CIPO searches
search just 216/1- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((216/1 <IN> CPC) <OR> (216/2 <IN> CPC) <OR> (216/3 <IN> CPC) <OR> (216/4 <IN> CPC) <OR> (216/5 <IN> CPC) <OR> (216/6 <IN> CPC) <OR> (216/7 <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.
