Use the links above or do an advanced search in ppubs for:
(707/944.ccls. or 707/945.ccls. or 707/946.ccls. or 707/947.ccls. or 707/948.ccls. or 707/949.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.
