Hierarchy/Derived subclasses
| 345 / 5 | -> 6 |
| -> 7 | |
| -> 8 | |
| -> 9 |
CIPO searches
search just 345/5- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((345/5 <IN> CPC) <OR> (345/6 <IN> CPC) <OR> (345/7 <IN> CPC) <OR> (345/8 <IN> CPC) <OR> (345/9 <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.
