Special rules of classification

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)

Particular plant taxons may be cross-classified in the subgroup of A01H 5/00A01H 5/12 corresponding to the plant part and cross-classified in the subgroup of A01H 6/00A01H 6/88, A01H 7/00A01H 17/00 according to plant taxon.

Definition statement

This place covers:

Breeding methods as further defined by the sub-groups.

Special rules of classification

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.

Definition statement

This place covers:

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.
