CIPO searches
search just 92/56- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((92/56 <IN> CPC) <OR> (92/57 <IN> CPC) <OR> (92/57.1 <IN> CPC) <OR> (92/57.2 <IN> CPC) <OR> (92/57.3 <IN> CPC) <OR> (92/57.4 <IN> CPC) <OR> (92/58 <IN> CPC) <OR> (92/59 <IN> CPC) <OR> (92/60 <IN> CPC) <OR> (92/60.1 <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.
