Note(s)

  1. In the field of sub-classes C12M-C12Q, in the absence of an indication to the contrary, an invention is classified in the last appropriate place. [3]
  2. Within this class, viruses, undifferentiated plant or animal cells, protozoa and unicellular algae are considered as micro-organisms. Also, sub-cellular parts, unless specifically provided for, are classified with the whole cell. [3]
  3. Within this class, non-obligatory classifications may be given as additional information relating to the micro-organisms used by means of the symbols of sub-class C12R[3]
