Use the links above or do an advanced search in ppubs for:
(297/119.ccls. or 297/120.ccls. or 297/121.ccls. or 297/122.ccls. or 297/123.ccls. or 297/124.ccls. or 297/125.ccls. or 297/126.ccls. or 297/127.ccls. or 297/128.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.
