CIPO searches
search just 182/149- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((182/149 <IN> CPC) <OR> (182/150 <IN> CPC) <OR> (182/151 <IN> CPC) <OR> (182/152 <IN> CPC) <OR> (182/153 <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.
