Amazon (1:23-cv-00581) is the latest defendant to be added to the litigation campaign that Dialect, LLC launched in February 2023 with a suit against Samsung, which Dialect followed with a case against Alphabet (Google) just two months later. In the new Eastern District of Virginia complaint, the plaintiff asserts seven former Voicebox Technologies patents broadly directed to processing and responding to “natural language” inputs. The defendant is targeted over the provision of the Alexa virtual assistant and a wide variety of products that support it, ranging from Amazon’s e-commerce website to the AmazonBasics Microwave. At issue are features related to speech recognition and natural language processing.
