`
`II.
`
`THE ’974 PATENT
`
`A.
`
`Overview of LCD Backlighting Principles
`
`18. By the time of the patent application to which the ‘974 patent claims
`
`priority Gune 1995), liquid crystal display (“LCD”) technology had progressed to
`
`commercial status and was used in products ranging from mobile phones and pagers
`
`Page 8 of 61
`
`
`
`to notebook computers and PC monitors. Small TVs based on LCD technology were
`
`also appearing in the market.
`
`19. An LCD is not a light emitting device, in contrast to plasma displays or
`
`patent is an example of a backlight that can be used in various products.

`20. The two types of backlights in use in the 1995 time frame are shown in
`
`the figure above. The upper portion of the diagram shows a “direct-lit” backlight and
`
`
`
`the lower diagram shows an “edge-lit” backlight. The ‘974 patent describes various
`
`edge-lit assemblies. In the above illustration, the light sources are LEDs, which is
`
`common today. In the 1995 time frame, cold cathode fluorescent lamps (CCFL) were
`
`also commonly used in either type of backlight unit. To achieve a small overall
`
`thickness, thin CCFL lamps or small LED packages were typically used. Depending
`
`on the brightness requirements, two lamp assemblies were often used for edge-lit
`
`backlight assemblies, one on either end of the light guide panel.
`
`21.
`
`Prior to 1995, it was well—known that edge-lit backlight assemblies
`
`generally have three key parts:
`
`(1) the light source, (2) the light guide panel, and
`
`(3) the extraction means so that the light m the light guide can exit towards the LCD
`
`with appropriate uniformity and directionality. The light source was typically the
`
`same size as one edge of the light guide. To improve efficiency of the backlight
`
`assembly, reflectors were typically added behind the light source, especially for CCFL
`
`lamps. The light guide panel always included an area or region in which light from the
`
`source could better “homogenize” before being extracted by the extraction means.
`
`The extraction means were typically protrusions or depressions or painted scattering
`
`dots with variable density so as to extract light uniformly over the area of the light
`
`guide panel. Reflectors were usually added below the light guide panel and along the
`
`edges to improve efficiency.
`
`22. A typical extraction pattern for an edge-lit backlight assembly is shown
`
`below. The referenced prior art patents in this Declaration show other examples. In
`
`Page 10 of 61
`
`
`
`this top view illustration, light from a light source enters the light guide panel and is
`
`extracted less (lower density of dots) near the light source where the light intensity is
`
`higher and is extracted more (higher density of dots) away from the light source where
`
`the light intensity is lower.

`
`Overview of the ’974 Patent
`
`23.
`
`The ’974 patent is entitled “Light emitting panel assemblies.” Jeffery R.
`
`Parker is the single named inventor of the ’974 patent. The patent issued on
`
`October 14, 2008. The patent was filed on March 17, 2006, but claims priority to a
`
`series of related applications that each originate from application No. 08/495,176,
`
`filed on June 27, 1995, now U.S. Patent No. 5,613,751.
`
`24.
`
`The ’974 patent discloses a light emitting assembly that is received in a
`
`cavity or recess of a tray or housing. The panel includes a pattern of light extracting
`
`deformities on at least one of its surfaces that cause the light received from at least
`
`one LED light source to be emitted from the panel assembly. The tray or housing in
`
`which the panel member is received acts as end edge and/or side edge reflectors to
`
`
`
`reflect light back into the panel that would otherwise exit the panel.
`
`(Ex. 1001,
`
`Abstract)
`
`25.
`
`The tray or housing in which the light emitting panel is entirely received
`
`additionally provides structural support and has posts, tabs, or other structural
`
`features that provide a mount for mounting the light emitting panel assembly into a
`
`larger assembly or device.
`
`(Ex. 1001, claim 1.)
`
`26. The light emitting panel assembly is designed to generate and direct rays
`
`of light in a manner to best illuminate a display, e.g., a liquid crystal display (“LCD”).
`
`Typical design considerations include producing light with sufficient uniformity and
`
`brightness, while minimizing the assembly’s profile thickness and electrical power
`
`consumption.
`
`27. The light emitting panel assembly contains reflective or refractive
`
`surfaces for changing the path of a portion of the light emitted from the light source.
`
`The light is reflected and refracted by various internal features that spatially
`
`homogenize and control the angular distribution of the reflected/refracted light.
`
`C.
`
`Level of Ordinary Skill in the Art
`
`28. MBUSA has requested that I opine on the education and/or
`
`professional experience levels necessary for a person to be considered one of ordinary
`
`skill in the art with respect to the technology disclosed in the ’974 patent. To that
`
`end, lVEBUSA’s counsel has advised me that I should consider:
`
`the education of the
`
`inventors at the time of the filing;
`
`the character of the problems confronted in the
`
`Page 12 of 61
`
`
`
`prior art;
`
`the previous solutions to those problems; (iv) the rate of technological
`
`advancement in the art; (v) the complexity of the invention; and (vi) the typical
`
`education level of workers in the field.
`
`29.
`
`As noted above, the ’974 patent claims priority to an earlier patent
`
`application filed by Parker and others on June 27, 1995.
`
`I have thus considered, the
`
`’974 patent and the prior art references from the perspective one of ordinary skill in
`
`the art considering those same references in June 1995 would have possessed.
`
`30.
`
`A person of skill in the art with respect to the ’974 patent would have
`
`held at least a Bachelor’s degree in electrical engineering, physics, optics, or a related
`
`field as well as approximately three or more years of experience in the field of light
`
`panel design and assembly, or a related field. Additional graduate degrees may
`
`substitute for experience in the field, while additional experience in the field could
`
`substitute for formal education.
`
`31.
`
`The professional and educational qualifications I have detailed above
`
`demonstrate that I am a person of at least ordinary skill in the art with respect to the
`
`’974 patent.
`
`D.
`
`32.
`
`Challenged Claims
`
`The ’974 patent has 24 claims, of which four claims are independent.
`
`Counsel for MBUSA has informed me that this petition for z'mferpan‘e.r review
`
`concerns claims: 1, 3, 4, 5, 7, 8, 9 and 13 (collectively, the “Challenged Claims”). For
`
`
`
`convenience, I have reproduced claim 7, which is emblematic of the features disclosed
`
`by each of the claims, below:
`
`7[a]
`
`7 lb]
`
`A light emitting panel assembly comprising at least:
`a light emitting panel member having a light entrance surface and
`a light emitting surface,
`
`at least one LED light source positioned near or against the light
`entrance surface, and
`
`a tray or housing having a cavity or recess in which the panel
`member is entirely received,
`
`wherein the panel member has a pattern of light extracting
`deformities on or in at least one surface to cause light to be
`emitted from the light emitting surface of the panel member, and
`
`the tray or housing includes end walls and side walls that act as
`end edge reflectors and side edge reflectors for the panel member
`to reflect
`light
`that would otherwise exit
`the panel member
`through an end edge and/or side edge back into the panel
`member and toward the pattern of light extracting deformities for
`causing additional light
`to be emitted from the light emitting
`surface of the panel member,
`
`7[gl
`
`wherein the tray or housing has posts, tabs or other structural
`features that provide a mount or structural support for at least
`one other part or component, and
`
`7th]
`
`the tray or housing provides structural support
`member.
`
`to the panel
`
`E.
`
`Claim Construction
`
`33. MBUSA’s counsel has notified me that, in evaluating whether elements
`
`of the above claims are anticipated or obvious based on prior art, I should construe
`
`the claim terms to have their plain and ordinary meaning. I have also been informed
`
`that the words of each claim should be given their plain meaning unless the plain
`
`meaning is inconsistent with the ‘974 patent’s specification.
`
`Page 14 of61
`
`
`
`34.
`
`Independent claims 1, 7, and 13 each contain the term “deformities.”
`
`Claims 3, 4, and 5, each of which depend from claim 1, and claims 8 and 9, each of
`
`which depend from claim 7, all incorporate this phrase by reference. The
`
`specification of the ‘974 patent defines “deformities” as a “change in the shape or
`
`geometry of the panel surface and/or coating or surface treatment that causes a
`
`portion of the light to be emitted.” (Ex. 1001 at 4:36-40). This is the definition I shall
`
`apply when analyzing this element.
`
`III. ANALYSIS AND OPINION ON ISSUES OF INVALIDITY
`
`A.
`
`Summary
`
`35.
`
`In my opinion, claims 1, 3, 4, 5, 7, 8, 9 and 13 of the ’974 patent are
`
`either anticipated or obvious in light of prior art.
`
`36.
`
`I understand that a patent claim is anticipated under 35 U.S.C. § 102
`
`when a single piece of prior art describes every element of the claimed invention,
`
`either expressly or inherently, arranged in the same way as in the claim.
`
`37.
`
`I understand that a patent claim is obvious under 35 U.S.C. § 103 if the
`
`subject matter of the claim as a whole would have been obvious to a person of
`
`ordinary skill in the art as of the date of the invention.
`
`I understand that, unlike
`
`anticipation, obviousness may be shown by considering more than one prior art
`
`reference in combination.
`
`I have been informed that objective indicia of non-
`
`obviousness, sometimes referred to as “secondary considerations,” should be
`
`considered when assessing obviousness, including: (1) commercial success; (2) long
`
`
`
`felt but unresolved needs; (3) copying of the invention by others in the field; (4) initial
`
`expressions of disbelief by experts in the field; (5) failure of others to solve the
`
`problem that the inventor solved; and (6) unexpected results.
`
`Ground 1: Anticipation by Niizuma
`
`In my opinion, Niizuma anticipates claims 7, 8, 9 and 13 of the ’974
`
`B.
`
`38.
`
`patent.
`
`39.
`
`Niizuma, a publishedjapanese Patent Application JP H5—45651(U) is
`
`entitled “Liquid Crystal Display Device.” Niizuma was published on June 18, 1993.
`
`Niizuma names Fumiyasu Niizuma as it sole inventor.
`
`40.
`
`Niizuma discloses a means for producing a light emitting display
`
`assembly that is capable of providing sufficient illumination to serve as the backlight
`
`to a LCD assembly.
`
`(Ex. 1002 1] 5.) Niizuma further discloses an assembly that is
`
`comprised of multiple light sources in order to provide greater luminosity and better
`
`spatial homogenization of light across a larger LCD surface area.
`
`1. Niizuma anticipates claim 7
`
`41.
`
`In my opinion, the teachings of Niizuma disclose each and every
`
`element of claim 7 of the ’974 patent and thus claim 7 of the ’974 patent is anticipated
`
`under 35 U.S.C. § 102.
`
`42.
`
`The preamble of claim 7 requires a “light emitting panel assembly.” In
`
`anticipation of this element, Niizuma discloses a liquid crystal display device in Fig. 1
`
`(below) (Ex. 1002 1] 1). Niizuma notes that this liquid crystal display device is used
`
`Page 16 of61
`
`
`
`“in all types of electronic equipment, and is particularly related to the illumination
`
`structure with liquid crystal display devices.”
`
`1002 1] 1.)
`
`[Damn I)
`
`
`
`43.
`
`The second element of claim 7 requires the assembly include “a light
`
`emitting panel member having a light entrance surface and a light emitting surface.”
`
`Fig. 1 of Niizuma (reproduced above) discloses this element by depicting a light
`
`conductor (4). Light from the light source enters and “is guided into the light
`
`conductor (4) from the grooves (421, 421) at both ends of the light conductor (4)” and is
`
`“reflected out towards the LCD (1)” from the top surface of light conductor
`
`(Ex.
`
`1002 1] 19.) Grooves (421, 4a) are light entrance edges and the top surface of the light
`
`conductor (4) represents a light emitting surface. These features are all depicted in
`
`Fig. 3 below.
`
`
`
`[Drawing 3]

`
`
`

`
`I‘
`ii
`
`.
`
`44.
`
`The third element of claim 7 requires “at least one LED light source
`
`positioned near or against the light entrance surface.” In anticipation of this element,
`
`Figs. 1 and 3 of Niizuma (above) disclose “multiple lamps (6, 6)
`
`comprising of, for
`
`example, LEDs” that are positioned near light guide 4 against grooves (4a, 4a). These
`
`LED light sources “are fixed in position so that the clearance interval between them is
`
`equal to that between the grooves (Sb, 5b,
`
`on the holder (5) and the grooves (4a,
`
`4a,
`
`on the light conductor (4).” (Ex. 1002 1] 14.)
`
`45.
`
`Element four of claim 7 requires “a tray or housing having a cavity or
`
`recess in which the panel member is entirely received.” The housing described in
`
`Niizuma, comprising “frame 8” and “holder 5,” has a “recess (locking part) (5a)” in
`
`which “light conductor (4) is fixed in place by being inserted and locked into this
`
`recess (5a)” that satisfies this element of claim 7. (Ex. 1002
`
`12, 15, and 18, Figs. 1,
`
`3.) The highlighted version of Fig. 1 below illustrates this feature: light conductor (4),
`
`diffusing film (3), color filter (2), and LCD (1), highlighted in blue, are entirely
`
`received by frame (8) and holder (5), highlighted in yellow. Niizuma describes that
`
`the frame (8) is “fitted to the outer perimeter of the holder (5)” and thus they
`
`Page 18 of61
`
`
`
`1002 1[18.)
`
`46.
`
`Collectively, holder (5) and frame (8) receive and protect light conductor
`
`(4), diffusing film (3), color filter (2), and LCD (1): “once the frame (8) is attached, it
`
`is fine to push the front of the LCD (1) against the inside of front of the frame (8) so
`
`that the holder (5) and the LCD (1) etc. do not rattle.” (Ex. 1002 1] 18.) As further
`
`shown in highlighted Fig. 3 below,
`
`the housing, highlighted in yellow, forms a cavity
`
`in which the panel member, highlighted in green, is entirely received:
`
`
`
`
`
`47.
`
`Element five of claim 7 requires the light emitting panel have “a pattern
`
`of light extracting deformities on or in at least one surface to cause light to be emitted
`
`from the light emitting surface of the panel member.” Niizuma discloses that “finely
`
`serrated or ridged grooves cover the entirety of the back surface (4c) of the light
`
`conductor (4)” that cause light that enters light conductor (4) to “reflectfl out towards
`
`the LCD (1)” and thus anticipates this element.
`
`(Ex. 1002 1H] 11, 19, Fig. 3.) The
`
`finely serrated or ridged grooves constitute changes in the shape or geometry of light
`
`conductor (4)’s surface that causes a portion of the light to be emitted from light
`
`conductor (4).
`
`48.
`
`The sixth element of claim 7 requires that “the tray or housing includes
`
`end walls and side walls that act as end edge reflectors and side edge reflectors for the
`
`panel member to reflect light that would otherwise exit the panel member through an
`
`end edge and/or side edge back into the panel member and toward the pattern of
`
`light extracting deformities for causing additional light to be emitted from the light
`
`
`
`emitting surface of the panel member.” In anticipation of this element, Niizuma
`
`discloses that the walls of holder (5) are “formed from a white compound resin”
`
`which enables holder (5) “to reflect light leaked from the light conductor (4) to the
`
`holder (5) back into the light conductor (4), making it possible to reduce the
`
`attenuation of light emitted from the lamps (6, 6,
`
`and to efficiently illuminate the
`
`LCD (1).” (Ex. 1002 1]20.) The end walls and side walls described serve as end edge
`
`reflectors and side edge reflectors and thus reflect light back into the panel assembly
`
`to mitigate light loss and improve light efficiency. The re—directed light travels back
`
`towards the panel member towards the finely serrated or ridged grooves, which causes
`
`the light to be emitted from the top surface of light conductor (4).
`
`49.
`
`Element seven of claim 7 states that “the tray or housing has posts, tabs
`
`or other structural features that provide a mount or structural support for at least one
`
`other part or component.” Niizuma also anticipates this element of claim 7. Niizuma
`
`discloses a housing comprising frame (8) and holder (5) that is mounted to “printed
`
`circuit board (7) by the insertion of its latching pieces (8b, 8b,
`
`through the
`
`latching holes (7b, 7b,
`
`on the printed circuit board (7) and the bending of its
`
`latching pieces (8b, 8b,
`
`at the back of the printed circuit board (7).” (Ex. 1002 1]
`
`18.) The highlighted reproduction of Figure 1 below (where frame 8 and holder 5 are
`
`highlighted in yellow and printed circuit board 7 is highlighted in purple), depicts
`
`“multiple latching pieces (8b, 8b,
`
`that fit into the latching holes (7b, 7b,
`
`on the
`
`
`
`printed circuit board (7) described above, protrude from the perimeter of the back of
`
`the frame (8).”
`
`50.
`
`These latching piece (8b, 8b,
`
`constitute posts, tabs, or other
`
`structural features that provide a mount for mounting the housing, comprising frame
`
`8 and holder 5, and its encapsulated components to printed circuit board 7.
`
`51.
`
`The highlighted reproduction of Figure 3 below (where frame (8) and
`
`holder (5) are highlighted in yellow, light conductor (4) is highlighted in green, and
`
`LCD (1) is highlighted in brown), provides that “both end parts of the LCD (1) are
`
`locked by the extruding pieces (5f, 5f,
`
`of the holder (5), as shown in Figure 3, and
`
`its movement in the direction of both ends (to the left and right of the diagram) is
`
`controlled.”
`
`(Ex. 1002 1] 17.) The extruding pieces (locking parts) (Sf) cause the
`
`Page 22 of 61
`
`
`
`LCD (1), as well as light conductor (4), to be securely held in holder (5). Extruding
`
`pieces (locking parts) (5f) are posts, tabs, or other structural features that provide a
`
`mount or structural support for at least one other component, LCD (1).

`
`The eighth and final element of claim 7 requires that “the tray or
`
`housing provides structural support to the panel member.” Niizuma anticipates this
`
`element of the claim as well. Niizuma states that holder (5) is shaped to hold and lock
`
`light conductor (4) and LCD (1) in place:
`
`Furthermore, on the rear face 5b of holder 5 are formed a pair of
`inclined portions 5e, 5e that are bent towards the interior of holder 5
`and have a radius of curvature identical to that of the pair of inclined
`faces 4d, 4d of light guide 4, so that when light guide 4 is fitted into
`recess 53 ofholder 5, the rear face 4c of light guide 4 and the rear face
`5b of holder 5 become flush overall.
`
`53.
`
`(EX. 1002 1] 13.) In the highlighted version of Fig. 3 above (where
`
`frame (8) and holder (5) are highlighted in yellow and light conductor (4) is
`
`highlighted in green), holder (5) provides a pair of sloped structures (5e, 5e), that
`
`support light conductor
`
`The curvature angle of these sloped parts (Se, 5e) is the
`
`same as the curvature angle of sloped surfaces (4d, 4d) of light conductor (4), which
`
`
`
`enables holder (5) to support light guide (4) directly without any intermediary
`
`structure.
`
`(Id.)
`
`54.
`
`The highlighted reproduction of Figure 3 above also shows extruding
`
`pieces (locking parts) (5f) which are in place to provide structural support to light
`
`conductor (4), preventing its dislocation from the liquid crystal display device. These
`
`extruding pieces (locking parts) (Sf) help hold light conductor (4) and LCD (1) into
`
`place and thus serve to “ensur[e] that there will be no change in the relative positions
`
`of both ends of the LCD (1) and the light conductor
`
`.
`
`. even when subjected to
`
`external shocks.”
`
`(Ex. 1002 1] 17.)
`
`55.
`
`Also of note, frame (8) “fit[s] to the outer perimeter of the holder (5),”
`
`and uses an “opening (8a) somewhat smaller than the abovementioned LCD (1) is
`
`formed on its front.” This feature helps to ensure that light conductor (4) (as well as
`
`diffusing film (3), color filter (2), and LCD (1)) is supported by the housing and does
`
`“not rattle.” (Ex. 1002
`
`15 and 18) Based on the foregoing, Niizuma discloses that
`
`its housing, holder (5) and tray (8), provides structural support to the panel member,
`
`light conductor
`
`56.
`
`Considering the above, Niizuma discloses all limitations of claim 7.
`
`2. Niizuma anticipates claim 8
`
`57.
`
`In my opinion, Niizuma discloses each and every element of claim 8 of
`
`the ’974 patent and therefore anticipates claim 8 under 35 U.S.C. § 102.
`
`Page 24 of 61
`
`
`
`58.
`
`Claim 8 depends from claim 7 and further requires that the tray or
`
`housing have structural features that provide a mount or structural support for “a
`
`liquid crystal display.” As explained above,, the extruding pieces (locking parts) (Sf)
`
`serve as posts, tabs, or other structural features that provide a mount or structural
`
`support for LCD (1). Figure 3 above demonstrates how the extruding pieces (locking
`
`parts) (Sf) lock LCD (1) into place above light conductor (4). Niizuma thus discloses
`
`a housing with structural features that mount and provide structural support to a
`
`liquid crystal display.
`
`59.
`
`Considering the above, Niizuma discloses all limitations of claim 8.
`
`3. Niizuma anticipates claim 9
`
`60.
`
`In my opinion, Niizuma discloses each and every element of claim 9 of
`
`the ’974 patent and therefore anticipates claim 9 under 35 U.S.C. § 102.
`
`61.
`
`Claim 9 depends from claim 7 and further requires that the tray or
`
`housing have structural features that provide a mount or structural support for “a
`
`printed circuit.” As explain
