Use the links above or do an advanced search in ppubs for:
(270/30.01.ccls. or 270/30.02.ccls. or 270/30.03.ccls. or 270/30.04.ccls. or 270/30.05.ccls. or 270/30.06.ccls. or 270/30.07.ccls. or 270/30.08.ccls. or 270/30.09.ccls. or 270/30.1.ccls. or 270/30.11.ccls. or 270/30.12.ccls. or 270/30.13.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.
