In July, Longhorn HD LLC expanded two of its three litigation campaigns, adding suits against Elitegroup Computer Systems (2:21-cv-00278), Onex (Celestica) (2:21-cv-00280), and Pegatron (2:21-cv-00279) to its earliest litigation campaign, as well as a single suit against Kyocera (2:21-cv-00277) to its latest litigation campaign. The plaintiff asserts seven patents—one against Kyocera and six in overlapping sets against the remaining defendants—each acquired from Intellectual Ventures LLC (IV) in several March 2018 assignments. Kyocera is alleged to infringe through the provision of smartphones that support Google’s device backup systems, while Celestica, Elitegroup, and Pegatron are accused over various devices (e.g., 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)).
