CLASS 106,	COMPOSITIONS: COATING OR PLASTIC
Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This class is the broad generic class for:

(1) Coating, impregnating or plastic compositions, especially those which set or harden to retain a given shape. Most of the compositions herein found are those which are capable of undergoing a change from a fluent to a nonfluent condition, or from a solid noncoherent form to a solid coherent form, which changes may be effected in any or more of the following ways:

(a) By setting, e.g., concrete;

(b) By chemical reaction or conversion, e.g., viscose;

(c) By removal of solvents or vehicles, e.g., lacquers;

(d) By solidification from a molten state, e.g., asphalt or sulfur.

This class takes all such compositions unless more specifically provided for in other main classes, for which see the notes below under the heading "Coating or Plastic Compositions Elsewhere Classified".

The term "coating" is used throughout the definitions and notes of this class to include "impregnating".

(2) Materials or ingredients, not in themselves coating, impregnating or plastic compositions which are for use in such compositions and for which there is no provision elsewhere. Fillers or pigments for use in rubber, synthetic resins or paper are also included in this class.

(3) The line followed between sections 1 and 2 is that patents broadly claiming coating or plastic compositions, wherein the only ingredients named do not by themselves form coating or plastic compositions, are classified in the appropriate subclasses under the heading "Materials or Ingredients", unless the coating or plastic composition has a characteristic or property specifically provided for above. Thus "a paint comprising a specific pigment" is classified on the basis of the pigment because paints as such are not provided for; however, "an ink comprising a specific pigment" would be placed under "Inks" since inks are provided for as such.

(4) This class takes processes for preparing or making the compositions, materials, or ingredients classified herein, which processes are classified with the corresponding composition, material or ingredient. It does not, however, include processes which are clearly distinct from the composition, material or ingredient, and which are more specifically provided for elsewhere. See the appropriate notes below for the lines with the pertinent process classes.

(5) This class does not include patents which are limited to apparatus only, for which see the appropriate apparatus classes. Patents containing a claim to a composition and/or process of preparing same within this class and a claim to apparatus employed in the preparation of the composition are classified on the basis of the composition or process and cross-referenced to the appropriate apparatus class.

NOTES

It is the present office policy to classify article patents wherein the claims mention the article by name only and define the same only in terms of the composition or material of which it is composed, in the appropriate composition or material class. The collection of these patents and reclassification thereof into the composition or material classes is under way, and as a corollary thereto, patents claiming a composition or material for an art use heretofore classified in the art classes are also being transferred to the appropriate composition or material class. The subsequent notes indicate the extent of this work as of June 1953 and as the remaining use classes are inspected, the article and use patents will be transferred into the appropriate composition or material class.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

ARTICLES DEFINED BY COMPOSITION.

(A) The line in general between this class and the article classes is as follows: Where there are claims to the composition and claims to articles made therefrom, mentioned by name only with no inclusion of structure and defined only in terms of the composition, such patents are classified as originals in the appropriate composition subclasses of this class (106). Patents wherein all the claims are limited to a named article, mentioned by name only with no inclusion of structure and defined only in terms of the composition, are also classified as originals in this class except as noted in "B" below. Where there is claimed significant structure of the article, the patent is classified in the appropriate class providing for the same whether or not there is also present a claim to the composition (see Note C, below).

(B) See the References to Other Classes, below, for named articles defined only by compositions. Some of the article classes also provide for the composition, per se, when specialized for the article classified therein and these classes are indicated in the succeeding references to the article class and in the notes under the section "Coating or Plastic Compositions Elsewhere Classified".

(C) See References to Other Classes, below, for named articles wherein there is claimed significant structure of the article whether or not there are claims to the composition of which the article is composed:

COATING OR PLASTIC COMPOSITIONS ELSEWHERE CLASSIFIED.

(A) 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.

(1) Compositions are in general placed in the appropriate composition class whether or not they are claimed broadly or specifically as specialized for a use, property, or function provided for in some other main class, except as noted below under B.

(2) Compositions which are disclosed as having a plurality of uses, properties or functions provided for in different main classes and only a single use, property or function is claimed, are placed in the composition providing for such claimed use, property or function and cross-referenced to other classes for disclosed uses, properties or functions when desirable.

(3) A list of superiority of composition classes appears in the main class definition of Class 252, Compositions, Lines With Other Classes. This note in Class 252 explains classification of a generic composition with several disclosed uses.

The superiority list below is not intended as a complete list and will be expanded or added to as the relationship between other classes containing compositions and the above listed classes is determined.

71, Chemistry: Fertilizers.

149, Explosive and Thermic Compositions or Charges.

44, Fuel and Related Compositions.

148, Metal Treatment.

508, Solid Anti-Friction Devices, Materials Therefor, Lubricant or Separant Compositions for Moving Solid Surfaces, and Miscellaneous Mineral Oil Compositions.

451, Abrading.

(B) For compositions elsewhere classified, see References to Other Classes, below.

MATERIAL OR INGREDIENTS.

See References to Other Classes, below, identified as material or ingredients classes.

PROCESSES OF PREPARING COMPOSITIONS.

(A) The character of compositions included within Class 106 is such that they are generally capable of being prepared in molds or on surfaces. Where the locus of the preparation is merely incidental to the making of the composition, and no significant molding or coating step is claimed, such processes are classified with the composition in this class (106).

(B) See References to Other Classes identified as for processes which include the preparation of coating or plastic compositions.

(Named articles defined only by compositions.)
252,	Compositions,   the generic class for compositions of matter. (a) Where a use, property or function provided for in Class 252 is claimed, the composition belongs in Class 252. See the notes to the main class definition of Class 252 for references to other classes having nonplastic or noncoating compositions. (b) See the reference to Class 252 in (1) Note, Part B, for the coating and plastic compositions included in Class 252. Patent discloses species, all of which belong in Class 523, subclasses 1+ and claims broadly a composition which is not limited to the subject matter of said classes, the patent is placed in Class 520 in the subclasses first appearing therein provided for the disclosed species. Patents containing composition claims differing in scope only, some of which standing alone, belong in Class 106, and some in Class 520 are placed as originals and cross-referenced to Class 106 when desirable. (For coating or plastic compositions elsewhere classified.)

264,	Plastic and Nonmetallic Article Shaping or Treating: Processes,   appropriate subclassesfor processes of molding or shaping compositions of matter which include significant molding or shaping operation. The line between this class (106) and Class 264 is as follows: Class 106 takes processes of making compositions within the class definition even though including the step of molding, when such step is claimed broadly. Broad references to extruding, spinning into a setting medium (without naming the medium) or sheeting in a claim to the preparation of a composition of matter are considered broad molding steps. Also, the statement that heat and pressure are used during the molding, whether or not specific temperatures or specific pressures are recited, is not considered sufficient of itself to take a patent claiming a process of preparing a composition out of this class (106). For a more detailed discussion of the line between Class 264 and the composition classes, see the definition of Class 264. (Processes including preparation of coating or plastic compositions.)

For a definition of "significant" process, see the class definition of Class 427. (Processes including preparation of coating or plastic compositions.)
428,	Stock Material or Miscellaneous Articles,   except for subject matter classifiable in Class 428, subclasses 544+ , the line between this class (106) and Class 428 is as follows: A patent containing a claim to a product classifiable in Class 428, but with no significant structural limitation recited, and a claim to a coating material of the Class 106 type, which material is included as at least part of the claimed product, it is classified in Class 106 on the basis of the coating material.
