Note(s) In the field of sub-classes Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...C12M-C12Q, in the absence of an indication to the contrary, an invention is classified in the last appropriate place. [3] 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] 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 Fulltext... Hierarchy... Expanded...C12R. [3]
