ADT, the largest home-security company in the U.S., filed a lawsuit accusing Amazon’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 federal judge in Florida to order Ring to cease using what it says are look-alike signs, and pay unspecified cash compensation.
Amazon had worked with ADT in the past but the Boca Raton-based company is now partnered with Alphabet Inc.’s Google. Google bought a $450 million stake in ADT last year to get its Nest smart-home products in front of new customers.
The companies are vying for a greater share of the growing market for connected-home security. ADT is the leader of the $18 billion U.S. residential monitoring market, though its dominance is being challenged by new entrants, according to Bloomberg Intelligence analyst Eshan Toorabally. One in five U.S. single-family homes are professionally monitored.
