Use the links above or do an advanced search in ppubs for:
(160/218.ccls. or 160/219.ccls. or 160/220.ccls. or 160/221.ccls. or 160/222.ccls. or 160/223.ccls. or 160/224.ccls. or 160/225.ccls. or 160/226.ccls. or 160/227.ccls. or 160/228.ccls. or 160/229.1.ccls. or 160/230.ccls. or 160/231.1.ccls. or 160/231.2.ccls. or 160/232.ccls. or 160/233.ccls. or 160/234.ccls. or 160/235.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.
