CIPO searches
search just 154/92.1- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((154/92.1 <IN> CPC) <OR> (154/92.2 <IN> CPC) <OR> (154/92.3 <IN> CPC) <OR> (154/92.4 <IN> CPC) <OR> (154/92.5 <IN> CPC) <OR> (154/92.6 <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.
