(252/62.56.ccls. or 252/62.57.ccls. or 252/62.58.ccls. or 252/62.59.ccls. or 252/62.6.ccls. or 252/62.61.ccls. or 252/62.62.ccls. or 252/62.63.ccls. or 252/62.64.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.
