(194/215.ccls. or 194/216.ccls. or 194/217.ccls. or 194/218.ccls. or 194/219.ccls. or 194/220.ccls. or 194/221.ccls. or 194/222.ccls. or 194/223.ccls. or 194/224.ccls. or 194/225.ccls. or 194/226.ccls. or 194/227.ccls. or 194/228.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.
