Hierarchy/Derived subclasses
| 154 / 108 | -> 109 | -> 110 | -> 111 |
| -> 112 |
CIPO searches
search just 154/109- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/109 <IN> CPC) <OR> (154/110 <IN> CPC) <OR> (154/111 <IN> CPC) <OR> (154/112 <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.
