Use the links above or do an advanced search in ppubs for:
(226/158.ccls. or 226/159.ccls. or 226/160.ccls. or 226/161.ccls. or 226/162.ccls. or 226/163.ccls. or 226/164.ccls. or 226/165.ccls. or 226/166.ccls. or 226/167.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.
