CIPO searches
search just 361/29- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((361/29 <IN> CPC) <OR> (361/30 <IN> CPC) <OR> (361/31 <IN> CPC) <OR> (361/32 <IN> CPC) <OR> (361/33 <IN> CPC) <OR> (361/34 <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.
