CIPO searches
search just 182/78- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((182/78 <IN> CPC) <OR> (182/79 <IN> CPC) <OR> (182/80 <IN> CPC) <OR> (182/81 <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.
