Hierarchy/Derived subclasses
| 345 / 29 | -> 30 | -> 46 | -> 47 | -> 48 |
CIPO searches
search just 345/47- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((345/47 <IN> CPC) <OR> (345/48 <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.
