Use the links above or do an advanced search in ppubs for:
(297/94.ccls. or 297/95.ccls. or 297/96.ccls. or 297/97.ccls. or 297/98.ccls. or 297/99.ccls. or 297/100.ccls. or 297/101.ccls. or 297/102.ccls. or 297/103.ccls. or 297/104.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.
