`
`II.
`
`QUALIFICATIONS
`
`5.
`
`My curriculum vitae is Ex. 2006. My experience in the display field
`
`dates back to the late l980’s when I worked as the lighting specialist in the Flight
`
`Deck Packaging group at Honeywell’s Commercial Air Transport Division.
`
`Initially my work focused on development of early technology liquid crystal
`
`display (LCD) components for flight control panels on commercial aircraft. I later
`
`participated in the technology development and productization of the active matrix
`
`LCD panels for the Boeing 777 program. In the early phases of this program we
`
`performed trade studies aimed at assessing the appropriate technology for
`
`replacing cathode ray tube (CRT) instruments on the flight deck. Technologies
`
`that I evaluated include rear projection micro-display LCD panels and thin—film
`
`transistor (TFT) LCDs. Following my work at Honeywell, I moved to Three-Five
`
`Systems where I worked again as a technical specialist for displays and lighting.
`
`While there, I interfaced with the liquid crystal on silicon (LCOS) projection team
`
`(later to become Brillian Corp.) on light engine design (light sources, thermal
`
`control) and reflective LCOS optical evaluation (radiometric characterization).
`
`While at Rosen Products I again worked as a senior technical specialist in displays
`
`where I was primarily focused on video system integration for automotive and
`
`4832-5056-2070.3
`
`

`
`aviation LCD display platforms. My work there included specifying and
`
`evaluating video controllers, source equipment, and displays for automotive rear
`
`seat entertainment and aircraft cabin entertainment systems.
`
`6.
`
`I am a named inventor on U.S. Patent No. 7,660,040 and European
`
`Patent No. l72462lAl, which are directed to a reflective material for LCD display
`
`backlighting. I also have a pending patent application (U.S. 13/564,045) for a
`
`“Dual Mode LCD Backlight” which employs a novel dichroic filtering design to
`
`create a single rail, night vision compatible backlight.
`
`7.
`
`I have a bachelor’s degree in Physics from the State University of
`
`New York at Plattsburgh and a bachelor of science degree in mechanical
`
`engineering from Arizona State University. I have additionally studied optics at
`
`the graduate level at the University of Oregon and have studied liquid crystal
`
`display technology at Kent State University (professional short courses).
`
`III.
`
`SCOPE OF ASSIGNMENT
`
`8.
`
`I have been retained to opine on the patentability of the claims in U.S.
`
`Patent No. 5,632,545 (“the ‘545 patent”), and on the claims proposed to be added
`
`to the ‘545 patent.
`
`9.
`
`I have been asked to consider whether Proposed Claims 4 and 5 of the
`
`‘545 patent are patentable over the prior art.
`
`4832-5056-2070. 3
`
`

`
`10.
`
`This declaration, including the exhibits hereto, sets forth my opinion
`
`on this topic.
`
`IV. LEGAL PRINCIPLES USED IN ANALYSIS
`
`11.
`
`I have been advised that, in construing a claim term, one looks
`
`primarily to the “intrinsic” patent evidence, which includes the words of the claims
`
`themselves, the remainder of the patent specification, and the prosecution history.
`
`I have been advised by patent owner’s counsel that “extrinsic” evidence, which is
`
`evidence external to the patent and the prosecution history, may also be useful in
`
`interpreting patent claims. Extrinsic evidence can include dictionaries, treatises,
`
`textbooks, and the like.
`
`12.
`
`In rendering the opinions set forth in this declaration, I was asked to
`
`consider the patent claims through the eyes of “one of ordinary skill in the art.” I
`
`was told by patent owner’s counsel to consider factors such as the educational level
`
`and years of experience of those working in the pertinent art; the types of problems
`
`encountered in the art; the teachings of the prior art; patents and publications of
`
`other persons or companies; and the sophistication of the technology. I understand
`
`that the person of ordinary skill in the art is not a specific real individual, but rather
`
`a hypothetical individual having the qualities reflected by the factors discussed
`
`above.
`
`4832-5056-2070.3
`
`

`
`13.
`
`In my opinion, based on my experience in research and product
`
`development of Video projection systems, and my evaluation of the skills and
`
`background that graduates of engineering programs should possess, a person of
`
`ordinary skill in the art of video projection systems is generally one who has a
`
`Bachelor’s degree in electrical engineering, optical engineering, and/or physics
`
`along with several years of relevant academic research or industry work experience
`
`in the field of video projection systems.
`
`V.
`
`CLAIM CONSTRUCTION OF THE CHALLENGED CLAIMS
`
`14.
`
`For the purposes of my opinion and declaration, I have reviewed the
`
`proposed claim constructions set forth on page 7 of Xilinx’s Opposition to Motion
`
`to Amend, Paper 26, (hereinafter “Opp.”).
`
`I disagree with several of the claim
`
`constructions proposed by Xilinx for the reasons discussed below.
`
`15.
`
`Page 7 of the Opp. attempts to define the claim phrase “fan in
`
`communication with an outside environment” to be a fan that circulates a fluid
`
`“between two separate spaces.” However, the plain language used in the claim
`
`requires “communication with an outside environment.” Xi1inx’s proposed
`
`definition ignores the term “outside” and reads it out of the claim phrase. Based on
`
`the disclosure set forth in the ‘545 patent, one of ordinary skill in the art would
`
`interpret the phrase “fan in communication with an outside environment” as a fan
`
`4832-5056-2070.3
`
`

`
`that transmits air from a projector system to an environment outside of the
`
`projector system.
`
`16. Xilinx construes the phrase “heat filter glass” as a “transparent
`
`material that blocks or absorbs ....” (Opp. at 7).
`
`I disagree with this proposed
`
`construction because it reads the term “glass” out of the term “heat filter glass.” I
`
`believe that the phrase “heat filter glass” should be construed as glass that filters
`
`heat by absorption or reflection of infrared radiation emitted by the projection
`
`lamps.
`
`17.
`
`I also disagree with Xilinx’s proposed construction of “second
`
`controller” in the phrase “second controller adapted to control the individual light
`
`sources and the fan.” On page 7 of the Opp., Xilinx asserts that the term “second
`
`controller” should be construed as “one or more control circuits separate from the
`
`video controller.” However, Xilinx provides no support for this overbroad
`
`construction and appears to have come up with the definition in an effort to bolster
`
`its arguments with respect
`
`to the Miyashita reference.
`
`Specifically, Xilinx
`
`provides no support for the assertion that the “second controller” should be
`
`construed as “one or more control circuits.” In addition, Xilinx has omitted the
`
`“adapted to” limitations from its construction of both the “second controller” and
`
`the “control link.” Based on the specification, the broadest reasonable construction
`
`to one of ordinary skill in the art of the phrase “second controller adapted to
`
`4832-5056-2070.3
`
`

`
`control the individual light sources and the fan” is a controller, other than the video
`
`controller, that controls a fan and individual light sources. The construction is
`
`supported by the specification of the ‘545 patent, which states that “[l]ight for the
`
`projector is generated in this embodiment by three High Intensity Discharge (HID)
`
`lamps 132-134, which are controlled by controller 130, which also controls a fan
`
`136 for cooling the light sources.” (Col. 2, lines 52-55). See also Fig.
`
`1 of the
`
`‘545 patent which illustrates “controller 130” as a single controller that is distinct
`
`from the video “controller 122.”
`
`VI. CHALLENGES #5 AND #6: ALLEGED OBVIOUSNESS OF
`
`PROPOSED CLAIMS 4 AND 5
`
`18.
`
`Both of Challenges #5 and #6 set forth in Xilinx’s Opposition rely on
`
`the combination of U.S. Patent No. 5,287,131 to Lee (hereinafter “Lee”) and U.S.
`
`Patent No. 5,313,234 to Miyashita (hereinafter “Miyashita”) as allegedly
`
`disclosing a “second controller adapted to control the individual light sources and
`
`the fan” and a “control link adapted to connect the video controller to the second
`
`controller,” as required by Proposed Claims 4 and 5. For the reasons discussed
`
`below, I disagree with Xilinx’s assertion that the combination of Miyashita and
`
`Lee renders the above-referenced claim elements obvious.
`
`19.
`
`Page 11 of the Opp. alleges that “Miyashita teaches a controller
`
`adapted to control a light source and a fan.” Xilinx relies upon col. 5, lines 21-41
`
`of Miyashita, Fig. 3 of Miyashita, and pages 25-26 of Dr. Buckman’s declaration
`
`4832-5056-2070.3
`
`8
`
`

`
`(Ex. 2012) as support for this assertion. (Opp. at 11). At col. 5, lines 21-41,
`
`Miyashita discloses:
`
`FIG. 3 is exemplary microprocessor-based
`
`implementation of LCVP 30. The functions of
`
`control unit 32 are all implemented by a
`
`microprocessor system. Several computer-
`
`implemented processes (programs) are used to
`
`replace the functional units described above. The
`
`important parts of each program are described
`
`below, in detail. The microprocessor system
`
`comprises a central processing unit (CPU) 90, a
`
`read only memory (ROM) 91, a random access
`
`memory (RAM) 92, a timer 94, and an
`
`input/output (I/O) port 93. ROM 91 stores the
`
`program for CPU 90 and RAM 92 stores
`
`temporary data and is used as a work space. Data
`
`from memory 80 is routinely read in by an
`
`initialization program and used to fill parts of
`
`RAM 92 (to improve access times later to such
`
`data). Digital interfaces are made via the I/O port
`
`93 to control input 60, display 62, an alarm 64,
`
`light detector 66, temperature detector, 68, main
`
`power controller 70, projection lamp power
`
`controller 72, signal source selector 74, fan motor
`
`controller 76, fan motor 78, memory 80, lens
`
`controller 82, and DAC 84.
`
`4832-5056-2070.3
`
`

`
`Thus, the relied upon portion of Miyashita lists a number of components of a
`
`“microprocessor system” and a number of controllers, including a “projection lamp
`
`power controller 72” and a “fan motor controller 76.” Fig. 3 of Miyashita, which
`
`is also relied upon by Xilinx and which is reproduced below, illustrates that the
`
`“projection lamp power controller 72” and “fan motor controller 76” are distinct
`
`components.
`
`
`
`5«<E
`
`..-.-........,

`
`The relied upon portions of Miyashita do not disclose a “second controller” that is

`
`

`
`Proposed Claims 4 and 5 (i.e., there is not a controller that controls BOTH the
`
`individual light sources and the fan). Rather, as illustrated in Fig. 3 above,
`
`Miyashita discloses a number of distinct slave controllers that form part of a
`
`microprocessor system, including a “projection lamp power controller 72” and a
`
`“fan motor controller 76.” The “projection lamp power controller 72” of Miyashita
`
`receives an input from the microprocessor control unit 32 and is used to control
`
`power to the projection lamp. For example, Miyashita teaches that “power to a
`
`projection lamp power supply 88 is controlled on/off by projection lamp power
`
`controller 72.” (C01. 6, lines 25-27). Miyashita does not disclose that the
`
`“projection lamp power controller 72” controls a fan in addition to controlling
`
`power to the projection lamp. In his declaration (Ex. 1012 at 29), Dr. Buckman
`
`annotated Fig. 3 of Miyashita by drawing a large box around numerous distinct
`
`elements and labeling the box as a second controller. Miyashita does not disclose
`
`that the elements included in Dr. Buckman’s box correspond to a controller.
`
`Rather, Miyashita merely lists the elements in Dr. Buckman’s box as distinct
`
`elements having distinct fiinctions. (See Miyashita, col. 5, lines 21-41). Dr.
`
`Buckman’s box, which is alleged to correspond to the claimed “second controller,”
`
`includes a “Fan Motor 78.” One of ordinary skill in the art would understand that a
`
`motor for a fan is not a component that is found in a “controller” and that Dr.
`
`Buckman’s box does not correspond to a controller. Similarly, one of ordinary
`
`4832-5056-2070.3
`
`1 1
`
`

`
`skill in the art would understand that a “Light Detector 66,” a “Projection Lamp
`
`Power Supply 88,” a “Main Power Supply 86,” a “Temperature Detector 68,” a
`
`“Display Apparatus 62,” and an “Alarm 64” are not components found in a
`
`controller. 1\/Iiyashita does not disclose a “second controller adapted to control the
`
`individual light sources 1 the fan,” as claimed. (Emphasis added). Lee also
`
`fails to disclose or suggest any controller that is “adapted to control the individual
`
`light sources 1131 the fan,” as claimed. (Emphasis added). Indeed, Xilinx does
`
`not assert that Lee teaches a controller that is “adapted to control the individual
`
`light sources and the fan,” as claimed. (Emphasis added). However, Xilinx does
`
`include the following language on page 5 of its Opposition:
`
`First, when “second controller” and “control link”
`
`are interpreted under the broadest reasonable
`
`construction, Lee does in fact teach these
`
`limitations. (XLNX-1004 at 3: 14-19; XLNX-
`
`1012 at 29-30.) In fact, Patent 0wner’s expert,
`
`Mr. Smith-Gillespie, even agrees that Lee
`
`teaches these limitations. (See Deposition of Mr.
`
`Smith-Gillespie, XLNX-1014 atl 5 7-5 8.)
`
`(Emphasis added). I strongly disagree with the allegation that I “agree[] that Lee
`
`teaches” the claimed “second controller” and “control link.” At no time during my
`
`deposition did I make such a statement. Rather, in response to the question “[s]o
`
`does the Lee reference have a second controller adapted to control the individual
`
`4832-5056-2070.3
`
`1 2
`
`

`
`light sources?”, I responded “Yes. It is item 18, a lamp controlling circuit, lamp
`
`voltage controlling circuit.” (Ex. 1014 at 157-5 8). Also, in response to the
`
`question “does controller 18 provide individualized variable control of each of the
`
`individual light sources?”, I responded “Yes. It shows that it does.” (Ex. 1014 at
`
`158). However, at no time did I state that Lee discloses a “second controller
`
`adapted to control the individual light sources and thefan,” as claimed.
`
`(Emphasis added). Also, at no time did I state that Lee discloses a “control link
`
`adapted to connect the video controller to the second controller,” as claimed. Lee
`
`does not teach such elements. Flasck, Rodriguez, and Edmonson also fail to
`
`disclose or suggest such elements.
`
`20. With respect to the claimed “control link adapted to connect the video
`
`controller to the second controller,” pages 11-12 of the Opposition state:
`
`Miyashita teaches a control link adapted to connect
`
`a video controller to a second controller. (XLNX—
`
`1012 at 27-28.) The video controller in Miyashita
`
`is implemented as a microprocessor system that
`
`uses a data bus to connect the microprocessor
`
`system to additional controller circuits. (Id.) The
`
`additional controller circuits include controls for a
`
`lamp and a fan. (Id.)
`
`4832-5056-2070.3
`
`1 3
`
`

`
`In his declaration, Dr. Buckman asserts that block 32 from Fig. 3 of Miyashita is a
`
`video controller. I disagree that element 32 in Miyashita is a video controller.
`
`With reference to Fig. 2, Miyashita describes element 32 as “a control unit 32
`
`having a control input interface 34, an instruction decoder 36, a power controller
`
`38, a signal source controller 40, a picture controller 42, an audio controller 44, a
`
`lens control interface 46, a fan motor control interface 48, a display controller 50, a
`
`light detector interface 52, a temperature detector interface 54, an alarm controller
`
`56, and a timer 58.” (C01. 4, lines 14-20). With reference to Fig. 3, Miyashita
`
`discloses that “[t]he functions of control unit 32 are all implemented by a
`
`microprocessor system.” (Col. 5, lines 22-23). One of ordinary skill in the art
`
`would not consider Miyashita’s “control unit 32” to be a Video controller. The
`
`control unit in Miyashita does not receive or process a video signal to facilitate the
`
`display of Video, which is what a Video controller does. Rather, the “control unit
`
`32” in Miyashita is a non-Video control unit that controls system power and system
`
`settings based on user input, feedback from sensors and detectors, and setting of an
`
`alarm when certain operation limits are exceeded (i.e., an over-temperature
`
`condition). Miyashita never refers to element 32 as a video controller, and fails to
`
`describe how its Video controller is implemented and fails to include its video
`
`controller in the figures. Indeed, Miyashita does not include the term “video
`
`4832-5056-2070.3
`
`14
`
`

`
`controller” and Dr. Buckman does not provide any support for his assertion that
`
`block 32 of Miyashita is a video controller.
`
`The Opposition does not point to any element or disclosure in Miyashita which is
`
`alleged to correspond to the claimed “control link.” Rather, the Opposition only
`
`relies upon Dr. Buckman’s declaration, Ex. 1012. On page 31 of his declaration,
`
`Dr. Buckman has annotated Fig. 3 of Miyashita to assert that the “I/O port 93” of
`
`Miyashita corresponds to the claimed “control link.” With respect to the I/O port
`
`93, Miyashita discloses that “[d]igital interfaces are made via the I/O port 93 to
`
`control input 60, display 62, an alarm 64, light detector 66, temperature detector,
`
`68, main power controller 70, projection lamp power controller 72, signal source
`
`selector 74, fan motor controller 76, fan motor 78, memory 80, lens controller 82,
`
`and DAC 84.” (C01. 5, lines 36-41). However, Claims 4 and 5 require “a control
`
`link adapted to connect the video controller to the second controller to provide
`
`individualized variable control of each of the individual light sources.” As
`
`discussed above, Miyashita fails to disclose a “second controller,” as claimed. It
`
`follows that Miyashita cannot disclose a “control link adapted to connect the video
`
`controller” to such a “second controller.” As also discussed above, element 32 of
`
`Miyashita is not a “video controller.” Thus, even if element 93 of Miyashita were
`
`a “control link ... to provide individualized variable control of each of the
`
`48326056-2070.3
`
`1 5
`
`

`
`individual light sources” (as discussed below, it is not), element 93 does not
`
`connect a “video controller to the second controller,” as claimed.
`
`21.
`
`Claims 4 and 5 require “a control link adapted to connect the video
`
`controller to the second controller to provide individualized variable control of
`
`each ofthe individual light sources.” (Emphasis added). Xilinx relies upon Lee
`
`as allegedly disclosing “individualized variable control of each of the individual
`
`light sources.” (Opp. at 12). Specifically, the Opposition alleges that “Lee teaches
`
`a control link that connects a controller to three individual light sources” and that
`
`this alleged “control link” “provides individualized variable control of each of
`
`individual light sources.” (Opp. at 12). However, the claimed “control link” of
`
`Proposed Claims 4 and 5 is “adapted to connect the video controller to the second
`
`controller,” not the second controller to the light sources. In addition, Claims 4
`
`and 5 explicitly recite that the “control link” is utilized “to provide individualized
`
`variable control of each of the individual light sources.” Lee and Miyashita fail to
`
`disclose such a “control link” that (i) connects the video controller to the second
`
`controller, and (ii) provides individual variable control of each of the individual
`
`light sources. Xilinx appears to be trying to dissect the claim language in an effort
`
`to allege that Miyashita discloses the “control link” and Lee discloses
`
`“individualized variable control.” However, such dissection of the claim elements
`
`is improper. One of ordinary skill in the art would understand that the claimed
`
`4832-5056-2070.3
`
`1 6
`
`

`
`“control link” is not merely a “link,” but rather a “control link” through which
`
`some control is implemented. This implemented control that is provided through
`
`the “control link” is explicitly identified in the claims as “individualized variable
`
`control of each of the individual light sources.” It is also important to note that the
`
`“control link” is a connection between the “video controller” and the “second
`
`controller.” Based on this connection and the disclosure of the ‘545 patent, one of
`
`ordinary skill in the art would understand that the “individualized variable control”
`
`implemented Via the “control link” is a direct result of the connection between the
`
`“Video controller” and the “second controller” and that the “individualized Variable
`
`control” occurs as a result of information in a Video signal that is received by the
`
`video controller. Thus, it is improper to dissect the claim as proposed by Xilinx
`
`because the claims clearly require “a control link adapted to connect the video
`
`controller to the second controller to provide individualized variable control of
`
`each ofthe individual light sources.” Alone or in combination, Lee and Miyashita
`
`fail to disclose any such element that “connect[s] the video controller to the second
`
`controller to provide individualized variable control of each of the individual light
`
`sources,” as claimed. Flasck, Rodriguez, and Edmonson also fail to disclose or
`
`suggest such elements.
`
`22. Xilinx has relied upon Rodriguez and Edmonson as allegedly
`
`disclosing the claimed “heat containment system.” However, one of ordinary skill
`
`4832-5056-2070.3
`
`1 7
`
`

`
`in the art would not be motivated to combine Rodriguez or Edmonson with Lee as
`
`proposed by Xilinx. In its system, Lee eliminates the need for a cooling device
`
`and expressly teaches that “a cooling device for cooling the LC panel is not
`
`necessary any more.” (Col. 3:67 — col. 4:7; emphasis added). Thus, Lee teaches
`
`away from Xilinx’s proposed combination of Rodriguez’s alleged heat
`
`containment system with Lee because Rodriguez’s alleged heat containment
`
`includes a “cooling device” (i.e., fan 72) to cool the system. The same is true with
`
`respect to the proposed combination of Edmonson with Lee because Edmonson’s
`
`alleged heat containment system includes a fan 140.

`VII. CONCLUSION
`
`23.
`
`In my opinion, Proposed Claims 4 and 5 of the ‘545 patent are
`
`patentable in view of Flasck, Lee, Rodriguez, Edmonson, and Miyashita because
`
`the combination fails to disclose or suggest one or more elements required by
`
`Claims 4 and 5.
`

`
`I declare under penalty of perjury that the foregoing is true and
`
`correct. Executed this 15th day of October, 2013.
