search just 32/13- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((32/13 <IN> CPC) <OR> (32/14 <IN> CPC) <OR> (32/15 <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.
