CPC Definition - Subclass A01H
This place covers:
New non-transgenic plants (including multicellular algae, multicellular fungi and lichens), plant varieties, plant tissue culture and breeding methods, methods for altering phenotypes.
Attention is drawn to the following places, which may be of interest for search:
Influencing the growth of plants without producing new plants, non-chemically. | |
Influencing the growth of plants without producing new plants, chemically. | |
Unicellular algae | |
Fungal microorganisms | |
Culture media for undifferentiated plant cell or plant tissue culture | |
Undifferentiated plant cells or tissues per se | |
Nucleic acid hybridisation assays, detecting genotypes |
A01H groups and subgroups are globally directed to tissue culture and classical breeding techniques and C12N 15/82 subgroups to transgenics. However the two are not mutually exclusive. For example traits which have been identified and used in transgenics may warrant classification in both areas, as may regeneration methods which are part of a transformation protocol.
Main groups A01H 5/00 - A01H 17/00 are only used for new, non-transgenic, plants (usually varieties)
This place covers:
Breeding methods as further defined by the sub-groups.
Plants characterized by non-agronomic quality traits, agronomic yield or resistance aspects.
This place does not cover:
Plant reproduction by tissue culture techniques |
This place covers:
Inter alia creation of hybrids, interspecific crossing, genic (e.g. male or female A01H 1/022 - A01H 1/024) and nongenic (e.g. by using chemicals A01H 1/026) sterility systems; Apparatus for pollination in A01H 1/027.

This place covers:
Inter alia marker assisted breeding ; specific allelic combination. Methods of using phenotypic markers for selection, where the trait(s) are outside of the scope of the output or input traits listed in A01H 1/10 – A01H 1/129.

This place covers:
Flower development or morphology, resistance to pathogens, climate, herbicide or hormone-influenced development.
This place covers:
Inter alia methods for modifying phenotypes as further defined by subclasses.

Looping references between A01H 13/00 and C12N 1/12 have been identified. Until this inconsistency is resolved in IPC, the current classification practice in CPC is as follows:
From the perspective of A01H 13/00, the reference C12N 1/12 is limiting. From the perspective of C12N 1/12, A01H 13/00 is application oriented.
This place covers:
New non-transgenic fungi or lichens
Looping references between A01H 15/00 and C12N 1/14 have been identified. Until this inconsistency is resolved in IPC, the current classification practice in CPC is as follows:
From the perspective of A01H 15/00, the reference C12N 1/14 is limiting. From the perspective of C12N 1/14, A01H 15/00 is application oriented.
This place covers:
New non-transgenic symbiotic or parasitic combinations including one or more new plants
