Note(s)

  1. This subclass covers the following subject matter, whether set forth as a composition (mixture), process of preparing the composition or process of treating using the composition:
    1. Drug or other biological compositions which are capable of:
    2. Body treating compositions generally intended for deodorising, protecting, adorning or grooming a body, e.g. cosmetics, dentifrices, tooth filling materials.
  2. Attention is drawn to the definitions of groups of chemical elements following the title of section C.
  3. Attention is drawn to the notes in class C07, for example the notes following the title of the subclass C07D, setting forth the rules for classifying organic compounds in that class, which rules are also applicable, if not otherwise indicated, to the classification of organic compounds in A61K[8]
  4. In this subclass, with the exception of group A61K 8/00, in the absence of an indication to the contrary, classification is made in the last appropriate place.
  5. Therapeutic activity of medicinal preparations is further classified in subclass A61P[7]

Note(s)

  1. A composition, i.e. a mixture of two or more components, is classified in the last of groups A61K 31/00-A61K 47/00 that provides for at least one of these components. The components may be single compounds or other single ingredients. [8]
  2. Any part of a composition which is not identified by the classification according to Note (1), and which itself is determined to be novel and non-obvious, must also be classified in the last appropriate place in groups A61K 31/00-A61K 47/00. The part can be either a single component or a composition in itself. [8]
  3. Any part of a composition which is not identified by the classification according to Note (1) or (2), and which is considered to represent information of interest for search, may also be classified in the last appropriate place in groups A61K 31/00-A61K 47/00. This can for example be the case when it is considered of interest to enable searching of compositions using a combination of classification symbols. Such non-obligatory classification should be given as "additional information". [8]
