Use the links above or do an advanced search in ppubs for:
(PLT/216.ccls. or PLT/217.ccls. or PLT/218.ccls. or PLT/219.ccls. or PLT/220.ccls. or PLT/221.ccls. or PLT/222.ccls. or PLT/223.ccls. or PLT/224.ccls. or PLT/225.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.
