CIPO searches
search just 107/15- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((107/15 <IN> CPC) <OR> (107/16 <IN> CPC) <OR> (107/17 <IN> CPC) <OR> (107/18 <IN> CPC) <OR> (107/19 <IN> CPC) <OR> (107/20 <IN> CPC) <OR> (107/21 <IN> CPC) <OR> (107/22 <IN> CPC) <OR> (107/23 <IN> CPC) <OR> (107/24 <IN> CPC) <OR> (107/25 <IN> CPC) <OR> (107/26 <IN> CPC) <OR> (107/27 <IN> CPC) <OR> (107/28 <IN> CPC) <OR> (107/29 <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.
