DEFINITION

Classification: 435/29

Involving viable microorganism:

(under subclass 4) Subject matter where the material to be tested contains a microorganism or the agent used for the measurement or test contains a microorganism.

(1) Note. A microorganism for the purposes of this subclass includes actinomycetates, unicellular algae, bacteria, fungi (including yeast), plant cells, and animal cells.

(2) Note. If there is no clear disclosure as to whether the microorganism or cell is viable or nonliving, it shall be presumed to be viable and therefore appropriate for this or the indented subclasses. However, due to the uncertainty of the viability of the microorganism or cell, placement of a cross reference in the most appropriate place in this class, subclasses 40.5+ for nonliving microorganisms or cells is strongly recommended.

40.5+, for measuring or testing processes involving fixed or stabilized nonliving microorganisms, cells, or tissues.
