CIPO searches
search just 183/83- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((183/83 <IN> CPC) <OR> (183/84 <IN> CPC) <OR> (183/85 <IN> CPC) <OR> (183/86 <IN> CPC) <OR> (183/87 <IN> CPC) <OR> (183/88 <IN> CPC) <OR> (183/89 <IN> CPC) <OR> (183/90 <IN> CPC) <OR> (183/91 <IN> CPC) <OR> (183/92 <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.
