`Patent No. 8,240,362
`IPR2023-00667
`Cooler Master Co., Ltd. (“CMC” or “Petitioner”) hereby seeks inter partes
`
`Petition Requesting Inter Partes Review
`
`
`
`review of Claims 1 and 3-19 (“the Challenged Claims”) of U.S. Patent No.
`
`8,240,362. (Ex-1001 (the “’362 patent”)) of Asetek Danmark A/S (“Patent Owner.”)
`
`I.
`
`INITIAL STATEMENT
`A.
`Patent Owner Did Not Invent the “All-in-One” Cooler.
` The ’362 patent discloses a liquid cooling system used in a computer system.
`
`The use of liquid cooling to cool semiconductor chips in computer systems was
`
`generally known to a person of ordinary skill in the art (“POSITA”) long before the
`
`claimed November 7, 2003 priority date of the ’362 patent claims. (Ex-1003, 26¶.)
`
`The use of closed liquid cooling loops that utilize what is sometimes referred to in
`
`the industry as an “all-in-one” cooler (i.e., a modular pumping mechanism, what
`
`Patent Owner calls a “reservoir” in the ’362 patent, that pumps the liquid through
`
`the loop) was also generally known to a POSITA long before the claimed priority
`
`date of the ’362 patent. (Id.; see also Ex-1006-Batchelder; Ex-1007-Shin.) The ’362
`
`patent only discloses and claims a specific embodiment of such an “all-in-one”
`
`cooler. (Ex-1003, ¶26.)
`
`B. The ’362 Patent Claims Are Similar to Those This Board Has
`Already Invalidated.
`The ’362 patent is a parent of Application No. 15/626,393, which issued as
`
`U.S. Patent No. 10,078,354 (the “’354 patent”). (Ex-1001, 1:4-5; Ex-1010 (’354
`
`patent, issued from “(21) Appl. No.: 15/626,393”).) Claims 1, 4, 8, 14, 15, and 19
`
`1
`
`

`

`U.S. Patent No. 8,240,362
`IPR2023-00667
`of the ’354 patent have been found unpatentable by a Final Written Decision in
`
`Petition Requesting Inter Partes Review
`
`
`
`IPR2020-00523. (Ex-1011, 354-FWD). The IPR relating to the ’354 patent is
`
`instructive, given that the Challenged Claims here are similar to those in the ’354
`
`patent the Board has invalidated. (See id. at 30-31).
`
`II.
`
`IDENTIFICATION OF CHALLENGE UNDER 37 C.F.R. §42.104(B)
`AND RELIEF REQUESTED
`Petitioner respectfully requests that the Challenged Claims of the ’362 patent
`
`be cancelled based on the following grounds of unpatentability:

`
`III. OVERVIEW OF THE ’362 PATENT
`The ’362 patent relates to a liquid-cooling system for a central processing unit
`
`(CPU) or other processing unit of a computer system. (Ex-1001, 1:12-14; Ex-1003,
`
`¶25.) The specification purports to disclose embodiments of a small and compact
`
`liquid-cooling solution that is more efficient than existing air-cooling arrangements
`
`and
`
`that can be produced
`
`in high volume and at
`
`low cost.
`
` (Id.,
`
`2
`
`

`

`U.S. Patent No. 8,240,362
`IPR2023-00667
`1:53-56.) The ’362 patent further states (and subsequently claims) that these
`
`Petition Requesting Inter Partes Review
`
`
`
`improvements may be obtained by:
`
`a cooling system for a computer system, said computer system
`comprising: at least one unit such as a central processing unit (CPU)
`generating thermal energy and said cooling system intended for cooling
`the at least one processing unit, a reservoir having an amount of cooling
`liquid, said cooling liquid intended for accumulating and transferring
`of thermal energy dissipated from the processing unit to the cooling
`liquid, a heat exchanging interface for providing thermal contact
`between the processing unit and the cooling liquid for dissipating heat
`from the processing unit to the cooling liquid, a pump being provided
`as part of an integrate element, said integrate element comprising the
`heat exchanging interface, the reservoir and the pump, said pump
`intended for pumping the cooling liquid into the reservoir, through the
`reservoir and from the reservoir to a heat radiating means, said heat
`radiating means intended for radiating thermal energy from the cooling
`liquid, dissipated to the cooling liquid, to surroundings of the heat
`radiating means.
`(Id., 1:63-2:17; see also id. claims 1-16.)
`As shown in detail in this Petition, however, the Challenged Claims of
`
`the ’362 patent are not inventive.

`
`the Challenged Claims. (Ex-
`

`
`tube inlet connection and the tube outlet connection are connected to a heat radiator
`
`by means of connecting tubes 24 and 25 through which the cooling liquid flows into
`
`and out of the reservoir and the heat radiator, respectively. Within the heat radiator
`
`11, the cooling liquid passes a number of channels for radiating the heat, which has
`
`been dissipated into the cooling liquid inside the reservoir, and to the surroundings
`
`of the heat exchanger. The air fan 10 blows air past the channels of the heat radiator
`
`in order to cool the radiator and thereby cooling the cooling liquid flowing inside the
`

`

`

`channels through the heat radiator and back into the reservoir.” (Ex-1001,
`
`Petition Requesting Inter Partes Review
`
`
`
`13:28-41.)
`
`B.
`Priority Date
`The ’362 patent issued on April 7, 2020 from Application No. 12/826,768
`
`filed on June 30, 2010, claiming a priority date of November 7, 2003. Petitioner
`
`does not concede that the ’362 patent is entitled to a priority date of
`
`November 7, 2003, and reserves the right to challenge such claim of priority, but
`
`assumes that this date applies for purposes of this Petition. See PowerOasis, Inc. v.
`
`T-Mobile USA, Inc., 522 F.3d 1299, 1303-06 (Fed. Cir. 2008) (burden on patent
`
`owner to prove entitlement to priority date).
`
`C.
`The Challenged Claims
`Claims 1 and 3-19 are the Challenged Claims of the ’362 patent. Claims 1,
`
`14 and 17 are independent claims. Claims 3-13 depend from claim 1, claims 15 and
`
`16 depend from claim 14, and claims 18 and 19 depend from claim 17.
`
`IV. PERSON OF ORDINARY SKILL IN THE ART (“POSITA”)
`A POSITA in the field of the ’362 patent at the time of the effective filing date
`
`would have been knowledgeable regarding liquid cooling systems for computer
`
`systems, would have earned at least a bachelor’s degree, such as a B.S. (bachelor of
`
`science), or equivalent thereof, in electrical or mechanical engineering or a closely-
`
`related field, or would have possessed at least two or three years of experience in
`
`liquid cooling systems for computer systems or in similar systems. A person with
`
`5
`
`

`

`U.S. Patent No. 8,240,362
`IPR2023-00667
`less education but more relevant practical experience, depending on the nature of
`
`Petition Requesting Inter Partes Review
`
`
`
`that experience and degree of exposure to liquid cooling systems for computer
`
`systems, could also qualify as a POSITA in the field of the ’362 patent. (Ex-1003,
`
`¶¶14-19.)
`
`V. CLAIM CONSTRUCTION
`Per 37 C.F.R. § 42.100(b):
`
`“[A] claim of a patent in an IPR shall be construed using the same claim
`construction standard that would be used to construe the claim in a civil
`action under 35 U.S.C. 282(b), including construing the claim in
`accordance with the ordinary and customary meaning of such claim as
`understood by one of ordinary skill in the art and the prosecution history
`pertaining to the patent. Any prior claim construction … that is timely
`made of record in the inter partes review proceeding will be
`considered.”
`
`A.
`“reservoir”
`Petitioner and Patent Owner have stipulated to construe the term “reservoir”
`
`in the ’362 patent to mean “single receptacle defining a fluid flow path.” (Ex-1005
`
`at 2.) Petitioner submits that the claimed “reservoir” be given such construction.
`
`(Ex-1003, ¶29.)
`
`6
`
`

`

`U.S. Patent No. 8,240,362
`IPR2023-00667
`B.
`“chamber”
`Petitioner and Patent Owner have stipulated to construe the term “chamber”
`
`Petition Requesting Inter Partes Review
`
`
`
`to mean “compartment within the reservoir.” (Ex-1005 at 2.) Petitioner submits that
`
`the claimed “chambers” be given such construction. (Ex-1003, ¶30.)
`
`C.
`“impeller”
`Petitioner submits that the term “impeller” should be given its plain and
`
`ordinary meaning. An impeller is a conventional and well-known component of
`
`rotary systems. (Ex-1003, ¶31.) An impeller may refer to a rotor (e.g., a blade,
`
`turbine, or rotating arm) that is used to create a pressure difference within a fluid.
`
`(Id.) The ’362 patent describes a “pumping means with an impeller for pumping the
`
`cooling liquid through a pumping housing.” (Ex-1001 at 6:30-31.) This is consistent
`
`with the plain and ordinary meaning of “impeller.” (Ex-1003, ¶31.)
`
`D.
`“radiator”
`Petitioner submits that the term “radiator” should be given its plain and
`
`ordinary meaning. A radiator is a conventional and well-known component included
`
`in systems that require cooling. (Ex-1003, ¶32.) In its plain meaning radiators are
`
`understood by a POSITA as a system that transfers thermal energy (e.g., heat) from
`
`one medium to another medium. (Id.) This is consistent with the ’362 patent, which
`
`states that a radiator may serve “as a means for removing the heat from the liquid by
`
`means of the air fan 10 blowing air through the heat radiator.” (Ex-1001 at 8:17-19
`
`7
`
`

`

`U.S. Patent No. 8,240,362
`IPR2023-00667
`and FIG. 3.) Radiators may include structures such as pipes or fins to transfer heat.
`
`Petition Requesting Inter Partes Review
`
`
`
`(Ex-1003, ¶32.)
`
`E. Other Terms
`Petitioner does not believe any additional constructions are required at this
`
`time. Accordingly, all other terms of the ’362 patent have been given their ordinary
`
`and customary meaning in this Petition. Petitioner reserves the right to respond to
`
`claim construction positions raised by the Board or Patent Owner. (Ex-1003, ¶33.)
`
`VI. OVERVIEW OF PRIOR ART
`A.
`Batchelder (Ex-1006)
`Batchelder issued as U.S. Patent No. 6,019,165 on February 1, 2000.
`
`(Ex-1006, [11], [45].) Thus, Batchelder is prior art to the ’362 patent under at least
`
`pre-AIA 35 U.S.C. §102(a) for all Challenged Claims. Batchelder was identified in
`
`an Information Disclosure Statement (IDS) at the time the ’362 patent was filed (Ex-
`
`1002, 764-FH at 333); however, it was not cited by the Examiner.
`
`B.
`Shin (Ex-1007)
`Shin was filed as Japanese Patent Application 2000-345470 on November 8,
`
`2000 and published on May 24, 2002 as Japanese Unexamined Patent Application
`
`Publication No. 2002-151638 to Takayuki Shin. (Ex-1007, (21), (22), (11), (43).)
`
`Thus, Shin is entitled to an effective filing date of at least May 24, 2002. Shin is
