Signal Foundation Sues ADT Over ‘Signal Chat,’ Citing Trademark Infringement
The Signal Foundation (STF), the nonprofit behind the Signal encrypted messaging app, filed a complaint with the U.S. District Court against ADT for trademark infringement and unfair competition.
In the complaint, filed Sept. 23 in California, STF states that ADT’s Signal Chat, the company’s intrusion alarm text message notification service, is too similar to Signal’s own messaging app.
