CIPO searches
search just 183/93- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((183/93 <IN> CPC) <OR> (183/94 <IN> CPC) <OR> (183/95 <IN> CPC) <OR> (183/96 <IN> CPC) <OR> (183/97 <IN> CPC) <OR> (183/98 <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.
