Use the links above or do an advanced search in ppubs for:
(707/930.ccls. or 707/931.ccls. or 707/932.ccls. or 707/933.ccls. or 707/934.ccls. or 707/935.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.
