Hierarchy/Derived subclasses
| 129 / 35 | -> 39 | -> 43 | -> 44 |
| -> 45 |
CIPO searches
search just 129/43- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((129/43 <IN> CPC) <OR> (129/44 <IN> CPC) <OR> (129/45 <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.
