Use the links above or do an advanced search in ppubs for:
(141/234.ccls. or 141/235.ccls. or 141/236.ccls. or 141/237.ccls. or 141/238.ccls. or 141/239.ccls. or 141/240.ccls. or 141/241.ccls. or 141/242.ccls. or 141/243.ccls. or 141/244.ccls. or 141/245.ccls. or 141/246.ccls. or 141/247.ccls. or 141/248.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.
