Use the links above or do an advanced search in ppubs for:
(313/17.ccls. or 313/18.ccls. or 313/19.ccls. or 313/20.ccls. or 313/21.ccls. or 313/22.ccls. or 313/23.ccls. or 313/24.ccls. or 313/25.ccls. or 313/26.ccls. or 313/27.ccls. or 313/28.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.
