Use the links above or do an advanced search in ppubs for:
(180/6.24.ccls. or 180/6.26.ccls. or 180/6.28.ccls. or 180/6.3.ccls. or 180/6.32.ccls. or 180/6.34.ccls. or 180/6.36.ccls. or 180/6.38.ccls. or 180/6.4.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.
