CHEMISTRY; METALLURGY
Note(s) [2009.01]
- In section C, the definitions of groups of chemical elements are as follows:
- Alkali metals: Li, Na, K, Rb, Cs, Fr
- Alkaline earth metals: Ca, Sr, Ba, Ra
- Lanthanides: elements with atomic numbers 57 to 71 inclusive
- Rare earths: Sc, Y, Lanthanides
- Actinides: elements with atomic numbers 89 to 103 inclusive
- Refractory metals: Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, W
- Halogens: F, Cl, Br, I, At
- Noble gases: He, Ne, Ar, Kr, Xe, Rn
- Platinum group: Os, Ir, Pt, Ru, Rh, Pd
- Noble metals: Ag, Au, Platinum group
- Light metals: alkali metals, alkaline earth metals, Be, Al, Mg
- Heavy metals: metals other than light metals
- Iron group: Fe, Co, Ni
- Non-metals: H, B, C, Si, N, P, O, S, Se, Te, noble gases, halogens
- Metals: elements other than non-metals
- Transition elements: elements with atomic numbers 21 to 30 inclusive, 39 to 48 inclusive, 57 to 80 inclusive, 89 upwards
- Section C covers :
- pure chemistry, which covers inorganic compounds, organic compounds, macromolecular compounds, and their methods of preparation;
- applied chemistry, which covers compositions containing the above compounds, such as: glass, ceramics, fertilisers, plastics compositions, paints, products of the petroleum industry. It also covers certain compositions on account of their having particular properties rendering them suitable for certain purposes, as in the case of explosives, dyestuffs, adhesives, lubricants, and detergents;
- certain marginal industries, such as the manufacture of coke and of solid or gaseous fuels, the production and refining of oils, fats and waxes, the fermentation industry (e.g., brewing and wine-making), the sugar industry;
- certain operations or treatments, which are either purely mechanical, e.g., the mechanical treatment of leather and skins, or partly mechanical, e.g., the treatment of water or the prevention of corrosion in general;
- metallurgy, ferrous or non-ferrous alloys.
- In all sections of the IPC, in the absence of an indication to the contrary, the Periodic System of chemical elements referred to is the one with 18 groups as represented in the table below.
- In the case of operations, treatments, products or articles having both a chemical and a non-chemical part or aspect, the general rule is that the chemical part or aspect is covered by section C.
- In some of these cases, the chemical part or aspect brings with it a non-chemical one, even though purely mechanical, because this latter aspect either is essential to the operation or treatment or constitutes an important element thereof. It has seemed, in fact, more logical not to dissociate the different parts or aspects of a coherent whole. This is the case for applied chemistry and for the industries, operations and treatments mentioned in Notes (1)(c), (d) and (e). For example, furnaces peculiar to the manufacture of glass are covered by class C03 and not by class F27.
- There are, however, some exceptions in which the mechanical (or non-chemical) aspect carries with it the chemical aspect, for example:
- Certain extractive processes, in subclass A61K;
- The chemical purification of air, in subclass A61L;
- Chemical methods of fire-fighting, in subclass A62D;
- Chemical processes and apparatus, in class B01;
- Impregnation of wood, in subclass B27K;
- Chemical methods of analysis or testing, in subclass G01N;
- Photographic materials and processes, in class G03, and, generally, the chemical treatment of textiles and the production of cellulose or paper, in section D.
- In still other cases, the pure chemical aspect is covered by section C and the applied chemical aspect by another section, such as A, B or F, e.g., the use of a substance or composition for:
- When the chemical and mechanical aspects are so closely interlocked that a neat and simple division is not possible, or when certain mechanical processes follow as a natural or logical continuation of a chemical treatment, section C may cover, in addition to the chemical aspect, a part only of the mechanical aspect, e.g., after-treatment of artificial stone, covered by class C04. In this latter case, a note or a reference is usually given to make the position clear, even if sometimes the division is rather arbitrary.
CHEMISTRY
ORGANIC MACROMOLECULAR COMPOUNDS; THEIR PREPARATION OR CHEMICAL WORKING-UP; COMPOSITIONS BASED THEREON
Note(s) [2012.01]
- This class does not cover the following macromolecular compounds per se:
- peptides, e.g. proteins, which are covered by subclass C07K;
- compounds containing two or more mononucleotide units having separate phosphate or polyphosphate groups linked by saccharide radicals of nucleoside groups, e.g. nucleic acids, which are covered by group C07H 21/00;
- DNA or RNA concerning genetic engineering, vectors, e.g. plasmids, or their isolation, preparation or purification, which are covered by group C12N 15/00.
- Biocidal, pest repellant, pest attractant or plant growth regulatory activity of compounds or preparations is further classified in subclass A01P.
Note(s) [2006.01]
- In this subclass, the following term is used with the meaning indicated:
- In this subclass:
- compositions are classified according to the mutual proportions by weight of only the macromolecular constituents;
- compositions are classified according to the macromolecular constituent or constituents present in the highest proportion; if all these constituents are present in equal proportions the composition is classified according to each of these constituents.
- Any macromolecular constituent of a composition which is not identified by the classification according to Note (2) above, and the use of which is determined to be novel and non-obvious, must also be classified in this subclass. For example, a composition containing 80 parts polyethene and 20 parts polyvinyl chloride is classified in both groups C08L 23/06 and C08L 27/06, if the use of polyvinyl chloride is determined to be novel and non-obvious.
- Any macromolecular constituent of a composition which is not identified by the classification according to Notes (2) or (3) above, and which is considered to represent information of interest for search, may also be classified in this subclass. This can, for example, be the case when it is considered of interest to enable searching of compositions using a combination of classification symbols. Such non-obligatory classification should be given as "additional information".
