CIPO searches
search just 313/4- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/4 <IN> CPC) <OR> (313/5 <IN> CPC) <OR> (313/6 <IN> CPC) <OR> (313/7 <IN> CPC) <OR> (313/8 <IN> CPC) <OR> (313/9 <IN> CPC) <OR> (313/10 <IN> CPC) <OR> (313/11 <IN> CPC) <OR> (313/12 <IN> CPC) <OR> (313/13 <IN> CPC) <OR> (313/14 <IN> CPC) <OR> (313/15 <IN> CPC) <OR> (313/16 <IN> CPC) <OR> (313/17 <IN> CPC) <OR> (313/18 <IN> CPC) <OR> (313/19 <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.
