Use the links above or do an advanced search in ppubs for:
(361/225.ccls. or 361/226.ccls. or 361/227.ccls. or 361/228.ccls. or 361/229.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.
