DEFINITION

Classification: 585/1

PRODUCT BLEND, E.G., COMPOSITION, ETC., OR BLENDING PROCESS, PER SE:

(under the class definition) Subject matter which comprises an intentional mixture of a hydrocarbon with another material which may be a hydrocarbon or a nonhydrocarbon, and process for making such a mixture which does not involve any claimed chemical reaction or purification step.

(1) Note. By "intentional" it is meant that at least one of the different components of the mixture is present because of a desired effect, not merely because the mixture is the

normal result of a synthesis process, as in polymerization, or is found as such in nature. Reaction product mixtures, per se, are classified in subclasses 16+.

(2) Note. 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. Where classification is called for in different main classes, based upon the components of the composition or claims pertaining to a plurality of use, properties, or functions, a patent is assigned as an original to that class or portion of a class coming first in the list given in the class definition, (5) Note of Class 252. This superiority list is not intended as a complete list and will be expanded or added to as the relationship between other classes containing compositions is determined.

The enumeration of classes below, in general, follows the priority list of Class 252 and covers some additional classes. Thus, this enumeration is not authoritative insofar as priority of classes is concerned. The definitions of these classes should be studied to determine the proper placement of patents therein.

Class 504, Plant Protecting and Regulating Compositions, subclasses 116+ provide for plant growth regulating compositions; and subclasses 101+ provide for a fertilizer containing an insecticide, fungicide, or deodorant.

Class 424 provides for drug, bio-affecting and body treating compositions. A material, composition, or compound containing a Class 424 composition to preserve the material, composition, or compound itself from biological attack generally is classified with the material, composition, or compound. Residual methods for preserving, disinfecting, or sterilizing are in Class 422.

Class 426 provides for foods, beverages, and other edible compositions and certain edible articles and stock materials. Class 71, provides for fertilizers.

Class 208, subclasses 14+ provide for composition made up exclusively of components derived from mineral oil (petroleum) and certain other feedstocks, as explained in the class definition of Class 208. Each such component may be an entire "crude oil", a complex distillate or fraction thereof, a fraction formed by some chemical conversion (e.g., cracking, reforming), solvent extraction, or other treatment provided for in Class 208. Where, in addition to one or more mineral oil-derived components, the composition contains a single definite hydrocarbon or a mixture of hydrocarbons not of mineral origin, the composition is classified in this

class (585). Exemplary of such compositions for this class are gasoline admixed with benzol, hydrocarbons formed by reduction of the alcohol and aldehyde fraction produced by the hydrogenation of carbon monoxide, naphthalene, isopentane, alkylated benzene, disobutylene, anthracene, etc. A process of separating the mineral oil into fractions, one of which may be definite hydrocarbon, followed by treating the various fractions to convert them chemically and then blending two or more fractions to form the final fuel is classified in Class 208, Mineral Oils: Processes and Products, unless there is present a claim to the composition, per se, which recites the blend of a mineral oil and a definite hydrocarbon.

Class 149 provides for explosive and thermic compositions and charges. Subclass 87 provides for such compositions containing free metal or metal hydride with a hydrocarbon.

Class 508, particularly subclasses 110+, provides for lubricants which contain nonhydrocarbons. Lubricants which are mixtures of hydrocarbons (except for solid synthetic hydrocarbon polymers) are in this Class 585 or in Class 208. Lubricants which contain solid synthetic hydrocarbon polymers are classified in Class 508.

Classes 44 and 48 provide for fuels which contain nonhydrocarbon components. Fuels which are all hydrocarbon are in this class (585) or in Class 208.

Class 148 provides in subclasses 240+ and 22+ for certain compositions for treating solid metal. Subclass 25 provides for oleaginous fluxing compositions.

Class 75, Specialized Metallurgical Processes, Compositions for Use Therein, Consolidated Metal Powder Metal Powder Compositions, and Loose Metal Particulate Mixtures, subclasses 228+ for sintered metal powder compositions and subclasses 95 and 257 for certain additives for molten metal.

Class 430, Radiation Imagery Chemistry: Process, Composition, or Product, Thereof for compositions and articles defined in terms of their chemical composition which are useful in forming images by the impingement of radiation thereon, e.g., photography, etc.

Class 252 provides in subclasses other than those listed above or below for special utility compositions.

Class 106 provides for a composition which is in fluent or solid noncoherent form and which is adapted for coating or impregnating and for change to a less fluent or a solid coherent form by setting (e.g., concrete, plaster, etc.), chemical reaction, removal of solvent, solidification from molten state, etc., and fillers and pigments for its own and some other compositions. Subclass 11 provides for a hydrocarbon-containing polish; subclass 239 provides for a

coating or plastic composition containing a fatty oil and a hydrocarbon; and subclass 285 for such composition containing a hydrocarbon. Class 51 provides for abrading compositions.

Classes 520+ provide for a synthetic resin (spinnable, film forming, etc.) and Class 260, subclasses 709+ provide for a vulcanizable natural hydrocarbon gum (e.g., rubber).

Class 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 hierarchically superior provision in the USPC for the specifically claimed art.

Class 252, subclasses 299.01+, 363.5, 367.1, 372+, and 378 provide for compositions on a nonfunctional basis.

Class 423 provides for inorganic compounds; and subclasses 265+ provide for compositions having an inorganic compound and an agent which improves the general utility of the compound.

Class 260 and its daughter Classes 530-570 provide for an organic compound containing more than carbon and hydrogen and such compound blended with an agent which improves the general utility of the compound.

302+, for a process in which different hydrocarbon components of a composition are separately synthesized and then blended.
