`
`
`
`I, Scott Schaefer, declare as follows:
`
`I.
`
`INTRODUCTION
`
`1.
`
`I have personal knowledge of the facts and opinions set forth in this
`
`declaration, and if called upon to do so, I would testify competently thereto.
`
`2.
`
`I am over the age of eighteen (18) and competent to make this
`
`Declaration.
`
`3.
`
`I have been retained by Patent Owner SpaceTime 3D, Inc. to provide
`
`assistance, analysis, and opinions regarding IPR2023-00242 and U.S. Patent No.
`
`8,881,048 (“the ’048 patent”) as an expert in the field of computer science, and
`
`particularly in the area of 2D and 3D graphics and graphical user interfaces to
`
`evaluate the validity of the ’048 patent in light of the assertions made in Petitioners
`
`Apple Inc. and Google LLC’s (collectively, “Petitioner”) Petition for Inter Partes
`
`Review of U.S. Patent No. 8,881,048 (“Petition”) (See Paper 2).
`
`4.
`
`I understand that this declaration (“Supplemental Declaration”) will be
`
`submitted in support of Patent Owner’s Sur-Reply to Petitioner’s Reply to the
`
`Petition for inter partes review of the ’048 patent. This Supplemental Declaration
`
`addresses assertions made by Petitioner in the Reply and its expert in his
`
`supplemental declaration (EX1060). This Supplemental Declaration supplements
`
`certain portions of my prior declaration in support of the Patent Owner’s Response
`
`in this IPR Proceeding (EX2014, “my Prior Declaration”). In my Prior Declaration,
`
`SPACETIME3D
`EX2023 - PAGE 3
`
`
`
`I address many topics, including (but not limited to) my background and
`
`qualifications (see e.g., my CV at EX2014, Appendix A), my opinions, and their
`
`underlying bases, regarding the person of ordinary skill in the art at the time of the
`
`claimed inventions (“POSITA”); the fields of graphical user interfaces (“GUI”),
`
`including two dimensional (“2D”) and three dimensional (“3D”) spaces or
`
`environment; the ’048 patent; the construction of claim terms as understood by a
`
`POSITA; the prior art of record; and the validity of the ’048 patent, including a
`
`detailed analysis of the prior art cited by Petitioner, including why it does not render
`
`the ’048 patent obvious and why a POSITA would not have been motivated to make
`
`the prior art combinations asserted by Petitioner.
`
`5.
`
`I maintain all of my earlier analysis and continue to hold the opinions
`
`expressed in my Prior Declaration. This Supplemental Declaration does not replace
`
`my Prior Declaration. These declarations are complementary and should be read in
`
`tandem. Accordingly, this Supplemental Declaration does not cover every topic
`
`addressed in my Prior Declaration. In his supplemental declaration (EX1060), Dr.
`
`Fuchs makes numerous mischaracterizations of my positions and while I have
`
`addressed some of these below, the fact that I do not address every one of them
`
`should not be interpreted as my agreement with Dr. Fuchs’ mischaracterizations.
`
`Similarly, the fact that I did not address every point Dr. Fuchs asserted in his Prior
`
`SPACETIME3D
`EX2023 - PAGE 4
`
`
`
`Declaration or Supplemental Declaration should not be interpreted as my agreement
`
`with Dr. Fuchs on those points.
`
`6.
`
`In forming this Supplemental Declaration, I have considered the
`
`declarations of Petitioner’s expert Dr. Fuchs (EX1003 and EX1060), newly
`
`submitted Exhibits EX1055 and EX1056, the Board’s institution decision (Paper
`
`11), Petitioner’s reply (Paper 26), my knowledge and experience in this field,
`
`including my research and work experience in the field, my experience working with
`
`others involved in the field, and the third-party documents cited throughout my
`
`analysis .
`
`7.
`
`I am being compensated at my normal hourly rate for my time spent on
`
`this proceeding and for expenses incurred as a result of my role as an expert. My
`
`compensation is not in any way contingent on my performance, the result of this
`
`proceeding, or any of the issues involved therein. I have no financial interest in the
`
`outcome of this case.
`
`II. LEGAL PRINCIPLES REGARDING VALIDITY
`
`8.
`
`I am not an attorney. For purposes of this report, I have been informed
`
`by counsel of the following legal standards that apply to the issues I address in this
`
`report.
`
`SPACETIME3D
`EX2023 - PAGE 5
`
`
`
`A. Validity Generally
`
`9.
`
`I understand that in litigation district court judges must presume that
`
`the claims of an issued patent are presumed to be valid. The basis for the
`
`presumption of validity is the fact that the allowed claims went through a rigorous
`
`examination process at the U.S. Patent Office. In this proceeding, I have not applied
`
`an presumption of validity in my analysis of the instituted grounds in the petition.
`
`10.
`
`I understand that Petitioner has the burden of proving invalidity by a
`
`preponderance of the evidence, and that the burden of proof never shifts to the
`
`plaintiff to prove the validity of the ’048 patent.
`
`B.
`
`11.
`
`Priority Date
`
`I understand that an inventor establishes priority of an invention by
`
`conceiving of the invention and reducing the invention to practice.
`
`12.
`
`I understand that a patent application may establish priority of invention
`
`when it supports all elements of the asserted claims.
`
`C. Anticipation
`
`13.
`
`I understand from counsel for Patent Owner that invalidation by
`
`anticipation occurs only when a single alleged prior art reference discloses each and
`
`every limitation of the claim at issue, either expressly or inherently. In other words,
`
`every limitation of the claim must identically appear in a single prior art reference
`
`SPACETIME3D
`EX2023 - PAGE 6
`
`
`
`for the reference to anticipate that claim. I also understand that all elements of the
`
`claim must be disclosed in the reference as they are arranged in the claim.
`
`14.
`
`I understand that to be considered anticipatory, the prior art reference
`
`must be enabling and must describe the patentee’s claimed invention sufficiently to
`
`have placed it in possession of a person of ordinary skill in the field of the invention.
`
`15.
`
`I understand that the Petitioner did not assert, and the Board has not
`
`instituted, any grounds of unpatentability pursuant to Section 102.
`
`D. Obviousness
`
`16.
`
`It has further been explained to me by counsel for Patent Owner that a
`
`claim is obvious pursuant to 35 U.S.C. § 103 if the differences between the claimed
`
`invention and the prior art are such that the claimed invention as a whole would have
`
`been obvious before the effective filing date of the claimed invention to a person
`
`having ordinary skill in the art to which the claimed invention pertains. As such, I
`
`understand that a claim is valid unless the differences between the claimed invention
`
`and the prior art are such that the subject matter as a whole would have been obvious
`
`at the time the invention was made to a person having ordinary skill in the art to
`
`which the claimed invention pertains.
`
`17.
`
`It has further been explained to me by counsel for Patent Owner that
`
`the following factors are used to make an obviousness determination: (i) the scope
`
`and content of the prior art; (ii) the level of ordinary skill in the art; (iii) the
`
`SPACETIME3D
`EX2023 - PAGE 7
`
`
`
`differences between the claimed invention and the prior art; and (iv) objective or
`
`secondary considerations of nonobviousness. Any relevant objective factors or
`
`secondary considerations of non-obviousness, which may include commercial
`
`success of a product using the invention, if that commercial success is due to the
`
`invention; long-felt need for the invention; evidence of copying of the claimed
`
`invention; industry acceptance; the taking of licenses under the patent by others;
`
`initial skepticism; failure of others; and praise of the invention.
`
`18.
`
`I understand that when a patentee can demonstrate commercial success,
`
`usually shown by significant sales in a relevant market, and that the successful
`
`product is the invention disclosed and claimed in the patent, it is presumed that the
`
`commercial success is due to the patented invention. I also understand that courts
`
`may find the commercial success of the infringer and other members of the industry
`
`persuasive even though the patentee was not successful with a product covered by
`
`the patent.
`
`19.
`
`I understand that a patent claim composed of several elements is not
`
`proved obvious merely by demonstrating that each of its elements was independently
`
`known in the prior art. But multiple prior art references or elements may, in some
`
`circumstances, be combined to render a patent claim obvious. I understand that I
`
`should consider whether there is an “apparent reason” to combine the prior art
`
`references or elements in the way the patent claims. Requiring a reason for the prior
`
`SPACETIME3D
`EX2023 - PAGE 8
`
`
`
`art combination protects against the distortion caused by hindsight. Along the same
`
`lines, one cannot use the asserted patent as a blueprint to piece together the prior art
`
`in order to combine the right ones in the right way as to create the claimed inventions.
`
`To determine whether such an “apparent reason” exists to combine the prior art
`
`references or elements in the way a patent claims, it will often be necessary to look
`
`to the interrelated teachings of multiple patents, to the effects of demands known to
`
`the design community or present in the marketplace, and to the background
`
`knowledge possessed by a person having ordinary skill in the art.
`
`20.
`
`It has further been explained to me by counsel for Patent Owner that
`
`the motivation to combine must be more than mere conclusory statements and that
`
`a generic motivation to combine known elements is insufficient to establish
`
`obviousness. I understand that the motivation to combine prior art references must
`
`be identified in the Petition.
`
`21.
`
`I understand that when the prior art “teaches away” from combining
`
`prior art references or certain known elements, discovery of a successful means of
`
`combining them is less likely to be obvious. A prior art reference may be said to
`
`“teach away” from a patent when a person of ordinary skill, upon reading the
`
`reference, would be discouraged from following the path set out in the patent or
`
`would be led in a direction divergent from the path that was taken by the patent.
`
`SPACETIME3D
`EX2023 - PAGE 9
`
`
`
`22.
`
`I understand that in developing opinions as to whether or not certain
`
`claimed subject matter would have been obvious, each claim of a given patent should
`
`be considered in its entirety and separately from any other claims. In so doing, it is
`
`my further understanding that while I should consider any differences between the
`
`claimed invention and the prior art, I should also assess the obviousness or non-
`
`obviousness of the entirety of a claim covering an alleged invention, not merely
`
`some portion of it.
`
`III. PERSON OF ORDINARY SKILL IN THE ART
`
`23.
`
`I understand that my interpretation of the patent claims and my validity
`
`analysis must be undertaken from the perspective of a hypothetical person of
`
`ordinary skill in the art at the time of the claimed inventions or POSITA. In
`
`determining the characteristics of a hypothetical person having ordinary skill in the
`
`art of the asserted patents at the time of the claimed inventions, I considered several
`
`things, including the type of problems encountered in the art, the solutions to those
`
`problems, the rapidity with which innovations are made, the sophistication of the
`
`technology, and the education level and experience of people working in the field.
`
`It has further been explained to me by counsel for Patent Owner that the relevant
`
`timeframe is in or around September 13, 2005.
`
`24. Based on my experience, it is my opinion that a person of ordinary skill
`
`in the art at the time of the invention of the Asserted Patent would have had a
`
`SPACETIME3D
`EX2023 - PAGE 10
`
`
`
`Bachelor’s Degree in Computer Science or a related field, and two years of
`
`experience working in the field of computer graphics or graphical user interfaces or
`
`GUIs. An individual with less technical education but more experience, or vice
`
`versa, could also qualify as a person of ordinary skill in the art.
`
`25. Given my education and professional experience described in my initial
`
`declaration (EX2014) and in my curriculum vitae, I am in a position to opine on the
`
`understanding of a person of ordinary skill in the art of the ’048 patent.
`
`IV. CLAIM CONSTRUCTION
`
`26.
`
`I am informed that claim terms are construed under the standard
`
`provided by the U.S. Court of Appeals for the Federal Circuit in Phillips v. AWH
`
`Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc); 35 C.F.R. § 42.100(b). I am
`
`informed that under this standard claim terms are presumed to have their ordinary
`
`and customary meaning in light of the patent’s specification as understood by a
`
`person of ordinary skill in the art at the time of the invention, unless (1) the patentee
`
`acts as its own lexicographer by setting out a definition in the specification, or (2)
`
`the patentee disavows the full scope of a claim term in either the specification or
`
`during the prosecution of the patent.
`
`27. The parties agreed upon the following constructions, which I
`
`understand are derived from the Markman Order issued by the District Court in
`
`SpaceTime3D, Inc. v. Samsung Elecs. Co., Ltd., et al., No. 2:19-cv-00372-JRG (E.D.
`
`SPACETIME3D
`EX2023 - PAGE 11
`
`
`
`Tex.). EX2010. As I noted in my Prior Declaration, I have applied these
`
`constructions in my analysis below. As stated in my Prior Declaration, for the
`
`purposes of this IPR, the remaining terms should be interpreted as they would have
`
`been understood by a POSITA considering the context of the claims themselves, the
`
`specifications, the figures, the prior art, and the prosecution history and consistent
`
`with my experience in the relevant field.
`
`Term or Phrase
`“3D space”
`
`“2D space”
`
`“texturing”
`“replacing”
`
`Claim Construction
`“a virtual space defined by a three-dimensional coordinate
`system” (agreed upon)
`“a finite graphical area defined by a two-dimensional
`coordinate system” (agreed upon)
`No construction required (agreed upon)
`No construction required; ordinary meaning is “take the
`place of” (Patent Owner’s construction)
`
`
`V. ANALYSIS OF PETITIONER’S CITED PRIOR ART
`
`28. The analysis and opinions expressed in my Prior Declaration fully
`
`explain why the prior art cited by Petitioner in its Petition fails to disclose or render
`
`obvious each and every feature of the ’048 patent’s claims and explains in detail why
`
`a POSITA would not have been motivated to combine the cited prior art elements in
`
`a manner that the claimed invention. Petitioner’s expert, Dr. Fuchs, has considered
`
`my opinions and responded, or purported to respond to them, in his supplemental
`
`declaration. As noted below, in doing so in many instances Dr. Fuchs either
`
`SPACETIME3D
`EX2023 - PAGE 12
`
`
`
`misinterprets or misunderstands my positions, takes positions that are contrary to
`
`what the understanding of a POSITA would have been or inconsistent with his prior
`
`opinions, and introduces new arguments and prior art in an attempt to fill in gaps
`
`with respect to certain claim limitations that I pointed out were not disclosed in the
`
`cited prior art. While I understand that new arguments are not permitted in a reply
`
`and that Patent Owner argues that they should be excluded, below I analyze this new
`
`prior art and explain that even if it were to be considered, it fails to disclose the
`
`missing limitations identified out in my Prior Declaration. While I address certain of
`
`Dr. Fuchs’ position below, the fact that I have not addressed all of them should not
`
`be interpreted as agreement with them.
`
`A. Chronological Ordering of Objects in 3D Space
`
`29. For Ground 1, as previously noted, Petitioner relies on the combination
`
`of U.S. Patent No. 6,414,677 (“Robertson”) (EX1004), a book entitled “How the
`
`Internet Works,” by Preston Gralla (“Gralla”) (EX1005) and U.S. Patent Publication
`
`No. 2005/0086612 (“Gettman”) (EX1006). For Ground 2, Petitioner relies on the
`
`combination of U.S. Patent Publication No. 2006/0230356 (“Sauve”) (EX1007) and
`
`U.S. Patent No. 6,577,330 (“Tsuda”) (EX1008).
`
`1.
`
`Claim Interpretation
`
`30. Claim 1 is a method claim (not a system claim) and the claims
`
`themselves clearly recited an order to the claimed steps. It does so using the terms
`
`SPACETIME3D
`EX2023 - PAGE 13
`
`
`
`“first” and “second” and antecedent bases. For example, Claim 1 requires (i)
`
`receiving a first input (first website address) and a second input (second website
`
`address), (ii) receiving a first webpage in response to said first input and a second
`
`webpage in response to said second input, (iii) capturing a first image of said first
`
`webpage and a second image of said second webpage, and (iv) displaying a first
`
`object (including said first image) in the “foreground” and a second object (including
`
`said second image) in the “background.” EX1001, 37:49-38:3. A POSITA would
`
`have understood that this claim language recites a specific arrangement where the
`
`first requested webpage (or image thereof) is displayed in the foreground and the
`
`second requested webpage (or image thereof) is displayed in the background.
`
`31. This specific order is confirmed by Claim 6, where after both images
`
`are displayed in 3D space, a third input (third website address) is received from the
`
`user, resulting in receiving a third webpage, capturing a third image of the third
`
`webpage, and displaying a third object (including the third image) “in a further
`
`background of the 3D space, behind the second object.” EX1001, 38:43-54.
`
`32. A POSITA would have understood that this interpretation is not only
`
`explicit in the claim language and consistent with the specification but required to
`
`create a “3D GUI [that] can function as a visual chronological history of the user’s
`
`computing session.” EX1001 at 2:14-20, 5:6-21; see also id. at 29:23-38, Figure 11,
`
`and Figure 4B at 202 and 206. This can be seen in Figure 11 of the ‘048 Patent
`
`SPACETIME3D
`EX2023 - PAGE 14
`
`
`
`(reproduced below), where “an end user types http://www.yahoo.com … [and] the
`
`application then draws the HTML page through the proper web browser control into
`
`the 3D virtual space as depicted” (i.e., 510). Id. at 29:23-38. “This process can be
`
`repeated indefinitely, entering additional URLs … to have them filed in a 3D stack.”
`
`Id.
`
`
`
`33. This construction is also consistent with the prosecution history of the
`
`‘048 Patent. The “chronological order” discussed in the prosecution history that
`
`Petitioner and Dr. Fuchs refer to is how “icons are organized in linear chronological
`
`order”—not the claimed captured first and second images textured on first and
`
`second objects, respectively, wherein “the first object being displayed in a
`
`foreground of the 3D space and the second object being displayed in a background
`
`of the 3D space.” EX1002 at 329 (“generating a timeline that includes an icon for
`
`each object presented within the virtual space, wherein each of the icons are
`
`SPACETIME3D
`EX2023 - PAGE 15
`
`
`
`organized in linear chronological order according to when the objects were presented
`
`within the virtual space”). In substituting new claims for the original claims, several
`
`features were added and others deleted. For example, the “icon” feature was
`
`removed and the “at least two objects [displayed] within a three-dimensional virtual
`
`space” was amended to provide that “the first object [is] displayed in a foreground
`
`of the 3D space and the second object [is] displayed in a background of the 3D
`
`space.” Id. at 55-56.
`
`34. Dr. Fuchs contends that “[f]rom a POSITA’s perspective, the claims’
`
`reference to a ‘background’ and a ‘foreground’ implicates the relative position in the
`
`3D space and has no temporal or chronological relevance” and that “the numerical
`
`claim terms ‘first’ and ‘second’ also lack temporal or chronological relevance”
`
`because they are “just generic labels to keep track of the multiple webpages, inputs,
`
`and objects recited throughout the claims.” EX1060 at [82]-[83]. I disagree with
`
`Dr. Fuchs’ unsupported conjecture. First, this ignores the specific, ordered steps in
`
`the method claims, which I understand should be considered in interpreting method
`
`claims. Second, Dr. Fuchs ignores the specification’s disclosure that a “3D GUI can
`
`function as a visual chronological history of the user’s computing session” as
`
`illustrated in Figure 11. EX1001 at 2:14-20, 5:6-21; FIG. 11. Finally, his comment
`
`that the “Patent Owner surely would have used the word ‘chronological’” if it
`
`intended to arrange objects chronologically in 3D space is nothing but gratuitous
`
`SPACETIME3D
`EX2023 - PAGE 16
`
`
`
`speculation and a baseless assertion. A POSITA would have understood that there
`
`are many ways to describe and claim a chronological ordering of objects in 3D space.
`
`Indeed, using the terms “first” and “second” is a prime example of chronological
`
`ordering. Contrary to Dr. Fuchs’ assertion, a POSITA would not have understood
`
`that a chronological ordering can only be described using the word “chronological.”
`
`2. Ground 1: Robertson, Gralla and Gettman
`
`35. Aside from the claim interpretation argument, Dr. Fuchs does not
`
`otherwise opine that Robertson, Gralla or Gettman disclose the chronological
`
`placement of the objects as discussed above. I also agree that, properly construed,
`
`this prior art does not disclose a specific arrangement where the first requested
`
`webpage (or image thereof) is displayed in the foreground, the second requested
`
`webpage (or image thereof) is displayed in the background, and a subsequent (e.g.,
`
`third) requested webpage (or image thereof) is displayed further in the background.
`
`36. Reserved.
`
`3. Ground 2: Sauve and Tsuda
`
`37. As I previously explained, a POSITA would have understood that
`
`Sauve describes a traditional 2D, tabbed web browser, operating only in 2D space,
`
`with the addition of a “quick-pick user interface” for easily switching between a
`
`plurality of “content windows” (e.g., different web pages). Id. at [0025]. The quick-
`
`pick user interface includes “a graphical representation (e.g., thumbnails 402-411)
`
`SPACETIME3D
`EX2023 - PAGE 17
`
`
`
`for each of the open tabs” (e.g., different web pages). Id. at [0042]. This can best
`
`be seen in Figure 4 of Sauve, reproduced below. EX2014 at [111].
`
`
`
`38. As Figure 4 makes clear, Sauve operates exclusively in 2D space and
`
`therefore does not disclose anything displayed in 3D space, let alone the foreground
`
`or background.
`
`39. Contrary to Petitioner and Dr. Fuchs’ assertion, Sauve does not disclose
`
`that the thumbnails are arranged “chronologically.” To be sure, as shown in FIG. 4
`
`and described in the specification, the thumbnails are arranged numerically.
`
`EX1007 at [0042]-[0043]. However, a POSITA would understand that the numbers
`
`are used to identify different “Thumbnail Sites X” and do not reflect the order in
`
`SPACETIME3D
`EX2023 - PAGE 18
`
`
`
`which the sites were opened. While Dr. Fuchs’ baldly asserts this, critically he does
`
`not provide any citations to Sauve disclosing that the site numbers actually refer to
`
`the chronology when the webpage was opened.
`
`40. Petitioner relies on U.S. Patent No. 6,577,330 (“Tsuda”) (EX1008) for
`
`describing a 3D GUI where objects are rendered in a simulated 3D space in order to
`
`increase the amount of information that can be presented on a given screen. Tsuda
`
`presenting at least a portion of each window in the foreground of the 3D space. This
`
`can be seen in Figure 5, reproduced below.
`
`
`
`41. According to Tsuda, windows are displayed in the foreground, either in
`
`their entirety or “inclined in a depth direction, so that the key part of the display
`
`content is near the front of the 3D space [i.e., in the foreground]. Therefore, even if
`
`a plurality of windows are being displayed, the user can grasp the type and display
`
`content of each window at a glance.” Id. at 2:13-26.

`
`chronological ordering of the images. Dr. Fuchs does not dispute this in his
`
`declarations.

`
`45. The proposed combination of Sauve and Tsuda would not result in the
`
`claimed chronological ordering of the images because neither Sauve nor Tsuda
`
`disclose a chronological ordering of the images.
`
`46. Even assuming that Sauve’s FIG. 4 site identifier numbers refer to a
`
`specific chronology (they do not) and that Tsuda’ FIG. 11B discloses that the
`
`rightmost window is in a foreground and windows to the left are in the background
`
`(which it does not), the claimed order does not exist in the combination proposed by
`
`Petitioner. According to the claims, the first requested website (or image thereof) is
`
`displayed in the foreground, with subsequently requested websites (or images
`
`thereof) displayed further in the background. This is the exact opposite of the order
`
`of Petitioner’s proposed combination. According to Dr. Fuchs, “a POSITA would
`
`have known that tabs are arranged chronologically [with] [t]he initial tab [being] on
`
`the far left, with each subsequently opened tab to the right of the one that came
`
`before.” EX1006 at [96]. Combining this with Tsuda would result in the first opened
`
`SPACETIME3D
`EX2023 - PAGE 20
`
`
`
`tab in the background and the most recently opened tab in the foreground, which is
`
`the opposite of that which is claimed.
`
`47. The claimed order would also not be obvious as doing so would bury
`
`the most recently opened webpage in the background. The ‘048 Patent can function
`
`in this way as the 3D space is “immersive,” allowing “the end user … to achieve
`
`multiple, unique viewpoints in the virtual space by moving closer to ro way from an
`
`object in the virtual space.” EX1001 at 15:43-54. This movement along the z-axis
`
`can be accomplished, for example, by interacting with the navigator 320, timeline
`
`340, or compass 440. See, e.g., EX1001 at Fig. 11. Such features are not disclosed
`
`in either Sauve or Tsuda. As such, a POSITA would not have been motivated to
`
`“bury” the most recently opened webpage in the background of the 3D space. In
`
`fact, Tsuda teaches the exact opposite, where the webpage currently being interacted
`
`is presented in the foreground, “rotated to face the front.” See, e.g., EX1008 at Fig.
`
`12B at 18:46-53.
`
`48. A POSITA would not have been motivated to combine Tsuda and
`
`Sauve as suggested by Petitioner as doing so would not only fail to address the
`
`problems presented in Sauve but would do so in a way that is contrary to the
`
`teachings of Tsuda. For example, as I discuss in greater detail below, the Petitioner’s
`
`proposed combination, which buries webpages deep within the 3D space, would not
`
`allow the user to distinguish one webpage (or tab) from another (i.e., the purpose of
`
`SPACETIME3D
`EX2023 - PAGE 21
`
`
`
`Sauve) and would be contrary to the teachings of Tsuda, which criticizes objects
`
`being “positioned deep within the 3D space” as “all the window display content
`
`[becomes] unreadable.” citing EX1008 at 1:56-60.

`
`“The Rendered First Webpage”
`
`1.
`
`Claim Interpretation
`
`50. Claim 1 provides that, after “receiving first and second webpages from
`
`at least one server in response to said first and second inputs, wherein the first and
`
`second inputs are website addresses corresponding to said first and second
`
`webpages, respectively,” the claimed method requires “rendering the first and
`
`second webpages.” EX1001, 37:51-61. Subsequently, upon interacting with the
`
`first image, the claims recite “replacing the first and second objects within the 3D
`
`space with a window within a two-dimensional (2D) space in response to receiving
`
`the interaction, wherein the window includes the rendered first webpage.” Id., 38:4-
`
`10 (emphasis added).
`
`51. The 3D GUI disclosed in the ‘048 Patent provides “a visual history of
`
`the user’s computing session” (EX1001 at 5:6-11) where images in 3D space are
`
`updated to reflect interactions with the active webpage in 2D space. This is
`
`accomplished by capturing images. See, e.g., Claims 1 and 6. However, it is also
`
`important that the webpages presented in 2D space mirror the images in 3D space.
`
`SPACETIME3D
`EX2023 - PAGE 22
`
`
`
`This is accomplished by “replacing the first and second objects within 3D space with
`
`a window within two-dimensional space in response to receiving the interaction,
`
`wherein the window includes the rendered first webpage” (id. at 38:7-10) (emphasis
`
`added), where “the rendered first webpage” is the webpage that was requested by
`
`the user via the “first input” from which the “first image” was captured. By replacing
`
`the images with the previously rendered webpage, the user is presented with a
`
`webpage that matches (or is identical to) the one that is visually depicted in 3D
`
`space, and does so with minimal delay.
`
`52. Petitioner argues that Patent Owner is attempting to inject language into
`
`the claims and that “[t]he claims [only] require that the ‘first webpage’ of the
`
`‘replacing’ step is the same ‘first webpage” from the earlier recited ‘receiving,’
`
`‘rendering,’ and ‘displaying’ steps. Nothing more.” Reply at 6-7. Those skilled in
`
`the art would find that Petitioner’s interpretation is incorrect. Petitioner’s
`
`interpretation actually results in reading the term “rendered” out of the “replacing”
`
`step. The claims do not recite “the first webpage” but “the rendered first webpage.”
`
`Thus, those skilled in the art would understand that the claims are not referring to
`
`the webpage in general, but the rendered version from which the corresponding
`
`image was captured.
`
`53. Petitioner’s next argument is that this feature is “absent from the
`
`specification.” Reply at 7. Again, this is not true. The specification provides that
