Use the links above or do an advanced search in ppubs for:
(111/178.ccls. or 111/179.ccls. or 111/180.ccls. or 111/181.ccls. or 111/182.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.
