Use the links above or do an advanced search in ppubs for:
(313/477r.ccls. or 313/478.ccls. or 313/479.ccls. or 313/480.ccls. or 313/481.ccls. or 313/482.ccls. or 313/477hc.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.
