Relationship between large subject matter areas

In class C07, the last place priority rule is used, i.e. in the absence of an indication to the contrary, a compound is classified in the last appropriate subclass. Hence, while individual heterocycle-containing amino acids are classified in C07D, peptides are generally classified in C07K. Similarly, compounds containing saccharide radicals, with the exception of polysaccharides, are classified in this subclass, and heterocyclic steroids are classified under C07J. Heterocycles incorporating elements other than C, H, halogen, N, O, S, Se, Te are classified in C07F.

This subclass is a function oriented entry for the compounds themselves and does not cover the application or use of the compounds under the subclass definition. For classifying such information other entries in IPC exist, for example:

  • Compounds or compositions for preservation of bodies of humans, animals, plants, or parts thereof, as biocides, e.g. disinfectants, pesticides, herbicides, as pest repellents or attractants, and as plant growth regulators are classified in A01N.
  • Preparations for medical, dental, or toilet purposes are classified in A61K.

Special rules of classification within this subclass/group

Only explicitly disclosed examples that are covered by the claims ("claimed examples") are classified.

The examiner first look at the claims and only classify the single examples of the description/claims falling within the scope of the claims.

Claimed embodiments are thus classified only if they represent an enabling disclosure, which could be used for a novelty/inventive step reasoning against another document.

Further compounds/processes of the description, which have not been claimed, are not classified.

Broad claims are hence disregarded for the purporse of classification as they would not be useful for novelty/inventive step.

If the patent (application) is of interest for other fields, further classification(s) must be given ("circulation of documents"), in order to ensure that the document can be found when searching in the relevant field.

Should the compound/process be classifed in C07H, the two following additional classifications are given only in the IPC (not in CPC).

Preparations for medical, dental, or toilet purposes
A61K (IPC)
Therapeutic activity of chemical compounds
A61P (IPC)

In this subclass, in the absence of an indication to the contrary, a compound is classified in the last appropriate place.

In general, and in the absence of any indication to the contrary, the terms "acyclic" and "aliphatic" are used to describe compounds in which there is no ring; and, if a ring were present, the compound would be taken by the "last place" rule to a later group for cycloaliphatic or aromatic compounds, if such a group exists.

Where a compound or an entire group of compounds exists in tautomeric forms, it is classified as though existing in the form which is classified last in the system, unless the other form is specifically mentioned earlier in the system.

Chemical compounds and their preparation are classified in the groups for the type of compound prepared. The processes of preparation are also classified in the groups for the types of reaction employed, if of interest.

General processes for the preparation of a class of compounds falling into more than one main group are classified in the groups for the processes employed, when such groups exist.

The compounds prepared are also always classified in the groups for the types of compound prepared.

That means that a process will be always be given at least a class for the products obtained by that process, regardless of whether the product is known or not.

For instance, a process for preparing glucose will always be assigned the classification for glucose (i.e. C07H 3/02) and additionally main group C07H 1/00 or one of its subgroups, if the process is of interest.

Salts of a compound, unless specifically provided for, are classified as that compound.

Metal chelates are classified in C07H 23/00.

Salts, adducts or complexes formed between two or more organic compounds are classified according to all compounds forming the salts, adducts or complexes.

In this subclass only compounds derived from acyclic polyhydroxy-aldehydes or acyclic polyhydroxy-ketones, or from their cyclic tautomers, by removing hydrogen atoms or by replacing hetero bonds to oxygen by the same number of hetero bonds to halogen, nitrogen, sulfur, selenium, or tellurium are classified.

The compounds of this subclass must have at least one of the following functional groups, wherein the two hetero bonds to oxygen can be replaced by the same number of hetero bonds to halogen, nitrogen, sulfur, selenium, or tellurium:

  • aldehyde
  • ketone
  • hemiacetal
  • hemiketal
  • acetal
  • ketal

Examples:

These compounds are not classified in C07H but in C07D, as no acetal group is present (the carbon atoms not forming a cyclic acetal are indicated by the arrows in the formulas below):

(classified only in C07D)

media0.png

According to definition (a)(iii) and (b) below for a saccharide radical, some compounds comprising hetero bonds to halogen, nitrogen, sulfur, selenium, or tellurium should be classified in C07H and not in C07D (following the last place rule). Nonetheless, both classifications C07H and C07D have sometimes been given, for example, the following compounds should be classified in C07H but might also have additional classification in C07D:

(should be classified in C07H but might have additional classification in C07D)

media3.png

The following compounds should only be classified in C07D (see definition (a)(iii) and (b) below for a saccharide radical), as they do not have at least three carbon atoms - at least two in the case of a skeleton having only four carbon atoms - having one single bond to oxygen (or to halogen, nitrogen, sulfur, selenium, or tellurium atom) as the only hetero bond:

media11.jpg
i) Contains within the carbon skeleton an unbranched sequence of at the most six carbon atoms in which at least three carbon atoms - at least two in the case of a skeleton having only four carbon atoms - have one single bond to an oxygen atom as the only hetero bond, and A) In a cyclic or acyclic sequence, at least one other carbon atom has two single bonds to oxygen atoms as the only hetero bonds, or B) In an acyclic sequence, at least one other arbon atom has one double bond to an oxygen atom as the only hetero bond, example: ii) The said sequence containing at the most one double bond, i.e. C=C or possibly ketalised C(=O), in addition to the hetero bonds mentioned above under (A) or (B), b) It is also a radical derived from a radical as defined in (a) above by replacing at the most four of the specified hetero bonds to oxygen by the same number of hetero bonds to halogen, nitrogen, sulfur, selenium, or tellurium; Note: "heterocyclic radical" or "hetero ring" is considered to exclude saccharide radicals as defined above. Example 1: neuraminic acid
media12.jpg
the saccharide radical of neuraminic acid consists of an uninterrupted carbon skeleton and oxygen atoms directly attached thereto, and is considered to be terminated by the bond of carbon number 1 to the carboxylic radical (the saccharide radical has 8 carbon atoms altogether). It contains: - (point i above) within the 8-carbon-atom skeleton an unbranched sequence of at the most six carbon atoms (see numbering below) in which at least three carbon atoms have one single bond to an oxygen atom as the only hetero bond (see carbon atoms numbered 3, 4, 5, 6), and - (point A above) in the cyclic sequence at least one other carbon atom (carbon 1) has two single bonds to oxygen atoms as the only hetero bonds, - (point ii above) the saccharide radical of neuraminic acid does not contain further double bonds, - it is derived by replacing one of the bond to oxygen by a bond to nitrogen (nitrogen connected to carbon 4) The first molecule (neuraminic acid) has one "non-saccharide" radical attached to carbon 1 and possible classification can only be C07H 7/027 (ketoaldonic acid at position 1, see also the WIPO definition at http://www.wipo.int/ipcpub/illustration/#symbol=C07H0007027000&count=1&version=20110101). The second molecule has one "non-saccharide" radical attached to carbon 1 ( C07H 7/027, ketoaldonic acid) another "non-saccharide" radical attached to carbon 1 ( C07H 15/02, methyl ether), the right classification is C07H 15/02 according to the last place priority rule, as the anomeric oxygen in methylated. Examples 2-3: in the following two examples the saccharide radical (for the purpose of this classification only) is the whole molecule, and the unbranched sequence of at the most six carbon atoms is indicated with a bracket within the saccharide radical:
media13.png
media14.png
Examples 4-5:
media75.png
The saccharide radical is the carbon skeleton of 7 carbon atoms, and the unbranched sequence of at the most six carbon atoms is numbered from 1 to 6 in the two molecules. The first molecule has two "non-saccharide" radicals attached to carbons 1 and 7, possible classifications could be C07H 7/04 ( phosphate radical at position 7 ) or C07H 15/02 (radical at oxygen at position 1). The correct classification is then C07H 15/02 according to the last place priority rule. The same applies to the second molecule, which has however only one possible classification, i.e. C07H 11/04. Examples 6-7:
media17.jpg
The saccharide radical is the carbon skeleton numbered from 1 to 6 in the two molecules . The saccharide radical starts at the anomeric carbon atom, having a bond to a carbon atom of a cyclic structure (phenyl), wich "terminates" the saccharide radical . The first molecule has one "non-saccharide" radical attached to carbon 1, the only possible classification is C07H 7/04 (phenyl group) . The second molecule has two "non-saccharide" radicals attached to carbon 1, possible classifications could be C07H 7/04 (phenyl group) or C07H 15/02 ( methyl at the oxygen connected to carbon 1). The correct classification of the second molecule is then C07H 15/02 according to the last place priority rule. Hemiacetal and hemiketal forms of saccharide radicals Saccharide radicals derived from cyclic tautomers of acyclic polyhydroxy-aldehydes or acyclic polyhydroxy-ketones are in cyclic hemiacetal and hemiketal forms. This is a type of stereoisomerism involving formation of an asymmetrical centre at the aldehyde carbon in aldoses and the keto carbon in ketoses. Examples are given for glucose and fructose below.
media18.png
Different projections exist for depicting those cyclic tautomers. The projections of α-D-glucopyranose are illustrated below:
media19.jpg
1 = fischer projection; 2 = haworth projection, 3 = chair/conformation projection, 4 = mills projection As illustrated for glucose and fructose, the cyclic structures are formed by the addition of the hydroxyl group (−OH) from either the fourth, fifth, or sixth carbon atom (in the diagram, the numbers 1 through 6 represent the positions of the carbon atoms) to the carbonyl group
media20.png
at position 1 in glucose or 2 in fructose. A five-membered ring is illustrated for the ketohexose, fructose; a six-membered ring is illustrated for the aldohexose, glucose. By definition, the carbon atom containing the aldehydo
media21.png
is termed the anomeric carbon atom; similarly, carbohydrate stereoisomers that differ in configuration only at this carbon atom are called anomers. When a cyclic hemiacetal or hemiketal structure forms, the structure with the new hydroxyl group projecting on the same side (in the fisher projection) as that of the oxygen involved in forming the ring is termed the alpha anomer that with the hydroxyl group projecting on the opposite side (in the fisher projection) from that of the oxygen ring is termed the beta anomer (see diagram).
media22.png
Note: Cyclic structure forms can be classified in C07H only if they have an anomeric carbon atom (i.e. a cyclic hemiacetal/acetal or hemiketal/ketal). Note: on the anomeric carbon the two hetero bonds to oxygen can be replaced by the same number of hetero bonds to halogen, nitrogen, sulfur, selenium, or tellurium (see point (b) above).
Salt
Compound consisting of at least one anionic part and at least one cationic part. Carboxylate salts – products where the hydrogen in a carboxyl group is replaced by an ion of metal or other cation.
Processes for the preparation of sugar derivatives
Special rules of classification within this group

Chemical compounds and their preparation are classified in the groups for the type of compound prepared. The processes of preparation are also classified in the groups for the types of reaction employed, if of interest.

General processes for the preparation of a class of compounds falling into more than one main group are classified in the groups for the processes employed, when such groups exist.

The compounds prepared are also always classified in the groups for the types of compound prepared.

That means that a process will be always be given at least a class for the products obtained by that process, regardless of whether the product is known or not.

For instance, a process for preparing glucose will always be assigned the classification for glucose (i.e. C07H 3/02) and additionally main group C07H 1/00 or one of its subgroups, if the process is of interest.
