Use the links above or do an advanced search in ppubs for:
(205/210.ccls. or 205/211.ccls. or 205/212.ccls. or 205/213.ccls. or 205/214.ccls. or 205/215.ccls. or 205/216.ccls. or 205/217.ccls. or 205/218.ccls. or 205/219.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.
