| -> 15.5 | ||
| -> 15.6 |
CIPO searches
search just 182/15.3- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((182/15.3 <IN> CPC) <OR> (182/15.4 <IN> CPC) <OR> (182/15.5 <IN> CPC) <OR> (182/15.6 <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.
