Use the links above or do an advanced search in ppubs for:
(348/100.ccls. or 348/101.ccls. or 348/102.ccls. or 348/103.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.
