Use the links above or do an advanced search in ppubs for:
(702/60.ccls. or 702/61.ccls. or 702/62.ccls. or 702/63.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.
