CIPO searches
search just 313/142- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/142 <IN> CPC) <OR> (313/143 <IN> CPC) <OR> (313/144 <IN> CPC) <OR> (313/145 <IN> CPC) <OR> (313/146 <IN> CPC) <OR> (313/147 <IN> CPC) <OR> (313/148 <IN> CPC) <OR> (313/149 <IN> CPC) <OR> (313/150 <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.
