CIPO searches
search just 129/35- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((129/35 <IN> CPC) <OR> (129/36 <IN> CPC) <OR> (129/37 <IN> CPC) <OR> (129/38 <IN> CPC) <OR> (129/39 <IN> CPC) <OR> (129/40 <IN> CPC) <OR> (129/41 <IN> CPC) <OR> (129/42 <IN> CPC) <OR> (129/43 <IN> CPC) <OR> (129/44 <IN> CPC) <OR> (129/45 <IN> CPC) <OR> (129/46 <IN> CPC) <OR> (129/47 <IN> CPC) <OR> (129/48 <IN> CPC) <OR> (129/49 <IN> CPC) <OR> (129/50 <IN> CPC) <OR> (129/51 <IN> CPC) <OR> (129/52 <IN> CPC) <OR> (129/53 <IN> CPC) <OR> (129/54 <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.
