CIPO searches
search just 312/73- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((312/73 <IN> CPC) <OR> (312/73.5 <IN> CPC) <OR> (312/74 <IN> CPC) <OR> (312/75 <IN> CPC) <OR> (312/76 <IN> CPC) <OR> (312/77 <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.
