CIPO searches
search just 225/5- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((225/5 <IN> CPC) <OR> (225/6 <IN> CPC) <OR> (225/7 <IN> CPC) <OR> (225/8 <IN> CPC) <OR> (225/9 <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.
