CIPO searches
search just 165/43- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((165/43 <IN> CPC) <OR> (165/44 <IN> CPC) <OR> (165/45 <IN> CPC) <OR> (165/46 <IN> CPC) <OR> (165/47 <IN> CPC) <OR> (165/48 <IN> CPC) <OR> (165/49 <IN> CPC) <OR> (165/50 <IN> CPC) <OR> (165/51 <IN> CPC) <OR> (165/52 <IN> CPC) <OR> (165/53 <IN> CPC) <OR> (165/54 <IN> CPC) <OR> (165/55 <IN> CPC) <OR> (165/56 <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.
