CIPO searches
search just 68/4- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((68/4 <IN> CPC) <OR> (68/5 <IN> CPC) <OR> (68/6 <IN> CPC) <OR> (68/6.1 <IN> CPC) <OR> (68/6.2 <IN> CPC) <OR> (68/6.3 <IN> CPC) <OR> (68/6.4 <IN> CPC) <OR> (68/6.5 <IN> CPC) <OR> (68/6.6 <IN> CPC) <OR> (68/6.7 <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.
