INDEXING SCHEME ASSOCIATED WITH SUBCLASSES , RELATING TO MICROORGANISMS

Description

C12R is an indexing scheme that organizes microorganisms used in biochemical, fermentation, and biotechnological processes according to their taxonomic or functional characteristics. This classification facilitates cross-referencing of patent documents across other C12 subclasses (such as fermentation, enzyme production, and genetic engineering) by identifying the specific microorganism or microbial type involved. It serves as a supplementary classification tool rather than a standalone subject matter classification, enabling systematic retrieval of patents involving particular microorganisms in beer production, vinegar manufacturing, wine fermentation, enzyme engineering, and mutation/genetic modification contexts.
