Use the links above or do an advanced search in ppubs for:
(726/26.ccls. or 726/27.ccls. or 726/28.ccls. or 726/29.ccls. or 726/30.ccls. or 726/31.ccls. or 726/32.ccls. or 726/33.ccls.)
This will show what classes derive from the input. Ex: entering 43/42.24 shows the derived classes and the search that can be used to find patents or patent applications in those subclasses.
