`
`FACTUAL BACKGROUND
`
`A.
`
`THE ASSERTED PATENT
`
`9. The '457 Patent, entitled "Appliance Immersion Cooling System", was duly and legally
`
`issued on September 3, 2019 by the U.S. Patent and Trademark Office, and names Christopher L.
`
`Boyd of Austin, TX (US), James P. Koen of Round Rock, TX (US), David Christopher of
`
`Laguna, Austin, TX (US), Thomas R. Turner of Georgetown, TX (US), Kenneth D. Swinden of
`
`Hutto, TX (US), Mario Conti Garcia of Austin, TX (US), and John Charles Tribou of Austin, TX
`
`(US) as the inventors. The application leading to the '457 Patent was filed on April 30, 2014. A
`
`true and correct copy of the '457 Patent is attached hereto as Exhibit A and incorporated herein
`
`by reference.
`
`10. The '457 Patent claims, according to at least one embodiment, among other things, an
`
`appliance immersion cooling system that includes a tank adapted to immerse in a dielectric fluid
`
`a plurality of electrical appliances, each in a respective appliance slot distributed vertically along,
`
`and extending transverse to, a long wall of the tank. The tank includes a weir, integrated
`
`horizontally into the long wall of the tank adjacent all appliance slots, having an overflow lip
`
`adapted to facilitate substantially uniform recovery of the dielectric fluid flowing through each
`
`appliance slot, and a dielectric fluid recovery reservoir positioned vertically beneath the overflow
`
`lip of the weir and adapted to receive the dielectric fluid as it flows over the weir. The appliance
`
`immersion cooling system also includes a primary circulation facility adapted to circulate the
`
`dielectric fluid through the tank. The primary circulation facility includes a plenum, positioned
`
`adjacent the bottom of the tank, adapted to dispense the dielectric fluid substantially uniformly
`
`upwardly through each appliance slot. The appliance cooling system also includes a secondary
`
`fluid circulation facility adapted to extract heat from the dielectric fluid circulating in the primary

`
`circulation facility, and to dissipate to the environment the heat so extracted, and a control
`
`facility adapted to coordinate the operation of the primary and secondary fluid circulation
`
`facilities as a function of the temperature of the dielectric fluid in the tank.
`
`11. The '457 Patent also claims, according to at least one embodiment, among other things, a
`
`tank module adapted for use in an appliance immersion cooling system. The tank module
`
`includes a tank adapted to immerse in a dielectric fluid a plurality of electrical appliances, each
`
`in a respective appliance slot distributed vertically along, and extending transverse to, a long wall
`
`of the tank. The tank includes a weir, integrated horizontally into the long wall of the tank
`
`adjacent all appliance slots, having an overflow lip adapted to facilitate substantially uniform
`
`recovery of the dielectric fluid flowing through each appliance slot, and a dielectric fluid
`
`recovery reservoir positioned vertically beneath the overflow lip of the weir and adapted to
`
`receive the dielectric fluid as it flows over the weir. The tank module also includes a primary
`
`circulation facility adapted to circulate the dielectric fluid through the tank, including a plenum,
`
`positioned adjacent the bottom of the tank, adapted to dispense the dielectric fluid substantially
`
`uniformly upwardly through each appliance slot, and a control facility adapted to control the
`
`operation of the primary fluid circulation facility as a function of the temperature of the dielectric
`
`fluid in the tank.
`
`12. The '457 Patent also claims, according to at least one embodiment, among other things, a
`
`tank module adapted for use in an appliance immersion cooling system. The tank module
`
`includes a tank adapted to immerse in a dielectric fluid a plurality of electrical appliances, each
`
`in a respective appliance slot distributed vertically along, and extending transverse to, a long wall
`
`of the tank. The tank includes a weir, integrated horizontally into the long wall of the tank
`
`adjacent all appliance slots, adapted to facilitate substantially uniform recovery of the dielectric

`
`fluid flowing through each appliance slot. The tank module also includes a primary circulation
`
`facility adapted to circulate the dielectric fluid through the tank, including a plenum, positioned
`
`adjacent the bottom of the tank, adapted to dispense the dielectric fluid substantially uniformly
`

`
`16. MGT incorporates the allegations of the above paragraphs herein by reference, the same
`
`as if set forth herein.
`
`17. The '457 Patent was filed April 30, 2014, and legally issued by the United States Patent
`
`and Trademark Office ("USPTO") on September 3, 2019. The '457 Patent is presumed valid and
`
`enforceable pursuant to 35 U.S.C. § 282.
`
`18. Without a license or permission from MGT, Immersion has infringed and/or continue to
`
`infringe one or more claims of the '457 Patent – directly, contributorily, and/or by inducement –
`
`by importing, making, using, offering for sale, or selling products and devices that embody the

`
`violation of 35 U.S.C. § 271.
`
`A.

`
`19. On information and belief, Immersion has directly infringed claims of the '457 Patent in
`
`the Northern District of Texas, the State of Texas, and elsewhere in the United States, by at least
`
`making, using, selling, and offering for sale an apparatus for an appliance immersion cooling
`
`system that satisfies each and every limitation of at least claims 1, 6, and 11 of the '457 Patent,

`
`22. Attached hereto as Exhibit D is an exemplary claim chart detailing representative
`
`infringement of claim 11 of the '457 Patent by Immersion.
`
`B.
`
`INDUCED INFRINGEMENT
`
`23. On information and belief, Immersion has been and is inducing infringement of MGT's
`
`'457 Patent by actively and knowingly inducing others to make, use, sell, offer for sale, or import
`
`at least the Accused Product that embody or use the invention claimed in the '457 Patent in
`
`violation of 35 U.S.C. § 271(b).
`
`24. Immersion induced infringement by publication of documents for using at least the
`
`Accused Product in an infringing manner, as well as advertising infringing uses to the '457
`
`Patent. Immersion's customers' subsequent usage of the Accused Products to cool electronic
`
`appliances via immersion placed every element of at least claim 1, 6, and 11 of the '457 Patent
`
`into service, constituting control and therefore infringement.
`
`25. Defendant's infringement has been, and continues to be knowing, intentional, and willful,
`
`at least beginning 07 February 2020 with the delivery of MGT's first notice letter and
`
`accompanying claim chart.
`
`26. Immersion's acts of infringement of the '457 Patent have caused and will continue to
`
`cause MGT damages for which MGT is entitled to compensation pursuant to 35 U.S.C. § 284.
`
`27. Immersion's acts of infringement of the ‘457 Patent have caused and will continue to
`
`cause MGT immediate and irreparable harm unless such infringing activities are enjoined by this
`
`Court pursuant to 35 U.S.C. § 283. MGT has no adequate remedy at law.
`
`28. This case is exceptional and, therefore, MGT is entitled to an award of attorney fees
`
`pursuant to 35 U.S.C. § 285.

`formly upwardly through each appliance slot . A weir , inte
`grated horizontally into a long wall of the tank , is adapted to
`facilitate substantially uniform recovery of the dielectric
`fluid flowing through each appliance slot . All active and
`most passive components of both the primary and secondary
`fluid circulation facilities , and the control facility are fully
`redundant , and are adapted automatically to operate in a
`fail - soft mode .

`APPLIANCE IMMERSION COOLING
`SYSTEM
`
`is an essential element in the system architecture , such as the
`central processing unit ( “ CPU ” ) . One possible solution to
`this problem is to immerse circuit assemblies vertically into

`a tank containing the cooling fluid such that each of the
`5 various assemblies can be withdrawn independently from
`APPLICATIONS
