Use the links above or do an advanced search in ppubs for:
(406/191.ccls. or 406/192.ccls. or 406/193.ccls. or 406/194.ccls. or 406/195.ccls. or 406/196.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.
