Note(s)

  1. In subclasses C12M to Q and within each of these subclasses, in the absence of an indication to the contrary, an invention is classified in the last appropriate place. [3]
  2. In 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. In this class, it is desirable to add, in conformity with paragraph 83 of the Guide, after the double oblique stroke, the indexing codes of subclass C12R (see Note (1) following the title of subclass C12R). [3]
