search hierarchy!

The "search hierarchy!" link will execute this search:
((70/35 <IN> CPC) <OR> (70/36 <IN> CPC) <OR> (70/37 <IN> CPC) <OR> (70/38 <IN> CPC) <OR> (70/39 <IN> CPC) <OR> (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) <OR> (70/46 <IN> CPC) <OR> (70/47 <IN> CPC) <OR> (70/48 <IN> CPC) <OR> (70/49 <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.
