Use the links above or do an advanced search in ppubs for:
(24/70r.ccls. or 24/70sk.ccls. or 24/70t.ccls. or 24/70ct.ccls. or 24/70tt.ccls. or 24/70st.ccls. or 24/70j.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.
