Longhorn HD LLC has sued Atos (2:21-cv-00115), Best Buy (2:21-cv-00122), Broadcom (LSI) (2:21-cv-00114), Microchip (2:21-cv-00112), and Oracle (2:21-cv-00116), all in the Eastern District of Texas. The NPE asserts in overlapping sets seven patents that it received from Intellectual Ventures LLC (IV) in a March 2018 assignment. The NPE’s infringement allegations target the provision of various computing devices (e.g., computers, laptops, sensors, servers, storage devices, etc.), including those that incorporate hard disk drives (HDDs) manufactured by Western Digital (and/or its subsidiary Hitachi Global Storage Technologies (HGST)). At issue are features related to damage protection, hard drive monitoring, mechanical actuators, and server mounting hardware.
Longhorn HD LLC has launched a third litigation campaign, suing Samsung (2:20-cv-00350) in the Eastern District of Texas over a single patent, acquired from Intellectual Ventures LLC (IV) and generally related to an “information backup system”. The NPE targets Samsung over the provision of smartphones that support Smart Switch, a technology for “seamlessly” upgrading from one model to another. Concurrently, Longhorn HD has added three new defendants to its existing network security campaign, hitting Mitel Networks (Mitel SoftwareTechnologies) (2:20-cv-00350), NetScout Systems (2:20-cv-00349),and Trend Micro (2:20-cv-00348), also in East Texas, over a variety of networking hardware and software products.
Earlier this year, Longhorn HD LLC added Eastern District of Texas cases against Compal Electronics, Hon Hai, Inspur Group, and Micro-Star to its computer hardware campaign, this past week also suing NEC (2:20-cv-00148) and Panasonic (2:20-cv-00150) in the same district. The NPE alleges infringement, of overlapping subsets of patents acquired from Intellectual Ventures LLC (IV), through the provision of various computing devices, targeting features related to hard drive monitoring, mechanical actuators, and damage protection as well as server mounting hardware.
