search hierarchy!
The "search hierarchy!" link will execute this search:
((154/53 <IN> CPC) <OR> (154/53.01 <IN> CPC) <OR> (154/53.02 <IN> CPC) <OR> (154/53.03 <IN> CPC) <OR> (154/53.04 <IN> CPC) <OR> (154/53.05 <IN> CPC) <OR> (154/53.06 <IN> CPC) <OR> (154/53.07 <IN> CPC) <OR> (154/53.08 <IN> CPC) <OR> (154/53.09 <IN> CPC) <OR> (154/53.1 <IN> CPC) <OR> (154/53.11 <IN> CPC) <OR> (154/53.12 <IN> CPC) <OR> (154/53.13 <IN> CPC) <OR> (154/53.14 <IN> CPC) <OR> (154/53.15 <IN> CPC) <OR> (154/53.16 <IN> CPC) <OR> (154/53.17 <IN> CPC) <OR> (154/53.18 <IN> CPC) <OR> (154/53.19 <IN> CPC) <OR> (154/53.2 <IN> CPC) <OR> (154/53.21 <IN> CPC) <OR> (154/53.22 <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.
