Hierarchy/Derived subclasses
| 107 / 33 | -> 34 | -> 35 |
CIPO searches
search just 107/34- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((107/34 <IN> CPC) <OR> (107/35 <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.
