Hierarchy/Derived subclasses
| 107 / 30 | -> 31 |
| -> 32 |
CIPO searches
search just 107/30- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((107/30 <IN> CPC) <OR> (107/31 <IN> CPC) <OR> (107/32 <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.
