Definition of a design

A design consists of the visual ornamental characteristics embodied in, or applied to, an article of manufacture. Since a design is manifested in appearance, the subject matter of a design patent application may relate to the configuration or shape of an article, to the surface ornamentation applied to an article, or to the combination of configuration and surface ornamentation.

When the article’s design is only surface ornamentation, the design is inseparable from the article to which it is applied and cannot exist alone. The surface ornamentation must be shown applied to an article of manufacture.

In discharging its patent-related duties, the United States Patent and Trademark Office (USPTO or Office) examines applications and grants patents on inventions when applicants are entitled to them. The patent law provides for the granting of design patents to whomever invents any new, original and ornamental design for an article of manufacture.

The laws and rules governing and pertaining to design patents are linked throughout this guide. You can find to the complete list of the statutes from the United States Code (U.S.C.) and regulations from the Code of Federal Regulations (CFR) that govern design patents and their applications at the bottom of this guide.

The practice and procedures relating to design applications are set forth in chapter 1500 of the Manual of Patent Examining Procedure (MPEP)

Types of designs and modified forms

An ornamental design may be embodied in an entire article (e.g., a vase) or only a portion of an article (e.g., the handle of a cup), or may be ornamentation applied to an article. If a design is directed to just surface ornamentation, it must be shown applied to an article in the drawings. The article must be graphically distinguished from the surface ornamentation (e.g., by showing the article in broken lines). In addition, if broken lines are used for this purpose, a statement must be added to the specification explaining that the broken lines showing the article form no part of the claimed design. A similar statement would be required if a different technique were used to graphically distinguish the article from the surface ornamentation.

A design patent application must only include a single claim (37 CFR § 1.153). Designs that are independent and distinct must be filed in separate applications since they cannot be supported by a single claim. Designs are independent if there is no apparent relationship between two or more articles. For example, a pair of eyeglasses and a door handle are independent articles and their designs must be claimed in separate applications. Designs are considered distinct if they have different shapes and appearances even though they are related articles. For example, the designs for two vases having different surface ornamentation creating distinct appearances must be claimed in separate applications. However, modified forms, or embodiments of a single design concept may be filed in one application when they are not patentably distinct. For example, vases with only minimal configuration differences may be considered a single design concept and both embodiments may be included in a single application MPEP 1504.05


Invention development organizations

Invention development organizations (IDO) are private and public consulting and marketing businesses that exist to help inventors bring their inventions to market, or to otherwise profit from their ideas. While many of these organizations are legitimate, some are not. Be wary of any IDO that is willing to promote your invention or product without making a detailed inquiry into the merits of your idea and giving you a full range of options which may or may not include the pursuit of patent protection. Some IDOs will automatically recommend that you pursue patent protection for your idea with little regard for the value of any patent that may ultimately issue. For example, an IDO may recommend that you add ornamentation to your product in order to render it eligible for a design patent, but not really explain to you the purpose or effect of such a change. Because design patents protect only the appearance of an article of manufacture, it is possible that minimal differences between similar designs can render each patentable. Therefore, even though you may ultimately receive a design patent for your IDO-modified product, the protection afforded by such a patent may be somewhat limited. Finally, you should also be aware of the broad distinction between utility and design patents, and realize that a design patent may not give you the protection desired.

Protecting designs outside the United States

The rights granted by a U.S. design patent extend only within the United States and have no effect in foreign countries. Persons wishing to protect their designs in another country must apply for design protection in a specific country or regional intellectual property office. Such persons may wish to consider the filing of an international design application under the Hague Agreement Concerning the International Registration of Industrial Designs (“Hague Agreement”). An international design application has the same effect as a regularly filed application for the grant of design protection in each designated Hague Agreement member country or intergovernmental organization. See also MPEP 2900

Please note that for inventions made in the United States, the Director of the USPTO must issue a foreign filing license before an inventor can apply for design protection in a foreign country or regional intellectual property office.  The filing of a U.S. patent application serves as a request for a foreign filing license. The application’s filing receipt contains further information and guidance as to the status of applicant’s license for foreign filing. See MPEP 140 for more information on obtaining a foreign filing license.

In addition, since the laws concerning the protection of designs differ among countries, persons interested in obtaining design protection abroad are advised to seek guidance from specific foreign countries to ensure that design rights are not lost.


Elements of a design patent application

The elements of a design patent application should include the following (as set forth in 37 CFR 1.154):

  • Design application transmittal form (see USPTO form PTO/AIA/18)
  • Fee transmittal form (see USPTO form PTO/SB/17)
  • Application data sheet (see 37 CFR § 1.76 and USPTO form PTO/AIA/14)
  • Specification
  • Drawings or photographs
  • The inventor's oath or declaration (see 37 CFR § 1.153(b) and USPTO form PTO/AIA/01 or PTO/AIA/08)

Look up USPTO patent application forms.

The specification should include the following sections, where applicable, in order (a section heading in uppercase letters without underlining or bold type should precede the text of the specification sections):

  • Preamble, stating the name of the applicant, title of the design, and a brief description of the nature and intended use of the article in which the design is embodied
  • Cross-reference to related applications (unless included in the application data sheet)
  • Statement regarding federally sponsored research or development
  • Description of the figure or figures of the drawing
  • Feature description
  • A single claim

Sample specifications are included below in the disclosure examples.


Disclosure examples

So that the applicant will better understand what constitutes a complete disclosure, examples of drawing disclosures and their accompanying specifications are provided on the following pages.


The design patent application process

Preparing a successful design patent application and interacting with the USPTO until a patent is issued (i.e., prosecuting the design patent application) requires knowing patent laws and rules along with knowledge of USPTO practices and procedures. Even though the Office recommends engaging a registered patent attorney or patent agent to file and prosecute applications, a knowledgeable applicant may successfully prosecute his or her own application. For more information read about our Pro Se Assistance Program.

The drawing disclosure is a critical part of a design patent application because it depicts the claimed design. It is essential that the applicant present a set of drawings (or photographs) of the highest quality which conform to the rules and policies pertaining to the drawing disclosure of a design patent application. Changes to these drawings after the application has been filed that introduce new matter are not permitted (35 U.S.C. 132, 35 U.S.C. 112(a)). It is in applicant's best interest to ensure that the drawing disclosure is clear and complete prior to filing the application, since an incomplete or poorly prepared drawing may result in a fatally defective disclosure which cannot become a patent. It is recommended that applicant retain the services of a professional draftsperson who specializes in preparing design patent drawings. Examples of acceptable drawings and drawing disclosures are included in this guide.


Drawing examples

The two types of shading commonly employed in design patent application drawings are straight-line surface shading and stippling. Individually or in combination, they can effectively represent the character and contour of most surfaces.


Drawing symbols

Color may also be shown in pen and ink drawings by lining the surfaces of the design for color in accordance with the symbols in MPEP § 608.02. If the drawing in an application is lined for color, the following statement should be inserted in the specification for clarity and to avoid possible confusion that the lining may be surface treatment --The drawing is lined for color.-- However, lining entire surfaces of a design to show color(s) may interfere with a clear showing of the design as required by 35 U.S.C. 112(a) (or for applications filed prior to September 16, 2012, pre-AIA 35 U.S.C. 112, first paragraph), as surface shading cannot be used simultaneously to define the contours of those surfaces.

37 CFR § 1.84(n) indicates that graphic drawing symbols and other labeled representations may be used for conventional elements where appropriate, subject to approval by the Office. Also, suitable legends may be used, or may be required, in proper cases. The American National Standards Institute (ANSI) (www.ansi.org) and the International Organization for Standardization (ISO) (www.iso.org) are organizations whose numerous publications include some that pertain to graphical symbols; the symbols therein are considered to be generally acceptable in patent drawings. Although ANSI and ISO documents and other published sources may be used as guides during the selection of graphic symbols for patent drawings, the Office will not "approve" any published collection of symbols as a group because their use and clarity must be decided on a case-by-case basis. Overly specific symbols should be avoided. Symbols with unclear meanings should be labeled for clarification.

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.

The following symbols should be used to indicate various materials where the material is an important feature of the invention. The use of conventional features is very helpful in making prior art searches.
