Use the links above or do an advanced search in ppubs for:
(59/38.ccls. or 59/39.ccls. or 59/40.ccls. or 59/41.ccls. or 59/42.ccls. or 59/43.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.
