The elements of a design patent application should include the following:

(1) Preamble, stating 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;

(2) Cross-reference to related applications (unless included in the application data sheet).

(3) Statement regarding federally sponsored research or development.

(4) Description of the figure(s) of the drawing;

(5) Feature description;

(6) A single claim;

(7) Drawings or photographs;

(8) Executed oath or declaration.

In addition, the filing fee, search fee, and examination fee are also required. If applicant is a small entity, (an independent inventor, a small business concern, or a non-profit organization), these fees are reduced by half.

Of primary importance in a design patent application is the drawing disclosure, which illustrates the design being claimed. Unlike a utility application, where the "claim" describes the invention in a lengthy written explanation, the claim in a design patent application protects the overall visual appearance of the design, "described" in the drawings.

It is essential that the applicant present a set of drawings (or photographs) of the highest quality which conform to the rules and standards which are reproduced in this guide. Changes to these drawings after the application has been filed, may introduce new matter, which is not permitted by law (35 U.S.C. 132). 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 so that applicant will have some idea of what is required and can prepare the drawings accordingly.

The preparation of a design patent application and the conducting of the proceedings in the USPTO to obtain the patent is an undertaking requiring the knowledge of patent law and rules and Patent and Trademark Office practice and procedures. A patent attorney or agent specially trained in this field is best able to secure the greatest patent protection to which applicant is entitled.

It would be prudent to seek the services of a registered patent attorney or agent. Representation, however, is not required. A knowledgeable applicant may successfully prosecute his or her own application. However, while persons not skilled in this work may obtain a patent in many cases, there is no assurance that the patent obtained would adequately protect the particular design.
