Use the links above or do an advanced search in ppubs for:
(368/76.ccls. or 368/77.ccls. or 368/78.ccls. or 368/79.ccls. or 368/80.ccls. or 368/81.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.
