Use the links above or do an advanced search in ppubs for:
(109/10.ccls. or 109/11.ccls. or 109/12.ccls. or 109/13.ccls. or 109/14.ccls. or 109/15.ccls. or 109/16.ccls. or 109/17.ccls. or 109/18.ccls. or 109/19.ccls. or 109/20.ccls. or 109/21.ccls. or 109/21.5.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.
