CIPO searches
search just 92/34- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((92/34 <IN> CPC) <OR> (92/37 <IN> CPC) <OR> (92/38 <IN> CPC) <OR> (92/39 <IN> CPC) <OR> (92/40 <IN> CPC) <OR> (92/41 <IN> CPC) <OR> (92/42 <IN> CPC) <OR> (92/43 <IN> CPC) <OR> (92/51 <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.
