Hierarchy/Derived subclasses
| 363 / 1.5 | -> 1.8 | -> 1.81 |
| -> 1.9 |
CIPO searches
search just 363/1.5- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((363/1.5 <IN> CPC) <OR> (363/1.8 <IN> CPC) <OR> (363/1.81 <IN> CPC) <OR> (363/1.9 <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.
