Use the links above or do an advanced search in ppubs for:
(307/1.ccls. or 307/2.ccls. or 307/3.ccls. or 307/4.ccls. or 307/5.ccls. or 307/6.ccls. or 307/7.ccls. or 307/8.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.
