Use the links above or do an advanced search in ppubs for:
(370/203.ccls. or 370/204.ccls. or 370/205.ccls. or 370/206.ccls. or 370/207.ccls. or 370/208.ccls. or 370/209.ccls. or 370/210.ccls. or 370/211.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.
