Use the links above or do an advanced search in ppubs for:
(24/71r.ccls. or 24/71t.ccls. or 24/71st.ccls. or 24/71tt.ccls. or 24/71sb.ccls. or 24/71a.ccls. or 24/71j.ccls. or 24/71td.ccls. or 24/71ct.ccls. or 24/71sk.ccls. or 24/71sd.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.
