CIPO searches
search just 165/5- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((165/5 <IN> CPC) <OR> (165/6 <IN> CPC) <OR> (165/7 <IN> CPC) <OR> (165/8 <IN> CPC) <OR> (165/9 <IN> CPC) <OR> (165/10 <IN> CPC) <OR> (165/11 <IN> CPC) <OR> (165/12 <IN> CPC) <OR> (165/13 <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.
