401	.. Composition contains identified material other than water:

This subclass is indented under subclass 400. Subject matter wherein the composition contains material, other than water, which meets the definition of identified material for these subclasses.

(1) Note. For the purposes of subclasses 401-506 of this class "identified material" is defined to mean material wherein at least one chemical atom is identified, e.g., amine, hydrocarbon, alcohol, ether, etc. Identified material is material wherein at least one of the chemical atoms can be deduced with certainty. For purposes of these subclasses, organic material although inherently reciting the presence of a carbon atom is considered to be too broad. An exemplary list of materials to be regarded as identified material is as follows: metal hydrate, chalcogen, carboxylic acid, peroxy, peroxide, alkali or alkaline earth metal, halogen, sulfide, oil, fat, fatty acid or ester, etc. Identified material is by no means limited to the above noted examples. The list below is not exhaustive and merely enumerates certain materials that will not be considered as identified material, e.g., organic compound, metal containing, inorganic compound, organometallic, solvent, pigment, aggregate, filler, hydrophobic, hydrophillic, plasticizer, preservative, antioxidant, stabilizer, lubricant, fibrous, particulate, liquid, solid gas, dispersant, emulsifier, surfactant, surface active agent, crystalline, plastic, fluorescent, phosphorescent, luminescent, deliquescent, drier, humectant, blue color, numerically described without providing a chemical atom, Lewis acid or base, mineral, organic solvent, co-solvent, free radical, amphoteric, anionic, cationic, ionic, dielectric, conductor, insulator, etc.

(2) Note. While water fits the intent of what one would consider an identified material under this definition, water is positively excluded from subclasses 401+ as not sufficient by itself to place a composition in these subclasses.

(3) Note. For subclass indents, the same requirement for identified material obtains, for example, a composition containing organic solvent and a phthalocyanine would not be sufficient to bring a composition into subclass 413, etc.

(4) Note. Special terms used in the subclass titles, whether meeting the definition of identified material or not, are considered sufficient to bring a composition into the subclass, e.g., cork, fly ash, organic refuse, mica, etc.

Carbon coloring compounds which are produced in the presence of a preformed substratum, wherein novelty is alleged to reside in the combination or in the amount, form, or nature of the substratum, are in this class (106); however, where the substratum is synthesized simultaneously with the carbon compound, the product belongs in Class 260.
