Use the links above or do an advanced search in ppubs for:
(297/188.14.ccls. or 297/188.15.ccls. or 297/188.16.ccls. or 297/188.17.ccls. or 297/188.18.ccls. or 297/188.19.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.
