Use the links above or do an advanced search in ppubs for:
(370/260.ccls. or 370/261.ccls. or 370/262.ccls. or 370/263.ccls. or 370/264.ccls. or 370/265.ccls. or 370/266.ccls. or 370/267.ccls. or 370/268.ccls. or 370/269.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.
