`
`INTRODUCTION
`This proceeding returns to the Board after an appeal of a final written deci-
`
`sion (Paper 54) that found that Petitioner had “failed to muster sufficient evidence
`
`to demonstrate…that Ogata’s lens could have been scaled to work in Parulski’s
`
`camera with a reasonable expectation of success.” See Apple Inc. v. Corephotonics,
`
`Ltd., 81 F.4th 1353, 1361 (Fed. Cir. 2023) (“Remand Decision”); IPR2020-00906,
`
`Dec. at 2, 19. The Court of Appeals determined that the Board, in violation of the
`
`Administrative Procedure Act (APA), had based its decision on a ground not raised
`
`by any party. Remand Decision, 81 F.4th at 1354.
`
`“Because the Board based its decision on a typographical error without
`
`sufficiently explaining its significance, made sua sponte findings that lacked
`
`substantial evidence, and did not resolve the issue the parties presented,” the Court
`
`vacated and remanded for “further proceedings that meet APA’s requirements for
`
`notice and the opportunity to respond.” Id. at 1362. According to the Court, the
`
`Board focused on “an issue that no party meaningfully raised or asserted was
`
`relevant. And because the Board’s analysis was focused on this issue, it failed to
`
`thoroughly assess the critical issue outlined by the parties, i.e., whether there
`
`would have been a reasonable expectation of success in combining Parulski and
`
`Ogata, considering manufacturing and scalability concerns.” Id. at 1362 (quoting
`
`from Power Integrations v. Lee, 797 F.3d 1318, 1325 (Fed. Cir. 2015)) (internal

`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`In its post-remand Order, the Board requests briefing on: (1) what consti-
`
`tutes an APA-compliant decision on remand, (2) whether it can consider on
`
`remand issues that it has sua sponte considered to be errors, and (3) what evidence
`
`currently in the record supports Petitioner’s contentions that Ogata’s embodiment I
`
`lens and Kawamura’s example 1 lens can be scaled to project images onto a 1/2.5”
`
`image sensor compatible with Parulski’s digital camera, what weight should be
`
`given to that evidence, and why. See (Order of Conduct) Paper 60 at 11.
`
`II.
`
`DISCUSSION
`A. APA-Compliant Decision on Remand
`
`The APA generally requires “the Board [to] base its decision on arguments
`
`that were advanced by a party, and to which the opposing party was given a chance
`
`to respond.” In re IPR Licensing, Inc., 942 F.3d, 1363, 1368-69 (Fed. Cir. 2019).
`
`In limited circumstances the Board may raise issues sua sponte, but to do so it
`
`must “give[] the parties notice and an opportunity to respond.” Nike Inc. v. Adidas
`
`AG, 955 F.3d 45, 53 (Fed. Cir. 2020). The Board ran afoul of these principles.
`
`Specifically, the Board’s determination that a typographical error in Dr.
`
`Sasián’s declaration was dispositive of the issues in the case did not comport with
`
`notice requirements of the APA. See Remand Decision, 81 F.4th at 1362
`
`(“Apple…had no reason to anticipate that the typographical error would be the
`
`4855-1382-0829 v.2
`
`
`- 2 -
`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`basis for the Board’s decision, given that the parties did not brief, argue, or even
`
`
`
`suggest this error was dispositive or would impact the claimed lens parameters.”)
`
`On remand, the Board should base its decision on arguments that were
`
`actually advanced by a party. Doing so would help to ensure adequate grounds for
`
`the Board’s decisions and avoid “red herring” arguments not tested by adversarial
`
`briefing or firmly anchored in an evidentiary record. To the extent that the panel’s
`
`briefing order suggests that the Board may persist in sua sponte issues that were
`
`already addressed with disfavor by the reviewing court or that it posits further sua
`
`sponte issues (see Paper 60 at 3-7), it must afford Petitioner a meaningful right to
`
`respond, including testimonial evidence from its expert.
`
`1.
`
`Board Should Base its Decisions on Arguments Advanced
`by a Party and to which the Opposing Party was Given a
`Chance to Respond
`Under the APA's notice provisions relevant to Board proceedings, “persons
`
`entitled to notice of an agency hearing shall be timely informed of...the matters of
`
`fact and law asserted,” and the Board “shall give all interested parties opportunity
`
`for...the submission and consideration of facts [and] arguments.” 5 U.S.C.
`
`§§554(b)(3), (c)(1). The Board “must base its decision on arguments that were
`
`advanced by a party, and to which the opposing party was given a chance to
`
`respond.” Masimo Corp. v. Apple Inc., 2023 WL 5921622 (Fed. Cir. Sep. 12,
`
`2023) (quoting In re Magnum Oil Tools Int'l, Ltd., 829 F.3d 1364, 1381 (Fed. Cir.
`
`4855-1382-0829 v.2
`
`
`- 3 -
`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`2016); see also 81 F.4th at 1362 (Board erred here when analysis focused on “an
`
`
`
`issue that no party meaningfully raised or asserted was relevant”); Alacritech, Inc.
`
`v. Intel Corp., 966 F.3d 1367, 1372 (Fed. Cir. 2020) (Board erred where its
`
`“reasoning appear[ed] to be untethered to either party's position”).
`
`Moreover, the APA requires the Board to “provide an adequate ground” for
`
`its decisions. Power Integrations, 797 F.3d at 1325 (quoting In re Thrift, 298 F.3d
`
`1357, 1366 (Fed. Cir. 2002)). The reviewing court has explained that the Board
`
`fails to satisfy this obligation when it misapprehends or ignores the parties’
`
`arguments and instead “focuse[s] on a red herring.” See id. (Board spent a “signifi-
`
`cant portion of [its] opinion…rejecting an argument that [a party] never made.”).
`
`Because so much of the Board’s analysis has been focused on red herring—an
`
`Abbe number data-entry error and a nonexistent inconsistency in aspherical surface
`
`data—“it failed to thoroughly assess the critical issue outlined by the parties, i.e.,
`
`whether there would have been a reasonable expectation of success in combining
`
`Parulski and Ogata considering manufacturing and scalability concerns.” See
`
`Remand Decision, 81 F.4th at 1361-62 (analogizing Power Integrations).
`
`2.
`
`An Issue Raised Sua Sponte by the Board Requires Notice
`and Opportunity to Respond
`The Board may consider an issue that it raises sua sponte only after giving
`
`notice of the issue and only after affording the parties—and particularly the party
`
`against which the supposed issue is raised—an opportunity to respond on the issue.

`
`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`See Remand Decision, 81 F.4th at 1360 (citing Magnum Oil Tools, 829 F.3d at
`
`
`
`1381; Nike, 955 F.3d at 53). Moreover, opportunity to respond includes reasonable
`
`opportunity to present argument and evidence on the new issue raised sua sponte
`
`by the Board. See Axonics, Inc. v. Medtronic, Inc. 75 F.4th 1374, 1383 (Fed. Cir.
`
`2023). The Axonics requirement for reasonable opportunity to present argument
`
`and evidence is consistent with the APA requirements that the Board must give
`
`parties “opportunity for…the submission and consideration of facts [and]
`
`arguments,” and permit parties “to submit rebuttal evidence, and to conduct such
`
`cross-examination as may be required for a full and true disclosure of the facts.” 5
`
`U.S.C. §§554(c), 556(d).
`
`B.
`
`Supposed Errors that the Panel Raised (or Raises) sua sponte
`Relative to Dr. Sasián’s Expert Testimony may Not be Considered
`without Notice and a Meaningful Opportunity to Respond
`
`Here, two supposed issues/errors were raised sua sponte in the final written
`
`decision (Paper 54) referenced by, and now reprised in, the panel’s briefing Order
`
`(Paper 60). Each supposed issue/error was noted with disfavor by the reviewing
`
`court. See Remand Decision, 81 F.4th at 1361-62. In addition, the panel now raises
`
`a further issue regarding Kawamura—again sua sponte. See Paper 60 at 5-7.
`
`Where, as arguably here, the panel assumes for itself an extra-judicial role as
`
`technical expert, it should be mindful that the party against whom the panel offers
`
`its expertise has no procedural path to cross-examine the panel (or panelist) or
`
`4855-1382-0829 v.2
`
`
`- 5 -
`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`offer countervailing evidence—whether offered expertise turns out to be insightful,
`
`
`
`misguided, or introduces red herring. See In re Zurko, 258 F.3d 1379, 1386 (Fed.
`
`Cir. 2001) (“With respect to core factual findings in a determination of patentabil-
`
`ity…the Board cannot simply reach conclusions based on its own understanding or
`
`experience…. Rather, the Board must point to some concrete evidence in the rec-
`
`ord in support of these findings. To hold otherwise would render the process of
`
`appellate review for substantial evidence on the record a meaningless exercise”).
`
`Petitioner addresses each of the Board’s sua sponte issues in a manner
`
`consistent with the limitation imposed by the panel that “no additional or
`
`supplemental evidence may be submitted.” Paper 60 at 11. However, for avoidance
`
`of doubt, this limitation conflicts with precedent and statute (see supra discussion
`
`of Axonics, 5 U.S.C. §§554(c), 556(d)), and Petitioner requests the opportunity to
`
`present supplemental evidence on each sua sponte issue raised by the Board.
`
`1.
`
`Supposed Error Regarding Abbe Number for Ogata’s
`Third Lens Element is a Red Herring
`As observed by the reviewing Court, “Abbe number is neither recited in the
`
`challenged claims nor does the record contain any evidence that it impacts any lens
`
`parameter that is recited in the challenged claims.” Remand Decision, 81 F.4th at
`
`1361. For at least this reason, the Board should recognize lack of substantial basis
`
`for it to rely on an Abbe number error for Ogata’s third lens element and sua
`
`sponte “call[] into question Petitioner’s contention that a person skilled in the art
`- 6 -
`
`4855-1382-0829 v.2
`
`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`would have known that Ogata’s lens could be scaled to work in Parulski’s camera
`
`
`
`with a reasonable expectation of success.” See Dec. at 16. No party has argued that
`
`Abbe number affects a scaling analysis. Moreover, the record indicates that
`
`Ogata’s lens exhibited excellent optical performance at its original, embodiment I
`
`scale (see APPL-1021, ¶36; APPL-1026, 3:4-5) and, as scaled, maintains excellent
`
`performance (see APPL-1021, FIG. 3B (evidenced by field curvature and OPD fan
`
`plots)) even with the apparent Abbe number error. Whatever Dr. Moore’s opinion
`
`regarding a hypothetically “significant change” in refractive index or Abbe number
`
`on performance of a lens design (see Dec. at 15 (citing Ex. 2015, ¶88)), it is not se-
`
`riously contended that this Abbe number error suggests an “unacceptable design.”
`
`Petitioner will offer further testimonial evidence of non-materiality, if permitted.
`
`2.
`
`Supposed Discrepancy Regarding Fourth- and Tenth-Order
`Aspheric Terms is also a Red Herring
`Although the panel does not overtly reprise its supposed concerns regarding
`
`data for fourth- and tenth-order terms for aspheric surfaces in its briefing Order, it
`
`does reference a span of pages which included the imagined issue. See Paper 60 at
`
`5 (citing Dec. at 13-16). As observed by the reviewing Court, supposed aspheric
`
`surface data “inconsistencies” were not even errors. Id. at 1362 (noting apparent
`
`agreement of parties). Fourth- and tenth-order terms are non-linear terms and vari-
`
`ances in these terms due to linear scaling are entirely expected. The Board has sua
`
`sponte introduced an issue without basis; no party has or could reasonably advance
`- 7 -
`
`4855-1382-0829 v.2
`
`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`such theory to call into question expectation of success. Petitioner will offer further
`
`
`
`testimonial evidence disposing of this supposed issue, if permitted.
`
`3.
`
`The Board’s Newly Articulated Concern Regarding Lens
`Prescription Data for Kawamura is Entirely Speculative
`Finally, the panel raises a newly-articulated concern on remand related to
`
`lens prescription data for Kawamura. See Paper 60 at 5-7. The panel asserts (again
`
`sua sponte and again without basis in any argument of Patent Owner) that “Dr.
`
`Sasián entered into the Zemax Lens Data Editor…[data that] differs from the lens
`
`prescription data for Kawamura’s example 1 lens” (Id. at 5), presumably laying
`
`groundwork for it (or Patent Owner) to now speculate that Dr. Sasián’s scaling
`
`analysis of Kawamura is unreliable. The panel summarizes its newly-articulated
`
`concern in a table comparing refractive index and Abbe number values appearing
`
`in Kawamura itself with differing values appearing in Appendix Fig. 4C. Id. at 6.
`
`For avoidance of any doubt, Dr. Sasián’s scaling analysis of the Kawamura
`
`lens assembly was performed using the prescription data from Kawamura itself,
`
`not any extraneous data depicted in Appendix Fig. 4C. Moreover, Appendix Fig.
`
`4C is not even referenced in Dr. Sasián’s scaling analysis. As detailed below in
`
`Section II.C.2, the record supports Petitioner’s contention regarding scaling of
`
`Kawamura’s lens for Parulski’s digital camera by illustrating progression from
`
`Kawamura’s dimensionless cross-section (APPL-1012, Fig. 1), using Kawamura’s
`
`prescription data (APPL-1012, 3 (table for Example 1)), and applying Smith’s
`- 8 -
`
`4855-1382-0829 v.2
`
`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`teaching of scaling to explain that Kawamura’s lens assembly, scaled to a 1/2.5”
`
`
`
`image sensor, results in an assembly with 5.72mm EFL, 6.892mm TTL, 63.4º FOV
`
`and f/2.9. Moreover, Dr. Sasián’s ray trace and cross-section based on his Zemax
`
`modeling of the scaled Kawamura lens assembly clearly shows five lens elements
`
`consistent with Kawamura’s dimensionless cross-section, not six associated with
`
`some other lens assembly. Petitioner will offer further testimonial evidence of non-
`
`materiality of the Appendix Fig. 4C data, if permitted.
`
`C. The Record Supports Petitioner’s Contention regarding Scaling
`of Ogata’s Lens for Parulski’s Digital Camera
`
`The panel’s briefing order asks “what evidence currently in the record sup-
`
`ports Petitioner’s contention that [Ogata’s lens] can be scaled by a POSITA to pro-
`
`ject images onto [a] 1/2.5” image sensor [such as for] Parulski’s digital camera?”
`
`Paper 60 at 11. The answer is that the Petition is supported by Dr. Sasián’s
`
`testimony (including his modeling of the scaled lens assembly in Zemax), Dr.
`
`Durand’s testimony,1 and various supporting references that all demonstrate that
`
`
`1 Dr. Durand, like Dr. Sasián, testifies as to the reasons that a POSITA would look
`
`to scale Ogata’s wide-angle lens assembly for use in Parulski’s dual-aperture
`
`digital camera, to the characteristics of the scaled Ogata lens assembly (5.72mm
`
`focal length, 6.892mm TTL, 63.4º FOV, f/2.9 result) per Smith, and ultimately that
`
`a POSITA would have recognized that Ogata could have been successfully scaled
`
`4855-1382-0829 v.2
`
`
`- 9 -
`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`Ogata’s lens assembly can be scaled to the 5.72mm focal length appropriate for a
`
`
`
`1/2.5” image sensor. See Pet., 24-28; (Sasián) APPL-1021, ¶¶35-39; (Durand)
`
`APPL-1003, ¶¶56-60; (Smith) APPL-1020, 57. Notwithstanding the red herring
`
`issues raised sua sponte by the Board previously and reprised in the briefing Order,
`
`Petitioner’s scaling analysis is straightforward and indicates that a POSITA could
`
`have—and indeed would have—scaled Ogata’s lens assembly to have a 5.72mm
`
`focal length appropriate for a 1/2.5” image
`
`sensor and Parulski’s digital camera.
`
`Dr. Sasián’s analysis starts with a wide-
`
`angle lens assembly that Ogata illustrates (as
`
`is conventional) as a dimensionless cross-
`
`section. (Ogata) APPL-1026, Fig. 1 (ex-
`
`plained in APPL-1021, ¶¶35; see also Pet.,
`
`
`for use with a 1/2.5” image sensor. APPL-1003, ¶¶56-65. Dr. Durand also testifies
`
`as to how Ogata’s scaled lens assembly meets a need of Parulski for such an
`
`assembly and as to a POSITA’s reasonable expectation of success in making the
`
`combination. APPL-1003, ¶¶61-65. Dr. Sasián, having personal knowledge of the
`
`Zemax model, testifies as to those same characteristics of the scaled Ogata lens
`
`assembly (embodiment I) as shown after scaling in Zemax. APPL-1021, ¶39.
`
`4855-1382-0829 v.2
`
`
`- 10 -
`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`24-25). Note the dimensionless nature of the lens assembly cross-section and the
`
`
`
`exemplary dimensional and other parameters of Ogata’s embodiment I lens pre-
`
`scription. APPL-1026, 7:35-61 (detailed in APPL-1021, ¶36; see also Pet., 25-26).
`
`From there, Dr. Sasián
`
`explains the viability and math-
`
`ematical nature of scaling, in-
`
`cluding which dimensions and
`
`measures are affected by scal-
`
`ing, which are not, and for those
`
`that are affected, how they are
`
`affected. APPL-1021, ¶¶35-39.
`
`Notably, linear aberrations—
`
`like the dimensions specified by
`
`the lens prescription—scale
`
`along with the design. This means that as the lens assembly is scaled down, the lin-
`
`ear aberrations lessen, ultimately improving the optical performance of the lens as-
`
`sembly in that regard. APPL-1021, ¶27; see also (Smith) APPL-1020, p.57 (“A
`
`lens prescription can be scaled to any desired focal length simply by multiplying
`
`all of its dimensions by the same constant. All of the linear aberration measures
`
`will then be scaled by the same factor. Note however, that percent distortion, chro-

`
`matic difference of magnification (CDM), the numerical aperture or f number, ab-
`
`
`
`errations expressed as angular aberrations, and any other angular characteristics re-
`
`main completely unchanged by scaling”); see also APPL-1003, ¶58; Pet., 26 (typos
`
`in APPL-1020 refs to Smith).
`
`Finally, Dr. Sasián explains the 5.72mm focal length, 6.892mm TTL, 63.4º
`
`FOV, f/2.9 result of scaling Ogata to a 1/2.5” image sensor. APPL-1021, ¶¶37-39.
`
`This scaling is consistent with Smith’s referenced teaching (see APPL-1020, 57),
`
`and an illustration of the
`
`scaled Ogata lens assem-
`
`bly (5.72447mm EFL,
`
`6.89155mm TTL) is pre-
`
`sented in the Petition,
`
`showing a cross-section
`
`of the lens assembly and
`
`ray-trace data generated
`
`by Zemax. The illustra-
`
`tion (reproduced here) is consistent with Dr. Sasián’s analysis, the analysis in the
`
`Petition, and that in Dr. Durand’s motivation to combine analysis. The ray-trace
`
`and cross-section for the scaled (5.72mm focal length) Ogata lens assembly
`
`demonstrates that Ogata can be scaled by a POSITA to project images onto a
`
`4855-1382-0829 v.2
`
`

`
`
`
`Petitioner’s Brief Post-Remand
` IPR2020-00906 (Patent No. 10,225,479)
`
`1/2.5” image sensor such as for Parulski’s digital camera. Patent Owner has not
`
`
`
`challenged the accuracy of the model or the ability of a POSITA to scale Ogata’s
`
`lens in this way. Patent Owner’s own expert (Dr. Moore) confirmed in deposition
`
`the routine nature of scaling. APPL-1041, 89:13-94:20 (factor of 10 or 100).
`
`The weight of the foregoing evidence is great in that (i) it is corroborated by
`
`two experts, (ii) it demonstrates both the ability to scale Ogata to a 1/2.5” image
`
`sensor and the results of such scaling insofar as all relevant claimed parameters are
`
`concerned, (iii) the testimonial evidence is supported by underlying authority in the
`
`field (e.g., Smith), and (iv) the scaling analysis taught by Smith and to which both
`
`Drs. Sasián and Durand testify is confirmed computationally in Zemax modeling
`
`performed by Dr. Sasián.
`
`D. The Record Supports Petitioner’s Contention regarding Scaling
`of Kawamura’s Lens for Parulski’s Digital Camera
`
`The briefing Order also asks what evidence currently in the record supports
`
`Petitioner’s contention that Kawamura’s lens can be scaled by a POSITA to project
`
`images onto a 1/2.5” image sensor such as for Parulski’s digital camera. Paper 60
`
`at 11. The answer is again that the Petition is supported by Dr. Sasián’s testimony
`
`(including his modeling of the scaled lens assembly in Zemax), Dr. Durand’s testi-
`
`mony,2 and various supporting references which all demonstrate that Kawamura’s
`
`
`2 Dr. Durand, like Dr. Sasián, testifies to the reasons that a POSITA would look to

`
`lens assembly can be scaled to the 16.33 mm focal length appropriate for a 1/2.5”
`
`
`
`image sensor. See Pet., 17-21;
`
`(Sasián) APPL-1021, ¶¶40-45;
`
`(Smith) APPL-1020, 57.
`
`Dr. Sasián’s analysis starts
`
`with the Kawamura telephoto lens
`
`assembly that is—as is again
`
`conventional—a dimensionless cross-section. See (Kawamura) APPL-1012, Fig. 1
`
`
`scale Kawamura’s telephoto lens assembly for use in Parulski’s dual-aperture
`
`digital camera, to the characteristics of the scaled Kawamura lens assembly
`
`(16.33mm focal length, 15.343mm TTL, 24.3º FOV, f/4.0) per Smith, and
`
`ultimately to the point that POSITA would have recognized that Kawamura can
`
`be—and would have been—successfully scaled for use with a 1/2.5” image sensor.
`
`APPL-1003, ¶¶44-55. Dr. Durand also testifies as to how Kawamura scaled lens
`
`assembly meets a need of Parulski for such an assembly and to POSITA’s
`
`reasonable expectation of success in making the combination. APPL-1003, ¶¶50-
`
`55. Dr. Sasián, having personal knowledge of the Zemax model, testifies as to
`
`those same characteristics of the scaled Kawamura lens assembly (example 1) as
`
`shown after scaling in Zemax. APPL-1021, ¶45.

`
`(explained in APPL-1021, ¶35; see also Pet., 24-25; APPL-1003, ¶46 (annotating
`
`
`
`to identify lens elements)). As with Ogata, the Kawamura lens assembly cross-
`
`section is dimensionless, and at one exemplary scale has dimensional and other
`
`parameters of Kawamura’s example 1
`
`prescription. See APPL-1012, 3 (table for
`
`Example 1).
`
`From there, Dr. Sasián explains the vi-
`
`ability and mathematical nature of scaling,
`
`including which dimensions and measures
`
`are affected by scaling, which are not, and
`
`for those that are affected, how they are af-
`
`fected. APPL-1021, ¶¶40-45. As before, linear aberrations—like the dimensions
`
`specified by the lens prescription—scale with the design. As before, the result is
`
`smaller linear aberrations for the scaled down lens. APPL-1021, ¶43 (citing
`
`(Smith) APPL-1020, p.57); see also APPL-1003, ¶47; Pet., 19 (typos in APPL-
`
`1020 refs to Smith).
`
`Finally, Dr. Sasián explains the 16.33mm focal length, 15.343mm TTL,
`
`24.3º FOV, f/4.0 result of scaling Kawamura (i.e., of scaling the example 1 pre-
`
`scription data for the FIG. 1 lens assembly cross-section) to a 1/2.5” image sensor.
`
`APPL-1021, ¶¶43-45. This scaling is consistent with Smith’s referenced teaching
`
`4855-1382-0829 v.2

` IPR2020-00906 (Patent No. 10,225,479)
`
`(see APPL-1020, 57), and an illustration of the scaled Kawamura lens assembly
`
`
`
`(16.3302mm EFL, 15.34309mm TTL) is presented in the Petition, showing a
`
`cross-section of the lens assembly and ray-trace data as generated by Zemax. This
`
`illustration (reproduced below) is consistent with Dr. Sasián’s analysis, the
`
`analysis in the Petition, and Dr. Durand’s motivation to combine analysis.
`
`The ray-trace and cross-section for the scaled (16.33mm focal length)
`
`Kawamura lens assembly
`
`demonstrates that Kawa-
`
`mura’s lens can be scaled
`
`by a POSITA to project
`
`images onto a 1/2.5” im-
`
`age sensor such as for Pa-
`
`rulski’s digital camera.
`
`APPL-1021, ¶45. Patent
`
`Owner has not challenged the accuracy of the model or the ability of POSITA to
`
`scale Kawamura’s lens in this way. APPL-1041, 89:13-94:20 (factor of 10 or 100).
`
`The weight of the foregoing evidence is great in that (i) it is corroborated by
`
`two experts, (ii) it demonstrates both the ability to scale Kawamura to a 1/2.5”
`
`image sensor and the results of such scaling insofar as all relevant claimed
`
`parameters are concerned, (iii) the testimonial evidence is supported by underlying
`
`4855-1382-0829 v.2

`
`authority in the field (e.g., Smith), and (iv) the scaling analysis taught by Smith
`
`
`
`and to which both Drs. Sasián and Durand testify is confirmed computationally in
`
`Zemax modeling performed by Dr. Sasián.
`
`III.
`
`CONCLUSION
`On remand, the Board should base its decision on arguments that were
`
`actually advanced by a party. Although the Board may raise issues sua sponte, if it
`
`does so, it must give the parties notice and an opportunity to respond. Here, the
`
`opportunity to respond must, per the requirements of Axonics and the APA, include
`
`reasonable opportunity to present rebuttal evidence. Because the panel has limited
`
`post remand briefing such that “no additional or supplemental evidence may be
`
`submitted,” it should base its decision on remand solely on arguments that were
`
`actually advanced by a party at trial. Alternatively, if the Board wishes to proceed
`
`with issues it raised sua sponte, it must allow rebuttal evidence.
`
`Regardless, record evidence supports Petitioner’s contentions that Ogata’s
`
`embodiment I lens and Kawamura’s example 1 lens can be scaled to project
`
`images onto the 1/2.5” image sensor such as for Parulski’s digital camera, and the
`
`Board should hold claims 19-22 obvious on the Parulski/Ogata/Kawamura-based
`
`combinations advanced by Petitioner.
