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 - C12P21/08 covered by C07K 16/00
