Use the links above or do an advanced search in ppubs for:
(70/6.ccls. or 70/7.ccls. or 70/8.ccls. or 70/9.ccls. or 70/10.ccls. or 70/11.ccls. or 70/12.ccls. or 70/13.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.
