Use the links above or do an advanced search in ppubs for:
(266/148.ccls. or 266/149.ccls. or 266/150.ccls. or 266/151.ccls. or 266/152.ccls. or 266/153.ccls. or 266/154.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.
