CIPO searches
search just 129/6- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((129/6 <IN> CPC) <OR> (129/7 <IN> CPC) <OR> (129/8 <IN> CPC) <OR> (129/9 <IN> CPC) <OR> (129/10 <IN> CPC) <OR> (129/11 <IN> CPC) <OR> (129/12 <IN> CPC) <OR> (129/13 <IN> CPC) <OR> (129/14 <IN> CPC) <OR> (129/15 <IN> CPC) <OR> (129/16 <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.
