CIPO searches
search just 154/53.05- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/53.05 <IN> CPC) <OR> (154/53.06 <IN> CPC) <OR> (154/53.07 <IN> CPC) <OR> (154/53.08 <IN> CPC) <OR> (154/53.09 <IN> CPC) <OR> (154/53.1 <IN> CPC) <OR> (154/53.11 <IN> CPC) <OR> (154/53.12 <IN> CPC) <OR> (154/53.13 <IN> CPC) <OR> (154/53.14 <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.
