CIPO searches
search just 313/89- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/89 <IN> CPC) <OR> (313/90 <IN> CPC) <OR> (313/91 <IN> CPC) <OR> (313/92 <IN> CPC) <OR> (313/93 <IN> CPC) <OR> (313/94 <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.
