CIPO searches
search just 253/110- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((253/110 <IN> CPC) <OR> (253/111 <IN> CPC) <OR> (253/112 <IN> CPC) <OR> (253/113 <IN> CPC) <OR> (253/114 <IN> CPC) <OR> (253/115 <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.
