Plaintiff PanTaurus is a Texas limited liability company located in Beaumont.

PanTaurus claims to be the owner by assignment of U.S. Patent No. 6,272,533 for a Secure Computer System and Method of Providing Secure Access to a Computer System Including a Stand Alone Switch Operable to Inhibit Data Corruption on a Storage Device.

According to the complaints, the ‘533 Patent is a prominent, pioneering patent in the field of computer security. It has been forward-cited in more than 130 subsequently-issued U.S. patents to date, including patents originally assigned to such prominent companies as Intel (93 times), Dot Hill Systems (12 times), IBM, Nikon, Dell, Seagate, Lenovo, McAfee, Hewlett Packard, Lockheed Martin and STMicroelectronics.

Defendants are allegedly infringing the ‘533 Patent by making, having or using a secure computer system including digital computer systems comprising one or more Hadoop-compatible file systems.  A Hadoop distributed file system, or HDFS, is a distributed file system that includes computer hardware (e.g. servers and memory) and computer software for performing program functions.

Defendants also allegedly operate the components of the accused instrumentalities, including buses, processors, a data storage device and a switch.

PanTaurus is seeking an injunction against defendants, compensatory damages, interest, costs, attorneys’ fees and other relief to which it may be entitled. A jury trial is requested.
