(307/116.ccls. or 307/117.ccls. or 307/118.ccls. or 307/119.ccls. or 307/120.ccls. or 307/121.ccls. or 307/122.ccls. or 307/123.ccls. or 307/124.ccls. or 307/125.ccls. or 307/126.ccls. or 307/127.ccls. or 307/128.ccls. or 307/129.ccls. or 307/130.ccls. or 307/131.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.
