Use the links above or do an advanced search in ppubs for:
(24/17r.ccls. or 24/18.ccls. or 24/17a.ccls. or 24/17b.ccls. or 24/17ap.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.
