`
`with over 10 of years working with thermal management of electronics, with a
`
`Petition Requesting Inter Partes Review
`
`
`
`major thrust being liquid cooling in various contexts. (Ex. 1003 at ¶¶2-7.)
`
`IV. OVERVIEW OF THE ’355 PATENT
`The ’355 patent relates to a liquid-cooling system for a computer system. The
`
`specification purports to disclose embodiments of a liquid-cooling system that is
`
`more efficient, easier to use, and more compact with integrated components than
`
`prior art cooling systems. (Ex. 1001 at 1:12-2:24.) The ’355 patent explains that it
`
`provides an “integrate element” to limit the number of separate elements and
`
`provides an “entire pump [that] is a placed inside the reservoir” or placed “outside
`
`the reservoir in the immediate vicinity of the reservoir.” (Id. at 2:17-18 and 2:25-
`
`29). The ’355 patent further states (and subsequently claims) that these purported
`
`improvements may be achieved by having an integrated element comprising the heat
`
`exchange interface, the reservoir of cooling liquid, and the pump for pumping the
`
`cooling liquid. (Id. at 1:53-2:36; claims 1-16; Ex. 1003 at ¶¶33-36.) As shown in
`
`detail in this Petition, however, the Challenged Claims of the ’355 patent are
`
`not inventive.
`
`A.
`Person of Ordinary Skill in the Art (“POSITA”)
`A POSITA in the field of the ’355 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

`
`
`
`related field, and would have possessed at least two or three years of specialized in
`
`liquid cooling systems for computer systems or in similar systems. A person with
`
`less education but more relevant practical experience, depending on the nature of
`
`that experience and degree of exposure to liquid cooling systems for computer
`
`systems, could also qualify as a POSITA in the field of the ’355 patent. (Ex. 1003
`
`at ¶¶ 14-19.)

`
`would have understood that the tube “inlet” connection and the tube “outlet”
`
`connection mentioned here “are connected to a heat radiator by means of connecting
`
`tubes 24 and 25” as shown in FIG. 7 discussed above (Id. at 16:19-23; FIG. 7.)
`
`“The radiator may be placed nearby or distant from the reservoir housing 14,
`
`depending on the set-up of the computer system. In one possible embodiment, the
`
`radiator is placed in the immediate vicinity of the reservoir, thereby possible

`
`(Id., 22:39-48).
`
`“The reservoir housing 14 has a recess 40 in the centre on the upper side of

`Priority Date
`The ’355 patent issued on September 18, 2018, from Application No.
`
`15/626/706 filed on June 19, 2017 and claims the benefit of Application No.
`
`11/919,974, which
`
`is a U.S. National Stage of
`
`Int’l application No.
`
`PCT/DK2005/000310, filed on May 6, 2005. Petitioner does not concede that the
`
`’355 patent is entitled to an effective filing date of May 6, 2005, 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) (explaining that “the burden …
`

`
`
`
`double patenting rejections. (Id. at 448-49.) On July 15, 2018, the Examiner
`

`
`made a supplemental amendment. Thereafter, a notice of allowance issued without
`
`a prior art rejection on the merits. (Id. at 468-72.)
`
`E. Admitted Prior Art (“APA”)
`Prior art admissions made in the specification of a patent application are
`
`binding on a Patent Owner, and may be used as prior art against the patent.
`
`PharmaStem Therapeutics, Inc. v. ViaCell, Inc., 491 F.3d 1342, 1362 (Fed. Cir.
`
`2007) (“Admissions in the specification regarding the prior art are binding on the
`
`patentee for purposes of a later inquiry into obviousness.”). Patent Owner made
`
`such admissions here. FIGS. 1-2 of the ’355 patent show a prior art embodiment of
`
`“the typical components in an air-cooling type CPU cooling arrangement,” and
`
`FIG. 3 shows an embodiment of “the typical components in a liquid-cooling type
`
`CPU cooling arrangement.” (Ex. 1001 at 9:40-48, 10:22-67; FIGS. 1-3.) See In re
`
`Cohen, 767 Fed. Appx. 985, 987-89 (Fed. Cir. 2019) (affirming an examiner’s
`
`reliance on the disclosure of a “typical” technique in the “Background” section of a
`
`patent as applicant-admitted prior art). (See also Ex. 1003 at ¶¶45-47.)

`
`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.”
`
`
`“reservoir”
`The parties have stipulated, in the pending district court action, to construe
`
`the term “reservoir,” as that term is used in claims 1, 10, and 11 of the ’355 patent,
`
`to mean “single receptacle defining a fluid flow path.” (Ex. 1004 at 1.) With respect
`
`to claim 1, the reservoir is claimed to include “a pump chamber,” “a thermal
`
`exchange chamber,” and “a heat-exchanging interface.” With respect to claim 10,
`
`the reservoir is claimed to comprise “a pump chamber,” “a first passage,” and “a
`
`heat exchanging interface.” Thus, the claims are drafted such that the reservoir refers
`
`to an overarching collection of components that form a single receptacle defining a
`
`fluid flow path. (Ex. 1003 at ¶21.)
`
`
`“chamber”
`The parties have stipulated to construe the term “chamber,” as that term is
`
`used in claims 1, 2, and 10 of the ’355 patent, to mean “compartment within the
`
`reservoir.” (Ex. 1004 at 2.) The claims are directed to both a “pump chamber” and
`
`a “thermal exchange chamber.” Petitioner submits that these claimed “chambers”

`

`
`
`
`construction for “chamber” above. (Ex. 1003 at ¶22.)
`
`
`“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 at ¶23). An impeller may refer to a rotor (e.g., a blade,
`
`turbine, or rotating arm) that is used to create a pressure differential within a fluid.
`
`(Id.) The ’355 patent describes “pumping means with an impeller for pumping the
`
`cooling liquid through a pumping housing.” (Ex. 1001 at 8:58-63.) This is
`
`consistent with the plain and ordinary meaning of “impeller.” (Ex. 1003 at ¶23.)

`Petition Requesting Inter Partes Review
`
`
`“stator”
`Petitioner submits that the term “stator” should be given its plain and
`
`ordinary meaning as the stationary functional parts of a motor during its operation.
`
`A stator is a conventional and well-known component of rotary motors. (Ex. 1003
`
`at ¶24). For example, the ’355 patent explains, “wherein a stationary part of the
`
`motor of the pump, such as a stator of an electrical motor, is placed outside the
`
`reservoir.” (Ex. 1001 at 2:40-42.). Typically, a component that rotates is coupled
`
`to the stator such that the rotating component moves about an axis defined by the
`
`stator. (Ex. 1003 at ¶24).
`
`In the context of electro-magnetic motors, a “stator” may be interchangeable
`
`with the phrase “stator assembly” such that the stator is in a fixed position while a
`
`magnetic rotor rotates in response to magnetic fields created by the stator coil
`
`included in the stator assembly. (See e.g., Ex. 1008 at 5:10-17; see also Ex. 1009 at
`
`Abstract). Thus, a stator may refer to an assembly including a coil used in rotary
`
`motor applications. (Ex. 1003 at ¶25.)
`
`
`“an inlet … positioned below a center of the impeller”
`Petitioner submits that the term “an inlet … below a center of the impeller”
`
`encompasses an “opening for fluid entrance near the center of the impeller along the
`
`axis around which the impeller rotates.” The term “below a center of the impeller”
`
`in the context of an impeller does not appear in the written description of the ’355

`entire opening into the cavity that the pump chamber configures, said cavity being
`
`in direct communication with the interior of the reservoir housing 14 as such.” (Ex.

`
`
`
`(Ex. 1001 at FIG. 20 (circle added to show inlet).) As depicted above, FIG. 20 shows
`
`an inlet opening (area within the red square) positioned near a center of the impeller
