CIPO searches
search just 183/78- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((183/78 <IN> CPC) <OR> (183/79 <IN> CPC) <OR> (183/80 <IN> CPC) <OR> (183/81 <IN> CPC) <OR> (183/82 <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.
