Use the links above or do an advanced search in ppubs for:
(510/214.ccls. or 510/215.ccls. or 510/216.ccls. or 510/217.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.
