Classification: 512/1

Perfume Compositions intended to impart a pleasant odor, scent or aroma, processes of making or using a perfume composition.

(1) Note. Perfume compositions usually include an active ingredient or enhancer and one or more adjuvants such as extenders, antioxidants, fixatives, etc. Subclasses 2 and 3 are based on the active or enhancing organoleptic ingredient. An active ingredient is a compound which imparts the aroma to the perfume compositions or enhances or augments the aroma of an existing perfume composition. Fixatives and extenders are not considered to be active ingredients; an fixative slow down the rate of evaporation of a perfume by reducing the volatility, and an extender increases the volume of the perfume composition without diluting the aroma.

(2) Note. Processes of extracting essential oils for use in perfumes from animal or plant sources are provided for here.

(3) Note. Processes for the preparation of an odorant compound or odorant mixture that include a fermentation step or the use of an enzyme will be classified elsewhere.

(4) Note. The perfume composition may be intended for application to a living body, clothing, are objects, etc. For example, a flower fragrance may be applied to a person, a pine scent to a Christmas tree, etc.

(5) Note. A patent having a claim to a perfume composition and a claim to an article or a composition having another utility in combination with the perfume composition is classified with the article or other composition, e.g., a perfumed detergent is classified with detergents.

The rules for determining Class placement of the Original Reference (OR) for claimed chemical compositions are set forth in the Class Definition of Class 252 in the section


(6) Note. A claim to a perfume composition which includes a specified organoleptic compound of the composition is specified. However, a compound, per se, is classified in a compound class regardless of the claimed utility. (7) Note. A process of utilizing a compound as a perfume is classified here with perfume compositions.

(8) Note. Plant extracts and essential oils of unknown constitution which are disclosed as essences or odoriferous substances will be considered perfumes compositions even when they are from a single source provided no superior use is set forth.

(9) Note. Broad terms such as "perfume" or "perfume oil" stated to be ingredients in cosmetics, etc., are not enough to warrant cross-referencing to perfume compositions. Further, it is unnecessary to cross-reference patents which disclose an article combined with an old or traditional perfume such as a detergent which has an old essence like lavender oil therein should not be cross-referenced to this class.


2, Apparel,

171.2, for a head covering with means to treat body fluids, e.g., perspiration, etc.

422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing,

5, for a process where an offensive odor is destroyed or masked.

424, and 514, Drug, Bio-Affecting and body Treating Compositions, appropriate subclass for a pharmaceutical, disinfecting, cosmetic or body treating composition that includes a perfume compound or composition.

426, Food or Edible Material: Processes, Compositions, and Products,

651, for a food composition with an essential oil and subclass 655 for an animal or plant extract having Class 426 utility.

434, Education and Demonstration, 377, for a process of demonstrating or exhibiting a perfume product.

435, Chemistry: Molecular Biology and Microbiology, appropriate subclass for a process of preparing an odorant compound or odorant composition that includes a fermentation step or utilizes an enzyme.

510, Cleaning Compositions for Solid Surfaces, Auxiliary Compositions Therefor, or Processes of Preparing the Compositions,

101, 107 for perfume-containing cleaning compositions or auxiliary compositions for cleaning, such as rinse-added fabric softeners, dryer sheets, etc.

516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for subject matter relating to: colloid systems (such as sols*, emulsions, dispersions, foams, aerosols, smokes, gels, or pastes) or wetting agents (such as leveling, penetrating, or spreading); subcombination compositions of colloid systems containing at least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems; compositions and subcombination compositions specialized and designed for or peculiar to use in breaking (resolving) or inhibiting colloid systems; processes of making the compositions or systems of the class; processes of breaking (resolving) or inhibiting colloid systems; in each instance, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art.

523, Synthetic Resins or Natural Rubbers,

102, for composition of a synthetic resin and a perfume wherein the perfume is an integral component of the synthetic resin, e.g., resins with perfume compositions incorporated therein and whose sole purpose is to destroy the natural unpleasant smell of the resin.

532, through 570, Organic Compounds, for a compound disclosed as a perfume or as an organoleptic ingredient in a perfume composition. See Class 532 for definitions of chemical terms used in Class 512 such as "acyclic, alicyclic and polycyclo ring system."
