L’Oréal has filed a lawsuit against popular clean skin care brand Drunk Elephant, accusing the latter of patent infringement, according to a report published by the World Intellectual Property Review.
Drunk Elephant is charged with violating the French beauty giant’s patent for stabilised ascorbic acid compositions with its C-Firma Day Serum. What’s more, the Tiffany Masterson-owned brand has continued to sell the product, despite being made aware of the infringement more than a year ago.
“The C-Firma products can only be used in a manner that infringes the ‘841 patent, and on information and belief have been used by Drunk Elephant’s customers in a manner that directly infringes one of more claims of the ‘841 patent,” the writ reads, per the World Intellectual Property Review.
