Use the links above or do an advanced search in ppubs for:
(348/144.ccls. or 348/145.ccls. or 348/146.ccls. or 348/147.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.
