CIPO searches
search just 182/32- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((182/32 <IN> CPC) <OR> (182/33 <IN> CPC) <OR> (182/34 <IN> CPC) <OR> (182/35 <IN> CPC) <OR> (182/36 <IN> CPC) <OR> (182/37 <IN> CPC) <OR> (182/38 <IN> CPC) <OR> (182/39 <IN> CPC) <OR> (182/40 <IN> CPC) <OR> (182/41 <IN> CPC) <OR> (182/42 <IN> CPC) <OR> (182/43 <IN> CPC) <OR> (182/44 <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.
