CIPO searches
search just 112/54- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((112/54 <IN> CPC) <OR> (112/55 <IN> CPC) <OR> (112/56 <IN> CPC) <OR> (112/57 <IN> CPC) <OR> (112/58 <IN> CPC) <OR> (112/59 <IN> CPC) <OR> (112/61 <IN> CPC) <OR> (112/62 <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.
