Prominent plaintiffs attorney Joseph Cotchett is representing a patent holder in a case against Apple Inc. over the “Do Not Disturb” feature on the company’s mobile devices. 

Cotchett’s client in the case, San Francisco-based SMTM Technology, alleges Apple has infringed upon its “Off Mode” patent for an application blocking incoming texts, calls and notifications while driving. Inventor and Bay Area restaurateur Nick Bovis secured the patent in 2015 to help prevent distracted driving—two years before Apple rolled out its Do Not Disturb feature touting similar capabilities, according to the complaint filed Friday in the U.S. District Court for the Northern District of California.
