Hierarchy/Derived subclasses
| 92 / 7 | -> 10 | -> 13 | -> 13.1 |
| -> 13.2 | |||
| -> 13.3 |
CIPO searches
search just 92/13- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((92/13 <IN> CPC) <OR> (92/13.1 <IN> CPC) <OR> (92/13.2 <IN> CPC) <OR> (92/13.3 <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.
