Hierarchy/Derived subclasses
| 361 / 1 | -> 2 | -> 8 | -> 9 | -> 10 |
CIPO searches
search just 361/8- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((361/8 <IN> CPC) <OR> (361/9 <IN> CPC) <OR> (361/10 <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.
