CIPO searches
search just 359/27- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((359/27 <IN> CPC) <OR> (359/28 <IN> CPC) <OR> (359/29 <IN> CPC) <OR> (359/30 <IN> CPC) <OR> (359/31 <IN> CPC) <OR> (359/32 <IN> CPC) <OR> (359/33 <IN> CPC) <OR> (359/34 <IN> CPC) <OR> (359/36 <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.
