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. DRUG AND BIO-AFFECTING COMPOSITIONS which are generally capable of:

1. Preventing, alleviating, treating, or curing abnormal and pathological conditions of the living body by such means as: (a) destroying a parasitic organism; (b) limiting the affect of the disease or abnormality by chemically altering the physiology of the host or parasite.

2. Maintaining, increasing, decreasing, limiting, or destroying a physiologic body function; e.g., vitamin compositions, sex sterilants, fertility inhibitors, growth promotors, etc.

3. Diagnosing a physiological condition or state by an in vivo test; e.g., X-ray contrast, etc.

4. Controlling or protecting an environment or living body by attracting, disabling, inhibiting, killing, modifying, repelling or retarding an animal or micro-organism. For example: (a) Nonfood baits, attractants, and lures; (b) Biocides including antibiotics of undetermined structure; (c) Warfare gases such as lachrymators, sternutators, etc.; (d) Chemical pest repellents and adhesive trapping agents.

B. BODY TREATING COMPOSITIONS generally intended for deodorizing, protecting, adorning, or grooming a body; e.g., cosmetics, dentifrices, embalming fluids, etc.

C. FERMENTATES (e.g., antibiotics, etc.), PLANT AND ANIMAL EXTRACTS, OR BODY FLUIDS OR MATERIAL CONTAINING PLANT OR ANIMAL CELLULAR STRUCTURE, PER SE, intended to be used for the purposes set forth in A and B above, and whose chemical structure is not sufficiently known to be classified elsewhere.

D. COMPOSITIONS OF THIS CLASS DEFINED IN TERMS OF SPECIFIC STRUCTURE; E.G., LAYERED TABLET, CAPSULE, ETC.

The lines generally prevailing between the composition classes and the article classes are applicable to Class 424, unless otherwise indicated, with the exception that Class 424 provides for a composition, per se, defined in terms of specific structure having a utility for Class 424 (see subclasses 400+).

E. PROCESSES OF USING the subject matter of the Class Definition, A through C above, and in Lines With Other Classes or Within This Class, Compositions Of This Class Defined In Terms Of Specific Structure; e.g., Layered Tablet, Capsule, Etc., A, above, or compounds, per se, for the purposes set forth in A and B of the Class Definition (See References to Other Classes, below, for those classes that that concern "processes." Note particularly the Search Notes for Use Processes involving Class 424 subject matter classified elsewhere.)

F. PROCESSES OF PREPARING subject matter of the Class Definition, A through C, and of Lines With Other Classes and Within This Class, Compositions Of This Class Defined In Terms Of Specific Structure; e.g., Layered Tablet, Capsule, Etc., part A.

G. ADJUVANT OR CARRIER COMPOSITIONS, PER SE, for perfecting compositions for this class.

(1) Note. This class is the generic home for compositions for treating a living body and for controlling a pest. (2) Note. The terms "mere use" or "mere application" as employed in the definitions of Class 424 and the search notes in other classes which refer to Class 424 are defined to encompass only a single step process and include expressions such as applying, contacting, dipping, spraying, injecting, combusting, administering orally, etc., recited either along or with recitations such as dosage amount or the treatment of a specific environment, organism, or body part. Examples of expressions considered mere use or mere application are "injecting 3 cc. of compound x into a vein" and "burning 20 grams of a sulfur fumigant in a room".

CLASSIFICATION GUIDELINES FOR THIS CLASS

A. In this class the chemical structure of the ingredient disclosed as having a utility set forth in the Class Definition above, is used as the primary basis of classification. Processes of using compositions or compounds, per se, and processes of making compositions, not provided for elsewhere, are classified in the first appearing subclass providing for the particular active ingredient being employed or prepared.

Compositions containing a biologically or pharmacologically active ingredient which generally, for example, control, cure, disable, inhibit, kill, modify, protect, repel, retard, sterilize or stimulate a living animal body; or inhibit or kill micro-organisms other than algae, etc., are provided for primarily in subclasses 85.1 and Class 514 appropriate subclasses. Compositions, intended for topical application, containing ingredients having other utilities under the class definition; e.g., grooming, enhancing, etc., which are not provided for in the Special subclasses 1.1-84, 125 and 126 have been classified in Class 514, appropriate subclasses.

B. The rule followed in classifying a patent having separate claims to several species of the active 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, except where there is a compulsory search note between the subclasses. 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; i.e., "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 specie claims, is followed.

C. A patent claiming a composition wherein the active compound or ingredient has not been specified, has been classified as original in the first appearing subclass providing for any one of the claimed ingredients and cross-referenced to appropriate lower subclasses providing for the remaining compounds or ingredients.

D. A patent claiming a composition resulting from a chemical reaction, wherein the chemical structure of the compounds or ingredients which make up the final composition are unknown or undetermined, is classified as original in the first appearing subclass providing for anyone of the reactants and cross-referenced to the lower subclasses providing for the other reactants.

E. Patents claiming synergistic or potentiated compositions have been classified as originals in the first appearing subclass providing for either the synergist, potentiator or active ingredient and cross-referenced to appropriate lower subclasses.

F. Patents claiming subject matter coming within the Special Subclasses 1.1-84, 125 and 126 have been classified on the basis of the disclosed or claimed function, or the particular subject matter provided for, in the first appearing subclass providing the same; e.g., Dentrifices, Embalming compositions, Solid synthetic organic polymer containing, etc., and no distinction has been made between the Class 424 active ingredients and nonactive ingredients with the one exception being applied to solid synthetic organic polymers, namely subclasses 78.01, 78.02+, and 78.08+. These subclasses consider only those polymers which are bioactive as defined therein.

G. Patents to adjuvant or carrier compositions, per se, which are claimed or solely disclosed for perfecting a composition for this class are classified as original in the first appearing appropriate subclass providing for any one of the ingredients in Class 514, appropriate subclasses, except where the claimed composition possesses a functional property or other feature which has been provided for in the Special subclasses 1.1-84, 125 and 126; e.g., Free carbon containing, Corrosion inhibitor containing, etc.

H. A patent claiming a Class 424 active ingredient broadly in terms of its function in combination with a specific adjuvant or carrier; e.g., "A tranquilizer and as a carrier therefore sugar and gelatin" has been classified as original in the first appearing subclass providing for any one of the disclosed specific active ingredients and cross-referenced to all other subclasses providing for the remaining disclosed active ingredients.

CLASSIFICATION LINES WITH OTHER CLASSES

A. General class lines

1.Compound Classes

a. Where a patent claims a composition in nominal terminology only; e.g., "A composition comprising a therapeutic amount of compound X", and there are no claims to a method of use, or true mixture, the original has been placed with the compound claimed. Some examples of nominal terminology are: "comprising as an active ingredient", "containing an effective amount of", "containing a lethal amount of, etc.

b. Where a patent claims dosage units (in the absence of more comprehensive or controlling claims as indicated below); e.g., "a tablet comprising (or containing) 15 grains of compound X" and in the absence of any structural limitations, definite shape, surface deformation, etc., the original has been placed with the compound.

c. Where a patent claims a composition wherein (1) another ingredient is recited, however broadly, or (2) proportions are recited, the original has been placed in Class 424. Some examples of claims reciting the following types of terminology are included herewith: "with a carrier", "with a solvent", "with an adjuvant", "with an emulsifier", "wetting agent", "solubilizer", "surface active agent", "extending agent", "buffering agent", "from 5% to 90%", "at least .05%", "minor proportion of compound X and major portions of carrier", etc.

d. Where a patent contains at least one claim to a method of use, even if only nominally recited; e.g., "a method of killing insects by applying compound X", the original has been placed in Class 424 (except when another use is also claimed which is superior to Class 424).

e. Where the patent claims an animal or plant extract of undetermined constitution, which is solely disclosed as being suitable for a Class 424 utility, the original will go to Class 424. Processes for obtaining such extracts will also be classified in Class 424 unless specifically provided for elsewhere.

1a. Cross References From Compound Classes

In most instances, cross-referencing from the compound classes into Class 424 has been limited to those disclosures which provide (1) a specific composition; e.g., numerical values setting forth definite amounts for all ingredients of the composition having Class 424 properties, and (2) processes of using a compound for a Class 424 purpose wherein the process is significant in that it sets forth the administration of the active ingredient in more than just nominal terminology, i.e., it recites administering a specific amount of a compound to treat a specific condition in a specified host. Patents containing a mere recitation that a compound may be administered; e.g., orally, in association with an unspecified pharmaceutical carrier will be excluded as cross-references.

2. Composition Classes

The following general lines exist between Class 424 and the other composition classes or with classes containing patents wherein the claims recite a composition limited to an art use provided for in that class.

a. 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.

b. A list of superiority of composition classes appears in the main class definition of Class 252 Compositions (5) Note. This note in Class 252 explains classification of a generic composition with several disclosed uses.

424, Drug, Bio-Affecting and Body Treating Compositions

71, Chemistry: Fertilizers,

149, Explosive and Thermic Compositions or Charges

148, Metal Treatment

252, Compositions, (special uses and functions) through subclass 88.2.

510, Cleaning Compositions for Solid Surfaces, Auxiliary Compositions Therefor, or Processes of Preparing the Compositions.

252, Compositions, (special uses and functions) through subclass 194.

106, Compositions: Coating or Plastic

520, Synthetic Resins or Natural Rubbers, subclasses 1+

260, Chemistry of Carbon Compounds

585, Chemistry of Hydrocarbon Compounds

252, Compositions, (nonspecial uses or functions).

426, Food or Edible Material: Processes, Compositions, and Products.

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 and the above listed classes are determined.

B. Lines With Related Composition Classes

CLASS 504

1. Class 504 PLANT PROTECTING AND REGULATING COMPOSITIONS, provides for compositions having a stimulating, inhibiting (herbicides), or regulating action on plant growth and methods of using such compositions. Class 504 specifically provides for algicidal compositions and fertilizer compositions which contain an insecticide, fungicide, or deodorant. Class 504 is superior to Class 424. (See above for a list of superiority of composition classes).

2. If claims are drawn to a "pesticide" composition or method without specifically reciting the nature of the "pest" to be controlled or eradicated, the patent is placed as original in Class 424 when only a Class 424 type of "pest" (e.g., fungi, insect, rodent, etc.) is revealed in the patent disclosure. However, if both Class 504 and Class 424 types of "pest" are specifically disclosed or if no disclosure is made as to the specific type of pest, the patent is placed in Class 504 as original and cross-referenced to Class 424.

CLASS 8

1. Class 8, BLEACHING AND DYEING; FLUID TREATMENT AND CHEMICAL MODIFICATION OF TEXTILES AND FIBERS, provides for processes of dyeing hair on a living animal, not provided for elsewhere, processes of depilating (i.e., removing hair, fur, or feathers) a living animal and for processes of chemical modification of hair not on a living body. Class 8 also provides for compositions used in these processes.

2. Class 424 provides for a composition for treating hair (e.g., waving etc.) on a living body, and methods of use which are no more than the mere application of the composition. To be placed in Class 424, a patent must either specifically disclose or claim that the hair is on a living body; e.g., living hair, etc., or contain other disclosure which definitely indicates an intent to use the composition or process on a living body; e.g., not injurious to the person, etc. Recitation that the hair is on the body; e.g., scalp, etc., will be presumed to indicate that the body is living in the absence of disclosure to the contrary. The mere recitation "human hair" by itself is not enough to indicate that the hair is on a living body.

CLASS 71

1. Class 71, CHEMISTRY: FERTILIZERS, provides for compositions having a nutrient action on plant growth and methods of using such compositions.

3. Class 424 provides for compositions containing a food or beverage when said compositions are claimed or solely disclosed as having a utility set forth in I above. However, a food or beverage containing a biocide as a preservative therefore will be classified as original in Class 426. Class 424 also provides for methods of preserving Class 426 products when said methods are no more than the mere use of biocides.

4. Class 424 further provides for food or beverage compositions containing an animal growth regulator or other anabolic agents. For purposes of classification, an animal growth regulator or anabolic agent is defined to include the following illustrative causative effects:

a. increase feed efficiency or weight gain

b. enhance color of egg yolks, combs, skin, or legs of chickens

c. enhance the hatchability of eggs

d. vary the fat-protein ratio or texture of flesh

e. chemically caponize an animal, etc.

5. Compositions wherein the nutritional ingredients fat, carbohydrate, or protein are varied to achieve a varied fat-flesh ratio in an animal or varied to meet the special nutritional needs of an abnormal metabolic condition; e.g., diabetes, etc., will not be considered as subject matter for Class 424.

CLASS 106

1. Class 106, COMPOSITIONS: COATING OR PLASTIC, provides for coating compositions which protect a base by forming a tough adherent film even though the composition also contains a biocide to protect the base against biological attack; e.g., marine antifouling paints, etc.

2. Materials or ingredients for coating and molding compositions (Class 106 appropriate subclasses) which are also useful as diluents or inert ingredients in pharmaceutical compositions are placed in Class 106 unless a therapeutic or biocidal property is claimed. Surgical sponges claimed only as being made from Class 106 compositions are placed in Class 106 if the sponge contains no active ingredient with a utility for Class 424. Patents claiming an ink suitable for coating or printing on pharmaceutical dosage units; e.g., tablets, etc., are placed in Class 106 unless the coated or printed article is also claimed.

3. Class 424 provides for the following coating compositions: compositions intended to decorate or beautify the body; e.g., hair lacquer, fingernail polish, lipstick, etc.; coating compositions which do not protect the base by forming a tough, adherent film and whose sole function is as a carrier for a composition of Class 424 utility; e.g., "stickers" which adhere insecticides to plants etc., whether or not claimed in combination with an active ingredient; coating compositions applied to the body for therapeutic purposes even though a tough, adherent film is formed; and coating compositions which do not form tough, adherent films and which have a utility provided for in Class 424; e.g., salve, skin cream, or a solution of a material, for example, a mixture of phenols to protect wood against insect, etc.

CLASS 119

1. Class 119, ANIMAL HUSBANDRY, provides for an animal litter composition, per se.

2. Class 424 takes litter compositions combined with a compound or composition having a Class 424 utility; e.g., a biocide, etc.

CLASS 127

1. Class 127, SUGAR, STARCH, AND CARBOHYDRATES, provides for sugar, starch, and carbohydrates, per se, and their hydrolysis products, even if these materials have utility provided for in Class 424.

2. Class 424 provides for compositions containing sugar, starch, or carbohydrates; e.g., a blend of two carbohydrates, etc., having a claimed or solely disclosed utility provided for in Class 424.

CLASS 131

1. Class 131, TOBACCO, provides for tobacco compositions to be employed to enhance the users" well-being or enjoyment when smoked, chewed, or inhaled including snuff, and takes these compositions even when they have a Class 424 utility; e.g., medicated smoking tobacco, etc. Class 131 also provides for tobacco substitutes or compositions intended to decrease the individual"s need for tobacco and which are to be used in the same manner as tobacco; e.g., smoking, etc.

2. Class 424 takes a tobacco containing composition which is not intended to be smoked, chewed, etc. for the users" enjoyment; e.g., tobacco used as an insecticide, tobacco burned as a fumigant, etc., when said composition is claimed or solely disclosed for a Class 424 purpose. If the tobacco containing composition has plural functions with some functions provided for in Class 131 and some in Class 424, the patent will be placed in Class 131 as an original and crossed to Class 424. Class 424 also provides for compositions intended to decrease a person"s use of tobacco, but which are not intended to be smoked, chewed, etc., as tobacco; e.g., ingested or injected, etc.

CLASS 435

1. Class 435, CHEMISTRY: MOLECULAR BIOLOGY AND MICROBIOLOGY, provides for enzymes, per se, which are not more specifically provided for elsewhere, and enzyme compositions containing a preservative unless a Class 424 utility is recited in the claim or is the sole utility disclosed. Class 435 also takes a composition or method employing a line micro-organism for an in vitro test.

2. Class 424 provides for fermentates; e.g., antibiotics, etc., of unknown chemical structure wherein the fermentate is claimed or disclosed to have a utility specified in Class 424.

4. Class 424 provides for compositions for in vivo measuring, testing, or diagnosis and methods of using said compositions or a compound for in vivo measuring, testing or diagnosis. This includes in vivo testing compositions containing an enzyme.

CLASS 252

1. Class 510, CLEANING COMPOSITIONS FOR SOLID SURFACES, AUXILIARY COMPOSITIONS THEREFOR, OR PROCESSES OF PREPARING THE COMPOSITIONS, provides for biocide containing cleaning and detergent compositions having a mere cleaning function.

2. Class 252 provides for compositions specifically classified therein protected against biological attack by a composition otherwise classifiable in Class 424. Class 252, provides for stabilized compositions where the ingredients other than the stabilizers are claimed so broadly as not to furnish a basis of classification (e.g., a carbon compound, etc.).

3. See Class 512 for perfume compositions, per se.

4. Class 424 takes all other detergent or emulsifier containing compositions which are claimed or solely disclosed for a Class 424 purpose.
