Currently available USPTO records indicate that most of the patents held by VoiceBox Technologies, a Washington-based company developing voice assistant and “conversational AI” technology, including significant work for automotive clients, were transferred in March 2018 to VB Assets, LLC, an entity created in Delaware on February 12, 2018. That entity has now turned plaintiff, suing Amazon (1:19-cv-01410) over six of the patents received, all generally related to various aspects of voice processing, targeting the tech giant’s provision of Alexa products. The complaint recounts an extensive history of purported contacts between VoiceBox Technologies and Amazon, beginning in 2011 and ending in April 2017.
