Use the links above or do an advanced search in ppubs for:
(368/286.ccls. or 368/287.ccls. or 368/288.ccls. or 368/289.ccls. or 368/290.ccls. or 368/291.ccls. or 368/292.ccls. or 368/293.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.
