Classification: 424/520


(under the class definition) Compositions or products wherein the active ingredient is an animal tissue extract, animal body fluid, or animal material containing cellular structure of undetermined chemical constitution, i.e., the chemical structure of said animal derived material has not been sufficiently established to classify said material elsewhere.

(1) Note. Patents are classified in this and indented subclasses on the basis of the first active ingredient in the composition and on the basis of the immediate source of the animal material; e.g., certain constituents of urine may originate in the kidney, however the fact that urine is the immediate source of the constituent is deemed of sufficient significance to place a patent to a urine constituent in the urine subclass. "Active" denotes an ingredient having a physiological, pharmacological, or biological effect. In addition, since many active ingredients originate in various

tissue sources, a search to be complete, should include the appropriate subclasses providing for the source of the active ingredient.

(2) Note. The material derived from an animal may further be chemically modified or may be in a physical form different from that initially obtained; e.g., hydrogenated oil or butter derived from milk, etc. Classification is on the basis of the initial material derived from the animal.

(3) Note. Cellular material derived from animal is defined as a naturally occurring material which still retains a certain amount of the original tissue structure of the animal. Included within the term are materials which are chopped, cut, comminuted, pulverized, milled or sliced.

(4) Note. An extract is a material considered to be devoid of original cellular structure.

(5) Note. Specifically included in this subclass, with the exception of subject matter directed to arthropods, snakes, mollusks, fetuses and embryos, is subject matter directed to a whole animal or unspecified part thereof, i.e., a whole chopped up fish or a chopped up head of an animal. Though the whole body or general body part is known to contain multiple components such as muscle, bone, fat, blood, etc., the patents are not placed in subclasses directed to the individual components. They are considered to be general or unspecified cellular material derived from an animal.

(6) Note. Many of the patents previously classified in this and the indented subclasses have been transferred to the part of Class 514 or Class 530 providing for peptides and proteins. The patents remaining are patents which contain insufficient information to decide the chemical nature of the animal derived material. Before classifying a patent in this and the indented subclasses standard reference works such as biochemical dictionaries and physiology texts should be consulted to decide if a named extract is not really a peptide, protein or saccharide or other chemical compound of known chemical structure. (7) Note. Class 530, subclasses 820-859 provide a breakdown of organs and materials which are sources for proteins and peptides. No attempt has been made to cross-reference these patents here nor have the patents transferred to Class 530 been cross-referenced back to this and the indented subclasses.

(8) Note. Disposition of Other Extracts: (A) Class 512, Perfume Compositions, for plant or animal extracts or essential oils of unknown constitution which are disclosed as essences, aromatic oils, perfume essence, or odoriferous essential oils are considered to be compositions for perfumes even when they are from a single source. Processes for extracting these mixtures, such as processes of enfleurage, are also classified in Class 512, unless provided for

elsewhere; (B) Class 424, Plant extracts of unknown constitution which are disclosed as having a medicinal use, with or without other disclosed uses, are classified in Class 424, subclasses 195.1+; (C) Class 426, Extracts or essential oils of unknown constitution which have traditionally been employed as flavorings, flavor enhancers, seasoning agents, food acidulants or condiments are considered compositions and are classified in Class 426. A specific example is citrus oil which has been used for centuries as a flavoring agent. Processes for extracting such mixtures are classified in Class 426, unless provided for elsewhere, and are not provided for in the 532-570 Series of Classes; (D) Class 530, Animal or plant extracts derived from a single source so long as identified as a protein or peptide, are classified in Class 530 even if a Class 424 utility is disclosed or claimed. A plant or animal extract will be found in Class 424 if it is (a) a single source material and (b) is of undetermined chemical constitution, i.e., is claimed in terms of isolation technique or physical properties. A recitation as broad as "peptide" is enough to defeat placement in Class 424 on the basis of utility.
