Use the links above or do an advanced search in ppubs for:
(396/32.ccls. or 396/33.ccls. or 396/34.ccls. or 396/35.ccls. or 396/36.ccls. or 396/37.ccls. or 396/38.ccls. or 396/39.ccls. or 396/40.ccls. or 396/41.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.
