Hierarchy/Derived subclasses
165 / 1 | -> 34 | -> 36 | -> 37 |
CIPO searches
search just 165/36- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((165/36 <IN> CPC) <OR> (165/37 <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.
