Use the links above or do an advanced search in ppubs for:
(D14/377.ccls. or D14/378.ccls. or D14/379.ccls. or D14/380.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.
