CIPO searches
search just 154/55- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/55 <IN> CPC) <OR> (154/56 <IN> CPC) <OR> (154/57 <IN> CPC) <OR> (154/58 <IN> CPC) <OR> (154/59 <IN> CPC) <OR> (154/60 <IN> CPC) <OR> (154/61 <IN> CPC) <OR> (154/62 <IN> CPC) <OR> (154/63 <IN> CPC) <OR> (154/64 <IN> CPC) <OR> (154/65 <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.
