Use the links above or do an advanced search in ppubs for:
(180/182.ccls. or 180/183.ccls. or 180/184.ccls. or 180/185.ccls. or 180/186.ccls. or 180/187.ccls. or 180/188.ccls. or 180/189.ccls. or 180/190.ccls. or 180/191.ccls. or 180/192.ccls. or 180/193.ccls. or 180/194.ccls. or 180/195.ccls. or 180/196.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.
