CIPO searches
search just 154/42- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/42 <IN> CPC) <OR> (154/43 <IN> CPC) <OR> (154/44 <IN> CPC) <OR> (154/45 <IN> CPC) <OR> (154/46 <IN> CPC) <OR> (154/47 <IN> CPC) <OR> (154/48 <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.
