The applicant shall furnish a drawing where necessary for the understanding of the subject matter to be patented. When the nature of such subject matter admits of illustration by a drawing and the applicant has not furnished such a drawing, the Commissioner may require its submission within a time period of not less than two months from the sending of a notice thereof. Drawings submitted after the filing date of the application may not be used (i) to overcome any insufficiency of the specification due to lack of an enabling disclosure or otherwise inadequate disclosure therein, or (ii) to supplement the original disclosure thereof for the purpose of interpretation of the scope of any claim.

(d) Drawings submitted after the filing date of the application may not be used to overcome any insufficiency of the specification due to lack of an enabling disclosure or otherwise inadequate disclosure therein, or to supplement the original disclosure thereof for the purpose of interpretation of the scope of any claim.

For applications filed on or after December 18, 2013, other than design applications, 35 U.S.C. 111 no longer requires that an application contain a drawing where necessary for the understanding of the subject matter sought to be patented to be entitled to a filing date. 35 U.S.C. 113 continues to provide, however, that “[t]he applicant shall furnish a drawing where necessary for the understanding of the subject matter sought to be patented” and that “[d]rawings submitted after the filing date of the application may not be used (i) to overcome any insufficiency of the specification due to lack of an enabling disclosure or otherwise inadequate disclosure therein, or (ii) to supplement the original disclosure thereof for the purpose of interpretation of the scope of any claim.” Thus, the absence of any drawing on the filing date of an application where a drawing is necessary for the understanding of the subject matter sought to be patented may result in an applicant not being able to obtain a patent for any claimed invention presented in the application, but except for design applications, the absence of any drawing on the filing of an application no longer raises a question as to whether the application is entitled to a filing date.

In accordance with pre-PLT 35 U.S.C. 111, a specification and any necessary drawing(s) are among the requirements for an application to be given a filing date. The first sentence of 35 U.S.C 113 requires a drawing to be submitted where such drawing is necessary for the understanding of the invention. In this situation, the lack of a drawing renders the application incomplete and, as such, the application cannot be given a filing date until the drawing is received. The second sentence of 35 U.S.C. 113 addresses the situation wherein a drawing is not necessary for the understanding of the invention, but the subject matter sought to be patented admits of illustration and no drawing was submitted on filing. The lack of a drawing in this situation does not render the application incomplete but rather is treated as an informality. The examiner should require such drawings in almost all such instances. Such drawings could be required during the initial processing of the application but do not have to be furnished at the time the application is filed. The applicant is given at least two months from the date of the letter requiring drawings to submit the drawing(s).

(m) Shading. The use of shading in views is encouraged if it aids in understanding the invention and if it does not reduce legibility. Shading is used to indicate the surface or shape of spherical, cylindrical, and conical elements of an object. Flat parts may also be lightly shaded. Such shading is preferred in the case of parts shown in perspective, but not for cross sections. See paragraph (h)(3) of this section. Spaced lines for shading are preferred. These lines must be thin, as few in number as practicable, and they must contrast with the rest of the drawings. As a substitute for shading, heavy lines on the shade side of objects can be used except where they superimpose on each other or obscure reference characters. Light should come from the upper left corner at an angle of 45°. Surface delineations should preferably be shown by proper shading. Solid black shading areas are not permitted, except when used to represent bar graphs or color.

(s) Copyright or Mask Work Notice. A copyright or mask work notice may appear in the drawing, but must be placed within the sight of the drawing immediately below the figure representing the copyright or mask work material and be limited to letters having a print size of.32 cm. to.64 cm. (1/8 to 1/4 inches) high. The content of the notice must be limited to only those elements provided for by law. For example, “©1983 John Doe” (17 U.S.C. 401) and “*M* John Doe” (17 U.S.C. 909) would be properly limited and, under current statutes, legally sufficient notices of copyright and mask work, respectively. Inclusion of a copyright or mask work notice will be permitted only if the authorization language set forth in § 1.71(e) is included at the beginning (preferably as the first paragraph) of the specification.

Color drawings and color photographs are permitted in design applications without the need for a petition. However, the specification of design applications filed under 35 U.S.C. 111(a) must include, or be amended to include, the reference to a drawing executed in color as provided for in 37 CFR 1.84(a)(2)(iii). Note that the drawing requirements set forth in 37 CFR 1.84 do not apply to nonprovisional international design applications, except for those set forth in 37 CFR 1.84(c). See 37 CFR 1.1061(b).

(a) Drawings. There are two acceptable categories for presenting drawings in utility and design patent applications.

• (1) Black ink. Black and white drawings are normally required. India ink, or its equivalent that secures solid black lines, must be used for drawings; or
• (2) Color. Color drawings are permitted in design applications. Where a design application contains color drawings, the application must include the number of sets of color drawings required by paragraph (a)(2)(ii) of this section and the specification must contain the reference required by paragraph (a)(2)(iii) of this section. On rare occasions, color drawings may be necessary as the only practical medium by which to disclose the subject matter sought to be patented in a utility patent application. The color drawings must be of sufficient quality such that all details in the drawings are reproducible in black and white in the printed patent. Color drawings are not permitted in international applications (see PCT Rule 11.13). The Office will accept color drawings in utility patent applications only after granting a petition filed under this paragraph explaining why the color drawings are necessary. Any such petition must include the following:
  • (i) The fee set forth in § 1.17(h);
  • (ii) One (1) set of color drawings if submitted via the USPTO patent electronic filing system, or three (3) sets of color drawings if not submitted via the USPTO patent electronic filing system; and
  • (iii) An amendment to the specification to insert (unless the specification contains or has been previously amended to contain) the following language as the first paragraph of the brief description of the drawings: The patent or application file contains at least one drawing executed in color. Copies of this patent or patent application publication with color drawing(s) will be provided by the Office upon request and payment of the necessary fee.

(b) Photographs.— (1) Black and white. Photographs, including photocopies of photographs, are not ordinarily permitted in utility and design patent applications. The Office will accept photographs in utility and design patent applications, however, if photographs are the only practicable medium for illustrating the claimed invention. For example, photographs or photomicrographs of: electrophoresis gels, blots (e.g., immunological, western, Southern, and northern), auto- radiographs, cell cultures (stained and unstained), histological tissue cross sections (stained and unstained), animals, plants, in vivo imaging, thin layer chromatography plates, crystalline structures, and, in a design patent application, ornamental effects, are acceptable. If the subject matter of the application admits of illustration by a drawing, the examiner may require a drawing in place of the photograph. The photographs must be of sufficient quality so that all details in the photographs are reproducible in the printed patent.

Black and white photographs, including photocopies of photographs, are not ordinarily permitted in utility and design patent applications. Photographs or photomicrograph printed on sensitized paper are acceptable as drawings, in lieu of India ink drawings, as are photographic images submitted via the USPTO patent electronic filing system, to illustrate inventions which are incapable of being accurately or adequately depicted by India ink drawings, e.g., electrophoresis gels, blots, (e.g., immunological, western, Southern, and northern), autoradiographs, cell cultures (stained and unstained), histological tissue cross sections (stained and unstained), animals, plants, in vivo imaging, thin layer chromatography plates, crystalline structures, metallurgical microstructures, textile fabrics, grain structures and, in a design patent application, ornamental effects. The photographs or photomicrographs must show the invention more clearly than they can be done by India ink drawings and otherwise comply with the rules concerning such drawings.

See MPEP § 608.02(c) for information relating to the location of drawings in IFW applications. See MPEP § 1503.02 for discussion of photographs used in design patent applications.

For example, photographs or photomicrographs of: electrophoresis gels, blots (e.g., immunological, western, Southern, and northern), auto- radiographs, cell cultures (stained and unstained), histological tissue cross sections (stained and unstained), animals, plants, in vivo imaging, thin layer chromatography plates, crystalline structures, and, in a design patent application, ornamental effects, are acceptable. If the subject matter of the application admits of illustration by a drawing, the examiner may require a drawing in place of the photograph. The photographs must be of sufficient quality so that all details in the photographs are reproducible in the printed patent.

Black and white photographs, including photocopies of photographs, are not ordinarily permitted in utility and design patent applications. Photographs or photomicrograph printed on sensitized paper are acceptable as drawings, in lieu of India ink drawings, as are photographic images submitted via the USPTO patent electronic filing system, to illustrate inventions which are incapable of being accurately or adequately depicted by India ink drawings, e.g., electrophoresis gels, blots, (e.g., immunological, western, Southern, and northern), autoradiographs, cell cultures (stained and unstained), histological tissue cross sections (stained and unstained), animals, plants, in vivo imaging, thin layer chromatography plates, crystalline structures, metallurgical microstructures, textile fabrics, grain structures and, in a design patent application, ornamental effects. The photographs or photomicrographs must show the invention more clearly than they can be done by India ink drawings and otherwise comply with the rules concerning such drawings.

Since design patents protect the appearance of an article, graphic drawing symbols in design patent applications should be used judiciously, as the drawing symbol may interfere with a clear showing of the design. See MPEP § 1503.02, subsection V. In addition, because color drawings may now be filed in a design application without the need for a petition, applicants may prefer to represent color using color drawings instead of using graphic symbols. See MPEP § 1503.02, subsection V, and MPEP § 608.02, subsection VIII, for the submission of color drawings in design applications.

[Editor Note: Para. (a) below is only applicable to patent applications filed under 35 U.S.C. 111 on or after December 18, 2013.]

• (a) The applicant for a patent is required to furnish a drawing of the invention where necessary for the understanding of the subject matter sought to be patented. Since corrections are the responsibility of the applicant, the original drawing(s) should be retained by the applicant for any necessary future correction.
• (b) Drawings may include illustrations which facilitate an understanding of the invention (for example, flow sheets in cases of processes, and diagrammatic views).
• (c) Whenever the nature of the subject matter sought to be patented admits of illustration by a drawing without its being necessary for the understanding of the subject matter and the applicant has not furnished such a drawing, the examiner will require its submission within a time period of not less than two months from the date of the sending of a notice thereof.
• (d) Drawings submitted after the filing date of the application may not be used to overcome any insufficiency of the specification due to lack of an enabling disclosure or otherwise inadequate disclosure therein, or to supplement the original disclosure thereof for the purpose of interpretation of the scope of any claim.

The Office of Patent Application Processing (OPAP) will make the initial decision in all new applications as to whether a drawing is “necessary” under the first sentence of 35 U.S.C. 113. A drawing will be considered necessary under the first sentence of 35 U.S.C. 113 in all applications where the drawing is referred to in the specification and one or more figures have been omitted.

A drawing will be considered necessary under the first sentence of 35 U.S.C. 113 in all applications where the drawing is referred to in the specification and one or more figures have been omitted.

Applicant should also amend the specification accordingly to refer to the new illustration at the time of submission of the drawing(s). This may obviate further correspondence where an amendment places the application in condition for allowance.

(n) Symbols. Graphical drawing symbols may be used for conventional elements when appropriate. The elements for which such symbols and labeled representations are used must be adequately identified in the specification. Known devices should be illustrated by symbols which have a universally recognized conventional meaning and are generally accepted in the art. Other symbols which are not universally recognized may be used, subject to approval by the Office, if they are not likely to be confused with existing conventional symbols, and if they are readily identifiable.

The determination under 35 U.S.C. 113 (first sentence) as to when a drawing is necessary will be handled in OPAP in accordance with the following procedure. OPAP will make the initial determination as to whether drawings are required for the understanding of the subject matter of the invention. When no drawings are included in the application as filed and drawings are required, the applicant is so informed by OPAP. A filing date will not be granted if the application was filed under 35 U.S.C. 111 before December 18, 2013 and applicant will be notified to complete the application (37 CFR 1.53(e)). If a drawing is later furnished in an application filed under 35 U.S.C. 111 before December 18, 2013, a filing date may be granted as of the date of receipt of such drawing.

Pursuant to 35 U.S.C. 171, a design application (whether filed before, on, or after December 18, 2013) must be filed with any required drawing to be entitled to a filing date.

See MPEP § 601.01(f) for treatment of design applications without drawings or applications filed prior to December 18, 2013 without drawings and MPEP § 601.01(g) for treatment of applications filed without all figures of drawings or applications, other than a design application, filed on or after December 18, 2013 without drawings.

If the examiner discovers new matter in a substitute or additional drawing, the drawing should not be entered and the examiner should describe the new matter that resulted in non-entry in the next Office action. A new drawing without such new matter may be required if the examiner determines that a drawing is needed under 37 CFR 1.81 or 37 CFR 1.83. Form paragraph 6.37, reproduced in MPEP § 608.02(h), may be used. The examiner’s decision would be reviewable by filing a petition under 37 CFR 1.181. The Technology Center (TC) Director would decide such a petition.

Form paragraph 6.37, reproduced in MPEP § 608.02(h), may be used. The examiner’s decision would be reviewable by filing a petition under 37 CFR 1.181. The Technology Center (TC) Director would decide such a petition.

If an examiner determines that a filing date should not have been granted in an application filed before December 18, 2013 because it does not contain drawings, the matter should be brought to the attention of the supervisory patent examiner (SPE) for review. If the SPE decides that drawings are required to understand the subject matter of the invention, the SPE should return the application to OPAP with a typed, signed, and dated memorandum requesting cancellation of the filing date and identifying the subject matter required to be illustrated.

All issued utility patents are presented with black and white drawings or photographs in the USPTO search systems. Accordingly, the petition must also be accompanied by a proposed amendment to insert the following language as the first paragraph in the portion of the specification containing a brief description of the drawings:

It is emphasized that a decision to grant the petition should not be regarded as an indication that color drawings or color photographs are necessary to comply with a statutory requirement. In this latter respect, clearly it is desirable to file any desired color drawings or color photographs as part of the original application papers in order to avoid issues concerning statutory defects (e.g., lack of enablement under 35 U.S.C. 112 or new matter under 35 U.S.C. 132).
