Use the links above or do an advanced search in ppubs for:
(160/168.1r.ccls. or 160/168.1p.ccls. or 160/168.1v.ccls. or 160/169.ccls. or 160/170.ccls. or 160/171.ccls. or 160/172r.ccls. or 160/172v.ccls. or 160/173r.ccls. or 160/173v.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.
