CIPO searches
search just 182/1- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((182/1 <IN> CPC) <OR> (182/2 <IN> CPC) <OR> (182/2.1 <IN> CPC) <OR> (182/2.5 <IN> CPC) <OR> (182/3 <IN> CPC) <OR> (182/4 <IN> CPC) <OR> (182/5 <IN> CPC) <OR> (182/6 <IN> CPC) <OR> (182/6.5 <IN> CPC) <OR> (182/7 <IN> CPC) <OR> (182/8 <IN> CPC) <OR> (182/9 <IN> CPC) <OR> (182/10 <IN> CPC) <OR> (182/11 <IN> CPC) <OR> (182/12 <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.
