CIPO searches
search just 355/28- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((355/28 <IN> CPC) <OR> (355/29 <IN> CPC) <OR> (355/30 <IN> CPC) <OR> (355/31 <IN> CPC) <OR> (355/32 <IN> CPC) <OR> (355/33 <IN> CPC) <OR> (355/34 <IN> CPC) <OR> (355/35 <IN> CPC) <OR> (355/36 <IN> CPC) <OR> (355/37 <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.
