Use the links above or do an advanced search in ppubs for:
(2/431.ccls. or 2/432.ccls. or 2/433.ccls. or 2/434.ccls. or 2/435.ccls. or 2/436.ccls. or 2/437.ccls. or 2/438.ccls. or 2/439.ccls. or 2/440.ccls. or 2/441.ccls. or 2/442.ccls. or 2/443.ccls. or 2/444.ccls. or 2/445.ccls. or 2/446.ccls. or 2/447.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.
