(435/7.2.ccls. or 435/7.21.ccls. or 435/7.22.ccls. or 435/7.23.ccls. or 435/7.24.ccls. or 435/7.25.ccls. or 435/7.3.ccls. or 435/7.31.ccls. or 435/7.32.ccls. or 435/7.33.ccls. or 435/7.34.ccls. or 435/7.35.ccls. or 435/7.36.ccls. or 435/7.37.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.
