Hierarchy/Derived subclasses
| 25 / 98 | -> 100 | -> 101 |
CIPO searches
search just 25/100- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((25/100 <IN> CPC) <OR> (25/101 <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.
