`
`Detailed Action
`
`Notice of Pre-AlA or AIA Status
`
`1.
`
`The present application, filed on or after March 16, 2013, is being examined
`
`under the first inventor to file provisions of the AIA.
`
`In the event the determination of the status of the application as subject to AIA 35
`
`U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103)is incorrect, any
`
`correction of the statutory basis for the rejection will not be considered a new ground of
`
`rejection if the prior art relied upon, and the rationale supporting the rejection, would be
`
`the same under either status.
`
`Response to Arguments
`
`2.
`
`Applicant's arguments with respect to claims 1-8 and 15 have been considered
`
`but are moot because the new ground of rejection does not rely on the primary
`
`reference (Bunyan (WO 2017/172703) applied in the prior rejection of record for any
`
`teaching or matter specifically challenged in the argument.
`
`Claim Objections
`
`3.
`
`Claims 2 and 5-7 are objected to becauseof the following informalities:
`
`a.
`
`Claim 2, line 8, “first surface” should be “thefirst surface” having
`
`antecedencein line 2;
`
`b.
`
`Claim 2, line 11, “second surface” should be “the second surface” having
`
`antecedencein line 3;
`
`C.
`
`Claim 5, line 9, “a pressing component” should be “the pressing
`
`component” having antecedencein lines 3-4;

`
`e.
`
`Claim 5, line 22, “second surface” should be “the second surface” having
`

`
`Appropriate correction is required.
`
`Claim Rejections - 35 USC § 103
`
`4.
`
`The following is a quotation of 35 U.S.C. 103 which forms the basis for all
`
`obviousnessrejections setforth in this Office action:
`
`A patent for a claimed invention may not be obtained, notwithstanding that the claimed
`invention is not identically disclosed as set forth in section 102 of thistitle, if the differences
`between the claimed invention andthe prior art are such that the claimed invention as a whole
`would have been obvious before the effectivefiling date of the claimed invention to a person
`having ordinary skill in the art to which the claimed invention pertains. Patentability shall not
`be negated by the manner in whichthe invention was made.
`
`5.
`
`Claims 1 and 15 are rejected under AIA 35 U.S.C. 103 as being unpatentable
`
`over Hu (US 8,896,110) and Murakami (US 2020/0024496).
`
`With respect to Claim 1, Hu teachesan electronic device(fig. 1, 100) comprising:
`
`a mount board (104); a heat generating component (108) provided on the mount board;
`
`a pressing component (114) provided above the heat generating component; andafilm
`
`(110) provided between the heat generating component and the pressing component,
`
`wherein: the film contains graphite-based carbon (col. 3, |. 29), the heat generating
`
`component is provided between (see fig. 1) the mount board and the pressing
`
`component, the heat generating component and the film are sealed (using 112) with the
`
`mount board and the pressing component by connecting the mount board and the
`
`pressing component, and the film is compressed(col. 5, |. 19) by connecting the mount
`
`board and the pressing component and heat generating component.
`
`Hu fails to
`
`

`

`Application/Control Number: 17/050,429
`Art Unit: 2835
`
`Page 4
`
`disclose a liquid heat conductive material provided between the heat generating
`
`component and the film and between the pressing component and the film, wherein: the
`
`film contains graphite-based carbon. Murakami teaches a liquid ({[0055], Il. 2-5) heat
`
`conductive material (oil is a thermally conductive material and resulting oil coatedfilm is
`
`q[0058], Il. 39) provided between (4[0052], |. 9) the heat generating component({[0061],
`
`|. 4) and the film and between the pressing component ({[0061], Il. 5-6) and the film,
`
`wherein: the film contains graphite-based carbon (4[0040], |. 1).
`
`It would have been
`
`obvious to one of ordinary skill in the art before the effectivefiling date of the claimed
`
`invention to substitute the liquid heart conductive coated film of Murakami for that of Hu
`
`for the purposeof providing “the thermal interface material having excellent thermal
`
`coupling properties compared with that of the conventional composite TIM, the possible
`
`application for practical materials having unevenness compared with invention of Patent
`
`Document 1, and the extremely decreased pressure dependenceof the thermal
`
`resistance can be provided’ ({][0032]).
`
`With respect to Claim 15, Chrysler further teaches the pressing componentis
`
`fixed to the mount board by an adhesive (col. 4, I. 42).
`
`6.
`
`Claims 2, 5, and 6 are rejected under AIA 35 U.S.C. 103 as being
`
`unpatentable over Hu (US 8,896,110), Murakami (US 2020/0024496) and Fukui (US
`
`2016/0336253).
`
`With respect to Claim 2, Hu and Murakami discloses the claimed invention
`
`including one or morefirst voids (Murakami, fig. 3b, area above 3b) are formedatafirst
`
`surface (Murakami, fig. 36, top surface of 3b) of the film (Sb) facing the heat generating
`
`component (Murakami, [0061], |. 4), and one or more second voids (Murakami, fig. 3b,
`
`

`

`Application/Control Number: 17/050,429
`Art Unit: 2835
`
`Page 5
`
`area below 3b) are formed at a second surface (Murakami, fig. 3b, top surface of 3b) of
`
`the film (Murakami, 3b) facing the pressing component (Murakami, §[0061], Il. 5-6),
`
`the
`
`one or morefirst voids (Murakami, fig. 36, area above 3b) and the one or more second
`
`voids (Murakami, fig. 3b, area below 3b) are filled with the liquid heat conductive
`
`material (Murakami, 3a). Hu and Murakami fail to disclose when a first porosity is a
`
`ratio of a total area of the one or morefirst voids projected onto first surface to an entire
`
`area of the first surface, the first porosity is less than or equal to 5%, and when a
`
`second porosity is a ratio of a total area of the one or more second voids projected onto
`
`second surface to an entire area of the second surface, the second porosity is less than
`
`or equal to 5%. Fukui teaches one or morefirst voids ({[0089, I. 14) are formed ata
`
`first surface (surface of solder facing silicon device) of the film ([0089], I. 8, solder)
`
`facing the heat generating component ([0089], Il. 5-6, silicon device), and one or more
`
`second voids ({[0089, |. 14) are formed at a second surface (surface of solder facing
`
`heat dissipation substrate) of the film ({[0089], |. 8, solder) facing the pressing
`
`component (4[0089], |. 5, heat dissipation substrate), the one or morefirst voids and the
`
`one or more second voidsarefilled with the heat conductive material ({[0089], |. 8,
`
`solder), whenafirst porosity is a ratio of a total area of the one or morefirst voids
`
`projected ontofirst surface to an entire area ofthe first surface, the first porosity is less
`
`than or equal to 5% (4[0089], Il. 9-10), and when a second porosity is a ratio of a total
`
`area of the one or more second voids projected onto second surface to an entire area of
`
`the second surface, the second porosity is less than or equal to 5% (4[0089], Il. 9-10).
`
`It
`
`would have been obvious to one having ordinary skill in the art before the effectivefiling
`
`date of the claimed invention was made thatit is commonly knownthat there is no
`
`

`

`Application/Control Number: 17/050,429

`
`Page 6
`
`problem related to quality of the interface if the void percentage determined bythis
`
`measurement is 5%or lower (4[0089], Il. 12-16), since it has been held that discovering
`
`an optimum value of a result effective variable involves only routine skill in the art. /n re
`
`Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980). Fukui fails to disclose a porosity
`
`of the one or morefirst voids is less than or equal to 5%, and a porosity of the one or
`
`more secondvoids is less than or equal to 5%. It would have been obvious to one
`
`having ordinary skill in the art before the effective filing date of the claimed invention
`
`was made to for the voids of Fukui to be first and second voids on opposing sides of
`
`Fukui’s substrate for the purpose of an acceptable surface defect level to insure
`
`required heat transfer between the film and mating surfaces are met, since it has been
`
`held that mere duplication of the essential working parts of a device involves only
`
`routine skill in the art. St: Regis Paper Co. v. Bemis Co., 193 USPQ 8.
`
`Examiner Note: If a porosity of a void being less than or equal to
`
`5%is a critical characteristic of the invention (rather than just a desirable
`
`characteristic), can Applicant submit actual test data to show the criticality
`
`of this specific limitation that the invention functions at 5% and below and
`
`does not function above 5%.
`
`With respect to Claim 5, Hu teaches a method for manufacturing an electronic
`
`device (fig. 1, 100), the method comprising: preparing a mount board (104), on which a
`
`heat generating component (108) is mounted, and a pressing component
`
`(114); arranging a film (110) having graphite-based carbon (col. 3, |. 29) on the heat
`
`

`

`Application/Control Number: 17/050,429
`Art Unit: 2835
`
`Page 7
`
`generating component; arranging a pressing component (114) on the film; connecting
`
`(see fig. 2d) the mount board and the pressing component; sealing (using 112) the heat
`
`generating component and the film with (see fig. 2d) the mount board and the pressing
`
`component; compressing (col. 5, |. 19) the film by the pressing component.
`
`Hu fails to
`
`disclose forming one or morefirst voids at a first surface of the film facing the heat
`
`generating component, and forming one or more second voids at a second surface of
`
`the film facing the pressing component; and by emitting an ultrasonic wave from a side
`
`of the pressing component and detecting a reflected wave of the ultrasonic wave,
`
`examining a first porosity and a second porosity, when the first porosity is a ratio of a
`
`total area of the one or morefirst voids projected onto first surface to an entire area of
`
`the first surface, and the second porosity is a ratio of a total area of the one or more
`
`second voids projected onto second surface to an entire area of the second
`
`surface. Murakami teaches forming one or morefirst voids (fig. 3b, area above 3b) ata
`
`first surface (fig. 3b, top surface of 3b) of the film (3b) facing the heat generating
`
`component (§[0061], |. 4), and forming one or more secondvoids (fig. 3b, area below
`
`3b) at a second surface fig. 3b, bottom surface of 3b) of the film (Sb) facing the pressing
`
`component (§[0061], Il. 5-6) and providingafirst porosity (fig. 3b, area above 3b) anda
`
`second porosity (fig. 3b, area below 3b).
`
`It would have been obvious to one of ordinary
`
`skill in the art before the effective filing date of the claimed invention to substitute the
`
`liquid heart conductive coated film of Murakami for that of Hu for the purpose of
`
`providing “the thermal interface material having excellent thermal coupling properties
`
`comparedwith that of the conventional composite TIM, the possible application for
`
`practical materials having unevenness comparedwith invention of Patent Document1,
`
`

`

`Application/Control Number: 17/050,429
`Art Unit: 2835
`
`Page 8
`
`and the extremely decreased pressure dependenceof the thermal resistance can be
`
`provided” (¥][0032]). Hu and Murakami fail to disclose by emitting an ultrasonic wave
`
`from a side of the pressing component and detecting a reflected wave of the ultrasonic
`
`wave, examiningafirst porosity and a second porosity, when the first porosity is a ratio
`
`of a total area of the one or morefirst voids projected onto first surface to an entire area
`
`of the first surface, and the second porosity is a ratio of a total area of the one or more
`
`second voids projected onto second surface to an entire area of the second surface.
`
`Fukui teaches by emitting (4[0089], |. 9) an ultrasonic wave (4[0089], |. 9) from a side of
`
`the pressing component and detecting a reflected wave ({[0089], |. 9) of the ultrasonic
`
`wave, examiningafirst porosity (¢[0089, |. 14, on surface of solder facing silicon device)
`
`and a second porosity ({[0089], |. 14, on surface of solder facing heat dissipation
`
`substrate), when the first porosity is a ratio of a total area of the one or morefirst voids
`
`projected ontofirst surface to an entire area ofthe first surface, and the second porosity
`
`is a ratio of a total area of the one or more second voids projected onto second surface
`
`to an entire area of the second surface. It would have been obvious to one having
`
`ordinaryskill in the art before the effective filing date of the claimed invention was made
`
`that it is commonly knownthat no problem related to quality of the interface if the void
`
`percentage determined by this measurement is 5% or lower (F[0089], Il. 12-16), since it
`
`has been held that discovering an optimum value of a result effective variable involves
`
`only routine skill in the art. In re Boesch, 617 F.2d 272, 205 USPQ 215 (CCPA 1980). It
`
`would have been obvious to one having ordinary skill in the art before the effectivefiling
`
`date of the claimed invention was made to modify the device of Hu and Murakami with
`
`the ultrasonic waves of Fukui to provide as nondestructive means to insure the void
`
`

`

`Application/Control Number: 17/050,429
`Art Unit: 2835
`
`Page 9
`
`percentage is small enough that the operation of the electronic device is not affected by
`
`the size of the voids. Fukui fails to disclose emitting an ultrasonic wave from a side of
`
`the pressing component and examining whether the one or morefirst voids and the one
`
`or more second voids arefully filled with the liquid heat conductive material. It would be
`
`obvious to one of ordinary skill at the time of the invention, given the limited number of
`
`permutations of the sides that the ultrasonic wave can be emitted from (i.¢e., side of the
`
`pressing component, or side of heat generating component). The rationale to support a
`
`conclusion that the claim would have been obvious is that "a person of ordinary skill has
`
`good reason to pursue the known options within his or her technical grasp. If this leads
`
`to the anticipated success, it is likely that product [was] not of innovation but of ordinary
`
`skill and common sense. In that instance the fact that a combination was obvious to try
`
`might show that it was obvious under § 103." KSA, 550 U.S. _at_, 82 USPQ2d 1385, at
`
`1397 (2007). It would have been obvious to one having ordinary skill in the art before
`
`the effective filing date of the claimed invention was madeto for the voids of Fukui to be
`
`first and second voids on opposing sides of Fukui’s substrate for the purpose of an
`
`acceptable surface defect level to insure required heat transfer between the film and
`
`mating surfaces are met, since it has been held that mere duplication of the essential
`
`working parts of a device involves only routine skill in the art. St, Regis Paper Co.v.
`
`Bemis Co., 193 USPQ 8.
`
`With respect to claim 6, Hu and Murakami fail to disclose when the first porosity
`
`is greater, or the second porosity is greater than or equal to 5%, the electronic device is
`
`determined as a defective product. Fukui teaches when the first porosity is greater, or
`
`the second porosity is greater than or equal to 5%, the electronic device is determined
`
`

`

`Application/Control Number: 17/050,429
`Art Unit: 2835
`
`Page 10
`
`as a defective product (¥[0089], Il. 10-11).
`
`It would have been obvious to one having
`
`ordinaryskill in the art before the effective filing date of the claimed invention was made
`
`to for the voids of Fukui to be first and second voids on opposing sides of Fukui’s
`
`substrate for the purpose of an acceptable surface defect level to insure required heat
`
`transfer between the film and mating surfaces are met, since it has been held that
`
`mere duplication of the essential working parts of a device involves only routine skill in
`
`the art. St. Regis Paper Co. v. Bemis Co., 193 USPQ 8.
`
`7.
`
`Claim 3 is rejected under AIA 35 U.S.C. 103 as being unpatentable over Hu (US
`
`8,896,110), Murakami (US 2020/0024496) and Tachibana (JP 2014-133669).
`
`Hu and Murakami disclose the claimed invention except for a compressibility of
`
`the film is more than or equal to 30%at a pressure of 100 kPa. Tachibana teaches a
`
`compressibility of the film (abs. |. 1) is more than or equal to 30% (density of 1.2
`
`g/cm equals 53%density which allows for compressibility of at least 30% when air is
`
`removed).
`
`It would have been obvious to one of ordinary skill in the art before the
`
`effectivefiling date of the claimed invention to substitute the film of Tachibana for thatof
`
`Hu and Murakami for the purposeofthe film exerting a force on mating parts to
`
`insure good thermal connection with the mating parts. Tachibana fails to
`
`specifically disclose compressibility is more than or equal to 30%at a pressure of 100
`
`kPa.
`
`It would have been obvious to one having ordinary skill in the art before the
`
`effective filing date of the claimed invention was made to for the pressure to be any
`
`pressureincluding that of 100 kPa that defines the amount of force applied to obtain
`
`the required compressibility value, since it has been held that discovering an optimum
`
`

`

`Application/Control Number: 17/050,429
`Art Unit: 2835
`
`Page 11
`
`value of a result effective variable involves only routine skill in the art. /n re Boesch, 617
`
`F.2d 272, 205 USPQ 215 (CCPA 1980).
`
`8.
`
`Claim 4 is rejected under AIA 35 U.S.C. 103 as being unpatentable over Hu (US
`
`8,896,110), Murakami (US 2020/0024496) and Greinke (US 6,746,768).
`
`Hu and Murakami disclose the claimed invention exceptfor the liquid heat
`
`conductive material has a kinematic viscosity at 25° C. ranging from 2 cSt to 15 cSt
`
`inclusive. Greinke teaches the heat conductive material has a kinematic viscosity at
`
`37.8° C. ranging from 1 cSt to 15 cSt inclusive (col. 10, Il. 35-38).
`
`It would have been
`
`obvious to one of ordinary skill in the art before the effectivefiling date of the claimed
`
`invention to substitute the liquid heat conductive material of Greinke for that of
`
`Murakami for the purposeof “the oil makes the graphite sheet "softer and more
`
`amenable to surface deformations and irregularities of the heat source/cooling module”
`
`(col. 9, Il. 57- 59) to reduce “air gaps (which act as thermal insulators between the
`
`surfaces of the thermal interface and the heat sink and/or the heat source”(col. 9,
`
`Il. 36-
`
`39). Greinke fails to specifically disclose the liquid heat conductive material has a
`
`kinematic viscosity at 25° C. ranging from 2 cSt to 15cSt inclusive. As temperature
`
`decreases from 37.8° C to 25° C, the kinematic viscosity increases, Greinke’s 1 cSt to
`
`15 cSt kinematic viscosity will still be in the required range of 2 cSt to 15cSt at 25° C.

`
`Claim 7 is rejected under AIA 35 U.S.C. 103 as being unpatentable over Hu (US
`
`8,896,110), Murakami (US 2020/0024496) and Fisher (US 7,700,162).
`
`Hu and Murakami disclose the claimed invention except for side surfaces of the
`
`film are covered with the liquid heat conductive material. Fisher teaches side surfaces
`
`(fig. 3, 1b at left & right sides of 1) of the film (1) are covered with the liquid heat

`
`conductive material, and the side surfaces are disposed (see fig. 3) between the first
`
`surface and the second surface.
`
`It would have been obvious to one of ordinary skill in
`
`the art before the effective filing date of the claimed invention to modify the device of Hu
`
`and Murakami with the covered side surfaces of Fisher for the purpose of providing a
`
`protective layer (col. 1,
`
`Il. 57-58) to the side surfaces of the film.
`
`10.
`
`Claim 8 is rejected under AIA 35 U.S.C. 103 as being unpatentable over Hu (US
`
`8,896,110), Murakami (US 2020/0024496) and Sayir (US 2007/0053168).
`
`Hu and Murakami disclose the claimed invention exceptfor the liquid heat
`
`conductive material contains perfluoropolyether. Sayir teaches the liquid heat
`
`conductive material contains perfluoropolyether ({[0050], |. 9).
`
`It would have been
`
`obvious to one of ordinary skill in the art before the effectivefiling date of the claimed
`
`invention to substitute the PFPE of Sayir for the oil of Murakami for the purposeof
`
`providing “moisture resistance, structural integrity, and handling strength, i.e. stiffness
`
`for the graphite layer, as well as "fixing" the morphology of the graphite layer” (q[0050),
`
`Il. 13-15).
`
`Conclusion
`
`11.
`
`The prior art made of record and notrelied upon is considered pertinent to
`
`applicant's disclosure. US 6,835,453 discloses a graphite layer coated with a liquid/solid
`
`phase changelayer. US 6,653,730, 6,706,562 and 7,098,079 disclose a mounting
`
`board and a pressing member sandwiching a heat generating component and a
`
`graphite basedfilm. US 5,545,473 discloses a compressible film between a heat
`
`generating component and a pressing component.
