Use the links above or do an advanced search in ppubs for:
(60/204.ccls. or 60/205.ccls. or 60/206.ccls. or 60/207.ccls. or 60/208.ccls. or 60/209.ccls. or 60/210.ccls. or 60/211.ccls. or 60/212.ccls. or 60/213.ccls. or 60/214.ccls. or 60/215.ccls. or 60/216.ccls. or 60/217.ccls. or 60/218.ccls. or 60/219.ccls. or 60/220.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.
