Amazon (2:21-cv-00435) has joined Apple, Alphabet (Google), and Samsung as a defendant in the growing litigation campaign of Jawbone Innovations, LLC. Targeted is Amazon’s provision of products with voice activity detection features and related microphone arrays, including smart home devices, smart speakers, smart displays, hands-free streaming devices, and ear buds. The complaint, filed in the Eastern District of Texas on November 29, asserts eight former Aliph (d/b/a Jawbone) patents out of the nearly 80 active grants apparently held by the NPE plaintiff.
