CIPO searches
search just 313/1.6- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/1.6 <IN> CPC) <OR> (313/1.7 <IN> CPC) <OR> (313/1.8 <IN> CPC) <OR> (313/1.9 <IN> CPC) <OR> (313/1.91 <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.
