CIPO searches
search just 107/49- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((107/49 <IN> CPC) <OR> (107/50 <IN> CPC) <OR> (107/51 <IN> CPC) <OR> (107/52 <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.
