Use the links above or do an advanced search in ppubs for:
(226/127.ccls. or 226/128.ccls. or 226/129.ccls. or 226/130.ccls. or 226/131.ccls. or 226/132.ccls. or 226/133.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.
