Use the links above or do an advanced search in ppubs for:
(194/294.ccls. or 194/295.ccls. or 194/296.ccls. or 194/297.ccls. or 194/298.ccls. or 194/299.ccls. or 194/300.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.
