CIPO searches
search just 253/65- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((253/65 <IN> CPC) <OR> (253/66 <IN> CPC) <OR> (253/67 <IN> CPC) <OR> (253/68 <IN> CPC) <OR> (253/69 <IN> CPC) <OR> (253/70 <IN> CPC) <OR> (253/71 <IN> CPC) <OR> (253/72 <IN> CPC) <OR> (253/73 <IN> CPC) <OR> (253/74 <IN> CPC) <OR> (253/75 <IN> CPC) <OR> (253/76 <IN> CPC) <OR> (253/77 <IN> CPC) <OR> (253/78 <IN> CPC) <OR> (253/79 <IN> CPC) <OR> (253/80 <IN> CPC) <OR> (253/81 <IN> CPC) <OR> (253/82 <IN> CPC) <OR> (253/83 <IN> CPC) <OR> (253/84 <IN> CPC) <OR> (253/85 <IN> CPC) <OR> (253/7.4 <IN> CPC) <OR> (253/7.5 <IN> CPC) <OR> (253/7.6 <IN> CPC) <OR> (253/7.7 <IN> CPC) <OR> (253/7.8 <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.
