Hierarchy/Derived subclasses
| 107 / 15 | -> 16 | -> 17 |
CIPO searches
search just 107/16- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((107/16 <IN> CPC) <OR> (107/17 <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.
