CIPO searches
search just 154/71- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/71 <IN> CPC) <OR> (154/71.01 <IN> CPC) <OR> (154/71.02 <IN> CPC) <OR> (154/71.03 <IN> CPC) <OR> (154/71.04 <IN> CPC) <OR> (154/71.05 <IN> CPC) <OR> (154/71.06 <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.
