CIPO searches
search just 225/24- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((225/24 <IN> CPC) <OR> (225/25 <IN> CPC) <OR> (225/26 <IN> CPC) <OR> (225/27 <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.
