The "search hierarchy!" link will execute this search:
((307/16 <IN> CPC) <OR> (307/17 <IN> CPC) <OR> (307/18 <IN> CPC) <OR> (307/19 <IN> CPC) <OR> (307/20 <IN> CPC) <OR> (307/21 <IN> CPC) <OR> (307/22 <IN> CPC) <OR> (307/23 <IN> CPC) <OR> (307/24 <IN> CPC) <OR> (307/25 <IN> CPC) <OR> (307/26 <IN> CPC) <OR> (307/27 <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.
