| | 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. |

Compositions for Solid Surfaces, Auxiliary Compositions Therefor,
or Processes of Preparing the Compositions,
subclasses 101 through 107for 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,
subclass 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." |
