Use the links above or do an advanced search in ppubs for:
(205/159.ccls. or 205/160.ccls. or 205/161.ccls. or 205/162.ccls. or 205/163.ccls. or 205/164.ccls. or 205/165.ccls. or 205/166.ccls. or 205/167.ccls. or 205/168.ccls. or 205/169.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.
