search hierarchy!
The "search hierarchy!" link will execute this search:
((119/39 <IN> CPC) <OR> (119/40 <IN> CPC) <OR> (119/41 <IN> CPC) <OR> (119/42 <IN> CPC) <OR> (119/43 <IN> CPC) <OR> (119/44 <IN> CPC))
This will show what classes derive from the input. Ex: entering 78/35 shows the derived classes and the search that can be used to find
patents in those subclasses.
