CIPO searches
search just 361/21- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((361/21 <IN> CPC) <OR> (361/22 <IN> CPC) <OR> (361/23 <IN> CPC) <OR> (361/24 <IN> CPC) <OR> (361/25 <IN> CPC) <OR> (361/26 <IN> CPC) <OR> (361/27 <IN> CPC) <OR> (361/28 <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.
