Use the links above or do an advanced search in ppubs for:
(150/132.ccls. or 150/133.ccls. or 150/134.ccls. or 150/135.ccls. or 150/136.ccls. or 150/137.ccls. or 150/138.ccls. or 150/139.ccls. or 150/140.ccls. or 150/141.ccls. or 150/142.ccls. or 150/143.ccls. or 150/144.ccls. or 150/145.ccls. or 150/146.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.
