Cantarella is a naming case for founders who like elegant words, foreign words or words that hint at quality. The fight was not simply about what the words meant in Italian. The Court asked how the words would be understood by ordinary Australian consumers of the goods.
The business lesson is that trade mark clearance is not a dictionary exercise. A word can be descriptive to some people and still distinctive in the relevant Australian market, but that depends on evidence, the goods and how traders in the market are likely to use the word.
