This is an appeal from a decision of the Trademark Trial and Appeal Board1 refusing to register2 on the Principal Register a portion of the under-rim configuration shown in the drawing below as a trademark for "China dishware."3

NOTE: OPINION CONTAINING TABLE OR OTHER DATA THAT IS NOT VIEWABLE China dishware incorporating such ribs was the subject of a U. S. utility patent 2,178,274, issued October 31, 1939 to R. Ratner. The patent was assigned to the appellant herein (or its predecessor), and that patent expired in 1956. The patent was directed to the use of a median rib as above shown on the under-surface of a tableware article such as a plate. The patent states:

* * * In virtue of its behavior in protecting the article against chipping, cracking and breaking as the result of vibratory stresses from impact-shocks received by the article, I call this rib the vibration-throttling rib. * * *

The patentee notes that pedestal ribs and perimetral ribs were then conventional, the former "allowing the articles to be stacked without extended face to face contact while in the kiln," and thus are "important in aiding manufacture of the article * * *." Although the perimetral rib had been used "with the idea of strengthening the flange * * *" of tableware, the patentee discovered the lifetime of such ware was shortened rather than prolonged.4 The patentee teaches that:

Whether or not the perimetral rib is present, the vibration-throttling rib of the present invention has been found by actual test to act in precisely the way it should act to justify its designation as a vibration-throttling element. * * *

A second "important" advantage taught by the patentee to arise from the use of the ribs is that "convenient and safe handling of the articles is made possible when it is grasped in one hand only," because the space between the ribs affords "a finger stall or seat for naturally accommodating a finger of an adult's hand." The claims were directed to the middle rib, either with the pedestal rib or with both the pedestal and perimetral ribs.5

The examiner in refusing to register the "representation of goods" distinguished between containers that may serve as a trademark for the contents therein, and a "representation of goods themselves purporting to be trademarks for the same goods * * *." That point, however, was not the reason for final refusal to register below, nor is it the basis of our decision here. The basic reason for refusal, as stated by the examiner, was that the rib configuration is a functional feature:

* * * This configuration of goods is said to be a scientifically designed molded roll that reinforces the underside of the rim at its weakest structural point. The representation of this "exclusive patented double roll construction" is firmly believed not to be a trademark. The trademark is the name Rim-Rol,6 which applicant has given to this utilitarian feature of the goods, but the construction feature of the goods themselves is not a trademark as defined in Section 45 of the Trademark Statute, and therefore, it is not a mark capable of distinguishing the goods as required by Section 2 of the Trademark Statute. * * *

The refusal to register was affirmed by a majority of the board (there was also a concurring minority opinion),7 on the ground that the subject matter under consideration "is incapable of distinguishing applicant's goods from the goods of others because it is merely a functional feature of a product on which the patent has expired."

Thus this appeal presents the issue whether the preamble of section 2 (15 U.S.C. § 1052) and the definition of trademarks under section 45 (15 U.S.C. § 1127) preclude the registration on the Principal Register of the present three-dimensional configuration with its functional aspects. No section 2(f) issue is presented.

Appellant contends that the under-rim configuration falls within the statutory definition of a trademark, section 45, as it "includes any * * * symbol, or device * * *," and that the listing of configuration of goods in section 23 (15 U.S.C. § 1091) does not preclude registration on the Principal Register. Appellant also argues that section 2 of the 1946 Act is mandatory, that no trademark shall be refused registration "on account of its nature * * *" except for those grounds specifically set forth in subsections (a) to (e) under section 2, none of which include functionality. Thus appellant states:

All of the reasons advanced by the Examiner and the Board boil down to refusals to register appellant's mark because (a) of its mechanically functional nature or, (b) when used on ware also having a foot rib, such footed ware identified by appellant's mark was once patented. None of these "natures" of appellant's mark are included in the exceptions recited in sub-sections (a) to (e) of Section 2 of the Act. The decision below, accordingly, amounts to an attempt to amend the statutory mandate, by administrative decision, by adding "non-patented or non-patentable functional marks" as an additional exception to those now listed in subsections of Section 2 of the Act and/or further qualifying the present recital in the Section 45 definition of a trademark so that "any * * * symbol or device" should read "any * * * unpatentable, nonfunctional symbol or device."

Regarding the functionality of the under-rim configuration appellant's position is:

* * * Admittedly applicant's rim configuration was selected to function well as a vibration dampening configuration and to aid the gripping of the ware — while also serving as a distinctive identification. * * *

* * * * * *

* * * it should be pointed out that appellant in no way contends that its mark is non-functional; rather, if mechanical functionality is properly considered at all in determining a trademark's registrability under the 1946 Act, such mechanical functionality of applicant's device is not so non-arbitrary as to impair its obvious function as a distinctive identification of appellant's ware and, therefore, its registrability.

The distinction last quoted represents appellant's attempt to bring the instant under-rim configuration within the class of "shapes which can be monopolized because they are of such an arbitrary nature that the law does not recognize a right in the public to copy them, even if some incidental function is associated with them," In re Deister Concentrator Co., 289 F.2d 496, 48 CCPA 952, 965. By appellant's reading, the Deister case would permit the registration of a functional "symbol, or device" that is "not so non-arbitrary as to impair its obvious function as a distinctive identification of appellant's ware and, therefore, its registrability." We do not so read the Deister case, since that reading changes "incidental function" as not barring registration, to: incidental identification as mandatory of registration. We hold the present case to be controlled by the principles of law in Deister, and in In re Shakespeare Co., 289 F.2d 506, 48 CCPA 969. The under-rim configuration here is unregistrable on the Principal Register since it is functional and in essence utilitarian.

It is our view that the expired utility patent is adequate evidence that the under-rim configuration here sought to be registered is indeed functional. We do not find the board to have erred in rejecting the contention that the present configuration is registrable because its functionality is so incidental as to be "arbitrary" or a mere design. All the evidence points the other way. Appellant's arguments are futile "attempts to reduce it [functionality] to a de minimis status," Deister, supra, 289 F.2d at 504, 48 CCPA at 967.

We think that the 1946 Act is premised on the idea that only nonfunctional configurations may be registrable thereunder. As stated in truism (4) of the Deister case, 289 F.2d at 502, 48 CCPA at 963:

(4) A feature dictated solely by "functional" (utilitarian) considerations may not be protected as a trademark; but mere possession of a function (utility) is not sufficient reason to deny protection.

Rather than adding an exception to section 2 or amending section 45, we are of the view that the terms of the Act provide for the result here. In the absence of other valid patent claims, a feature that is the subject of a utility patent goes into the public domain when the patent expires, Kellogg Co. v. National Biscuit Co., 305 U.S. 111, 120-122, 59 S. Ct. 109, 83 L. Ed. 73 (1938); Singer Mfg. Co. v. June Mfg. Co., 163 U.S. 169, 185, 16 S. Ct. 1002, 41 L. Ed. 118 (1896). Such a feature, being free to be used by any person, thus cannot be a "trademark [a "symbol, or device," section 45] by which the goods of the applicant may be distinguished," section 2, 15 U.S.C. § 1052. [Emphasis added.] Similarly, the definition of a trademark under section 45, 15 U.S.C. § 1127, requires that the symbol or device "identify * * * and distinguish * * *" the goods of a manufacturer or merchant from those manufactured or sold by others. We think it the broad policy of the law that a functional feature cannot satisfy the requirements of those words.

As this court stated in the Deister case, 289 F.2d 505, 48 CCPA at 968:

It seems to us that this case perfectly exemplifies what we mean by a functional or utilitarian shape which is incapable of acquiring a legally recognizable "secondary meaning" or of becoming an enforceable trademark for the simple reason that, absent patent protection, the public has the right to copy the shape and enjoy its advantages. * * *

Although the patent claimed the middle or vibration-throttling rib in combination with a pedestal or foot rib, the result is no different where the configuration is present on a plate having no pedestal rib. The patent is taken only as some evidence, here conclusive, that the involved under-rim configuration is indeed functional. Thus the result here is not dependent on the precise scope of the patent claims.

We do not find In re Mogen David Wine Corp., 328 F.2d 925, 51 CCPA 1260, or In re Minnesota Mining & Mfg. Co., 335 F.2d 836, 51 CCPA 1546, to be apposite to this case. The Mogen David case involved the design or non-functional configuration of a container for goods and thus cannot stand as precedent on the functionality issue here. The Minnesota Mining case involved an arbitrary, non-functional configuration of goods. So far as is pertinent to registrability for federal trademark protection, we believe Sears, Roebuck & Co. v. Stiffel Co., 376 U.S. 225, 84 S. Ct. 784, 11 L. Ed. 2d 661 and Compco Corp. v. Day-Brite Lighting, Inc., 376 U.S. 234, 84 S. Ct. 779, 11 L. Ed. 2d 669, to be consistent with the result reached herein.

For the foregoing reasons the decision of the board is affirmed.

Affirmed.

SMITH, Judge, concurs in the result.
