Use the links above or do an advanced search in ppubs for:
(184/39.ccls. or 184/39.1.ccls. or 184/40.ccls. or 184/41.ccls. or 184/42.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.
