CIPO searches
search just 182/55- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((182/55 <IN> CPC) <OR> (182/56 <IN> CPC) <OR> (182/57 <IN> CPC) <OR> (182/58 <IN> CPC) <OR> (182/59 <IN> CPC) <OR> (182/60 <IN> CPC) <OR> (182/61 <IN> CPC) <OR> (182/62 <IN> CPC) <OR> (182/63 <IN> CPC) <OR> (182/64 <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.
