Hierarchy/Derived subclasses
| 129 / 4 | -> 5 | -> 6 | -> 11 | -> 12 |
| -> 13 |
CIPO searches
search just 129/11- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((129/11 <IN> CPC) <OR> (129/12 <IN> CPC) <OR> (129/13 <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.
