CIPO searches
search just 112/4- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((112/4 <IN> CPC) <OR> (112/5 <IN> CPC) <OR> (112/6 <IN> CPC) <OR> (112/7 <IN> CPC) <OR> (112/8 <IN> CPC) <OR> (112/9 <IN> CPC) <OR> (112/10 <IN> CPC) <OR> (112/11 <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.
