Use the links above or do an advanced search in ppubs for:
(370/352.ccls. or 370/353.ccls. or 370/354.ccls. or 370/355.ccls. or 370/356.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.
