The "search hierarchy!" link will execute this search:
((238/49 <IN> CPC) <OR> (238/50 <IN> CPC) <OR> (238/51 <IN> CPC) <OR> (238/52 <IN> CPC) <OR> (238/53 <IN> CPC) <OR> (238/54 <IN> CPC) <OR> (238/55 <IN> CPC) <OR> (238/56 <IN> CPC) <OR> (238/57 <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.
