Definition statement
This subclass/group covers:
  • Lubricant, i.e. a substance introduced to reduce friction between moving surfaces, which may be in the liquid, gaseous or solid form. The lubricating composition may be an emulsion, an aerosol, a grease, a dispersion of solid lubricants, a multi layer coating or composite material.
  • Use of at least one compound as a lubricant or in a lubricating composition
  • Working-up of used lubricants to recover useful products.
  • Special method of preparation of lubricating oil compositions. Chemical after treatment of components or the whole composition.

Lubricating compositions may have three types of essential ingredients: Base-Materials (main ingredient of the lubricating composition), Thickeners (used for preparing grease compositions) and Additives.

The total concentration of additives is normally up to 10 wt.% based on the whole amount of the lubricating composition. Exception may be found with viscosity-index improvers. The additives are used to enhance the performance characteristics of the base oil.

Relationship between large subject matter areas

The mechanical aspect of the lubrication conditions, places, apparatuses where the lubrication takes place are classified in section F of the European Patent Classification

Special rules of classification within this subclass

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

When only the base material(s) is(are) essential, C10M 101/00-C10M 111/00 are to be considered. When only the thickener(s) is(are) essential, C10M 113/00-C10M 123/00 are relevant. Compositions comprising essential additive(s) are in C10M 125/00-C10M 167/00. Mixtures of base-materials, thickeners and additives (at least two of them being essential) are covered by C10M 169/00. Compositions characterized by physical properties should be classified in C10M 171/00. Aqueous compositions (more than 10% water) are in C10M 173/00. Working-up of used lubricants is found in C10M 175/00. Preparation or after-treatment is covered by C10M 177/00.

Symbols chosen from C10M, C10N are mandatory and are used to classify additional information.

C10M is used to classify each component of the compositions, whether they are essential or not. Each of the components of the mixtures covered by C10M 111/00, C10M 123/00, C10M 141/00, C10M 157/00, C10M 161/00, C10M 163/00, C10M 165/00, C10M 167/00, C10M 169/00 should be classified by using the corresponding symbol. In C10M the symbols are listed with respect to their chemical structure (inorganic compounds, organic hydrocarbons, organic compounds comprising H, C and O, organic compounds comprising N, organic compounds comprising N, organic compounds comprising P, organic compounds comprising other atoms).

Combinations of symbols chosen from C10M, C10N are used in a C-set for classifying well-defined polymers. A polymer of ethylene and acrylate may be classified with C10M 2205/022,C10M 2209/084, using the alphanumerical order.

Combinations of symbols chosen from C10M, C10N are used in a C-set for classifying a specific ingredient having a specific parameter. A Group III base oil (base oil having a viscosity index of 120 or more and comprising 0.03 % or less sulfur and 90% or more saturates) is classified with C10M 2203/1025,C10N 2220/022.

A specific salt may be indexed by using a combination of symbols chosen from C10M, C10N in a C-set. A neutral calcium sulfonate is classified with C10M 2219/044,C10N 2210/02.

C10N is based on the IPC scheme C10N and contains more details. Subclass C10N is an indexing subclass associated with this subclass, and is for indexing features that are of interest in disclosures classified in this subclass, e.g. properties, uses or special modifications of lubricating compositions.

The groups C10N 2010/00 to C10N 2080/00 are not used any more and are replaced by C10N 2210/00 to C10N 2210/08. Those indexing codes are only used as linked codes in combination with codes chosen from subclass C10M2000/00 subgroups identifying the chemical nature of the compounds concerned.

Example: C10M 2201/084, C10N 2210/02: inorganic acids or salts containing sulfur, selenium or tellurium used as ingredients in lubricant compositions and wherein the metal present in the acids or salts is from group II, e.g. Mg, Ca, Ba, Zn, Cd, Hg.

Codes C10N 2220/301 to C10N 2220/306 are only used in association with group C10M 171/008 to provide information about the specific refrigerant.

Additional information comprises:

  • Metals and the metal of a compound (C10N 2210/00);
  • The properties of the lubricant composition or constituents thereof (C10N 2220/00, C10N 2230/00);

Lubricating compositions characterised by containing as components a mixture of at least two types of ingredient selected from base-materials, thickeners or additives, covered by the preceding groups, each of these compounds being essential
Definition statement
This subclass/group covers:

Compositions comprising at least 2 different essential ingredients:

Special rules of classification within this group

A mixture comprising a base oil, a thickener and an additive, each of them being essential is classified in C10M 169/00

Each of the components should be classified by using the Symbol referred to in the above groups.

Lubricating compositions characterised by purely physical criteria, e.g. containing as base-material, thickener or additive, ingredients which are characterised exclusively by their numerically specified physical properties, i.e. containing ingredients which are physically well-defined but for which the chemical nature is either unspecified or only very vaguely indicated ( chemically defined ingredients C10M 101/00 to C10M 169/00 ; petroleum fractions C10M 101/02 , C10M 121/02 , C10M 159/04)
Definition statement
This subclass/group covers:

Lubricating compositions characterised only by physical properties, e.g.

  • Electrorheological fluids
  • Traction fluids
  • Volatile oil, vaporous lubricants, spray
  • Coloured, dyes-containing or marker-containing lubricants
  • Lubricant compatible with refrigerants
