Use the links above or do an advanced search in ppubs for:
(2/456.ccls. or 2/457.ccls. or 2/458.ccls. or 2/2.11.ccls. or 2/2.12.ccls. or 2/2.13.ccls. or 2/2.14.ccls. or 2/2.15.ccls. or 2/2.16.ccls. or 2/2.17.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.
