CIPO searches
search just 313/162- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/162 <IN> CPC) <OR> (313/163 <IN> CPC) <OR> (313/164 <IN> CPC) <OR> (313/165 <IN> CPC) <OR> (313/166 <IN> CPC) <OR> (313/167 <IN> CPC) <OR> (313/168 <IN> CPC) <OR> (313/169 <IN> CPC) <OR> (313/170 <IN> CPC) <OR> (313/170.5 <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.
