CIPO searches
search just 112/42- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((112/42 <IN> CPC) <OR> (112/43 <IN> CPC) <OR> (112/44 <IN> CPC) <OR> (112/45 <IN> CPC) <OR> (112/46 <IN> CPC) <OR> (112/47 <IN> CPC) <OR> (112/48 <IN> CPC) <OR> (112/49 <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.
