Use the links above or do an advanced search in ppubs for:
(342/5.ccls. or 342/6.ccls. or 342/7.ccls. or 342/8.ccls. or 342/9.ccls. or 342/10.ccls. or 342/11.ccls. or 342/12.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.
