CIPO searches
search just 154/8.15- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/8.15 <IN> CPC) <OR> (154/8.16 <IN> CPC) <OR> (154/8.17 <IN> CPC) <OR> (154/8.18 <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.
