DEFINITION

Classification: 210/601

Treatment by living organism:

(under subclass 600) Process in which the treatment is effected by an agent which has the ability to reproduce itself.

(1) Note. For purposes of this subclass, living organism includes animals, plants, and micro-organisms (e.g., bacteria, fungus, algae, etc.) but not enzymes. The organism may reproduce either sexually, asexually, or by mechanical division (caused by external agents) and regeneration (e.g., layering or cloning, etc.).
