Use the links above or do an advanced search in ppubs for:
(434/1.ccls. or 434/2.ccls. or 434/3.ccls. or 434/4.ccls. or 434/5.ccls. or 434/6.ccls. or 434/7.ccls. or 434/8.ccls. or 434/9.ccls. or 434/10.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.
