Use the links above or do an advanced search in ppubs for:
(453/3.ccls. or 453/4.ccls. or 453/5.ccls. or 453/6.ccls. or 453/7.ccls. or 453/8.ccls. or 453/9.ccls. or 453/10.ccls. or 453/11.ccls. or 453/12.ccls. or 453/13.ccls. or 453/14.ccls. or 453/15.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.
