Use the links above or do an advanced search in ppubs for:
(968/73.ccls. or 968/74.ccls. or 968/75.ccls. or 968/76.ccls. or 968/77.ccls. or 968/78.ccls. or 968/79.ccls. or 968/80.ccls. or 968/81.ccls. or 968/82.ccls. or 968/83.ccls. or 968/84.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.
