 C12

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]
 C12Q
MEASURING OR TESTING PROCESSES INVOLVING ENZYMES OR MICRO-ORGANISMS (immunoassay G01N 33/54); COMPOSITIONS OR TEST PAPERS THEREFOR; PROCESSES OF PREPARING SUCH COMPOSITIONS; CONDITION-RESPONSIVE CONTROL IN MICROBIOLOGICAL OR ENZYMOLOGICAL PROCESSES  [3]
 C12Q

Note(s)

  1. The term "involving", when used in relation to a substance, includes the testing for the substance as well as employing the substance as a determinant or reactant in a test for a different substance. Test media are classified with the relevant test process. [3]
  2. Inventions dealing with the observation of the progress or of the result of processes specified in this sub-class by any of the methods specified in sub-class G01N 3/00-G01N 29/00, are dealt with in sub-class G01N[3]
