Hierarchy/Derived subclasses
| 145 / 24 | -> 25 |
CIPO searches
search just 145/24- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((145/24 <IN> CPC) <OR> (145/25 <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.
