Use the links above or do an advanced search in ppubs for:
(473/102.ccls. or 473/103.ccls. or 473/104.ccls. or 473/105.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.
