Use the links above or do an advanced search in ppubs for:
(355/122.ccls. or 355/123.ccls. or 355/124.ccls. or 355/125.ccls. or 355/126.ccls. or 355/127.ccls. or 355/128.ccls. or 355/129.ccls. or 355/130.ccls. or 355/131.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.
