CIPO searches
search just 154/18- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/18 <IN> CPC) <OR> (154/18.5 <IN> CPC) <OR> (154/18.6 <IN> CPC) <OR> (154/18.7 <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.
