Use the links above or do an advanced search in ppubs for:
(43/44.92.ccls. or 43/44.93.ccls. or 43/44.94.ccls. or 43/44.95.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.
