Hierarchy/Derived subclasses
| 107 / 15 | -> 25 | -> 26 | |
| -> 27 | -> 28 |
CIPO searches
search just 107/25- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((107/25 <IN> CPC) <OR> (107/26 <IN> CPC) <OR> (107/27 <IN> CPC) <OR> (107/28 <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.
