Use the links above or do an advanced search in ppubs for:
(194/239.ccls. or 194/240.ccls. or 194/241.ccls. or 194/242.ccls. or 194/243.ccls. or 194/244.ccls. or 194/245.ccls. or 194/246.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.
