Use the links above or do an advanced search in ppubs for:
(213/40r.ccls. or 213/41.ccls. or 213/42.ccls. or 213/43.ccls. or 213/44.ccls. or 213/45.ccls. or 213/46r.ccls. or 213/46a.ccls. or 213/47.ccls. or 213/48.ccls. or 213/49.ccls. or 213/40d.ccls. or 213/40s.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.
