Hierarchy/Derived subclasses
| 25 / 98 | -> 103 | -> 109 | -> 112 | -> 113 |
| -> 114 |
CIPO searches
search just 25/112- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((25/112 <IN> CPC) <OR> (25/113 <IN> CPC) <OR> (25/114 <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.
