Use the links above or do an advanced search in ppubs for:
(100/162r.ccls. or 100/163r.ccls. or 100/164.ccls. or 100/165.ccls. or 100/163a.ccls. or 100/166.ccls. or 100/162b.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.
