Definition statement
This subclass/group 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, micro-organisms);
  • 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).

Relationship between large subject matter areas

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 or on plants or on 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 repellent 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 it should 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.

When biocides, pest repellents, 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 C01, C07, C08 or C12N. When these compounds are considered to be of interest for search purposes, they may also be classified in C01, C07, C08 or C12N.

Special rules of classification within this subclass

In groups A01N 27/00 to A01N 65/00 classification is made in the last appropriate place for an active ingredient, unless otherwise indicated ('Last place rule').

Where a compound is described as existing in tautomeric forms, it is classified as if existing in the form which 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 to A01N 65/00 the symbol X means nitrogen, oxygen, sulfur or a halogen; Y means nitrogen, oxygen or sulfur. A dotted line between atoms indicates an optional bond, e.g.

indicates a single or double bond.

Classification of complementary information:

For compositions containing one or more active ingredients in combination or with formulation relevant ingredients (such as surfactants), for example particular formulations such as emulsions or mixtures of active ingredients, the symbol A01N 2300/00 is added to the classification symbol (e.g. A01N 57/20, A01N 2300/00 for compositions comprising glyphosate as main ingredient and a second active or a particular surfactant as second or further ingredient. The second ingredient is then added to the combination-set, in this case A01N 25/30 (in case the surfactant is essential) or the particular group of the second active ingredient).

Combination-sets

In groups A01N 25/00 to A01N 65/00, it is required to use combination-sets for classifying mixtures of (active or formulation-relevant) ingredients.

In this system classes of additional ingredients of mixtures or specific formulation types are added to the combination-set of the main ingredient. The additional ingredient may be a further active ingredient (for example in case of synergistic mixtures) or may relate to a particular special formulation-ingredient (such as a surfactant or safener (which in this case also considered a formulation-ingredient: see also the remarks under class A01N 25/32) or to a special formulation embodiment (like a wettable powder or microcapsule).

For example: a document disclosing a mixture of active ingredient A with further active ingredients B, C or D obtains as main classification for active ingredient A with the additional classifications for B, C and D in the combination-set. In case a document discloses as essential feature a particular formulation of compound A, a A01N25/xx classification is added to the combination-set (in these cases the main classification for A receives the additional symbol A01N 2300/00).

NB: Groups A01N 25/00 to A01N 25/34 do not obtain a A01N 2300/00-class, but these groups may be added to the combination-set of active ingredients.

Alternatively, in case a document discloses a particular formulation type which may be used for various active ingredients, the main classification is the relevant A01N25/xx group (without A01N 2300/00) with as additional combination-set the classifications for the active ingredients for which the disclosed formulation is envisaged.

In order to avoid an infinite number of additional classifications, only the most preferred second ingredients or exemplified embodiments should be classified in cases where a document discloses a multitude of active ingredients.

A special case occurs when mixtures of more than two active ingredients are disclosed: then the combination-set is given in a cascading way: for example: a document discloses a

composition comprising 3 active ingredients (A with classification A01Naa/bb, B with classification A01Nbb/cc and C with classification A01Ncc/dd and 1 specific surfactant. The following classifications are then given:

1. A01N 25/30, with A01Naa/bb, A01Nbb/cc and A01Ncc/dd in the combination-set;

2. A01Naa/bb, A01N 2300/00 with A01Nbb/cc and A01Ncc/dd in the combination-set;

3. A01Nbb/cc, A01N 2300/00 with A01Ncc/dd in the combination-set.

An example with real groups could be the following.

A document disclosing a mixture of microencapsulated neonicotinoid insectcides (imidacloprid or aectamiprid) with (non-encapsulated) pyrethroids (the latter preferably containing the synergist PBO) obtains the following classifications:

A01N 51/00, A01N 2300/00 with A01N 25/28, A01N 53/00 and A01N 43/30 in the combination-set; and
