search hierarchy!
The "search hierarchy!" link will execute this search:
((126/40 <IN> CPC) <OR> (126/41 <IN> CPC) <OR> (126/42 <IN> CPC) <OR> (126/43 <IN> CPC) <OR> (126/44 <IN> CPC) <OR> (126/45 <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.
