Use the links above or do an advanced search in ppubs for:
(160/174r.ccls. or 160/174v.ccls. or 160/175.ccls. or 160/176.1r.ccls. or 160/176.1p.ccls. or 160/176.1v.ccls. or 160/177r.ccls. or 160/177v.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.
