Use the links above or do an advanced search in ppubs for:
(48/204.ccls. or 48/205.ccls. or 48/206.ccls. or 48/207.ccls. or 48/208.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.
