The "search hierarchy!" link will execute this search:
((203/36 <IN> CPC) <OR> (203/37 <IN> CPC) <OR> (203/38 <IN> CPC) <OR> (203/39 <IN> CPC) <OR> (203/40 <IN> CPC) <OR> (203/41 <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.
