SECTION I - CLASS DEFINITION

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".

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

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.

504, Plant Protecting and Regulating Compositions

424, Drug, Bio-Affecting and Body Treating Compositions

71, Chemistry: Fertilizers,

149, Explosive and Thermic Compositions or Charges

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.

CLASS 426

1. Class 426, FOOD OR EDIBLE MATERIAL: PROCESSES, COMPOSITIONS, AND PRODUCTS, provides for compositions intended to nourish an animal by natural oral ingestion, which may contain an additive necessary to maintain the normal metabolism of the animal; e.g., vitamins, minerals, amino acids, etc.

2. Class 424 provides for compositions intended to nourish an animal when such compositions are designed to be administered to the animal by routes other than the oral cavity; e.g., by rectal or parenteral injection, or via a tube through the alimentary tract or stomach wall.

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.

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.

SUBCLASSES

[List of Patents for class 424 subclass 1.11]    1.11RADIONUCLIDE OR INTENDED RADIONUCLIDE CONTAINING; ADJUVANT OR CARRIER COMPOSITIONS; INTERMEDIATE OR PREPARATORY COMPOSITIONS:
 This subclass is indented under the class definition.  Compositions containing a radionuclide or an element intended to be converted to a radionuclide (such as Boron-10 which may be neutron-activated for radio-therapy); methods of making such compositions; class defined methods of using such compositions; class defined methods of using compounds, per se, containing a radionuclide or an element intended to be converted to a radionuclide; adjuvant or carrier compositions for perfecting compositions of this class; and intermediate or preparatory compositions for compounds or compositions proper for Class 424.
(1) Note. Radionuclide is an unstable isotope, capable of emitting radiant energy through a process termed decay. Commonly used terms which are substantially synonymous include: radiolabeled, radioactive, and radioisotope.
(2) Note. An intended radionuclide is an element which is by disclosure or common knowledge intended to be converted to a radionuclide to take advantage of the property or properties exhibited by a radionuclide. This subclass and indented subclasses should be read as incorporating the intended radionuclide embodiment in every instance.
(3) Note. All elements have multiple isotopes; some radioactive, some not; some naturally occurring; and some man-made. The recitation of a radionuclide will inherently encompass a mixture of isotopes; however, this is not sufficient for placement in Class 424. For placement in Class 424, an intentional mixture of different compounds or different elements or one (or more) of each is required.
(4) Note. Class 424 takes compounds mixed with a preserving agent when disclosed or claimed for a Class 424 function or utility. Further, Class 424 provides for a solution of a compound when disclosed or claimed for a Class 424 function or utility.
(5) Note. The intermediate and preparatory compositions are provided for in this subclass and indented subclasses, even though the radionuclide or intended radionuclide may not be present in the claim. The adjuvant and carrier compositions are provided for in this and indented subclasses, even though the radionuclide or intended radionuclide may not be present in the claim. When there are also disclosed or claimed non-radionuclide uses of the intermediate, preparatory, adjuvant, or carrier composition, appropriate cross-references are necessary elsewhere in Classes 424 and 514.
(6) Note. Subclass 1.11 is the appropriate residual location for those compositions, and the appropriate class defined uses, containing a per se radionuclide element or a per se intended radionuclide element (i.e., the elemental material). For example, compositions and methods comprising radioactive Radon baths are found here. Any indication of a compound; i.e., attachment (e.g., recitation of an ion), dictates that proper placement is in an indented subclass, even in the absence of a specifically disclosed compound. In the case of an indicated, but not specifically disclosed compound, the original would be placed in subclass 1.61 and a cross placed in: subclass 1.65 for metal radionuclide or intended metal radionuclide; subclasses 1.81+ for nonmetal radionuclide or intended nonmetal radionuclide; or both.
(7) Note. The following rule adheres to the rule set forth in Class 514, which statement in Class 514: (A) this and indented subclasses do not provide for cross-reference patents which are originally classified in Class 260, compound areas, or in the Class 530-570 series or in Class 585. Cross-reference patents that are originally classified in the Class 520 series are permitted; (B) the cross-reference rule elaborated above means that a specific compound having a disclosed or even specifically claimed utility (i.e., compound X having an attached radionuclide useful as an anti-cancer diagnostic or treatment agent) will be classifiable only in Class 260 or the Class 530-570 series or Class 585.
(8) Note. The terminology "derivative thereof" means that the compound retains the biological activity of the compound from which the subclass provides and from which it is derived, or that the compound retains the structural characteristic that places it in the subclass.
(9) Note. Kits. Claims and disclosures to in vivo kits are classified according to the following guidelines. The use of nominal terms to identify the kit such as "kit," "vial," "container," etc., are disregarded and placement is premised on the radiolabeled product intended for placement in the body even if the ingredients actually recited do not include all the necessary components to form the radiolabeled product (e.g., intermediate). The presence of an accessory such as "instructions", "syringe", "filter", etc., have no effect on this aspect of placement. Claiming of significant packaging or container structure will result in placement in Class 206 when the packaging requirements of that class definition is satisfied.

[List of Patents for class 424 subclass 78.01]    78.01DIGESTIVE SYSTEM REGULATOR CONTAINING SOLID SYNTHETIC ORGANIC POLYMER AS DESIGNATED ORGANIC ACTIVE INGREDIENT (DOAI) (E.G., ANTI-DIARRHETIC, ANTICONSTIPATION, APPETITE SUPPRESSANT, LAXATIVE, ETC.):
 This subclass is indented under the class definition.  Subject matter wherein the active ingredient is a solid synthetic organic polymer used to treat or regulate the digestive system; e.g., diarrhea, constipation, etc.
(1) Note. The term designated organic active ingredient (DOAI) denotes one which imparts a physiological, pharmacological, or biological effect. Please refer to Class 514, Main Class Definition, (3) Note, for further elaboration on this.
(2) Note. This subclass provides for compositions containing a solid synthetic polymer as a DOAI, methods of making such compositions, and mere methods of using such compositions. A composition, for example, containing a laxative (DOAI) and a solid synthetic polymer used merely as a binder or as a slow release agent is not classified here, but is classified in subclasses 400+ when there is special structure or in Class 514, based on the laxative.
(3) Note. See Class 520, subclass 1, (9) Note, for a more complete discussion of what is a solid synthetic polymer. No weight is given to expressions designating molecular weight; e.g., 1,000, 40,000, etc., since these numbers can reflect solid, waxy, or liquid polymers alike.

[List of Patents for class 424 subclass 78.02]    78.02TOPICAL BODY PREPARATION CONTAINING SOLID SYNTHETIC ORGANIC POLYMER AS DESIGNATED ORGANIC ACTIVE INGREDIENT (DOAI):
 This subclass is indented under the class definition.  Subject matter wherein the designated organic active ingredient (DOAI) is a solid synthetic polymer used topically to treat a living animal.
(1) Note. The term designated organic active ingredient (DOAI) denotes a polymer which exhibits a physiological, pharmacological, or biological effect. Also, a solid synthetic polymer will be classified here if it behaves as a synergist or potentiator, i.e., one which will cooperatively act with an active ingredient to the extent that the total effect will be greater than the sum of the two individual effects. See (2) and (4) Notes below for further details on topical coatings.
(2) Note. Topical preparations are those medications whose properties are designed either to treat superficial areas; e.g., mucosa of the eyes, nose, mouth (not throat), etc., or epidermis; e.g., skin rashes, burns, lesions, rectum, and other external body parts. There are also medications, though applied topically, which are designed to be absorbed transdermally with the intention of being absorbed into the blood stream. For example, a scopolamine patch (a patch, per se, implies no structure) is used to treat motion sickness, a nitroglycerine patch is used to treat angina pectoris, and finally a clonidine patch is used to treat hypertension; likewise, nasal sprays to relieve sinus congestion or pain as well as rectal suppositories are all excluded from this subclass. A drug parenterally administered; i.e., intramuscularly, subcutaneously, or intravenously injected, is also excluded from this subclass. Patents placed here typically treat skin lesions, inflammations; e.g., iliac stoma, etc.
(3) Note. See Class 520, subclass 1, (9) Note, for a more complete discussion on what is a solid synthetic resin. No consideration is given to numerical expressions of molecular weight since these numbers can reflect solid, waxy, or liquid polymers.
(4) Note. This note serves to distinguish this class (424), subclasses 78.02 - 78.07 with Class 514, appropriate subclasses, and Class 523, subclasses 105+. A pharmaceutical or cosmetic composition is always sufficient for placement in Class 424. A composition containing a solid synthetic polymer, with or without a DOAI, used to form a barrier layer or film on living animals to ward off harmful or disturbing agents; e.g., radiation, animals, insects, chemicals, allergens, etc., to promote healing; e.g., burns, etc., or to reduce inflammation or irritation, etc., is proper herein. A surgical adhesive composition to be coated on a fabric, gauze, tape, etc., is classified in Class 523, subclass 111. A surgical adhesive composition; e.g., alphacyanoacrylate, when applied directly to living animal tissues is classified herein.
(5) Note. A topical body preparation appropriate for this class, whose composition contains a monomer, prepolymer, or other chemical intermediates which forms a solid synthetic polymer after being applied and without the aid of catalysis, other than heat or water, is properly classified herein. Otherwise, classification is in Class 514, subclasses 772+. See this class, subclass 78.06 for examples to compositions containing moisture polymerizable alpha-cyano-acrylate to seal wounds and incisions.
(6) Note. A composition containing a solid synthetic polymer as DOAI broadly disclosed or claimed as a germicide will be classified here since many of them are used topically.
