`
`Page 3
`
`claimed invention a nd the priorartare such that the claimed invention as a whole would have
`been obvious before the effective fi ling date ofthe claimed invention to a person havingordinary
`
`skill inthe artto whichthe claimed invention pertains. Patenta bility shall not be negated bythe
`manner in which the i nventi on was made.
`
`Claims 1-4 and 8 are rejected under 35 U.S.C. 103 as being unpatentable over Katsuda
`
`(US 2005/0151894)
`
`in view of Mizumaki (US 2005/0099604), and in further view of Okazaki
`
`(JP 2007/024913;
`
`the English translation attached).
`
`Regarding claim 1, Katsuda discloses a display device comprising:
`
`a display panel (22 in Figs. 26A and 26B);
`
`a firstframe (21) includinga frame portion (the top portion of21) covering a peripheral
`
`portion of a display surface of the display panel;
`
`a secondframe (23) includinga panel support (the top portion of 23) sandwichingthe
`
`display panel with the frame portion;
`
`an optical sheet(24 and 25) that is opposite to the display panel in a first direction (the
`
`vertical direction in Figs. 26A and 26B), an outerperipheral end ofthe optical sheet being
`
`opposite to the panel support (see Figs. 26A and 26B);
`
`a diffusing substrate (26) on which the optical sheetis disposed;
`
`a third frame (103) includinga main body (103a and 103b) having an accommodation
`
`space in which a plurality of lightemitti ngelements are accommodated (25 accommodated on
`
`103; see Figs. 25A and 25B; see [0106]—[0109]
`
`identifyingthe embodiment shown in Figs. 25A—
`
`26B), and a substrate support (103c) extendingfrom the main body (see Fig. 26A) to support
`
`the diffusing substrate; and
`
`

`

`Application/Control Number: 16/017,548
`Art Unit: 2871
`
`Page 4
`
`a plurality ofspacer members (see at least BS, Bl and BZ; [0248] ”forming a gap")
`
`disposed betweenthe panel support and the substrate support,
`
`wherein
`
`the optical sheet and the panel support are disposed witha space interposed
`
`therebetween inthe first direction (see Fig. 26A), and
`
`Katsuda does not disclose each of the plurality of spacer members includes a restriction
`
`unit that restricts movement of the diffusing substrate inthe first direction.
`
`Mizumaki teaches a spacer member includesa restriction unit that restricts movement
`
`of the diffusing substrate inthe fi rst direction (see Figs. 21A—213 where the optical sheet 14 is
`
`restricted by the pin—like member70 and the screw 81; [0095] ”This permits the upper and
`
`lowerframes 71 and 72 that are put togetherto be fixed together" teaching 71 and 72 are
`
`verticallyfixed together).
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date of the invention to modify the Katsuda liquid crystal display with the
`
`teachings of Mizumaki, wherein each of the plurality of spacer members includes a restriction
`
`unit that restricts movement of the diffusing substrate inthe first direction, by having the pin —
`
`like memberand the screw of Mizumaki. One would have been motivated to prevent the
`
`optical sheetfrom movingwhile puttingthe upperand lowerframes togetheras taught by
`
`Mizumaki ([0075]).
`
`Katsuda does not disclose the diffusing substrate is transparent.
`
`

`
`Okazaki teachesa diffusing substrate beingtransparent (see 11d in Figs. 1 and 4; [0003]
`
`"an optical sheet set 11 including
`
`a fourth optical sheet 11d
`
`and spectral transmission
`
`characte ristics").
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date of the invention to modify the Katsuda liquid crystal display with the
`
`teachings ofOkazaki, wherein a diffusi ng substrate isa transparent substrate, by havinga
`
`transparent mate rial for the diffusing substrate, where Katsuda is silent regarding the specific
`
`material, Okazaki teaches an appropriate and suitable material for a diffusing substrate, and
`
`where "the selection ofa known mate rial based on its suitability forits intended use supports a
`
`prima facie obviousness determination" (see MPEP 2144.07).
`
`Regarding claim 2, Katsuda, Mizumaki and Okazaki disclose the limitations ofclaim 1
`
`above.
`
`Katsuda does not disclose that the restriction unit restricts movement ofthe diffusing
`
`substrate in a second direction orthogonal to the first direction.
`
`Mizumaki teaches a restriction unit restricts movement ofthe diffusing substrate (14;
`
`[0058] ”The optical sheet 14
`
`include:
`
`a diffusive sheet") in a second direction orthogonal to
`
`the first direction (see Figs. 21A—22 where the projection portion 14a of the optical sheetis
`
`fixed; [0063] ”restricts the movement of the optical sheet 14 in the X direction").
`
`It would have been obviousto one of ordinary skill inthe art at a time before the
`
`effective filing date ofthe invention to modifythe device disclosed by Katsuda and Okazaki with
`
`the teachings of Mizumaki, wherein the restriction unit restricts movement of the diffusing
`
`

`

`Application/Control Number: 16/017,548
`Art Unit: 2871
`
`Page 6
`
`substrate in a second direction orthogonal to the first direction, by having the pin—like member
`
`and the screw of Mizumaki. One would have been motivated to preventthe optical sheet from
`
`movingwhile puttingthe upper and lowerframes togetheras taught by Mizumaki ([0075]).
`
`Katsuda does not disclose the diffusing substrate is transparent.
`
`Okazaki teachesa diffusing substrate beingtransparent (see 11d in Figs. 1 and 4; [0003]
`
`"an optical sheet set 11 including
`
`a fourth optical sheet 11d
`
`and spectral transmission
`
`characte ristics").
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date of the invention to modify the Katsuda liquid crystal display with the
`
`teachings ofOkazaki, wherein a diffusi ng substrate isa transparent substrate, by havinga
`
`transparent mate rial for the diffusing substrate, where Katsuda is silent regarding the specific
`
`material, Okazaki teaches an appropriate and suitable material for a diffusing substrate, and
`
`where "the selection ofa known mate rial based on its suitability forits intended use supports a
`
`prima facie obviousness determination" (see MPEP 2144.07).
`
`Regarding claim 3, Katsuda, Mizumaki and Okazaki disclose the limitations of claim 2
`
`above.
`
`However, Katsuda does not disclose that the restriction unit isa recess in which an outer
`
`peripheral end of the diffusing substrate isaccommodated, and
`
`the recessincludesa firstinnersurface facing a principal surface ofthe diffusing
`
`substrate and a second inner surface that is orthogonal to the first inner surface and faces a
`
`side surface of the diffusing substrate.
`
`

`

`Application/Control Number: 16/017,548
`Art Unit: 2871
`
`Page 7
`
`Mizumaki teaches a restriction unit is a recess (13a in Fig. 22; [0060] ”a recessed portion
`
`13 a") in which an outer peripheral end ofa diffusing substrate (14; [0058] ”The optical sheet
`
`14
`
`include:
`
`a diffusive sheet") is accommodated (see Fig. 22), and
`
`the recess includesa firstinnersurface facing a principal surface of the diffusing
`
`substrate (see the bottom surface of 13a facing the principal surface of 14) and a second inner
`
`surface (see the side surface of 13a that isorthogonal to the bottom surface of 13a) that is
`
`orthogonal to the firstinner surface and faces a side surface of the diffusing substrate.
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date ofthe invention to modifythe device disclosed by Katsuda and Okazaki with
`
`the teachings of Mizumaki, wherein the restriction unit is a recess in which an outer peripheral
`
`end ofthe diffusing substrate is accommodated, and the recess includesa first innersurface
`
`facing a principal surface ofthe diffusing substrate and a second innersurface that is
`
`orthogonal to the first inner surface and faces a side surface of the diffusing substrate, by
`
`having the pin—like memberand the screw of Mizumaki. One would have been motivated to
`
`preventthe optical sheet from moving using the innersurfaceswhile puttingthe upper and
`
`lowerframes togetheras taught by Mizumaki (Fig. 22).
`
`Katsuda does not disclose the diffusing substrate is transparent.
`
`Okazaki teachesa diffusing substrate beingtransparent (see lid in Figs. 1 and 4; [0003]
`
`"an optical sheet set 11 including
`
`a fourth optical sheet 11d
`
`and spectral transmission
`
`characte ristics").
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date of the invention to modify the Katsuda liquid crystal display with the
`
`

`

`Application/Control Number: 16/017,548
`Art Unit: 2871
`
`Page 8
`
`teachings ofOkazaki, wherein a diffusi ng substrate isa transparent substrate, by havinga
`
`transparent mate rial for the diffusing substrate, where Katsuda is silent regarding the specific
`
`material, Okazaki teaches an appropriate and suitable material for a diffusing substrate, and
`
`where "the selection ofa known mate rial based on its suitability forits intended use supports a
`
`prima facie obviousness determination" (see MPEP 2144.07).
`
`Regarding claim 4, Katsuda, Mizumaki and Okazaki disclose the limitations of claim 1
`
`above.
`
`However, Katsuda does not explicitly disclose thata part ofthe outer peripheral end of
`
`the optical sheet is fixed to the third frame.
`
`Mizumaki teaches a part of the outer peripheral end of the optical sheet isfixed to a
`
`third frame (14 fixed to 72)
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date ofthe invention to modifythe device disclosed by Katsuda and Okazaki with
`
`the teachings of Mizumaki, wherein a part ofthe outer peripheral end of the optical sheet is
`
`fixed to a third frame, by havingthe pin—like memberand the screw of Mizumaki. One would
`
`have been motivated to preventthe optical sheet from movingwhile puttingthe upper and
`
`lowerframes togetheras taught by Mizumaki (Fig. 22).
`
`Katsuda furtherfailsto disclose that a cushion member is disposed betweenthe panel
`
`support ofthe secondframe and a peripheral region ofa part ofthe optical sheet which is fixed
`
`to the third frame.
`
`

`

`Application/Control Number: 16/017,548

`
`Page 9
`
`Okazaki teachesa cushion member(23 in Fig.4; [0018] ”cushioning material 23”) is
`
`disposed between a panel support of a second frame and a peripheral region ofa part of the
`
`optical sheetwhich is fixed to a third frame (23 disposed between a panel support which
`
`supports the display panel 2 and a peripheral region ofa part of the optical sheet 11 that is
`
`fixed to the frame 13).
`
`
`
`It would have been obviousto one of ordinary skill inthe art at a time before the
`
`effective filing date ofthe invention to modifythe device disclosed by Katsuda and Mizumaki
`
`with the teachings of Okazaki, wherein a cushion memberis disposed between the panel
`
`support of the second frame and a peripheral region of a part of the optical sheet which is fixed
`
`to the third frame, by havingthe cushioning material as taught by Okazaki. One would have
`
`been motivated to add the cushioning material between the panel support and the optical

`
`Page 10
`
`sheet so as to press the hanging portion of the optical sheet and prevent the dust due to
`
`friction of the optical sheet as taught by Okazaki ([0011]—[0012]).
`
`Regarding claim 8, Katsuda, Mizumaki and Okazaki disclose the limitations of claim 1
`
`above, and Katsuda further discloses a gap exists at a corner of the second frame (see the gap
`
`at the corner of 23).
`
`However, Katsuda does not disclose a cushion memberclosingthe gap is disposed
`
`between the second frame and the third frame.
`
`Okazaki teachesa cushion member (23 in Fig.4) closingthe gap is disposed betweenthe
`
`second frame and the third frame.
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date of the invention to modify the device disclosed by Katsuda and Mizumaki
`
`with the teachings of Okazaki, wherein a cushion memberclosingthe gap is disposed between
`
`the secondframe and the third frame, by having the cushioning material as taught by Okazaki.
`
`One would have been motivated to add the cushioning material between the second frame and
`
`the third frame so as to press the hanging portion of the optical sheet and preventthe dust due
`
`to friction ofthe optical sheet as taught by Okazaki ([0011]—[0012]).
`
`Claims 5-6 are rejected under 35 U.S.C. 103 as being unpatentable over Katsuda in
`
`view of Mizumaki and Okazaki, and in further view of Fukayama (US 2002/0080298).
`
`

`

`Application/Control Number: 16/017,548
`Art Unit: 2871
`
`Page 11
`
`Regarding claim 5, Katsuda, Mizumaki and Okazaki disclose the limitations of claim4
`
`above, and Katsuda further disclosesthat the optical sheet has an elongated shape in planar
`
`view(see Fig.2).
`
`Katsuda does not disclose that central portions of both ends in a longitudinal direction
`
`of the optical sheet are fixed to the third frame.
`
`Fukayama teaches central portions of both ends in a longitudinal direction ofthe optical
`
`sheet are fixed to a third frame (see Figs. 1 and 7 where the central portions of both ends ofthe
`
`optical sheet OPS are fixed to the lowerframe MCA; Regarding the term ”central portions", the
`
`examinerconsidersthat ”central” means in, at, or near the center).
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date ofthe invention to modifythe device disclosed by Katsuda, Mizumaki and
`
`Okazaki with the teachings of Fukayama, wherein central portions of both ends in a longitudinal
`
`direction of the optical sheet are fixed to the third frame, as the central portions are taught by
`
`Fukayama. One would have been motivated to consider a fixingside or a positioningfunction of
`
`the optical sheet to reduce wrinkles or the like (Fukayama: [0152] —[0153]).
`
`Regarding claim 6, Katsuda, Mizumaki, Okazaki and Fukayama disclose the limitations of
`
`claim 5 above.
`
`While Mizumaki discloses the optical sheet includes protrusions protruding outward
`
`from the central portions of an end in planar view, and the optical sheet isfixed to a third frame
`
`at the protrusion (see Figs. 8 and 21A—22), Mizumaki does not disclose the optical sheet
`
`

`

`Application/Control Number: 16/017,548
`Art Unit: 2871
`
`Page 12
`
`includes protrusions protruding outward from the central portions of both the ends in the
`
`longitudinal direction in planar view.
`
`Fukayama teaches an optical sheet includes protrusions protruding outward from the
`
`central portions of both the ends inthe longitudinal direction in planar view (see OPS including
`
`TAB—C in Figs. 1 and 7; Regardingthe term ”central portions", the examinerconsidersthat
`
`I"
`”centra means in, at, or near the center).
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date of the invention to modify the device disclosed by Katsuda, Mizumaki and
`
`Okazaki with the teachings of Fukayama, whereinthe optical sheetincludes protrusions
`
`protruding outward from the central portions of both the ends in the longitudinal direction in
`
`planarview, as the central portions are taught by Fukayama. One would have been motivated
`
`to consider a fixing side or a positioningfunction ofthe optical sheet to reduce wrinkles orthe
`
`like (Fukayama: [0152]—[0153]).
`
`Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Katsuda in view of
`
`Mizumaki and Okazaki, and in further view of Liu (US 2013/0039021).
`
`Regarding claim 7, Katsuda, Mizumaki and Okazaki disclose the limitations of claim 1
`
`above, and Katsuda furtherdisclosesthe first frame includesa plate—shapedfirst sidewall (see
`
`the vertical portion of 21 in Figs. 26A—26B) extendingfrom the frame portion toward a side of
`
`the third frame in the first direction,
`
`the substrate support ofthe third frame extendsintoa plate shape toward the first
`
`sidewall (see 103c extendingintoa plate shape toward the vertical portion of 21),
`
`

`

`Application/Control Number: 16/017,548
`Art Unit: 2871
`
`Page 13
`
`the second frame passes through a gap between the first sidewall and the substrate
`
`support (see 23in Figs. 26A—26B passesthrough a gap between the vertical portion of 21 and
`
`103c) and has a plate—shaped second sidewall extendingfrom the panel support toward the
`
`side of the third frame in the first direction (see the vertical portion of 23 extendingfrom the
`
`top portion of 23 toward the side of 103).
`
`However, Katsuda does not disclose that the second sidewall includesa bent portion
`
`bent along a principal surface at an end of the substrate support and a side surface orthogonal
`
`to the principal surface.
`
`Liu teaches a second sidewall (see the portion of 30 disposed between48 and 24in Fig.
`
`3) includesa bent portion (see the horizontal portion) bent alonga principal surface at an end
`
`of a substrate support and a side surface (see the vertical portion) orthogonal to the principal
`
`surface.
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date ofthe invention to modifythe device disclosed by Katsuda, Mizumaki and
`
`Okazaki with the teachings of Li u, whereinthe second sidewall includes a bent portion bent
`
`along a principal surface at an end ofthe substrate support and a side surface orthogonal to the
`
`principal surface, by havingthe shape of the frame as described by Liu. One would have been
`
`motivated to do so in order to hold the optical members togetherwith the backlight unit case
`
`(Liu: [00501-[0051]).
`
`Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Katsuda in view of
`

`
`Regarding claim 9, Katsuda, Mizumaki and Okazaki disclose the limitations of claim 1
`
`above.
`
`While Okazaki discloses a diffusing substrate beinga transparent substrate, Okazaki
`
`does not disclose the transparent substrate is a glass plate.
`
`Sakamoto teaches a transparent substrate isa glass plate ([0038] "The diffusing plate 8
`
`comprises a memberhaving transparency of a transparent resin, glass or the like" ).
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date of the invention to modify the device disclosed by Katsuda, Mizumaki and
`
`Okazaki with the teachings of Sakamoto, wherein the transparent substrate isa glass plate,
`
`where Okazaki is silent regarding the glass mate rial, Sakamoto teachesan appropriate and
`
`suitable material for a diffusing and transparent substrate, and where "the selection ofa known
`
`material based on its suitabilityforits intended use supportsa prima facie obviousness
`
`dete rmination" (see MPEP 2144.07).
`
`Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Katsuda in view of
`
`Mizumaki and Okazaki, and in further view of Nakamoto (US 2010/0033655).
`
`Regarding claim 10, Katsuda, Mizumaki and Okazaki disclose the limitations ofclaim 1
`
`above.
`
`However, Katsuda does not disclose that the display panel includes a first display panel
`
`that is ofa liquid crystal display panel and a second display panelthat isofa liquid crystal
`
`display panel superimposed on the first display panel.

`
`Nakamoto teaches a display panel includesa first display panel that isof a liquid crystal
`
`display panel and a second display panel that is of a liquid crystal display panel superimposed
`
`on the first display panel (see ”FIRST LIQUID CRYSTAL PAN EL" and ”SECOND LIQUID CRYSTAL
`
`PANEL" in Fig.1).
`
`It would have been obviousto one of ordinary skill in the art at a time before the
`
`effective filing date ofthe invention to modifythe device disclosed by Katsuda, Mizumaki and
`
`Okazaki with the teachings of Nakamoto, wherein the display panel includes a first display panel
`
`that is of a liquid crystal display panel and a second display panel that isof a liquid crystal
`
`display panel superimposed on the first display panel, by havingtwo liquid crystal panelsfor a
`
`liquid crystal display apparatus as taught by Nakamoto. One would have been motivated to
`
`have two display panelsto obtain high displayqualitywith no interference fringes by
`
`introducing, for example an interlace method to drive the first display panel and a progressive
`
`method to drive the second display panel (Nakamoto: [Abstract], [0045] —[0047]).
