Use the links above or do an advanced search in ppubs for:
(141/144.ccls. or 141/145.ccls. or 141/146.ccls. or 141/147.ccls. or 141/148.ccls. or 141/149.ccls. or 141/150.ccls. or 141/151.ccls. or 141/152.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.
