Use the links above or do an advanced search in ppubs for:
(82/124.ccls. or 82/125.ccls. or 82/126.ccls. or 82/127.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.
