ADT sues Amazon’s Ring over ‘brazen’ copies of blue octagon sign

In a 2016 agreement, Ring pledged that it wouldn’t use any trademarks that would be confusingly similar to ADT and yet began using a lighted yard sign in a blue octagon, according to the complaint. — Amazon

ADT Inc, the largest home-security company in the US, has filed a lawsuit accusing Amazon.com Inc’s Ring service of copying its trademarked blue octagon symbol “to tout a reputation for trust to potential customers that it has not earned”.

ADT said it’s been using the blue octagon in lawn signs and window stickers for decades, and that they are displayed by some 6.5 million customers as a sort of “keep out” warning to burglars. The company wants a US federal judge in Florida to order Ring to cease using what it says are look-alike signs, and pay unspecified cash compensation.
