Use the links above or do an advanced search in ppubs for:
(235/7r.ccls. or 235/6.ccls. or 235/8.ccls. or 235/9.ccls. or 235/10.ccls. or 235/11.ccls. or 235/12.ccls. or 235/13.ccls. or 235/14.ccls. or 235/15.ccls. or 235/16.ccls. or 235/17.ccls. or 235/18.ccls. or 235/19.ccls. or 235/20.ccls. or 235/21.ccls. or 235/22.ccls. or 235/23.ccls. or 235/24.ccls. or 235/25.ccls. or 235/26.ccls. or 235/27.ccls. or 235/28.ccls. or 235/7a.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.
