Use the links above or do an advanced search in ppubs for:
(504/313.ccls. or 504/314.ccls. or 504/315.ccls. or 504/316.ccls. or 504/317.ccls. or 504/318.ccls. or 504/319.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.
