Hierarchy/Derived subclasses
| 313 / 162 | -> 163 | -> 164 | |
| -> 165 | -> 166 |
CIPO searches
search just 313/163- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/163 <IN> CPC) <OR> (313/164 <IN> CPC) <OR> (313/165 <IN> CPC) <OR> (313/166 <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.
