(368/168.ccls. or 368/169.ccls. or 368/170.ccls. or 368/171.ccls. or 368/172.ccls. or 368/173.ccls. or 368/174.ccls. or 368/175.ccls. or 368/176.ccls. or 368/177.ccls. or 368/178.ccls. or 368/179.ccls. or 368/180.ccls. or 368/181.ccls. or 368/182.ccls. or 368/183.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.
