Use the links above or do an advanced search in ppubs for:
(194/344.ccls. or 194/345.ccls. or 194/346.ccls. or 194/347.ccls. or 194/348.ccls. or 194/349.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.
