Use the links above or do an advanced search in ppubs for:
(462/39.ccls. or 462/40.ccls. or 462/41.ccls. or 462/42.ccls. or 462/43.ccls. or 462/44.ccls. or 462/45.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.
