Use the links above or do an advanced search in ppubs for:
(415/159.ccls. or 415/160.ccls. or 415/161.ccls. or 415/162.ccls. or 415/163.ccls. or 415/164.ccls. or 415/165.ccls. or 415/166.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.
