CIPO searches
search just 68/7- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((68/7 <IN> CPC) <OR> (68/8 <IN> CPC) <OR> (68/9 <IN> CPC) <OR> (68/10 <IN> CPC) <OR> (68/11 <IN> CPC) <OR> (68/12 <IN> CPC) <OR> (68/13 <IN> CPC) <OR> (68/14 <IN> CPC) <OR> (68/15 <IN> CPC) <OR> (68/16 <IN> CPC) <OR> (68/17 <IN> CPC) <OR> (68/18 <IN> CPC) <OR> (68/19 <IN> CPC) <OR> (68/20 <IN> CPC) <OR> (68/21 <IN> CPC) <OR> (68/22 <IN> CPC) <OR> (68/23 <IN> CPC) <OR> (68/24 <IN> CPC) <OR> (68/25 <IN> CPC) <OR> (68/26 <IN> CPC) <OR> (68/27 <IN> CPC) <OR> (68/28 <IN> CPC) <OR> (68/29 <IN> CPC) <OR> (68/30 <IN> CPC) <OR> (68/31 <IN> CPC) <OR> (68/32 <IN> CPC) <OR> (68/33 <IN> CPC) <OR> (68/34 <IN> CPC) <OR> (68/35 <IN> CPC) <OR> (68/36 <IN> CPC) <OR> (68/37 <IN> CPC) <OR> (68/38 <IN> CPC) <OR> (68/39 <IN> CPC) <OR> (68/40 <IN> CPC) <OR> (68/41 <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.
