`
`INTRODUCTION
`
`I prepared this Declaration at the request of Vilox Technologies, LLC stating
`
`
`I.
`
`1.
`
`my opinions as an independent expert regarding issues raised in the matter of
`
`Petition IPR2018-00044 (“Petition”), the April 19, 2018 Decision on Institution of
`
`Inter Partes Review (“Decision”), Petitioner’s Reply to Patent Owner’s Response
`
`(“Petitioner’s Reply”), and Petitioner’s Opposition to Patent Owner’s Motion to
`
`Amend (“Opposition”).
`
`2.
`
`In preparation for this Declaration, I also studied Exhibit 1013, Declaration of
`
`Dr. Philip Greenspun (Greenspun-MtA), Exhibit 1014, U.S. Patent 6,452,597 to
`
`Goldberg (Goldberg), Petitioner’s Opposition (Opposition), and Petitioner’s Reply
`
`(Petitioner’s Reply). I also reviewed Exhibits 1001 – 1010 provided by Petitioner
`
`as well as Exhibit 2021, Declaration of Dr. Joseph L. De Bellis, Exhibit 2022 and
`
`2029; Declarations of Missy De Bellis; Exhibit 2025, Figure 10 of the ‘423 Patent;
`
`Exhibit 2015, Deposition Transcript of Dr. Philip Greenspun; and all Exhibits and
`
`other documents referenced in Exhibit 2017, Declaration of Dr. Wesley W. Chu.
`
`3.
`
`In preparing this Declaration I also relied on my knowledge and experience
`
`gained through 56 years as an engineer, professor, and consultant.
`
`4.
`
`I am being compensated for this work, and my compensation is not dependent
`
`on the outcome of this matter.

`
`
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`II. QUALIFICATIONS AND PROFESSIONAL EXPERIENCE
`
`5. My experience is detailed in my previous Declaration, Exhibit 2021. My
`
`Curriculum Vitae is provided as Exhibit 2002.
`
`III. OPPOSITION TO MOTION TO AMEND
`
`6.
`
`The Opposition states that the ‘423 Patent does not provide written description
`
`support for the proposed amended claim 24 limitation (limitation [24.5])“displaying
`
`a truncated portion of each entry in the selected database field.” The Opposition
`
`alleges that what is disclosed is “instead, a subset of the entries … and not each
`
`entry.” Opp., p. 1-2.
`
`7.
`
`The Opposition notes that “Patent Owner asserts limitation [24.5] is supported
`
`by the ‘423 patent from column 8, line 48 to column 9, 2, and at column 9 at lines
`
`20-24.” Opp., p. 2.
`
`8.
`
`The Opposition makes similar allegations with respect to proposed amended
`
`claim 25, specifically limitation [25.8]. Opp., pp. 5-6
`
`9.
`
`Proposed amended claims 24 and 25 are directed to truncating entries in
`
`search results, with the final, truncated list or display of entries including a portion
`
`of each truncated entry. The claims recite truncation limitations based on
`
`determining a number of characters in each original entry and then truncating the
`
`entry. The Opposition goes to great length to alleged that the cited portions of the
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 3 of 17
`
`
`
`
`‘423 Patent “do not provide the requisite written description support for the amended
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`limitation” of “displaying a truncated portion of each entry in the selected database
`
`field.” Opp., pp 2-3. The Opposition then cites a section of the disclosure that shows
`
`truncation of six city names to three entries. Opp., p 3. The Opposition concludes
`
`that truncating the six city names should produce six truncated entries, and that,
`
`accordingly, the “disclosure,” by showing only three entries, namely “Arm, New,
`
`Riv” fails to support the claim limitations. Opp., pp 3-4. But the Opposition goes
`
`on to acknowledge that the disclosure shows “truncation of entries to collapse the
`
`number of entries into a smaller or lower number, such that the smaller or lower
`
`number of entries can be displayed on a terminal screen” and that “the purpose of
`
`‘truncation’ in the ‘423 Patent is to reduce a number of lines in a result list so as to
`
`collapse the list vertically by reducing the number of characters in returned entries
`
`to common characters.” Opp., pp 4-5.
`
`10. A PHOSITA would understand that in proposed amended claims 24 and 25,
`
`the claimed truncation reduces characters and will result in collapsing the result list
`
`vertically so that the result list may be displayed on the terminal. Thus, the cities
`
`Armandia and Armonk, in the disclosed example, become “Arm,” thereby reducing
`
`the number of lines by one. However, “a truncated portion [in the example, “Arm”]
`
`of each entry in the selected database field is displayed,” as recited in proposed
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 4 of 17
`
`
`
`
`amended claims 24 and 25. Nowhere do the proposed amended claims 24 and 25
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`recite that each entry, once truncated, must be displayed, as the Petitioner apparently
`
`assumes. That is, as a PHOSITA would understand, neither proposed amended
`
`claim 24 nor 25 recites or requires “displaying each truncated entry.” Doing so
`
`would be contrary to the disclosure of the ‘423 Patent, as Petitioner acknowledges.
`
`Opp., pp. 2-3. The claim limitation of “a truncated portion of each entry in the
`
`selected database field is displayed” is clearly supported in the section of the
`
`disclosure cited in the Opposition. Thus, a PHOSITA, viewing the disclosure and
`
`each of proposed amended claims 24 and 25, would understand that truncation of
`
`Armandia and Armonk to three characters and displaying “Arm” on the terminal
`
`meets the limitation of “a truncated portion of each entry in the selected database
`
`field is displayed” – “Arm” being a truncated portion of Armandia and Armonk.
`
`11. Proposed amended claims 26 and 27 add to their base claim 25 the limitations
`
`“all entries from the selected data field are displayed on a single page of a terminal.”
`
`Claims 26 and 27 also recite “the specified limit is determined dynamically, based
`
`on a characteristic of the terminal.” However, this limitation was already present in
`
`claim 6, the original claim from which claims 26 and 27 are derived. In attacking
`
`proposed amended claims 26 and 27 for alleged lack of support, the Opposition
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 5 of 17
`
`
`
`
`merely refers to its arguments related to the allegedly lacking disclosure in support
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`of proposed amended claims 24 and 25.
`
`12. A PHOSITA would understand that the operation of claim 25 generates a
`
`result list having truncated entries. The example cited in the Opposition is a result
`
`list having three entries “Arm, New, Riv.” Claims 26 and 27 merely recite that the
`
`entries are displayed on a single page of a terminal. The Opposition asserts that
`
`“[t]he identified portion of the ‘423 Patent, column 8 line 40 to 52, does not provide
`
`written description support for determining a limit dynamically’.” Opp., pp 7-8. The
`
`cited disclosure states “if the size of the resulting result list is larger than some
`
`numeric parameter related to the display size of the terminal 14, then the constrains
`
`may be modified by the truncator 152 so that the result list can be accommodated
`
`(e.g., displayed on one page) by the terminal 14.” Ex 1001, 8:44-48. Thus, this first
`
`challenged limitation of claims 26 and 27 is fully supported in the original
`
`disclosure. A PHOSITA would have understood that “dynamically determined,” as
`
`recited in proposed amended claims 26 and 27, in the context of computer, refers to
`
`“an event or process that occurs during computer program execution.” The
`
`PHOSITA would have understood the above quoted excerpt from the ‘423 Patent
`
`refers to a process (truncation) that occurs during execution of truncator 152, which,
`
`a PHOSITA would have known, was a computer program. See Ex. 2028, an excerpt
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 6 of 17
`
`
`
`
`from IEEE Standard Dictionary of Electrical and Electronic Terms, 1996 ed.
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`(defining “dynamically”).
`
`13. Exhibit 1013, Declaration of Dr. Philip Greenspun (“Greenspun MtA”),
`
`asserts that certain limitations of proposed claims 26 and 27 “would be taught by
`
`Maloney, Bertram, and Kanevsky or Excel, Bertram, and Kanevsky; Greenspun MtA
`
`asserts if the underlying database were small in size.” Greenspun MtA, ¶ 13.
`
`14.
`
`In my opinion, a PHOSITA would find this statement by Petitioner’s expert
`
`to be unsupportable and contrary to how the PHOSITA would view the combination
`
`of references.
`
`15. Specifically, Petitioner’s expert states that “at least some tables would not
`
`contain enough data for a multiple screen display to be necessary in the first
`
`instance.” Greenspun MtA, ¶ 13. Yet Petitioner’s expert does not quantify what he
`
`means by “small in size” and a PHOSITA would be left to wonder just what the
`
`definition of “small in size” is. A PHOSITA might understand a small database
`
`could have perhaps a hundred entries. The PHOSITA would know that a hundred
`
`entries may be too large to fit on certain displays. Furthermore, the PHOSITA would
`
`know that the ability to fit data onto a single page of a terminal depends on not just
`
`the number of entries, but also on the quantity of data in each entry. A PHOSITA
`
`would find arguments of Petitioner’s expert related to “databases [that are] small in
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 7 of 17
`
`
`
`
`size” to be vague and technically incorrect. In short, Petitioner’s expert proposes a
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`hypothetical without bounds.
`
`16. Greenspun MtA then states that Goldberg “explicitly teaches this limitation.”
`
`Greenspun MtA, ¶ 14. A PHOSITA would understand that Goldberg neither teaches
`
`nor suggests this limitation.
`
`17. Goldberg is directed to a system that displays information to a user (i.e., a
`
`driver) operating a motor vehicle. An example of such information is an address to
`
`which the driver is proceeding; the address is presented on an in-vehicle display.
`
`Goldberg discloses that such information “[t]o be useful … should be easily readable
`
`by the user. This is particularly true in a vehicle computer because the user (e.g., the
`
`driver of the vehicle) may only be able to take brief glances at the display.” Ex.
`
`1014, 1:29-33. Goldberg then explicitly discloses that its system is intended to
`
`“automatically adjust the size of information being displayed … in order to make
`
`the information easily readable while at the same time leaving most (or all) of the
`
`information displayed on a single screen.” Ex. 1014, 2:4-9.
`
`18. The Opposition notes that Goldberg discloses fitting other applications such
`
`as spreadsheet applications to small screens. Opp., p. 15. However, because
`
`Goldberg does not describe such a process as displaying a spreadsheet on a small
`
`screen, the Opposition provides no citation to Goldberg that would lead a PHOSITA
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 8 of 17
`
`
`
`
`to understand how such a process could occur. Faced with just a bares statement
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`that its concepts could be used “for spreadsheet applications,” (Ex. 1014, 4:22-25),
`
`a PHOSITA would not know how such a spreadsheet application could be
`
`“miniaturized” to fit Goldberg’s display and still be “readable” to any occupant of
`
`the vehicle (or any user of a small-scale display).
`
`19. The passages from Goldberg that I cite in paragraphs 17 and 18 above would
`
`lead a PHOSITA to understand that Goldberg’s preeminent concept is to make a
`
`sufficient amount of data available on a single screen, if possible, and to make that
`
`data “readable” in the sense that the characters are sufficiently large, and the text
`
`sufficiently complete, in the sense that the driver would know precisely and with no
`
`ambiguity, what information (for example, a street address) is being conveyed, and
`
`to do so in a manner that would not distract the driver from his most important task,
`
`namely safely operating the vehicle.
`
`20. Thus, a PHOSITA would know that Goldberg teaches retention of a sufficient
`
`amount of information on the computer display. A PHOSITA would further know
`
`that were the information to be displayed reduced for display on a single screen,
`
`through some process such as truncation, to the point that the intended information
`
`became ambiguous, the information would instead be displayed on multiple screens.
`
`In other words, a PHOSITA would know there is some limit to the reduction of
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 9 of 17
`
`
`
`
`information to make it fit on a single display, rather than the unbound hypothetical
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`proposed by Petitioner’s expert.
`
`21. A PHOSITA further would know that Goldberg is directed to display of one,
`
`and only one, “entry” on the screen, or within a button on the screen (a “button”
`
`being a screen within a screen – see Ex. 1014, 6:36-47 (noting that a “button” is a
`
`display area)). The example information items provided in Goldberg all are street
`
`addresses (Figures 5a – 5f) or data related to operation of the vehicle (Figure 5g),
`
`data that readily may be expressed in the form of a single entry displayable on a
`
`single page or screen of the display area (as opposed to spreadsheet and word
`
`processing documents, which a PHOSITA would understand would require multiple
`
`pages or screens for display).
`
`22.
`
`In contrast to Goldberg, proposed amended claims 26 and 27 recite “wherein
`
`each entry from the selected data field is displayed on a single page of the terminal,
`
`and wherein the specified limit is determined dynamically, based on a characteristic
`
`of the terminal.” Claims 26 and 27, depending on proposed amended claim 25, and
`
`thereby incorporating all its respective limitations, must be construed to mean that
`
`each of a plurality of entries is displayed on a single page of a terminal.
`
`23. Petitioner’s expert argues that Goldberg discloses displaying “all entries from
`
`the selected data field … on a single page of a terminal.” Greenspun MtA ¶ 14. No
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 10 of 17
`
`
`
`
`PHOSITA would understand Goldberg provides this teaching. First, Petitioner’s
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`expert states that “Goldberg teaches that, when a given set of data or information is
`
`to be displayed on a screen … adjusting the data to be displayed … .” Greenspun
`
`MtA ¶ 20 (emphasis added). However, a PHOSITA would understand that nothing
`
`in Goldberg discloses or suggests applying its methods to a “set of data,” and
`
`Petitioner’s expert fails to cite any disclosure in Goldberg to support this statement.
`
`Rather, a PHOSITA would understand that Goldberg is directed to adjusting the size
`
`of information contained in a single entry, such as a street address where the driver
`
`“is supposed to be going to.” Ex. 1014, 1:63; Figs. 5a – 5g. Even were Goldberg to
`
`be read to apply to a “plurality of entries” (which no PHOSITA would understand
`
`from studying Goldberg), a PHOSITA would understand that because Goldberg’s
`
`system is directed to making data “readable” to a vehicle operator (driver), Goldberg
`
`simply would display each of the entries (adjusted in size or not adjusted) on a
`
`separate screen or page so that the driver could readily read (and grasp) the data
`
`using only brief glances at the computer screen to avoid distraction from safe
`
`operation of the vehicle. In summary, a PHOSITA would not understand that
`
`Goldberg provides a teaching or suggestion to display “each of a plurality of entries
`
`on a single page of the terminal.” Thus, it appears Petitioner is trying to stretch
`
`Goldberg’s disclosure to apply it to proposed amended claims 26 and 27.
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 11 of 17
`
`
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`In addition to no teaching or even suggesting of the claim limitations of
`
`
`24.
`
`proposed amended claims 26 and 27, a PHOSITA would not be motivated to
`
`combine Goldberg with Maloney, Bertram, and Kanevsky or to combine Goldberg
`
`with Excel, Bertram, and Kanevsky. This lack of motivation is based on Goldberg’s
`
`express teaching away from the limitations of proposed amended claims 26 and 27.
`
`Specifically, Goldberg explicitly states that “adding lines” to a text entry is an
`
`important option to make an entry readable for an vehicle operator so as to avoid
`
`distracting the driver, who can only briefly view the display. Ex. 1014, 1:46-52. As
`
`Petitioner acknowledges, the challenged claims in this IPR, and by extension, the
`
`proposed claims, are directed to compressing the vertical space required for display
`
`of multiple entries. Opp., pp. 2-3. Adding lines to be displayed is directly contrary
`
`to reducing the number of lines to be displayed. Accordingly, a PHOSITA would
`
`not be motivated to incorporate Goldberg’s teachings of adding lines to improve
`
`readability because to do so would have an effect that is unwanted and diametrically
`
`opposite to the intended reduction of vertical lines the proposed amended claims 24
`
`– 27 encompass in order to make the entries fit the available display space. Petitioner
`
`argues that it is citing Goldberg for its alleged teaching of fitting an entry to a small
`
`display, one option for which is to truncate a “caption,” which as Goldberg discloses,
`
`does not affect the informative value of the entry to be “adjusted.” Ex. 1014, 4:35-
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 12 of 17
`
`
`
`
`45. However, this argument ignores Goldberg’s clear disclosure to add lines, which
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`Petitioner clearly ignores; that is, Petitioner cites only so much of Goldberg as
`
`Petitioner finds helpful while ignoring portions of Goldberg that are harmful to
`
`Petitioner’s position and argument.
`
`IV. PETITIONER’S REPLY TO PATENT OWNER’S RESPONSE TO
`
`PETITIONER’S PETITION
`
`25.
`
`In its Reply to Patent Owner’s Response, Petitioner states “Vilox does not
`
`allege conception of the claimed subject matter.” Petitioner’s Reply, page 1. More
`
`specifically, in the Petitioner’s Reply, Petitioner states Vilox fails to prove reduction
`
`to practice and that “Patent Owner must produce evidence showing the inventor …
`
`constructed an embodiment or performed a process that met all the claim
`
`limitations.” Petitioner’s Reply, page 10. However, the ‘423 Patent includes Figure
`
`10, which Patent Owner avers is a screen shot of a prototype search-on-the-fly
`
`system developed by Patent Owner and demonstrated to both Missy De Bellis and
`
`Patent Owner’s attorneys at least by December 9, 1999. Missy De Bellis testified to
`
`this fact in her July 9, 2018 Declaration:
`
`Submitted concurrently with my declaration as Exhibit 2025 is Figure
`
`10 to U.S. Patent 6,760,720. I recognize Figure 10 to be a reproduction
`
`of a screenshot of the search-on-the-fly system developed and
`
`
`
`IPR 2018-00044
`Exhibit 2027 / Page 13 of 17
`
`
`
`
`
`Case IPR2018-00044
`Patent No. 7,302,423
`Declaration of Wesley W. Chu, Ph.D.
`
`demonstrated by Dr. De Bellis and Mr. Freire. I recognize it because I
`
`specifically recall Mr. Freire importing data from the telephone book
`
`for purposes of demonstrating the search-on-the-fly software.
`
`Ex. 2022, ¶ 25.
`
`26. Furthermore, Dr. De Bellis testified in his July 9, 2018 Declaration (Exhibit
`
`2021) as follows:
`
`I explained to Ms. De Bellis that by using the system and methods
`
`described above, we would have much better visibility into the data for
`
`a given patient. In essence, she, as Office Manager, would be able to
`
`roll and tumble the data across our multiple databases, or search on the
`
`fly. Our software then would truncate search results, as necessary, so
`
`that she could view all search results on one page of the terminal, which
`
`would allow her to recognize the results.
`
`Ex. 2021, ¶ 11.
`
`27. A PHOSITA would understand that Figure 10 as described in the ‘423 Patent
`
`discloses each and every limitation of independent claims 1 and 3. Below is a chart
`
`comparing claim 1, as exemplary, to Figure 10 and its accompanying description:

`
`In summary, a PHOSITA would understand Patent Owner, by December 9,
`

`
`1999.
