Use the links above or do an advanced search in ppubs for:
(226/24.ccls. or 226/25.ccls. or 226/26.ccls. or 226/27.ccls. or 226/28.ccls. or 226/29.ccls. or 226/30.ccls. or 226/31.ccls. or 226/32.ccls. or 226/33.ccls. or 226/34.ccls. or 226/35.ccls. or 226/36.ccls. or 226/37.ccls. or 226/38.ccls. or 226/39.ccls. or 226/40.ccls. or 226/41.ccls. or 226/42.ccls. or 226/43.ccls. or 226/44.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.
