Use the links above or do an advanced search in ppubs for:
(411/285.ccls. or 411/286.ccls. or 411/287.ccls. or 411/288.ccls. or 411/289.ccls. or 411/290.ccls. or 411/291.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.
