CIPO searches
search just 183/38- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((183/38 <IN> CPC) <OR> (183/40 <IN> CPC) <OR> (183/41 <IN> CPC) <OR> (183/42 <IN> CPC) <OR> (183/43 <IN> CPC) <OR> (183/44 <IN> CPC) <OR> (183/45 <IN> CPC) <OR> (183/46 <IN> CPC) <OR> (183/47 <IN> CPC) <OR> (183/48 <IN> CPC) <OR> (183/49 <IN> CPC) <OR> (183/50 <IN> CPC) <OR> (183/56 <IN> CPC) <OR> (183/57 <IN> CPC) <OR> (183/58 <IN> CPC) <OR> (183/59 <IN> CPC) <OR> (183/60 <IN> CPC) <OR> (183/61 <IN> CPC) <OR> (183/62 <IN> CPC) <OR> (183/63 <IN> CPC) <OR> (183/64 <IN> CPC) <OR> (183/65 <IN> CPC) <OR> (183/66 <IN> CPC) <OR> (183/67 <IN> CPC) <OR> (183/68 <IN> CPC) <OR> (183/69 <IN> CPC) <OR> (183/70 <IN> CPC) <OR> (183/71 <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.
