Use the links above or do an advanced search in ppubs for:
(96/18.ccls. or 96/19.ccls. or 96/20.ccls. or 96/21.ccls. or 96/22.ccls. or 96/23.ccls. or 96/24.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.
