Use the links above or do an advanced search in ppubs for:
(368/52.ccls. or 368/53.ccls. or 368/54.ccls. or 368/55.ccls. or 368/56.ccls. or 368/57.ccls. or 368/58.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.
