Hierarchy/Derived subclasses
| 129 / 35 | -> 47 | -> 48 |
| -> 49 | ||
| -> 50 |
CIPO searches
search just 129/47- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((129/47 <IN> CPC) <OR> (129/48 <IN> CPC) <OR> (129/49 <IN> CPC) <OR> (129/50 <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.
