NOTE

  • This subclass covers the production of compounds or compositions by biochemical transformation of matter performed by using enzymes or micro-organisms, wherein micro-organisms are defined as any single-celled organisms, including bacteria, fungi, yeast or microalgae, or plant or mammalian cells in the form of cell cultures.
  • In this subclass, documents are primarily classified according to the compounds produced. In addition, if appropriate, classification according to the method or biocatalyst used to produce the compound is made.
  • Classification in groups C12P 19/14 - C12P 19/24, C12P 39/00, C12P 41/00 - C12P 41/009 should only be made together with the corresponding product groups
WARNING

  • The following IPC groups are not used in the CPC scheme. Subject-matter covered by these groups is classified in the following CPC groups:
    - C12P21/04 covered by C07K 7/50
