ADT is suing Ring, the security company said Tuesday, alleging the Amazon-owned video doorbell company infringed on its trademarks when it adopted "a blue octagon mark that is virtually indistinguishable from ADT's iconic blue octagon mark."
"Ring's use of ADT's Famous Blue Octagon will mislead consumers to believe that Ring is endorsed by and/or partnering with ADT, or will cause consumers to believe that Ring's products are genuine ADT products when, in fact, they are not," ADT said in the complaint.
It also alleged that in 2017, Ring "misappropriated an unauthorized copy of the source code and documentation for a new home security and automation platform that ADT was developing," according to the complaint. Amazon had not yet purchased Ring at the time.
ADT also sued for unfair competition. The complaint said that ADT had offered Ring to customers since the prior year, 2016, but the doorbell company used ADT's software to "significantly shorten the time and cost for bringing its own competing security system to market."
