Hierarchy/Derived subclasses
70 / 12 | -> 25 | -> 35 | -> 46 | -> 47 |
CIPO searches
search just 70/46- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((70/46 <IN> CPC) <OR> (70/47 <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.
