CIPO searches
search just 165/57- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((165/57 <IN> CPC) <OR> (165/58 <IN> CPC) <OR> (165/59 <IN> CPC) <OR> (165/60 <IN> CPC) <OR> (165/61 <IN> CPC) <OR> (165/62 <IN> CPC) <OR> (165/63 <IN> CPC) <OR> (165/64 <IN> CPC) <OR> (165/65 <IN> CPC) <OR> (165/66 <IN> CPC) <OR> (165/67 <IN> CPC) <OR> (165/68 <IN> CPC) <OR> (165/69 <IN> CPC) <OR> (165/70 <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.
