Use the links above or do an advanced search in ppubs for:
(546/16.ccls. or 546/17.ccls. or 546/18.ccls. or 546/19.ccls. or 546/20.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.
