Use the links above or do an advanced search in ppubs for:
(310/136.ccls. or 310/137.ccls. or 310/138.ccls. or 310/139.ccls. or 310/140.ccls. or 310/141.ccls. or 310/142.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.
