Use the links above or do an advanced search in ppubs for:
(24/391.ccls. or 24/392.ccls. or 24/393.ccls. or 24/394.ccls. or 24/395.ccls. or 24/396.ccls. or 24/397.ccls. or 24/398.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.
