CIPO searches
search just 361/11- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((361/11 <IN> CPC) <OR> (361/12 <IN> CPC) <OR> (361/13 <IN> CPC) <OR> (361/14 <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.
