Use the links above or do an advanced search in ppubs for:
(200/19.06.ccls. or 200/19.07.ccls. or 200/19.08.ccls. or 200/19.09.ccls. or 200/19.1.ccls. or 200/19.11.ccls. or 200/19.12.ccls. or 200/19.13.ccls. or 200/19.14.ccls. or 200/19.15.ccls. or 200/19.16.ccls. or 200/19.17.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.
