Description: 84 / (2) String Instruments (33) Plucked
Hierarchy/Derived subclasses
CIPO searches
search just 84/33- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((84/33 <IN> CPC) <OR> (84/34 <IN> CPC) <OR> (84/35 <IN> CPC) <OR> (84/36 <IN> CPC) <OR> (84/37 <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.
