(19/5r.ccls. or 19/6.ccls. or 19/7.ccls. or 19/8.ccls. or 19/9.ccls. or 19/10.ccls. or 19/11.ccls. or 19/12.ccls. or 19/13.ccls. or 19/14.ccls. or 19/15.ccls. or 19/16.ccls. or 19/17.ccls. or 19/18.ccls. or 19/19.ccls. or 19/20.ccls. or 19/21.ccls. or 19/22.ccls. or 19/23.ccls. or 19/24.ccls. or 19/25.ccls. or 19/26.ccls. or 19/27.ccls. or 19/28.ccls. or 19/29.ccls. or 19/30.ccls. or 19/31.ccls. or 19/32.ccls. or 19/33.ccls. or 19/34.ccls. or 19/5a.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.
