(24/31r.ccls. or 24/32.ccls. or 24/33r.ccls. or 24/33a.ccls. or 24/33f.ccls. or 24/33p.ccls. or 24/33v.ccls. or 24/33l.ccls. or 24/33b.ccls. or 24/33c.ccls. or 24/33k.ccls. or 24/33m.ccls. or 24/34.ccls. or 24/35.ccls. or 24/36.ccls. or 24/37.ccls. or 24/38.ccls. or 24/39.ccls. or 24/31b.ccls. or 24/31c.ccls. or 24/31f.ccls. or 24/31l.ccls. or 24/31h.ccls. or 24/31w.ccls. or 24/31v.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.
