Hierarchy/Derived subclasses
| 92 / 7 | -> 26 | -> 31 | -> 32 |
| -> 33 |
CIPO searches
search just 92/31- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((92/31 <IN> CPC) <OR> (92/32 <IN> CPC) <OR> (92/33 <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.
