(439/11.ccls. or 439/12.ccls. or 439/13.ccls. or 439/14.ccls. or 439/15.ccls. or 439/16.ccls. or 439/17.ccls. or 439/18.ccls. or 439/19.ccls. or 439/20.ccls. or 439/21.ccls. or 439/22.ccls. or 439/23.ccls. or 439/24.ccls. or 439/25.ccls. or 439/26.ccls. or 439/27.ccls. or 439/28.ccls. or 439/29.ccls. or 439/30.ccls. or 439/31.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.
