Hierarchy/Derived subclasses
302 / 15 | -> 16 | -> 17 |
-> 18 |
CIPO searches
search just 302/15- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((302/15 <IN> CPC) <OR> (302/16 <IN> CPC) <OR> (302/17 <IN> CPC) <OR> (302/18 <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.
