Questão jurídica principal
Whether Nestlé's use of the slogan 'c'est bon la vie!' was unfair competition
Decisão extraída
The slogan's use was not shown to create a concrete risk of confusion or otherwise violate the rules of good faith on the facts found, so the claim failed except as to the trademark-deposit conduct.
Fundamentação extraída
The slogan was a common expression in the public domain; the record did not show distinctiveness acquired through use or concrete confusion between biscuits and yoghurts. Mere registration did not by itself establish a confusing market impact.
