Use the links above or do an advanced search in ppubs for:
(PLT/130.ccls. or PLT/131.ccls. or PLT/132.ccls. or PLT/133.ccls. or PLT/134.ccls. or PLT/135.ccls. or PLT/136.ccls. or PLT/137.ccls. or PLT/138.ccls. or PLT/139.ccls. or PLT/140.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.
