Hierarchy/Derived subclasses
| 107 / 55 | -> 61 | -> 62 |
CIPO searches
search just 107/61- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((107/61 <IN> CPC) <OR> (107/62 <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.
