Use the links above or do an advanced search in ppubs for:
(347/5.ccls. or 347/6.ccls. or 347/7.ccls. or 347/8.ccls. or 347/9.ccls. or 347/10.ccls. or 347/11.ccls. or 347/12.ccls. or 347/13.ccls. or 347/14.ccls. or 347/15.ccls. or 347/16.ccls. or 347/17.ccls. or 347/18.ccls. or 347/19.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.
