CIPO searches
search just 183/114- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((183/114 <IN> CPC) <OR> (183/115 <IN> CPC) <OR> (183/116 <IN> CPC) <OR> (183/117 <IN> CPC) <OR> (183/118 <IN> CPC) <OR> (183/119 <IN> CPC) <OR> (183/120 <IN> CPC) <OR> (183/121 <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.
