CIPO searches
search just 313/140- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/140 <IN> CPC) <OR> (313/141 <IN> CPC) <OR> (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) <OR> (313/151 <IN> CPC) <OR> (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) <OR> (313/160 <IN> CPC) <OR> (313/161 <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.
