The "search hierarchy!" link will execute this search:
((238/141 <IN> CPC) <OR> (238/142 <IN> CPC) <OR> (238/143 <IN> CPC) <OR> (238/144 <IN> CPC) <OR> (238/145 <IN> CPC) <OR> (238/146 <IN> CPC) <OR> (238/147 <IN> CPC) <OR> (238/148 <IN> CPC) <OR> (238/149 <IN> CPC) <OR> (238/150 <IN> CPC) <OR> (238/151 <IN> CPC) <OR> (238/152 <IN> CPC) <OR> (238/153 <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.
