| 92 / 62 | -> 63 |
| -> 64 | |

| -> 66 |
CIPO searches
search just 92/62- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((92/62 <IN> CPC) <OR> (92/63 <IN> CPC) <OR> (92/64 <IN> CPC) <OR> (92/65 <IN> CPC) <OR> (92/66 <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.
