Use the links above or do an advanced search in ppubs for:
(26/29r.ccls. or 26/30.ccls. or 26/31.ccls. or 26/32.ccls. or 26/33.ccls. or 26/34.ccls. or 26/35.ccls. or 26/36.ccls. or 26/37.ccls. or 26/29p.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.
