Use the links above or do an advanced search in ppubs for:
(347/85.ccls. or 347/86.ccls. or 347/87.ccls. or 347/88.ccls. or 347/89.ccls. or 347/90.ccls. or 347/91.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.
