CIPO searches
search just 313/152- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/152 <IN> CPC) <OR> (313/153 <IN> CPC) <OR> (313/154 <IN> CPC) <OR> (313/155 <IN> CPC) <OR> (313/156 <IN> CPC) <OR> (313/157 <IN> CPC) <OR> (313/158 <IN> CPC) <OR> (313/159 <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.
