CIPO searches
search just 313/119- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/119 <IN> CPC) <OR> (313/120 <IN> CPC) <OR> (313/121 <IN> CPC) <OR> (313/122 <IN> CPC) <OR> (313/123 <IN> CPC) <OR> (313/124 <IN> CPC) <OR> (313/125 <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.
