Longhorn HD LLC has filed a second wave in the litigation campaign that it began last May, suing Advantech (2:19-cv-00061), Inventec (2:19-cv-00063), Pegatron (ASRock) (2:19-cv-00062), Quanta Computer (2:19-cv-00064), and Wistron (Wiwynn) (2:19-cv-00065) in the Eastern District of Texas. The NPE asserts four of the seven patents already at issue in the campaign, targeting the defendants’ provision of hard disk drives with SMART (Self-Monitoring Analysis and Report Technology) functionality, rack-mounted computers, and “hot-swappable” ATA hard disk drives “configured with Redundant Array of Multiple Disks (‘RAID’)”. Longhorn HD acquired the patents, themselves of disparate origins, in March 2018 from Intellectual Ventures LLC (IV).
Longhorn HD LLC, a Texas entity created in mid-January, has launched a new litigation campaign, suing Acer (2:18-cv-00221), ASUS (2:18-cv-00222), Fujitsu (2:18-cv-00223), Giga-Byte Technology (2:18-cv-00224), Hitachi (2:18-cv-00225), and MiTAC (2:18-cv-00226). Seven patents, developed at disparate sources but all apparently received from Intellectual Ventures LLC (IV), have been asserted across Longhorn HD’s complaints. Each of those pleadings targets servers and server enclosures with three of the patents: two generally related to connecting rack-mounted computers and the third to “hot-swappable” ATA hard disk drives. Acer, ASUS, and Fujitsu are further accused of infringing the other four patents, two of them through the provision of desktop computers that incorporate hard disk drives manufactured by either Hitachi or Western Digital and the other two through the manufacture and sale of certain laptop computers.
