2 FUENTE MARKETING LTD. v. VAPOROUS TECHNOLOGIES, LLC

Fuente Marketing Ltd. appeals the decision of the United States Trademark Trial and Appeal Board dismissing its opposition to a trademark application filed by Vaporous Technologies, LLC. The Board dismissed Fuente’s opposition on the ground that there was no likelihood of confusion between Vaporous’s applied-for mark and Fuente’s registered X marks. We affirm.

I

Fuente Marketing Ltd. (Fuente) and Vaporous Technologies , LLC (Vaporous) both offer smoking-related products . Fuente is a family-owned-and-operated company that sells premium hand-rolled cigars made with tobacco grown in the Dominican Republic. Fuente owns two standard character trademarks for the letter X for use in connection with cigars, ashtrays not of precious metal, cigar cutters, and lighters not of precious metal. See X, Registration No. 3,254,146; X, Registration No. 3,285,314. As it has registered standard character marks, Fuente is entitled to depictions of its X marks without limitation as to font style, size, or color. See Citigroup Inc. v. Cap. City Bank Grp., Inc., 637 F.3d 1344, 1353 (Fed. Cir. 2011).

Vaporous designs and manufactures oral vaporizers (colloquially, vapes), which are battery-powered devices that simulate smoking by heating a concentrate into an aerosol the user inhales. On September 18, 2020, Vaporous filed an intent-to-use application, seeking to register the following mark:

for use on or in connection with the following goods in International Class 34:

Oral vaporizers for smoking purposes; oral vaporizers for smoking purposes for use with liquid nicotine solutions; oral vaporizers for smoking purposes for use with electronic cigarette liquid (e-

liquid); oral vaporizers for smoking purposes for use with oils, waxes and isolates containing CBD being solely derived from hemp with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis; oral vaporizers for smoking purposes for use with oils waxes and isolates having a tetrahydrocannabinol concentration of more than 0.3 percent on a dry weight basis; all of the foregoing goods are exclusively for use with tobacco products, cannabis products solely derived from hemp with a delta-9 tetrahydrocannabinol (THC) concentration of not more than 0.3 percent on a dry weight basis, and CBD products solely derived from hemp with a delta-9 tetrahydrocannabinol (THC) concentration of not more than 0.3 percent on a dry weight basis[.]

U.S. Trademark Application Serial No. 90/192,180 (filed Sep. 18, 2020). Fuente opposed Vaporous’s application, alleging a likelihood of confusion between the mark and its own standard character X marks.1 See 15 U.S.C. § 1052(d). During the opposition proceedings, the parties filed a stipulation addressing evidence and facts relevant to the likelihood of confusion analysis. See J.A. 130. The parties made the following stipulation of fact: “Vaporous’s X Dot Mark ‘consists of an abstract stick figure consisting of two diagonal intersecting lines in the shape of a wide stylized letter “X” and a shaded circle above the letter “X.”’” J.A. 133.

In December 2023, the Trademark Trial and Appeal Board (Board) dismissed Fuente’s opposition after

1 Fuente also opposed Vaporous’s application on grounds that the mark was likely to be confused with Fuente’s family of eighteen registered marks encompassing the letter X. But the Trademark Trial and Appeal Board concluded no such family of marks exists, and Fuente does not challenge that finding on appeal.

determining there was no likelihood of confusion between Vaporous’s mark and Fuente’s X marks. Fuente Mktg. Ltd. v. Vaporous Techs., LLC, No. 91270800, 2023 WL 11758750, at *18 (T.T.A.B. Dec. 14, 2023) (Decision). The Board assessed the existence of a likelihood of confusion by considering the factors set out in In re E.I. DuPont DeNemours & Co., 476 F.2d 1357, 1361 (C.C.P.A. 1973). Specifically, the Board determined that the lack of actual confusion and the strength of Fuente’s marks were neutral; the goods, channels of trade, and classes of purchasers were related or overlapped, favoring a likelihood of confusion ; and the dissimilarity of the marks weighed against a likelihood of confusion. Decision, 2023 WL 11758750, at *18. The Board concluded that, although many factors weighed in favor of a likelihood of confusion, the parties’ marks create distinct commercial impressions and are sufficiently dissimilar to negate any likelihood of confusion. The Board thus dismissed Fuente’s opposition, and Fuente timely appealed. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(4)(B).

Under the Lanham Act, a mark may be refused registration on the principal register if it is “likely, when used on or in connection with the goods of the applicant, to cause confusion” with another’s mark. 15 U.S.C. § 1052(d). “Likelihood of confusion is a question of law with underlying factual findings made pursuant to the DuPont factors.” StonCor Grp., Inc. v. Specialty Coatings, Inc., 759 F.3d 1327, 1331 (Fed. Cir. 2014). We review the Board’s factual findings on each relevant DuPont factor for substantial evidence but its ultimate legal conclusion regarding likelihood of confusion de novo. Id. Substantial evidence is “more than a mere scintilla”; it is “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Consol. Edison Co. of N.Y. v. NLRB, 305 U.S. 197, 229 (1938).

FUENTE MARKETING LTD. v. VAPOROUS TECHNOLOGIES, LLC 5

On appeal, Fuente challenges the Board’s analysis of DuPont factors one and five—respectively, the similarity of the marks and the fame of Fuente’s registered X marks. Fuente also challenges the Board’s overall weighing of the DuPont factors.2 Vaporous counters, primarily contesting the Board’s analysis of DuPont factors three and four, which consider the similarity between the parties’ trade channels and the relative sophistication of each party’s consumers.

The first DuPont factor assesses the “similarity or dissimilarity of the marks in their entireties as to appearance, sound, connotation and commercial impression.” DuPont, 476 F.2d at 1361. “The proper test is not a side-by-side comparison of the marks, but instead whether the marks are sufficiently similar in terms of their commercial impression such that persons who encounter the marks would be likely to assume a connection between the parties.” Coach Servs., Inc. v. Triumph Learning LLC, 668 F.3d 1356, 1368 (Fed. Cir. 2012) (cleaned up). The Board found that DuPont factor one decisively weighed against a likelihood of confusion because consumers would perceive Vaporous ’s mark as a stick figure, rather than the letter X. And because a stick figure has no pronunciation, unlike the letter X, the parties’ marks differed in sound. The Board then focused on the visual differences between the marks, ultimately finding that the “dissimilarity between the
