CIPO searches
search just 323/4- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((323/4 <IN> CPC) <OR> (323/5 <IN> CPC) <OR> (323/6 <IN> CPC) <OR> (323/7 <IN> CPC) <OR> (323/8 <IN> CPC) <OR> (323/9 <IN> CPC) <OR> (323/10 <IN> CPC) <OR> (323/11 <IN> CPC) <OR> (323/12 <IN> CPC) <OR> (323/13 <IN> CPC) <OR> (323/14 <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.
