Use the links above or do an advanced search in ppubs for:
(707/966.ccls. or 707/967.ccls. or 707/968.ccls. or 707/969.ccls. or 707/970.ccls. or 707/971.ccls. or 707/972.ccls. or 707/973.ccls. or 707/974.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.
