Hierarchy/Derived subclasses
312 / 62 | -> 78 | -> 78.1 |
CIPO searches
search just 312/78- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((312/78 <IN> CPC) <OR> (312/78.1 <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.
