Hierarchy/Derived subclasses
| 154 / 41 | -> 93 | -> 95 | -> 96 |
| -> 97 |
CIPO searches
search just 154/95- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/95 <IN> CPC) <OR> (154/96 <IN> CPC) <OR> (154/97 <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.
