New Balance filed a lawsuit against designer Karl Lagerfeld for allegedly too closely copying its logo.

The lawsuit, first reported by TMZ, claims Lagerfeld used a capital “K” on a pair of sneakers under the Karl Lagerfeld brand that closely resembles New Balance's iconic “N” logo. “This creates confusion” between the two labels.

“On June 3, 2014, New Balance filed a lawsuit against Karl Lagerfeld to protect our intellectual property rights related to our iconic Lifestyle footwear designs. Although we cannot comment on the specifics of the case, we believe it is vital to actively and vigorously defend our brand,” a New Balance spokesperson tells Pret-a-Reporter.
