The latter group is accused of infringing a single patent over communications platforms that support features for activating hold music for callers, although the cases against AT&T, Ericsson, and Verizon have already been dismissed (without prejudice). Bose, Vizio, and Yamaha, meanwhile, are accused of infringing a separate patent over devices (soundbars, TVs, and AV receivers, respectively) that support volume adjustment via voice commands issued to a virtual assistant (Amazon Alexa for Bose, Google Assistant for Yamaha, and both for Vizio).
