Charity Break the Cycle has filed a US$10m lawsuit against sports giant adidas for alleged misuse of its name and logo.

Break the Cycle, which aims to stamp out domestic violence, is accusing adidas of using its name on more than 40 items in rapper Missy Elliott's 'Respect ME' line, without formal authorisation.

The charity, which filed the lawsuit in federal court in Manhattan, said its spokesperson Elliott launched the range in 2004 with an agreement that a proportion of profits would go to Break the Cycle.

However, the two parties never reached a proper licensing agreement, it says, and adidas reportedly continued to use the logo up until February this year, advancing Break the Cycle about $50,000 but failing to explain how it calculated the amount.

just-style contacted adidas' head of global PR, Jan Runau, who said: "adidas has a partnership with artist and producer Missy Elliott for her Respect ME clothing, footwear and accessories line.  adidas and Missy have previously made financial and product donations to Break the Cycle in support of educating and empowering youth to end the cycle of domestic violence. 

"adidas, along with Missy, is saddened that Break the Cycle has chosen to file a meritless lawsuit after receiving such support from adidas and Missy. We will continue to support the education and empowerment of youth to end the cycle of domestic violence."
