Requirement for Prima Facie Showing of Lack of Ornamentality
Note:
An examiner must demonstrate that a claimed design lacks ornamentality and provide evidence to support such a claim.

To properly reject a claimed design under 35 U.S.C. 171 on the basis of a lack of ornamentality, an examiner must make a prima facie showing that the claimed design lacks ornamentality and provide a sufficient evidentiary basis for factual assumptions relied upon in such showing. See In re Jung, 637 F.3d 1356, 1362, 98 USPQ2d 1174, 1177 (Fed. Cir. 2011). See, e.g., In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992), (“the examiner bears the initial burden, on review of the prior art or on any other ground, of presenting a prima facie case of unpatentability.”).

Ornamental Design Must Be Evaluated Directly And With Additional Evidence
Note:
The design's ornamental aspects must be assessed directly, with additional evidence like visibility during use considered to support the evaluation.

Knowledge that the article would be hidden during its end use based on the examiner’s experience in a given art or information that may have been submitted in the application itself would not be considered prima facie evidence of the functional nature of the design. See Seiko Epson Corp v. Nu-Kote Int’l Inc., 190 F.3d 1360, 52 USPQ2d 1011 (Fed. Cir. 1999). “Visibility during an article’s ‘normal use’ is not a statutory requirement of § 171, but rather a guideline for courts to employ in determining whether the patented features are ‘ornamental’.” See Larson v. Classic Corp., 683 F. Supp. 1202, 7 USPQ2d 1747 (N.D. Ill. 1988). If there is sufficient evidence to show that a specific design "is clearly intended to be noticed during the process of sale and equally clearly intended to be completely hidden from view in the final use," it is not necessary that a rejection be made under 35 U.S.C. 171. See In re Webb, 916 F.2d 1553, 1558, 16 USPQ2d 1433, 1436 (Fed. Cir. 1990). The mere fact that an article would be hidden during its ultimate end use is not the basis for a rejection under 35 U.S.C. 171, but this information provides additional evidence to be used in support of the contention that the design lacks ornamentality. The only basis for rejecting a claim under 35 U.S.C. 171 as lacking in ornamentality is an evaluation of the design itself in light of additional information, such as that identified above.

Burden of Proof Shifting to Applicant After Prima Facie Case Established for Lack of Ornamentality
Note:
After the examiner establishes a proper prima facie case of lack of ornamentality, the applicant must provide evidence or arguments to rebut the rejection.

When the examiner has established a proper prima facie case of lack of ornamentality, “the burden of coming forward with evidence or argument shifts to the applicant.” See In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992). A rejection under 35 U.S.C. 171 for lack of ornamentality may be overcome by providing evidence from the inventor himself or a representative of the company that commissioned the design that there was an intent to create a design for the “purpose of ornamenting.” See In re Carletti, 328 F.2d 1020, 1022, 140 USPQ 653, 654 (CCPA 1964). Attorney’s arguments are not a substitute for evidence. Once a proper prima facie case of lack of ornamentality is established by the examiner, it is incumbent upon applicant to come forth with countervailing evidence to rebut the rejection made by the examiner. See Ex parte Webb, 30 USPQ2d 1064, 1067-68 (Bd. Pat. App. & Int. 1993). Form paragraph 15.08 or 15.08.01, where appropriate, may be used to reject a claim under 35 U.S.C. 171 for lack of ornamentality.

Evidence to Overcome Lack of Ornamentality Rejection
Note:
Provide evidence such as affidavits, advertisements, and design representative statements to demonstrate the ornamental features of a design patent.
A rejection under 35 U.S.C. 171 based on lack of ornamentality may be overcome by the following:
  • (A) An affidavit or declaration under 37 CFR 1.132 submitted from the applicant or a representative of the company, which commissioned the design, explaining specifically and in depth, which features or area of the claimed design were created with:
    • (1) a concern for enhancing the saleable value or increasing demand for the article. See Gorham Manufacturing Co. v. White, 81 U.S. (14 Wall) 511 (1871), or
    • (2) a concern primarily for the esthetic appearance of the article;
  • (B) Advertisements which emphasize the ornamentality of the article embodying the claimed design may be submitted as evidence to rebut the rejection. See Berry Sterling Corp. v. Pescor Plastics Inc., 122 F.3d 1452, 43 USPQ2d 1953 (Fed. Cir. 1997);
  • (C) Evidence that the appearance of the design is ornamental may be shown by distinctness from the prior art as well as an attempt to develop or to maintain consumer recognition of the article embodying the design. See Seiko Epson Corp. v. Nu-Kote Int’l Inc., 190 F.3d 1360, 52 USPQ2d 1011 (Fed. Cir. 1999);
  • (D) Evidence may be provided by a representative of the company, which commissioned the design, to establish the ornamentality of the design by stating the motivating factors behind the creation of the design;
  • (E) When the rejection asserts that the design is purely dictated by functional considerations, evidence may be presented showing possible alternative designs which could have served the same function indicating that the appearance of the claimed design was not purely dictated by function. See L.A. Gear Inc. v. Thom McAn Shoe Co., 988 F.2d 1117, 25 USPQ2d 1913 (Fed. Cir. 1993);
  • (F) When the rejection asserts no period in the commercial life of the article when its ornamentality may be a matter of concern, the applicant must establish that the “article’s design is a ‘matter of concern’ because of the nature of its visibility at some point between its manufacture or assembly and its ultimate use.” See In re Webb, 916 F.2d 1553, 1558, 16 USPQ2d 1433, 1436 (Fed.

Proper Basis for Ornamentality Rejection
Note:
The proper evidentiary basis for rejecting a claim as lacking ornamentality is an evaluation of the design's appearance, supplemented by relevant information if needed.

The proper evidentiary basis for a rejection under 35 U.S.C. 171 that a claim is lacking in ornamentality is an evaluation of the appearance of the design itself. The examiner’s knowledge of the art, a reply to a letter of inquiry, a brochure emphasizing the functional/mechanical features of the design, the specification of an analogous utility patent (the applicant’s or another inventor), or information provided in the specification may be used to supplement the analysis of the design. If a design is embodied in a specific mechanical article, the analysis that the design lacks ornamentality because its appearance is dictated by functional requirements should be supported by reference to utility patents or some other source of information about the function of the design. If the design is embodied in an article that has a more general use, such as a clip, the analysis and explanation as to why the design lacks ornamentality should be detailed and specific. The examiner’s contention that the specific appearance of the claimed design lacks ornamentality may be supported by In re Carletti et al., 328 F.2d 1020, 140 USPQ 653 (CCPA 1964) (a design to be patentable must be “created for the purpose of ornamenting” the article in which it is embodied.). The presence or lack of ornamentality must be made on a case by case basis.

The examiner’s knowledge of the art, a reply to a letter of inquiry, a brochure emphasizing the functional/mechanical features of the design, the specification of an analogous utility patent (the applicant’s or another inventor), or information provided in the specification may be used to supplement the analysis of the design. If a design is embodied in a specific mechanical article, the analysis that the design lacks ornamentality because its appearance is dictated by functional requirements should be supported by reference to utility patents or some other source of information about the function of the design. If the design is embodied in an article that has a more general use, such as a clip, the analysis and explanation as to why the design lacks ornamentality should be detailed and specific. The examiner’s contention that the specific appearance of the claimed design lacks ornamentality may be supported by In re Carletti et al., 328 F.2d 1020, 140 USPQ 653 (CCPA 1964) (a design to be patentable must be “created for the purpose of ornamenting” the article in which it is embodied.). The presence or lack of ornamentality must be made on a case by case basis.

Hidden Design Features Not Prima Facie Evidence of Functionality
Note:
Design features that are hidden during an article's normal use do not automatically prove the design is functional and lack ornamentality.

Knowledge that the article would be hidden during its end use based on the examiner’s experience in a given art or information that may have been submitted in the application itself would not be considered prima facie evidence of the functional nature of the design. See Seiko Epson Corp v. Nu-Kote Int’l Inc., 190 F.3d 1360, 52 USPQ2d 1011 (Fed. Cir. 1999). “Visibility during an article’s ‘normal use’ is not a statutory requirement of § 171, but rather a guideline for courts to employ in determining whether the patented features are ‘ornamental’.” See Larson v. Classic Corp., 683 F. Supp. 1202, 7 USPQ2d 1747 (N.D. Ill. 1988). If there is sufficient evidence to show that a specific design "is clearly intended to be noticed during the process of sale and equally clearly intended to be completely hidden from view in the final use," it is not necessary that a rejection be made under 35 U.S.C. 171. See In re Webb, 916 F.2d 1553, 1558, 16 USPQ2d 1433, 1436 (Fed. Cir. 1990). The mere fact that an article would be hidden during its ultimate end use is not the basis for a rejection under 35 U.S.C. 171, but this information provides additional evidence to be used in support of the contention that the design lacks ornamentality. The only basis for rejecting a claim under 35 U.S.C. 171 as lacking in ornamentality is an evaluation of the design itself in light of additional information, such as that identified above.

Design Must Be Visible During Use to Establish Ornamentality
Note:
Applicant must prove the design is visible at some point between manufacture and use to establish its ornamentality for a design patent claim.

In a rejection of a claim under 35 U.S.C. 171 in which some of the evidentiary basis for the rejection is that the design would be hidden during its end use, the applicant must establish that the “article’s design is a ‘matter of concern’ because of the nature of its visibility at some point between its manufacture or assembly and its ultimate use.” See In re Webb, 916 F.2d 1553, 1558, 16 USPQ2d 1433, 1436 (Fed. Cir. 1990). This concern may be shown by the submission of evidence that the appearance of the article was of concern during its period of commercial life by declarations from prospective/actual customers/users attesting that the ornamentality of the article was of concern to them. Unless applicant is directly involved with the sale of the design or works with users of the design, he or she cannot provide factual evidence as to the reasons for the purchase/selection of the article embodying the design.

Design Must Be Created for Ornamentation
Note:
A design must be created specifically for aesthetic purposes and not as a by-product of functionality to qualify under the ornamental requirements.

An ornamental feature or design has been defined as one which was “created for the purpose of ornamenting” and cannot be the result or “merely a by-product” of functional or mechanical considerations.

It is clear that the ornamentality of the article must be the result of a conscious act by the inventor, as 35 U.S.C. 171 requires that a patent for a design be given only to “whoever invents any new, original, and ornamental design for an article of manufacture.” Therefore, for a design to be ornamental within the requirements of 35 U.S.C. 171, it must be “created for the purpose of ornamenting.” See In re Carletti, 328 F.2d 1020, 1022, 140 USPQ 653, 654 (CCPA 1964).

Design Must Be Created for Ornamenting
Note:
A design patent requires that the ornamental feature be created specifically for aesthetic purposes, not as a by-product of functionality.

An ornamental feature or design has been defined as one which was “created for the purpose of ornamenting” and cannot be the result or “merely a by-product” of functional or mechanical considerations. See In re Carletti, 328 F.2d 1020, 140 USPQ 653, 654 (CCPA 1964); Blisscraft of Hollywood v. United Plastic Co., 189 F. Supp. 333, 337, 127 USPQ 452, 454 (S.D.N.Y. 1960), aff’d, 294 F.2d 694, 131 USPQ 55 (2d Cir. 1961). It is clear that the ornamentality of the article must be the result of a conscious act by the inventor, as 35 U.S.C. 171 requires that a patent for a design be given only to “whoever invents any new, original, and ornamental design for an article of manufacture.” Therefore, for a design to be ornamental within the requirements of 35 U.S.C. 171, it must be “created for the purpose of ornamenting.” See In re Carletti, 328 F.2d 1020, 1022, 140 USPQ 653, 654 (CCPA 1964).

Ornamental vs Functional Features Distinction
Note:
The rule distinguishes between the ornamental design and functional features of an article, ensuring that a design cannot be assumed to lack ornamentality solely because it serves a primary function.

“However, a distinction exists between the functionality of an article or features thereof and the functionality of the particular design of such article or features thereof that perform a function.” See Avia Group International Inc. v. L. A. Gear California Inc., 853 F.2d 1557, 1563, 7 USPQ2d 1548, 1553 (Fed. Cir. 1988). The distinction must be maintained between the ornamental design and the article in which the design is embodied. The design for the article cannot be assumed to lack ornamentality merely because the article of manufacture would seem to be primarily functional.

Visibility During Normal Use Is Not a Statutory Requirement for Ornamentality
Note:
The visibility of patented features during an article's normal use does not determine their ornamental nature; courts use this as a guideline to assess ornamentality.

Knowledge that the article would be hidden during its end use based on the examiner’s experience in a given art or information that may have been submitted in the application itself would not be considered prima facie evidence of the functional nature of the design. See Seiko Epson Corp v. Nu-Kote Int’l Inc., 190 F.3d 1360, 52 USPQ2d 1011 (Fed. Cir. 1999). “Visibility during an article’s ‘normal use’ is not a statutory requirement of § 171, but rather a guideline for courts to employ in determining whether the patented features are ‘ornamental’.” See Larson v. Classic Corp., 683 F. Supp. 1202, 7 USPQ2d 1747 (N.D. Ill. 1988). If there is sufficient evidence to show that a specific design "is clearly intended to be noticed during the process of sale and equally clearly intended to be completely hidden from view in the final use," it is not necessary that a rejection be made under 35 U.S.C. 171. See In re Webb, 916 F.2d 1553, 1558, 16 USPQ2d 1433, 1436 (Fed. Cir. 1990). The mere fact that an article would be hidden during its ultimate end use is not the basis for a rejection under 35 U.S.C. 171, but this information provides additional evidence to be used in support of the contention that the design lacks ornamentality. The only basis for rejecting a claim under 35 U.S.C. 171 as lacking in ornamentality is an evaluation of the design itself in light of additional information, such as that identified above.

Requirement for Prima Facie Showing of Lack of Ornamentality
Note:
An examiner must provide evidence to show that a design lacks ornamentality before rejecting it under 35 U.S.C. 171.

To properly reject a claimed design under 35 U.S.C. 171 on the basis of a lack of ornamentality, an examiner must make a prima facie showing that the claimed design lacks ornamentality and provide a sufficient evidentiary basis for factual assumptions relied upon in such showing. See In re Jung, 637 F.3d 1356, 1362, 98 USPQ2d 1174, 1177 (Fed. Cir. 2011). See, e.g., In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992), (“the examiner bears the initial burden, on review of the prior art or on any other ground, of presenting a prima facie case of unpatentability.”).

Design Must Be Created for Ornamentation
Note:
A design must be created with the purpose of ornamenting an article of manufacture to qualify for a patent under 35 U.S.C. 171.

An ornamental feature or design has been defined as one which was “created for the purpose of ornamenting” and cannot be the result or “merely a by-product” of functional or mechanical considerations. See In re Carletti, 328 F.2d 1020, 140 USPQ 653, 654 (CCPA 1964); Blisscraft of Hollywood v. United Plastic Co., 189 F. Supp. 333, 337, 127 USPQ 452, 454 (S.D.N.Y. 1960), aff’d, 294 F.2d 694, 131 USPQ 55 (2d Cir. 1961).

Evidentiary Basis for Lack of Ornamentality
Note:
The examiner may use various sources to support a lack of ornamentality in design analysis, including the specification and utility patents.

The proper evidentiary basis for a rejection under 35 U.S.C. 171 that a claim is lacking in ornamentality is an evaluation of the appearance of the design itself. The examiner’s knowledge of the art, a reply to a letter of inquiry, a brochure emphasizing the functional/mechanical features of the design, the specification of an analogous utility patent (the applicant’s or another inventor), or information provided in the specification may be used to supplement the analysis of the design. If a design is embodied in a specific mechanical article, the analysis that the design lacks ornamentality because its appearance is dictated by functional requirements should be supported by reference to utility patents or some other source of information about the function of the design. If the design is embodied in an article that has a more general use, such as a clip, the analysis and explanation as to why the design lacks ornamentality should be detailed and specific. The examiner’s contention that the specific appearance of the claimed design lacks ornamentality may be supported by In re Carletti et al., 328 F.2d 1020, 140 USPQ 653 (CCPA 1964) (a design to be patentable must be “created for the purpose of ornamenting” the article in which it is embodied.). The presence or lack of ornamentality must be made on a case by case basis.

Examiner Form Paragraphs

Examiner form paragraphs are standard language that you might see in an Office Action or communication from the USPTO. Examiners have latitude to change the form paragraphs, but you will often see this exact language.

¶ 15.08 ¶ 15.08 Lack of Ornamentality (Article Visible in End Use)

The claim is rejected under 35 U.S.C. 171 as being directed to nonstatutory subject matter in that it lacks ornamentality. To be patentable, a design must be “created for the purpose of ornamenting” the article in which it is embodied. See In re Carletti, 328 F.2d 1020, 140 USPQ 653 (CCPA 1964).

The following evidence establishes a prima facie case of a lack of ornamentality: [1]

Evidence that demonstrates the design is ornamental may be submitted from the applicant in the form of an affidavit or declaration under 37 CFR 1.132 :

(a) stating the ornamental considerations which entered into the design of the article; and

(b) identifying what aspects of the design meet those considerations.

An affidavit or declaration under 37 CFR 1.132 may also be submitted from a representative of the company, which commissioned the design, to establish the ornamentality of the design by stating the motivating factors behind the creation of the design.

Attorney arguments are not a substitute for evidence to establish the ornamentality of the claim. Ex parte Webb , 30 USPQ2d 1064, 1067-68 (Bd. Pat. App. & Inter. 1993).

Examiner Note

In bracket 1, insert source of evidence of lack of ornamentality, for example, a utility patent, a brochure, a response to a letter of inquiry, etc.
