CIPO searches
search just 359/51- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((359/51 <IN> CPC) <OR> (359/52 <IN> CPC) <OR> (359/54 <IN> CPC) <OR> (359/55 <IN> CPC) <OR> (359/56 <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.
