1202.13 Scent, Fragrance, or Flavor
Scent. The scent of a product may be registrable if it is used in a nonfunctional manner. See In re Clarke, 17 USPQ2d 1238, 1239-40 (TTAB 1990) (holding that the scent of plumeria blossoms functioned as a mark for "sewing thread and embroidery yarn"). Scents that serve a utilitarian purpose, such as the scent of perfume or an air freshener, are functional and not registrable. See TMEP §§1202.02(a)-1202.02(a)(viii) regarding functionality. When a scent is not functional, it may be registered on the Principal Register under §2(f), or on the Supplemental Register if appropriate. The amount of evidence required to establish that a scent or fragrance functions as a mark is substantial. Cf. In re Owens-Corning Fiberglas Corp., 774 F.2d 1116, 227 USPQ 417 (Fed. Cir. 1985) (requiring concrete evidence that the mark is perceived as a mark to establish distinctiveness).
Flavor. Just as with a scent or fragrance, a flavor can never be inherently distinctive because it is generally seen as a characteristic of the goods. In re N.V. Organon, 79 USPQ2d 1639 (TTAB 2006) (affirming refusal to register "an orange flavor" for "pharmaceuticals for human use, namely, antidepressants in quick-dissolving tablets and pills," on the grounds that the proposed mark was functional under §2(e)(5) and failed to function as a mark within the meaning of §§1, 2, and 45 of the Trademark Act). The Board has observed that it is unclear how a flavor could function as a source indicator because flavor or taste generally performs a utilitarian function and consumers generally have no access to a product’s flavor or taste prior to purchase. Id. at 1650-51. Thus, an application to register a flavor "requires a substantial showing of acquired distinctiveness." Id. at 1650.
