Use the links above or do an advanced search in ppubs for:
(188/9.ccls. or 188/10.ccls. or 188/11.ccls. or 188/12.ccls. or 188/13.ccls. or 188/14.ccls. or 188/15.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.
