Hierarchy/Derived subclasses
| 92 / 7 | -> 26 | -> 27 | -> 27.1 | -> 27.2 | -> 27.3 |
| -> 27.4 |
CIPO searches
search just 92/27.1- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((92/27.1 <IN> CPC) <OR> (92/27.2 <IN> CPC) <OR> (92/27.3 <IN> CPC) <OR> (92/27.4 <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.
