Use the links above or do an advanced search in ppubs for:
(406/62.ccls. or 406/63.ccls. or 406/64.ccls. or 406/65.ccls. or 406/66.ccls. or 406/67.ccls. or 406/68.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.
