CIPO searches
search just 313/183- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((313/183 <IN> CPC) <OR> (313/184 <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.
