Use the links above or do an advanced search in ppubs for:
(712/32.ccls. or 712/33.ccls. or 712/34.ccls. or 712/35.ccls. or 712/36.ccls. or 712/37.ccls. or 712/38.ccls. or 712/39.ccls. or 712/40.ccls. or 712/41.ccls. or 712/42.ccls. or 712/43.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.
