Hierarchy/Derived subclasses
183 / 72 | -> 109 | -> 110 |
CIPO searches
search just 183/109- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((183/109 <IN> CPC) <OR> (183/110 <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.
