Use the links above or do an advanced search in ppubs for:
(310/75r.ccls. or 310/76.ccls. or 310/77.ccls. or 310/78.ccls. or 310/79.ccls. or 310/80.ccls. or 310/81.ccls. or 310/82.ccls. or 310/83.ccls. or 310/84.ccls. or 310/75a.ccls. or 310/75b.ccls. or 310/75c.ccls. or 310/75d.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.
