(376/245.ccls. or 376/246.ccls. or 376/247.ccls. or 376/248.ccls. or 376/249.ccls. or 376/250.ccls. or 376/251.ccls. or 376/252.ccls. or 376/253.ccls. or 376/254.ccls. or 376/255.ccls. or 376/256.ccls. or 376/257.ccls. or 376/258.ccls. or 376/259.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.
