Use the links above or do an advanced search in ppubs for:
(101/153.ccls. or 101/154.ccls. or 101/155.ccls. or 101/156.ccls. or 101/157.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.
