Use the links above or do an advanced search in ppubs for:
(D11/6.ccls. or D11/7.ccls. or D11/2.ccls. or D11/8.ccls. or D11/9.ccls. or D11/10.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.
