Use the links above or do an advanced search in ppubs for:
(122/140.1.ccls. or 122/140.2.ccls. or 122/141.ccls. or 122/142.ccls. or 122/143.ccls. or 122/144.ccls. or 122/145.ccls. or 122/146.ccls. or 122/147.ccls. or 122/148.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.
