Hierarchy/Derived subclasses
| 313 / 35 | -> 35.34 | -> 35.3405 |
| -> 35.341 |
CIPO searches
search just 313/35.34- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/35.34 <IN> CPC) <OR> (313/35.3405 <IN> CPC) <OR> (313/35.341 <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.
