COOPERATIVE PATENT CLASSIFICATION

C08K
Use of inorganic or non-macromolecular organic substances as compounding ingredients (paints, inks, varnishes, dyes, polishes, adhesives C09) [2021-01]
NOTES

  • In this subclass, in the absence of an indication to the contrary, an ingredient is classified in the last appropriate place.
  • In this subclass:
    • a mixture of ingredients is classified in the most indented group covering all the essential ingredients of the mixture, e.g.:
      • a mixture of a monohydric and a polyhydric alcohol C08K 5/05
      • a mixture of two polyhydric alcohols C08K 5/053
      • a mixture of an alcohol and an ether C08K 5/04
      • a mixture of an ether and an amine C08K 5/00
      • a mixture of an amine and a metal C08K 13/02
        {This note is applied only for mixtures with more than three essential ingredients. Mixtures with two or three ingredients are classified in the appropriate groups of C08K, e.g. a mixture of Al2O3, an ether and an amine is classified in C08K 3/22, C08K 5/06 and C08K 5/17}
    • ammonium salts are classified in the same way as metal salts
  • In this subclass, any ingredient of a mixture 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 according to Note (1). The ingredient can be either a single compound or a composition in itself. ".{This IPC Note does not apply in CPC}
  • Any ingredient of a mixture 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 according to Note (1). This can, for example, be the case when it is considered of interest to enable searching of mixtures using a combination of classification symbols. Such non-obligatory classification should be given as "additional information".{This IPC Note does not apply in CPC}
  • {In this subclass, combination sets [C-Sets] are used. The detailed information about the C-Sets construction and the associated syntax rules is present in the definitions of C08K}
  • {In this subclass, organic acid salts, alcoholates, phenolates or mercaptides are classified in the groups or subgroups of the parent compounds}
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
