CIPO searches
search just 311/13- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((311/13 <IN> CPC) <OR> (311/14 <IN> CPC) <OR> (311/15 <IN> CPC) <OR> (311/16 <IN> CPC) <OR> (311/17 <IN> CPC) <OR> (311/18 <IN> CPC) <OR> (311/19 <IN> CPC) <OR> (311/20 <IN> CPC) <OR> (311/21 <IN> CPC) <OR> (311/22 <IN> CPC) <OR> (311/23 <IN> CPC) <OR> (311/24 <IN> CPC) <OR> (311/25 <IN> CPC) <OR> (311/26 <IN> CPC) <OR> (311/27 <IN> CPC) <OR> (311/28 <IN> CPC) <OR> (311/29 <IN> CPC) <OR> (311/30 <IN> CPC) <OR> (311/31 <IN> CPC) <OR> (311/32 <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.
