Use the links above or do an advanced search in ppubs for:
(313/402.ccls. or 313/403.ccls. or 313/404.ccls. or 313/405.ccls. or 313/406.ccls. or 313/407.ccls. or 313/408.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.
