Nestle has insisted that it will "vigorously" resist claims from Weight Watchers International that the Swiss food giant has infringed trademark rights.

Weight Watchers filed a lawsuit in the US yesterday (17 September), alleging that Nestle illegally used its name and 'points' system to promote its Skinny Cow low-fat ice cream and  Stouffer's Lean Cuisine frozen meals.

The US-based weight management company said that it is seeking a restitution of "improper" profits, triple damages and punitive damages. The group is also seeking to prevent Nestle from further using its trademarks.

However, a spokesperson for Nestle insisted this afternoon that the claims were baseless.

"We are aware that this case has been filed in the United States and we are reviewing the allegations. We are confident that the lawsuit is without merit and will vigorously defend ourselves against these allegations," the spokesperson told just-food.
