SUBCLASSES

[List of Patents for class 512 subclass 1]    1PERFUME COMPOSITIONS
 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 LINES WITH OTHER CLASSES AND WITHIN THIS CLASS, subsection COMPOSITION CLASS SUPERIORITY, which includes a hierarchical ORDER OF SUPERIORITY FOR COMPOSITION CLASSES.
(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.
