(135/143.ccls. or 135/144.ccls. or 135/145.ccls. or 135/146.ccls. or 135/147.ccls. or 135/148.ccls. or 135/149.ccls. or 135/150.ccls. or 135/151.ccls. or 135/152.ccls. or 135/153.ccls. or 135/154.ccls. or 135/155.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.
