Class C12

SECTION C – CHEMISTRY; METALLURGY

C 12BIOCHEMISTRY; BEER; SPIRITS; WINE; VINEGAR; MICROBIOLOGY; ENZYMOLOGY; MUTATION OR GENETIC ENGINEERING

Notes

(1)In subclasses C12M to C12Q or C12S, and within each of these subclasses, in the absence of an indication to the contrary, classification is made in the last appropriate place.  [3]

(2)In this class, viruses, undifferentiated human, animal or plant cells, protozoa, tissues and unicellular algae are considered as micro-organisms.  [3,5]

(3)In this subclass, unless specifically provided for, undifferentiated human, animal or plant cells, protozoa, tissues and unicellular algae are classified together with micro-organisms. Sub-cellular parts, unless specifically provided for, are classified with the whole cell.  [5]

(4)The codes of subclass C12R are only for use as indexing codes associated with subclasses C12C to C12Q or C12S, so as to provide information concerning the micro-organisms used in the processes classified in these subclasses.  [3]
