In design patent applications, ornamentality, novelty, nonobviousness enablement and definiteness are necessary prerequisites to the grant of a patent. The inventive novelty or unobviousness resides in the ornamental shape or configuration of the article in which the design is embodied or the surface ornamentation which is applied to or embodied in the design.

Novelty and nonobviousness of a design claim must generally be determined by a search in the pertinent design classes. It is also mandatory that the search be extended to the mechanical classes encompassing inventions of the same general type. Catalogs and trade journals as well as available foreign patent databases are also to be consulted.

If the examiner determines that the claim of the design patent application does not satisfy the statutory requirements, the examiner will set forth in detail, and may additionally summarize, the basis for all rejections in an Office action. If a reply to an Office action overcomes a rejection either by way of an amendment to the claim or by providing convincing arguments that the rejection should be withdrawn, that rejection must be indicated as withdrawn in the next Office action, unless such action is a notice of allowability. Likewise, any amendment to the specification or claim, or new drawing or drawing correction submitted in reply to an objection or objections in an Office action must be acknowledged in the next Office action, unless such action is a notice of allowability. When an examiner determines that the claim in a design application is patentable under all statutory requirements, but formal matters still need to be addressed and corrected prior to allowance, an Ex parte Quayle action will be sent to applicant indicating allowability of the claim and identifying the necessary corrections.

If it is determined that a rejection of the claim should be given after a reply to a Quayle action, the indication of allowability set forth in the previous action must be withdrawn and prosecution reopened using the following form paragraph:

With respect to pro se design applications, the examiner should notify applicant in the first Office action that it may be desirable for applicant to employ the services of a registered patent attorney or agent to prosecute the application. Applicant should also be notified that the U.S. Patent and Trademark Office cannot aid in the selection of an attorney or agent. See MPEP § 401. If it appears that patentable subject matter is present and the disclosure of the claimed design complies with the requirements of 35 U.S.C. 112, the examiner should include a copy of the “Guide To Filing A Design Patent Application” with the first Office action and notify applicant that it may be desirable to employ the services of a professional patent draftsperson familiar with design practice to prepare the drawings. Applicant should also be notified that the U.S. Patent and Trademark Office cannot aid in the selection of a draftsperson. The following form paragraph, where appropriate, may be used.
