| 72 / 101 | -> 102 | |
| -> 103 | -> 104 | |
| -> 105 |
CIPO searches
search just 72/101- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((72/101 <IN> CPC) <OR> (72/102 <IN> CPC) <OR> (72/103 <IN> CPC) <OR> (72/104 <IN> CPC) <OR> (72/105 <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.
