Seven Patents, Received from IV but Originating from Disparate Sources, Asserted in New Computer Hardware Campaign
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.
