CIPO searches
search just 313/35.3- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/35.3 <IN> CPC) <OR> (313/35.31 <IN> CPC) <OR> (313/35.311 <IN> CPC) <OR> (313/35.312 <IN> CPC) <OR> (313/35.313 <IN> CPC) <OR> (313/35.315 <IN> CPC) <OR> (313/35.316 <IN> CPC) <OR> (313/35.317 <IN> CPC) <OR> (313/35.318 <IN> CPC) <OR> (313/35.319 <IN> CPC) <OR> (313/35.3191 <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.
