Use the links above or do an advanced search in ppubs for:
(82/152.ccls. or 82/153.ccls. or 82/154.ccls. or 82/155.ccls. or 82/156.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.
