Kendall Jenner‘s 818 Tequila company isn’t exactly raising a glass to this news. 

Tequila 512 sued its rival for trademark infringement. 

CelebHomes News has obtained court documents that Tequila512 claims 818 Tequila “simply copied” the brand of its beverage. Attorneys point to the use of a three-digit area code in the name of Jenner’s brand (818 serves the San Fernando Valley in California while 512 is in Austin, Texas) and allege that 818 Tequila “chose to copy” the brand’s distinctive black lettering inside a vertical yellow rectangle on its bottles. Court documents stated that customers would be able to mistakenly believe the products were related if they compared the two.

According to 818 Tequila, a representative of the company stated, “We’re reviewing the complaint. We believe that the allegations are unfounded.”
