Hierarchy/Derived subclasses
| 312 / 39 | -> 45 | -> 46 |
CIPO searches
search just 312/45- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((312/45 <IN> CPC) <OR> (312/46 <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.
