Class 510

CLEANING COMPOSITIONS FOR SOLID SURFACES, AUXILIARY COMPOSITIONS THEREFOR, OR PROCESSES OF PREPARING THE COMPOSITIONS


Class Definition:
This class is an integral part of Class 252, as shown by the position of the box identifying this class in the Class 252 schedule. As such, this class is subject to the Class Definition and Notes of Class 252, except as noted in the box.
(1) STATEMENT OF CLASS SUBJECT MATTER
This class includes the following subject matter, not provided for elsewhere, when a utility set forth below is either (a) claimed or (b) solely disclosed.
(A) CLEANING COMPOSITIONS FOR SOLID SURFACES which are specialized and designed for, or peculiar to, use in cleaning or removing foreign matter from solid surfaces.
(B) AUXILIARY COMPOSITIONS, PER SE, for perfecting the cleaning compositions of this class or for perfecting a cleaning process (e.g. rinse- or dryer-added fabric softener compositions, etc.) for which there is no provision elsewhere.
(C) COMPOSITIONS OF THIS CLASS DEFINED IN TERMS OF SPECIFIC PHYSICAL STRUCTURE (E.G., TABLET, COATED PARTICLE, ETC.) - The lines generally prevailing between the composition classes and the article classes are applicable to Class 510 unless otherwise indicated, with the exception that Class 510 provides for a composition, per se, defined in terms of specific structure, having a utility for Class 510.
(D) PACKAGES of compositions of this class, or other articles which releasably enclose or support such compositions, for which there is no provision elsewhere.
(E) PROCESSES OF PREPARING subject matter of A - D not provided for elsewhere.
(2) CLASSIFICATION GUIDELINES FOR THIS CLASS
(A) In this class, the classification of a composition is based on its primary utility as (a) a cleaning agent or (b) an auxiliary agent for perfecting a cleaning composition or a given stage of a cleaning process.
(1) Within category (a), above, the classification is based on (i) the claimed or solely disclosed utility for cleaning a specific substrate or removing a specific contaminant; or, for all-purpose cleaning compositions, or (ii) the presence of a specified perfecting component; (iii) the physical form of the claimed composition; (iv) the particular process of preparing the composition; and (v) the chemical nature of the components of the composition.
(2) Within category (b) of section A, above, the classification is based on (i) the claimed or solely disclosed utility as a perfecting component for a cleaning composition or as an auxiliary composition for cleaning, with further placement according to criteria (ii), (iii), and (v) of section A, (1), above.
(3) Within category (v) of section A (1), above, the chemical structure of the components of a composition disclosed as having a utility set forth in section A (1), above, is used as the primary basis of classification. Processes of using compositions or compounds, per se, and processes of making the compositions, not provided for elsewhere, are classified in the first appearing subclass providing for the particular component being employed or prepared.
(B) The rule followed in classifying a patent having separate claims to several species of a given ingredient which fall into different subclasses is that the patent is placed as an original in the first appearing subclass providing for the claimed subject matter and cross-referenced to the appropriate lower subclass(es). Where there are one or more indents under the generic subclass and one of the claimed species is not provided for specifically by any of these indents the patent is placed as original in the generic subclass, since this is the first appearing subclass providing for said individually claimed species. In classifying a patent containing Markush type claims (e.g., "group consisting of X and Y") and no species claims, the original patent is placed in the first appearing subclass providing for the species (members) in the Markush group. If, in addition to the Markush group, there are species claims, the first cited rule, governing a patent having separate species claims, is followed. The same rules apply to subject matter within the meaning of categories (i)-(iv) of section A, 1, above, by analogy with the "species" concept.
(C) Patents claiming subject matter coming within the Special Subclasses 101 through 107 have been classified on the basis of the claimed or disclosed function and the chemical structure of the active component (i.e., fragrance or aroma enhancer), and include compositions which otherwise would fall within subclasses 108 through 537 as originals.
(D) In determining the utility of a composition recited in broad terms (e.g., "a cleaning composition comprising," "a fabric softener composition comprising," etc.), use is made of the specific utility recited in any nominal method-of-use claims to determine placement of the patent within the categories of (a)(i) or (b)(i) of section A, above (e.g., the recitation of "a process of defluxing a printed circuit" or "a process of softening a fabric in the rinse cycle of an automatic washer" would place each patent in subclasses 175+ and 521+, respectively).
(E) Mere presence of a surfactant component is insufficient for placement of a patent in subclasses 108 through 512 of this class, since surface-active agents are used in minor amounts as emulsifying, suspending, dispersing, etc., agents in many other compositions, such as bleaches, fabric softeners, etc. The placement of such a patent is determined by the ultimate utility of the claimed composition.
(F) A patent claiming a cleaning or auxiliary composition without specifying its physical form has been placed as an original in the first subclass providing for the claimed composition as if a structureless powder were recited in the claims, and crossed into appropriate subclasses providing for any other disclosed or exemplified physical forms (e.g., liquid, tablet, etc.).

LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
(A) GENERAL CLASS LINES
(1) COMPOUND CLASSES
a. Where a patent claims a Class 510 utility in nominal terminology only (e.g., "A process of producing a biodegradable detergent compound") and there are no claims to a Class 510 method of use or a true mixture, the original has been placed with the compound claimed.
(b) Where a patent claims a composition wherein, in addition to a compound, (i) another ingredient is recited, however broadly, or (ii) proportions are recited, the original has been placed in Class 510. Some examples of claims using broad terminology and included herewith are: "A cleaning composition comprising a surfactant of the formula," "with a detergent builder," "A cleaning composition comprising 1 to 5% of compound X," etc.
(2) COMPOSITION CLASSES
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.
(3) PROCESS OF USE CLASSES
The following general lines exist between Class 510 and other classes providing for cleaning processes or containing patents wherein the claims recite a process of cleaning a solid substrate as provided for in that class.
(a) Where a patent claims a cleaning composition and a nominal process of using the composition, the original has been placed with the claimed composition. Some examples of nominal terminology are: "applying the composition and removing it {by rinsing, wiping, etc.}," "immersing the article to be cleaned in a cleaning bath containing the composition," etc.
(b) Where a cleaning composition, per se, is not claimed or where the claimed cleaning process involves significant process steps in using a claimed composition, the original has been placed with the claimed cleaning process.

A surfactant molecule contains a hydrophobic (water-repelling) portion which is frequently an alkyl radical having a straight chain of eight or more carbons, and a hydrophilic (water-attracting) portion. For purposes of this class, the broad categories of surfactants are based on the nature of the hydrophilic portion of the molecule.
(1) Note. An anionic (anion-active) surfactant, referred to in the schedule as "anionically substituted," includes a hydrophilic portion which is most commonly a water-soluble salt of a carboxylic or sulfonic acid, or of a long-chain alcohol ester of sulfuric, phosphoric, or phosphonic acid (e.g., sodium higher alkyl sulfonate, etc.).

(3) Note. A nonionic surfactant includes a hydrophilic portion which commonly is a poly(ethylene oxide) moiety (i.e., polyether chain) attached to a hydrophobic portion which may be nonpolar or have a lower degree of polarity than the hydrophilic part, such as poly(propylene oxide), higher alkyl, etc.
(4) Note. A zwitterionic, amphoteric, or ampholytic surfactant includes both an anionic and a cationic portion connected by a covalent bond, usually indirect (e.g., betaines, amino acids, etc.).
(5) Note. Semipolar nonionic surfactants include water-soluble amine and phosphine oxides and sulfoxides.
(6) Note. Soap, for purposes of this class, is an alkali metal, ammonium or organic base salt of an unsubstituted or hydroxy-substituted, saturated or unsaturated higher fatty acid, or of rosin (abietic) acid, or of mixtures of any of these acids. These salts are water-soluble and are considered to be anionic surfactants.
