CIPO searches
search just 182/65- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((182/65 <IN> CPC) <OR> (182/66 <IN> CPC) <OR> (182/67 <IN> CPC) <OR> (182/68 <IN> CPC) <OR> (182/69 <IN> CPC) <OR> (182/70 <IN> CPC) <OR> (182/71 <IN> CPC) <OR> (182/72 <IN> CPC) <OR> (182/73 <IN> CPC) <OR> (182/74 <IN> CPC) <OR> (182/75 <IN> CPC) <OR> (182/76 <IN> CPC) <OR> (182/77 <IN> CPC) <OR> (182/78 <IN> CPC) <OR> (182/79 <IN> CPC) <OR> (182/80 <IN> CPC) <OR> (182/81 <IN> CPC) <OR> (182/82 <IN> CPC) <OR> (182/83 <IN> CPC) <OR> (182/84 <IN> CPC) <OR> (182/85 <IN> CPC) <OR> (182/86 <IN> CPC) <OR> (182/87 <IN> CPC) <OR> (182/88 <IN> CPC) <OR> (182/89 <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.
