CIPO searches
search just 25/44- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((25/44 <IN> CPC) <OR> (25/45 <IN> CPC) <OR> (25/46 <IN> CPC) <OR> (25/47 <IN> CPC) <OR> (25/48 <IN> CPC) <OR> (25/49 <IN> CPC) <OR> (25/50 <IN> CPC) <OR> (25/51 <IN> CPC) <OR> (25/52 <IN> CPC) <OR> (25/53 <IN> CPC) <OR> (25/54 <IN> CPC) <OR> (25/55 <IN> CPC) <OR> (25/56 <IN> CPC) <OR> (25/57 <IN> CPC) <OR> (25/58 <IN> CPC) <OR> (25/59 <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.
