Use the links above or do an advanced search in ppubs for:
(310/156.38.ccls. or 310/156.39.ccls. or 310/156.41.ccls. or 310/156.42.ccls. or 310/156.43.ccls. or 310/156.44.ccls. or 310/156.45.ccls. or 310/156.46.ccls. or 310/156.47.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.
