CIPO searches
search just 312/65- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((312/65 <IN> CPC) <OR> (312/66 <IN> CPC) <OR> (312/67 <IN> CPC) <OR> (312/68 <IN> CPC) <OR> (312/68.1 <IN> CPC) <OR> (312/69 <IN> CPC) <OR> (312/70 <IN> CPC) <OR> (312/71 <IN> CPC) <OR> (312/72 <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.
