CIPO searches
search just 70/5- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((70/5 <IN> CPC) <OR> (70/6 <IN> CPC) <OR> (70/7 <IN> CPC) <OR> (70/8 <IN> CPC) <OR> (70/9 <IN> CPC) <OR> (70/10 <IN> CPC) <OR> (70/11 <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.
