Use the links above or do an advanced search in ppubs for:
(455/132.ccls. or 455/133.ccls. or 455/134.ccls. or 455/135.ccls. or 455/136.ccls. or 455/137.ccls. or 455/138.ccls. or 455/139.ccls. or 455/140.ccls. or 455/141.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.
