Hierarchy/Derived subclasses
| 312 / 12 | -> 13 | -> 14 |
CIPO searches
search just 312/13- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((312/13 <IN> CPC) <OR> (312/14 <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.
