Use the links above or do an advanced search in ppubs for:
(215/307.ccls. or 215/308.ccls. or 215/309.ccls. or 215/310.ccls. or 215/311.ccls. or 215/312.ccls. or 215/313.ccls. or 215/314.ccls. or 215/315.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.
