Use the links above or do an advanced search in ppubs for:
(54/38.1.ccls. or 54/39.1.ccls. or 54/40.1.ccls. or 54/41.1.ccls. or 54/42.1.ccls. or 54/43.1.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.
