Use the links above or do an advanced search in ppubs for:
(19/80r.ccls. or 19/81.ccls. or 19/82.ccls. or 19/83.ccls. or 19/84.ccls. or 19/85.ccls. or 19/86.ccls. or 19/87.ccls. or 19/88.ccls. or 19/89.ccls. or 19/90.ccls. or 19/91.ccls. or 19/92.ccls. or 19/93.ccls. or 19/94.ccls. or 19/95.ccls. or 19/96.ccls. or 19/97.ccls. or 19/97.5.ccls. or 19/80a.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.
