Hierarchy/Derived subclasses
| 112 / 12 | -> 13 | -> 16 | -> 17 |
| -> 18 |
CIPO searches
search just 112/16- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((112/16 <IN> CPC) <OR> (112/17 <IN> CPC) <OR> (112/18 <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.
