CIPO searches
search just 225/15- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((225/15 <IN> CPC) <OR> (225/16 <IN> CPC) <OR> (225/17 <IN> CPC) <OR> (225/18 <IN> CPC) <OR> (225/19 <IN> CPC) <OR> (225/20 <IN> CPC) <OR> (225/21 <IN> CPC) <OR> (225/22 <IN> CPC) <OR> (225/23 <IN> CPC) <OR> (225/24 <IN> CPC) <OR> (225/25 <IN> CPC) <OR> (225/26 <IN> CPC) <OR> (225/27 <IN> CPC) <OR> (225/28 <IN> CPC) <OR> (225/29 <IN> CPC) <OR> (225/30 <IN> CPC) <OR> (225/31 <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.
