Use the links above or do an advanced search in ppubs for:
(293/149.ccls. or 293/150.ccls. or 293/151.ccls. or 293/152.ccls. or 293/153.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.
