Use the links above or do an advanced search in ppubs for:
(298/17.5.ccls. or 298/17.6.ccls. or 298/17.7.ccls. or 298/17.8.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.
