CIPO searches
search just 345/13- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((345/13 <IN> CPC) <OR> (345/14 <IN> CPC) <OR> (345/15 <IN> CPC) <OR> (345/16 <IN> CPC) <OR> (345/17 <IN> CPC) <OR> (345/18 <IN> CPC) <OR> (345/19 <IN> CPC) <OR> (345/20 <IN> CPC) <OR> (345/21 <IN> CPC) <OR> (345/22 <IN> CPC) <OR> (345/23 <IN> CPC) <OR> (345/24 <IN> CPC) <OR> (345/25 <IN> CPC) <OR> (345/26 <IN> CPC) <OR> (345/27 <IN> CPC) <OR> (345/28 <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.
