CPC Definition - Subclass A01N

Last Updated Version: 2022.02
PRESERVATION OF BODIES OF HUMANS OR ANIMALS OR PLANTS OR PARTS THEREOF (preservation of food or foodstuff A23); BIOCIDES, e.g. AS DISINFECTANTS, AS PESTICIDES OR AS HERBICIDES (preparations for medical, dental or toilet purposes which kill or prevent the growth or proliferation of unwanted organisms A61K); PEST REPELLANTS OR ATTRACTANTS; PLANT GROWTH REGULATORS
Definition statement

This place covers:

Compositions, physical forms thereof, and the application or method of use of specific materials, compositions, or single compounds for the following purposes:

  • preserving or preventing the decay of dead human or animal bodies or parts thereof;
  • preserving living parts of human or animal bodies;
  • preserving or maintaining the freshness of plants or plant parts;
  • reducing the noxious effect of active ingredients on organisms other than unwanted organisms;
  • killing or preventing the growth or proliferation of unwanted organisms (e.g. insects, weeds, microorganisms);
  • repelling (i.e. resisting, warding off) or luring pests;
  • affecting plant growth through a chemical modification of the metabolism of plants using plant growth regulators, such as auxins.

Compositions used to protect the wound and scions of newly grafted plants or to cover the wounds on pruned plants (i.e. grafting wax).

Chemical agents used for the sexual sterilization of invertebrates (e.g. insects).

Relationships with other classification places

Subclass A01N may overlap with many other subclasses relating to the use of biocides. In general, classification in A01N is given to documents which are relevant for biocidal compositions or methods which are used on non-living subjects, plants, humans or animals when the desired effect is not mainly pharmaceutical or cosmetic. For example, compositions for protecting pets against insect pests are classified in A01N, whereas anthelmintic compositions are classified in A61K.

Insect repellant compositions or anti-lice shampoos are classified in A01N, whereas compositions where such an effect is only optional are classified in A61K.

Further, documents in which the disinfectant or biocidal effect depends on the application of a particular method or apparatus are classified in the relevant classes such as A61L (disinfectant methods) or B27K (wood impregnation). Only when a document relates to technical features that are essentially chemical (and biocidal) in nature should it be classified in A01N.

Documents disclosing chemical substances and/or the preparation thereof only are classified in A01N in cases where the biocidal or pesticidal effect is an essential part of the disclosure, for example when it is demonstrated in an example.

While substances that chemically modify a plant's metabolism are classified in A01N, compositions that affect the growth of a plant solely by supplying nutrients ordinarily required for growth, e.g. fertiliser, plant food, are classified in C05. Materials used to prevent or cure mineral deficiencies in plants, such as iron chelates used to cure iron chlorosis, are also classified in C05.

The activities (e.g. rodenticidal, herbicidal) of biocidal, pest repellant, pest attractant or plant growth regulatory preparations must also be classified in A01P when such activities are determined to be invention information.

When biocides, pest repellants, pest attractants or plant growth regulators are compounds or contain compounds which are determined to be invention information, the compounds must also be classified in C01C07C08 or C12N. When these compounds are considered to be of interest for search purposes, they may also be classified in C01C07C08 or C12N.

Special rules of classification

In A01N 27/00 - A01N 65/00, the last place priority rule is applied, i.e. at each hierarchical level, in the absence of an indication to the contrary, classification for an active ingredient is made in the last appropriate place.

Where a compound is described as existing in tautomeric forms, it is classified as if existing in the form that is classified last in the system.

Compounds covered by different main groups according to alternatively specified parts of their formulae are classified in all of the relevant main groups. (However, for practical reasons, for example to avoid too many classification symbols, only preferred or exemplified embodiments may be classified instead of every possible entity within the scope of a formula).

Generally, compounds are classified according to their chemical structure. However, in case the active ingredient is known to be a particular metabolite or derivative of the parent compound, the class for the actually active species should be given or at least also be given (see also the remarks under groups A01N 27/00, A01N 35/02 or A01N 59/00).

Salts formed between two or more organic compounds are classified as the compound providing the essential ion and it is also classified as the compound providing the other ion.

Salts or metal chelates of an organic compound are classified as that compound.

(However, in case the metal ion is the active species, this should be classified as well, for example as combination-sets (see below)).

In this subclass, a foodstuff is not considered as an active ingredient.

Different materials applied in sequence, at different times, are considered as a mixture of all materials employed. Synergistic or potentiated compositions are classified as if the synergist or potentiator is an active ingredient.

With respect to the classification of mixtures of active or formulation ingredients: see combination-sets below.

For this subclass the definitions of groups of chemical elements as given under the title of section C is used.

In groups A01N 25/00 - A01N 65/00 the symbol X means nitrogen, oxygen, sulfur or a halogen; Y means nitrogen, oxygen or sulfur. A dotted line between atoms by itself indicates an optional bond, an underscored dotted line

(

media0.png

) indicates a single or double bond.

Orthogonal indexing code A01N 2300/00 shall not be used as a single symbol, and is only used as a subsequent symbol in a C-Set. The information about how to use orthogonal indexing code A01N 2300/00 in a C-Set can be found in C-Sets classification in A01N 27/00.

Combination sets [C-Sets] classification:

In this subclass, C-Sets classification is applied to the following groups listed in the table below if the document discloses a pertinent combination of technical features that cannot be covered by the allocation of a single symbol. The fourth column of the table indicates the place where the detailed information about the C-Sets construction and the associated syntax rules can be found, in the definition section "Special rules of classification".

The specific C-Sets rule is located at only one place of the base symbol in the section "Special rules of classification" in the definition. If the C-Sets rule is applicable to all groups of a subclass, it is located at the subclass level only. If the same C-Sets rule is applicable to multiple groups or subgroups within the same subclass, the C-Sets rule is placed at the highest group or subgroup of the multiple groups.

Special rules of classification

Combination sets [C-Sets] classification:

C-Sets classifications [#A1Na1 and #A1Na2] are used in A01N 25/00.

If a document discloses a multitude of formulation-relevant ingredient, only the exemplified embodiments should be classified in C-Sets in order to avoid over-classification with C-Sets. However, if a document discloses a limited number of examples or no examples, but the document as a whole focuses on clearly specifically preferred embodiments, such clearly specifically preferred embodiments may be classified.

C-Sets statement: #A1Na1 and #A1Na2

  • In groups A01N 25/00-A01N 65/48, a mixture of an active ingredient with a formulation-relevant ingredient, or a composition that is characterized as a specific formulation, e.g., dispersion, emulsion, suspension, granule, particle, microcapsule, is classified in the form of C-Sets.
  • Both #A1Na1 and #A1Na2 are used for linking the information of active agent (with symbols A01N 27/00-A01N 65/48) with the formulation type or formulation auxiliaries (with symbols A01N 25/00-A01N 25/34), which appear relevant to the invention.
  • In #A1Na1, the base symbol, representing a formulation-relevant ingredient, is taken from the groups A01N 25/00-A01N 25/34, which is followed by a subsequent symbol selected from A01N 25/00-A01N 65/48. In #A1Na2, the base symbol is taken from groups A01N 27/00-A01N 65/48, which is followed by a subsequent symbol selected from A01N 25/00-A01N 25/34.

That said, it is important for a C-Set under #A1Na1 and #A1Na2 to represent the linked information by the base symbol and the subsequent symbol(s), while the choice of base symbol is discretionary; See discussion in C-Sets syntax rules below.

C-Sets syntax rules

  • Each C-Set shall contain at least two symbols.
  • Duplicate symbols are allowed in the C-Set.
  • The choice of base symbol is discretionary as long as the C-Set represents the relationship between the formulation-relevant ingredient and the composition ingredients. The choice of base symbol may be based on what is considered the most important aspect of the invention. In many situations, the practicality of classifying the invention with the fewest C-sets may determine the choice of the base symbol. See examples below.
  • The order of symbols in C-sets in #A1Na conveys the relationship between the base symbol and subsequent symbols. Only the base symbol has a relationship with the subsequent symbols and none of the subsequent symbols has a relationship with another subsequent symbol. Therefore, the order of subsequent symbols in a C-set in #A1Na is not critical as long as the information linking the base symbol and subsequent symbols is maintained.

C-Sets examples:

  • #A1Na: The use of a particular solvent in aqueous formulations. Examples disclose formulations with glyphosate or 2,4-D is classified as (A01N 25/02; A01N 39/04, A01N 57/20).

Should a specific surfactant in the formulation be considered to also contribute to the invention, then a further C-set is required to indicate this information, linking the surfactant with the exemplified active agents. The information is classified as (A01N 25/30, A01N 39/04, A01N 57/20).

C-Sets searches:

C-Sets search queries may be made according to C-Sets classification rules applicable to this group and its subgroups.

containing liquids as carriers, diluents or solvents
Definition statement

This place covers:

Compositions in which the solvent system is the distinguishing feature. Decisive is the actually disclosed form: solutions which are intended to be emulsified or dispersed such as emulsifiable or dispersible concentrates usually obtain the classification A01N 25/02 whereas the final diluted products obtain classification A01N 25/04.

Dispersions, {emulsions, suspoemulsions, suspension concentrates} or gels (foams A01N 25/16)
Definition statement

This place covers:

This group also covers nanoemulsions or nanodispersions.

In accordance with the Specification Guidelines for Liquid Formulated Pesticides of the FAO (cf. http://www.fao.org/docrep/007/y4353e/y4353e0b.htm), emulsifiable or dispersible concentrates are considered solutions whereas suspension concentrates, flowable concentrates, capsule suspensions and oil-based suspension concentrates are suspensions.

Powders or granules (A01N 25/26 takes precedence)
Definition statement

This place covers:

Also co-crystals or polymorphs.

wettable
Definition statement

This place covers:

Wettable powders, i.e. exclusively suspendable or dispersible powders or granulates. (Water) soluble powders: A01N 25/12.

Vapour or smoke emitting compositions with delayed or sustained release
Definition statement

This place covers:

Compositions/methods relating to sustained/delayed release of compounds in the vapor phase and not to a release in the liquid phase. In case of doubt this classification may be given.

Special rules of classification

Ethylene generators (e.g. ethephon) are also classified in this group.

Combination sets [C-Sets] classification:

In this group, C-Sets classifications [#A1Na1, #A1Na2, #A1Nb, and #A1Nb(2300)] are used.

The detailed information about the construction and associated syntax rules of C-Sets rules #A1Na1 and #A1Na2 can be found in the "Special rules of classification" in A01N 25/00.

C-Sets rules #A1Nb and #A1Nb (2300) are described below.

If a document discloses a multitude of mixtures of active ingredients or formulation-relevant ingredients, only the exemplified embodiments should be classified in C-Sets in order to avoid over-classification with C-Sets. However, if a document discloses a limited number of examples or no examples, but the document as a whole focuses on clearly specifically preferred embodiments, such clearly specifically preferred embodiments may be classified.

If a document discloses an invention including a mixture of two or more defined active ingredients as a specific formulation, C-Sets rules #A1Na1, #A1Na2 and #A1Nb are used to classify the invention.

C-Sets statement: #A1Nb and #A1Nb(2300)

  • In groups A01N 27/00-A01N 65/48, a mixture of active ingredients or combined application of multiple active ingredients is classified in the form of C-Sets.
  • #A1Nb vs. #A1Nb (2300): If a mixture of active ingredients or combined application of multiple active ingredients has defined active ingredients, C-Sets rule #A1Nb applies. If the mixture of active ingredients or combined application of multiple active ingredients has at least one defined active ingredient with an undefined active ingredient, C-Sets rule #A1Nb(2300) applies.
  • In #A1Nb, the base symbol is taken from the groups A01N 27/00-A01N 65/48, which is followed by subsequent symbol(s) that represent the rest of active ingredients, which is also taken from the groups A01N 27/00-A01N 65/48.
  • In #A1Nb (2300), the base symbol is taken from the groups A01N 27/00-A01N 65/48, which is followed by the subsequent symbol A01N 2300/00.

C-Sets syntax rules:

  • Each C-Set shall contain at least two symbols.
  • In #A1Nb, the choice of base symbol is up to the classifier as long as the relationship between the base symbol and symbols for the rest of the active ingredients and composition ingredients is maintained. The choice of base symbol may be based on what is considered the most important active ingredient, but in many situations, the practicality of classifying the invention with the fewest number of C-sets may determine the choice of the base symbol.

For example, a binary mixture of a biocide represented by symbol A01N 43/90 and a biocidal yeast is classified as either (A01N 43/90, A01N 63/32) or (A01N 63/32; A01N 43/90) with equal validity, but not both.

  • A special case occurs when a mixture of three or more defined active ingredients are disclosed. In this case, the C-set is given in a cascading way. For example, a mixture of biocidal Bacillus bacteria (A01N 63/22), biocidal yeast (A01N 63/32) and the chemical biocide represented by A01N 43/90 requires two combination sets: (A01N 63/22, A01N 63/32, A01N 43/90) and (A01N 63/32, A01N 43/90). The first C-set indicates the combination of bacteria with either yeast or chemical biocide, while the second indicates the combination of yeast with chemical biocide.
  • Duplicate symbols are allowed in a C-Set #A1Nb. When the base symbol and a subsequent symbol are identical, the required number of C-Sets may be reduced in certain special situations. For example, a ternary mixture of two triazole fungicides epoxiconazole (A01N 43/653), tebuconazole (A01N 43/653), and a Bacillus strain (A01N 63/22) is classified as (A01N 43/653, A01N 43/653, A01N 63/22). Typically, a ternary mixture requires at least one more C-Set in a cascading way, but a second C-Set is not needed in this example because the information linking either of the triazole fungicides to the Bacillus strain is already covered.
  • In #A1Nb, the order of symbols in C-sets in #A1Nb conveys the relationship between the base symbol and subsequent symbols. Only the base symbol has a relationship with the subsequent symbols and none of the subsequent symbols has a relationship with the other subsequent symbol(s). Therefore, the order of symbols in a C-set in #A1Nb is not critical when there are only two symbols in a C-set, but the order is critical when there are three or more symbols in a C-set.
  • In #A1Nb(2300), the order of symbols in a C-set is relevant in that A01N 2300/00 is always allocated as a subsequent symbol.
  • For an invention including a mixture of two or more defined active ingredients as a specific formulation, both C-Sets rules #A1Na and #A1Nb are used to classify the invention.

C-Sets examples:

  • #A1Nb: A mixture of glyphosate and dicamba is classified as (A01N 57/20, A01N 37/40).
  • #A1Nb: A mixture of glyphosate and 2,4-D is classified as (A01N 57/20, A01N 39/04).
  • #A1Nb: A mixture of glyphosate and a compound selected from dicamba and 2,4-D is classified as (A01N 57/20, A01N 37/40, A01N 39/04). Alternatively, it is also correct to classify the invention as two C-sets, (A01N 57/20, A01N 37/40) and (A01N 57/20, A01N 39/04). The first C-set (A01N 57/20, A01N 37/40, A01N 39/04) is preferable in this example because it results in fewer C-sets (one instead of two) while conveying the same information.

Special rules of classification

Combination sets [C-Sets] classification:

In this group, C-Sets classifications [#A1Na1, #A1Na2, #A1Nb, #A1Nb(2300) and #A1Nc] are used. The detailed information about the construction and associated syntax rules of C-Sets rules #A1Na1 and #A1Na2 can be found in the "Special rules of classification" in A01N 25/00.

C-Sets rules #A1Nb and #A1Nb(2300) are described in A01N 27/00.

C-Sets rule #A1Nc is described below.

If a document discloses a multitude of mixtures of active ingredients or formulation-relevant ingredient, only the exemplified embodiments should be classified in C-Sets in order to avoid over-classification with C-Sets. However, if a document discloses a limited number of examples or no examples, but the document as a whole focuses on clearly specifically preferred embodiments, such clearly specifically preferred embodiments may be classified.

C-Sets statement: #A1Nc:

In groups A01N 63/50 and A01N 63/60, a biocide, pest repellant or attractant, or plant growth regulator containing an isolated enzyme, isolated peptide, or isolated nucleic is classified in the form of C-Sets when the origin of the isolated enzyme, peptide, or nucleic acids is disclosed (e.g., bacteria, fungi, etc.).

  • In the C-Sets, the base symbol is either A01N 63/50 (in the case of isolated enzyme or isolated protein) or A01N 63/60 (in the case of isolated nucleic acids), which is followed by a subsequent symbol representing the origin of the isolated enzyme, protein or nucleic acids.
  • If a document discloses a multitude of active ingredients, only exemplified embodiments should be classified in C-Sets in order to avoid over-classification with C-Sets. However, if a document discloses a limited number of examples or no examples, but the document as a whole focuses on clearly specifically preferred embodiments, such clearly specifically preferred embodiments may be classified.

C-Sets syntax rules:

  • Each C-Set shall contain two symbols.
  • Duplicate symbols are not allowed in a C-Set.
  • The order of the symbols in the C-Sets is relevant, in which the isolated enzyme, isolated protein, or isolated nucleic acids is allocated as a base symbol and the origin of the isolated enzyme, isolated protein, or isolated nucleic acids (e.g. bacteria or fungi, etc.) is allocated as a subsequent symbol.
