Use the links above or do an advanced search in ppubs for:
(337/126.ccls. or 337/127.ccls. or 337/128.ccls. or 337/129.ccls. or 337/130.ccls. or 337/131.ccls. or 337/132.ccls. or 337/133.ccls. or 337/134.ccls. or 337/135.ccls. or 337/136.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.
