Voice Control Vehicles, LLC (VCV), a subsidiary of Strategic Intellectual Solutions, LLC (SIS), has filed a fresh wave of cases in its sole litigation campaign, suing Esprit Model (6:19-cv-01816) in the Middle District of Florida and Best Choice Products (8:19-cv-01807), Contixo (8:19-cv-01808), and Yuneec (8:19-cv-01809) in the Central District of California. VCV asserts a single patent, generally related to a control system for a flying device, with infringement allegations focusing on radio transmitters (as to Esprit Model) and/or drones, used in combination with apps and a mobile device (as to the others). Prior cases in the campaign, begun in September 2018 with a suit against Alpha Group and subsequently hitting AWW Industries and DGL Group, World Trading 23, and MukkiM, have been dismissed within months of filing.
