objection concerns form. Under section 706.01 of the Manual of Patent Examining Procedure (MPEP), a maintained objection is reviewed only by petition to the Director. It still has to be answered, because 37 CFR 1.111(b) requires a reply to every ground of objection and rejection.
Common grounds for a patent drawing objection
The MPEP form paragraphs that examiners use show the usual grounds:
- A claimed feature is not shown. Under 37 CFR 1.83(a), the drawing must show every feature specified in the claims, so the feature is shown or cancelled from the claim.
- Reference characters do not match. A character appears in a figure but not in the description, or the reverse, contrary to 37 CFR 1.84(p)(5).
- Prior art is not labelled. A figure that shows only what is old should carry a legend such as “Prior Art”.
- Format. Lines are faint or the margins are wrong.
The first 2 grounds come from the content of the application, not from drawing technique, so a well-drawn sheet can still fail.
How to respond to a drawing objection
Step 1: Change the drawing or change the text
For a 1.83(a) objection there are 2 routes: add the feature to a figure, or cancel it from the claim. Adding it is possible only if the application as filed disclosed it, because 37 CFR 1.121(f) bars new matter. A reference character mismatch can also be fixed by amending the description.
Step 2: Prepare and explain the corrected sheets
Corrected utility patent drawings and design patent drawings comply with 37 CFR 1.84, and design drawings also with 1.152. Both use the same reply format. Every change is explained in the amendment or the remarks, and an amended figure is not labelled “amended”. Where a figure changes, the brief and detailed descriptions of the drawings are amended to match, as section 714 of the MPEP notes.
The following example is an illustration and does not describe a real project. An Office action objects that the “locking tab 34” of claim 5 is not shown. Because the description as filed explains the tab, a draftsperson adds it to FIG. 2. FIG. 1 shares the original sheet, so the replacement sheet carries both figures.
Replacement sheets, new sheets and annotated sheets
| Sheet | When it is used | Key requirement |
|---|---|---|
| Replacement Sheet | An existing sheet is changed | It is labelled “Replacement Sheet” and keeps every figure of that sheet |
| New Sheet | A figure is added on its own sheet | It is labelled “New Sheet” in the top margin |
| Annotated Sheet | A marked-up copy shows the changes | It sits where the reply explains the changes |
Deadlines and abeyance for a drawing objection
An Office action on the merits normally sets a 3-month period for reply under MPEP 710.02(b). Unless the action states otherwise, it can be extended for a fee under 37 CFR 1.136(a), but not beyond the 6-month limit in 35 U.S.C. 133.
Some formal matters can be held in abeyance under 37 CFR 1.111(b) until allowable subject matter is indicated, but drawing objections in utility and plant applications are an exception. Under 37 CFR 1.85(a), they are not held in abeyance unless the USPTO says otherwise. A request for abeyance is also not a bona fide attempt to advance the application to final action, so the corrected sheets are filed with the reply.
Preventing objections before filing
Content-based objections can usually be avoided by checking the figures against the final claims and description:
- every claimed feature appears in a figure, or as a labelled box where it is conventional;
- every reference character appears in both the figures and the description;
- figures that show only what is old carry a “Prior Art” legend.
Where objections arrive with rejections, the Office action response handles both, and similar formal checks apply to the information disclosure statement.

Frequently Asked Questions
Can a drawing objection be appealed to the PTAB?
No. An objection concerns form rather than patentability, so it is not appealed to the Patent Trial and Appeal Board. Under MPEP 706.01, an objection that the examiner maintains is reviewed only by petition to the Director of the USPTO.
What happens if a drawing objection is ignored?
The reply is incomplete, because 37 CFR 1.111(b) requires a reply to every ground of objection in the Office action. If no complete reply is filed within the period for reply, including any extension, the application can become abandoned under 35 U.S.C. 133.
What if a claimed feature is not shown in the patent drawings?
The feature must be added to a figure or cancelled from the claim, under 37 CFR 1.83(a). It can be added only if the application as filed disclosed it, because no amendment may introduce new matter under 37 CFR 1.121(f).
Is an annotated sheet required with drawing corrections?
No, not in every case. Under 37 CFR 1.121(d), a marked-up copy labelled “Annotated Sheet” may be included to show the changes, and it must be provided when the examiner requires it. It is placed in the part of the reply that explains the drawing changes.
How long to file corrected drawings after a notice of allowance?
The applicant has 3 months from the mailing date of the notice of allowability under 37 CFR 1.85(c), where that notice requires corrected drawings. The period cannot be extended under 37 CFR 1.136, and the application is abandoned if compliant drawings are not filed in time.
