Hierarchy/Derived subclasses
107 / 1 | -> 2 |
-> 3 |
CIPO searches
search just 107/1- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((107/1 <IN> CPC) <OR> (107/2 <IN> CPC) <OR> (107/3 <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.
