Use the links above or do an advanced search in ppubs for:
(347/120.ccls. or 347/121.ccls. or 347/122.ccls. or 347/123.ccls. or 347/124.ccls. or 347/125.ccls. or 347/126.ccls. or 347/127.ccls. or 347/128.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.
