So far this year, Uniloc Luxembourg S.A. and Uniloc USA, Inc. (collectively, Uniloc) have kicked off two of their seven new litigation campaigns by filing suit against Amazon, asserting patents recently acquired from Pendrell Corporation. Uniloc, however, has also added cases against Amazon to a couple of the many litigation campaigns that it began last year. The latest (2:18-cv-00123) is a case over a patent received from HP Enterprise, generally related to using a “palm-sized computer” to control a “service” on a network. Uniloc accuses Amazon of infringement through provision of its Alexa platform that allows, for example, certain smartphones and tablets to control other devices, including “Echo Dot, Echo Show, Echo, Tap, and video cameras”.
