Use the links above or do an advanced search in ppubs for:
(604/59.ccls. or 604/60.ccls. or 604/61.ccls. or 604/62.ccls. or 604/63.ccls. or 604/64.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.
