Use the links above or do an advanced search in ppubs for:
(119/259.ccls. or 119/260.ccls. or 119/261.ccls. or 119/262.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.
