Use the links above or do an advanced search in ppubs for:
(62/150.ccls. or 62/151.ccls. or 62/152.ccls. or 62/153.ccls. or 62/154.ccls. or 62/155.ccls. or 62/156.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.
