CIPO searches
search just 68/9- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((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))
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.
