Use the links above or do an advanced search in ppubs for:
(701/71.ccls. or 701/72.ccls. or 701/73.ccls. or 701/u.ccls. or 701/74.ccls. or 701/75.ccls. or 701/76.ccls. or 701/77.ccls. or 701/78.ccls. or 701/79.ccls. or 701/80.ccls. or 701/81.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.
