Use the links above or do an advanced search in ppubs for:
(D14/489.ccls. or D14/490.ccls. or D14/491.ccls. or D14/492.ccls. or D14/493.ccls. or D14/494.ccls. or D14/495.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.
