Use the links above or do an advanced search in ppubs for:
(60/625.ccls. or 60/626.ccls. or 60/627.ccls. or 60/628.ccls. or 60/629.ccls. or 60/630.ccls. or 60/631.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.
