Hierarchy/Derived subclasses
| 165 / 1 | -> 43 | -> 48 | -> 49 |
CIPO searches
search just 165/48- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((165/48 <IN> CPC) <OR> (165/49 <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.
