search hierarchy!

The "search hierarchy!" link will execute this search:
((302/30 <IN> CPC) <OR> (302/31 <IN> CPC) <OR> (302/32 <IN> CPC) <OR> (302/33 <IN> CPC) <OR> (302/34 <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.
