Use the links above or do an advanced search in ppubs for:
(406/86.ccls. or 406/87.ccls. or 406/88.ccls. or 406/89.ccls. or 406/90.ccls. or 406/91.ccls. or 406/92.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.
