Use the links above or do an advanced search in ppubs for:
(208/39.ccls. or 208/40.ccls. or 208/41.ccls. or 208/42.ccls. or 208/43.ccls. or 208/44.ccls. or 208/45.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.
