CIPO searches
search just 129/56- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((129/56 <IN> CPC) <OR> (129/56.1 <IN> CPC) <OR> (129/56.15 <IN> CPC) <OR> (129/56.2 <IN> CPC) <OR> (129/56.4 <IN> CPC) <OR> (129/56.6 <IN> CPC) <OR> (129/56.8 <IN> CPC) <OR> (129/57 <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.
