CIPO searches
search just 154/29.08- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/29.08 <IN> CPC) <OR> (154/29.09 <IN> CPC) <OR> (154/29.1 <IN> CPC) <OR> (154/29.11 <IN> CPC) <OR> (154/29.12 <IN> CPC) <OR> (154/29.13 <IN> CPC) <OR> (154/29.14 <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.
