Use the links above or do an advanced search in ppubs for:
(49/104.ccls. or 49/105.ccls. or 49/106.ccls. or 49/107.ccls. or 49/108.ccls. or 49/109.ccls. or 49/110.ccls. or 49/111.ccls. or 49/112.ccls. or 49/113.ccls. or 49/114.ccls. or 49/115.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.
