| 183 / 111 | -> 112 | -> 113 |
CIPO searches
search just 183/112- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((183/112 <IN> CPC) <OR> (183/113 <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.
