Under Armour, Baltimore, will pursue business and legal courses of action to stop a Chinese company, Uncle Martian, from using a logo that is similar to the United States company’s trademarked logo.

The litigation comes as numerous media outlets reported that Uncle Martian’s logo, revealed at a launch gala last week, resembled Under Armour’s logo.

“Under Armour is aware of the Uncle Martian launch event,” Under Armour said in an email sent to several media outlets. “Uncle Martian’s uses of Under Armour’s famous logo, name, and other intellectual property are a serious concern and blatant infringement. Under Armour will vigorously pursue all business and legal courses of action.”

Under Armour celebrated $4 billion in annual sales in 2015, according to Fortune, and the name and logo are registered in the U.S., China, the European Union and several other international markets.

This is not the first time that an apparent trademark rip-off has cropped up in China. adidas, Blackberry, Oreo and Sony are only some of the companies that have seen apparent knockoffs to their respective brands rise in China.
