Use the links above or do an advanced search in ppubs for:
(128/201.23.ccls. or 128/201.24.ccls. or 128/201.25.ccls. or 128/201.26.ccls. or 128/201.27.ccls. or 128/201.28.ccls. or 128/201.29.ccls. or 128/202.11.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.
