search hierarchy!

The "search hierarchy!" link will execute this search:
((70/40 <IN> CPC) <OR> (70/41 <IN> CPC) <OR> (70/42 <IN> CPC) <OR> (70/43 <IN> CPC) <OR> (70/44 <IN> CPC) <OR> (70/45 <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.
