The "search hierarchy!" link will execute this search:
((270/129 <IN> CPC) <OR> (270/130 <IN> CPC) <OR> (270/131 <IN> CPC) <OR> (270/132 <IN> CPC) <OR> (270/133 <IN> CPC) <OR> (270/134 <IN> CPC) <OR> (270/135 <IN> CPC) <OR> (270/136 <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.
