Description: 70 / (12) Special Application (13) For Plural Different Mechanisms
Hierarchy/Derived subclasses
CIPO searches
search just 70/13- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((70/13 <IN> CPC) <OR> (70/14 <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.
