CIPO searches
search just 359/66- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((359/66 <IN> CPC) <OR> (359/67 <IN> CPC) <OR> (359/68 <IN> CPC) <OR> (359/71 <IN> CPC) <OR> (359/72 <IN> CPC) <OR> (359/73 <IN> CPC) <OR> (359/75 <IN> CPC) <OR> (359/76 <IN> CPC) <OR> (359/77 <IN> CPC) <OR> (359/78 <IN> CPC) <OR> (359/79 <IN> CPC) <OR> (359/81 <IN> CPC) <OR> (359/82 <IN> CPC) <OR> (359/83 <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.
