CIPO searches
search just 154/93- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/93 <IN> CPC) <OR> (154/94 <IN> CPC) <OR> (154/95 <IN> CPC) <OR> (154/96 <IN> CPC) <OR> (154/97 <IN> CPC) <OR> (154/98 <IN> CPC) <OR> (154/99 <IN> CPC) <OR> (154/100 <IN> CPC) <OR> (154/101 <IN> CPC) <OR> (154/102 <IN> CPC) <OR> (154/103 <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.
