CIPO searches
search just 345/34- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((345/34 <IN> CPC) <OR> (345/35 <IN> CPC) <OR> (345/36 <IN> CPC) <OR> (345/37 <IN> CPC) <OR> (345/38 <IN> CPC) <OR> (345/39 <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.
