CIPO searches
search just 154/123- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/123 <IN> CPC) <OR> (154/123.1 <IN> CPC) <OR> (154/123.2 <IN> CPC) <OR> (154/123.3 <IN> CPC) <OR> (154/123.4 <IN> CPC) <OR> (154/123.5 <IN> CPC) <OR> (154/123.6 <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.
