Use the links above or do an advanced search in ppubs for:
(337/45.ccls. or 337/46.ccls. or 337/47.ccls. or 337/48.ccls. or 337/49.ccls. or 337/50.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.
