Use the links above or do an advanced search in ppubs for:
(368/71.ccls. or 368/72.ccls. or 368/73.ccls. or 368/74.ccls. or 368/75.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.
