Use the links above or do an advanced search in ppubs for:
(423/702.ccls. or 423/703.ccls. or 423/704.ccls. or 423/705.ccls. or 423/706.ccls. or 423/707.ccls. or 423/708.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.
