“A. Legal Standards — Petitioner’s Burden “In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the 1 Amendments to 35 U.S.C. § 103 enacted by the Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”) took effect in March 2013. The ’353 patent issued from an application filed in September 2004. See Ex. 1001, code (22). Thus, we apply the pre-AIA version of § 103. grounds for the challenge to each claim”)). This burden of persuasion never shifts to the patent owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). B. Legal Standards — Obviousness A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter 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 said subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness, if made available in the record, which has not happened here.

“C. Level of Ordinary Skill in the Art Petitioner contends a person having ordinary skill in the art pertaining to the ’353 patent “would have possessed at least a four-year degree in physics, biophysics, medical physics, or a related field, and two years of experience in developing and/or applying computed tomography methods,” wherein “[a]dditional education and professional experience are interchangeable.” Pet. 1; Ex. 1003 ¶¶ 54–55. “Patent Owner utilizes Petitioner’s proposed level of skill in the art.” Prelim.

“(iii) Analysis Based on the present record, we determine Petitioner’s contentions regarding the third step of claim 1 are supported sufficiently by the cited disclosures in Weese and Dr. Peterson’s testimony to justify institution of review. In particular, Weese describes obtaining a plurality of second images of the patient’s internal organs (i.e., PET image I0 in Fig. 1, and PET image I10 in Fig. 3) using a second imaging technique (i.e., PET). See Ex. 1005, Figs. 1, 3, and 6, ¶¶ 47–49, 58–59, 72. In particular, PET image I0 in Figure 1 may be a reconstructed “volume image[]” composed of a plurality of “quasi two-dimensional” “slice images” that, when combined, represent a three-dimensional region inside the patient. Id. ¶¶ 48, 58, 61; see also Pet. 56–57. PET image I10 in Figure 3 may be a similarly reconstructed volume image composed of a plurality of slice images.4 See 4 We do not rely here on Petitioner’s alternative theory that Weese discloses a “plurality” of second images because PET images I0 and I10 are “superposed” images encompassing “several states of motion.” Pet. 58. Ex. 1005 ¶¶ 61, 83–84. Patent Owner’s sole opposition to Petitioner’s assertions in this regard are limited to whether Weese “obtain[s]” PET images I0 and I10 as recited in claim 1, which we address below. Also, it appears that PET images I0 and I10 are obtained while also obtaining second movement measurements of the patient’s internal organs using a second sensor system (i.e., motion acquisition unit 12 and motion sensor 15 / S1) which is independent from the PET imaging technique. See Ex. 1005, Figs. 1 and 6, ¶ 65 (“[T]he respiratory motion is determined during the acquisition of the PET projections P1 by means of a respiratory motion sensor provided on the patient and therefrom the frequency function f(r) or, more generally, a state of motion function F1 is derived for the construction of the motion model M2.”). Furthermore, Weese describes how frequency function f(r) is utilized to facilitate image comparison between CT and PET images at common motion states. See id. ¶¶ 31, 49–51, 70–71, 75–77, 79–80, 83; see also Ex. 1003 ¶¶ 214–216 (Dr. Peterson’s supporting testimony). Patent Owner’s sole opposition to Petitioner’s assertions in this regard are limited to whether Weese “obtain[s]” PET images I0 and I10 as recited in claim 1, which we address below. Patent Owner’s two opposing arguments are unavailing, based on the present preliminary record. First, Petitioner relies on reconstructed PET images I0 and I10 as satisfying the “plurality of second images” recited in claim 1, not PET projections P1 from which PET images I0 and I10 are derived. See, e.g., Pet. 56, 58 (“I0 and I10 disclose and render obvious a ‘plurality of second images’ in two ways” — “I0 and I10 may be ‘volume images’ formed using ‘known’ techniques,” and “I0 and I10 are ‘superposed’ PET images encompassing ‘several states of motion,’ which” slip op. at 18

“Regarding spatial diversity, Dou explains that a first internal antenna and a second internal antenna “may be separated by a distance (D) that is no less than the quarter wavelength (>=λ/4) of the lowest frequency.” Ex. 1013 ¶ 24; see Ex. 2010 ¶¶ 35, 44. Consistent with Dou’s preference for at least a quarter-wavelength spacing between antennas at the lowest frequency, “a commonly accepted rule of thumb is that at least a quarter-wavelength spacing between antennas is necessary to provide effective spatial diversity.” Ex. 2010 ¶¶ 33, 35, 47. Effective spatial diversity requires sufficient spacing between antennas because that technique “uses multiple antennas to improve signal reliability and performance by mitigating the effects of multipath fading and other interference.” Ex. 2010 ¶ 33. “Multipath fading occurs when a wireless signal propagates along multiple different paths of differing lengths because of interactions with obstacles, resulting in portions of the signal energy arriving at a receiver with different phases slightly offset in time.” Id. Locations insufficiently separated in terms of wavelength “tend to experience similar fading and interference characteristics.” Id. Thus, closely spaced antennas “cannot provide effective spatial diversity.” Id. By providing sufficient spacing between antennas, however, “the likelihood increases that at least one of the antennas will be positioned at a location where the multipath or other interference is relatively low, thereby improving overall signal quality and reliability.” Id. As Patent Owner contends, the proposed combination modifies Dou’s ground plane 310 to replicate Jing’s ground plane with dimensions of 36 mm × 60 mm and limits “the extent of Dou’s ground plane 310 so that it [does] not extend behind Jing’s antenna at 306, just like Dou does not extend it behind antenna 308.” See Pet. 35–36; Prelim. Resp. 20 (quoting Pet. 35); Prelim. Sur-reply 1; Ex. 1007 ¶ 120; Ex. 2010 ¶ 45. The lowest frequency of Jing’s antenna is 900 MHz. Ex. 1011, 2657–58; see Ex. 1007 ¶¶ 118, 154; Ex. 2010 ¶¶ 37, 44. The wavelength (λ) corresponding to a frequency of 900 MHz is 333.3 mm, and a quarter wavelength (λ/4) is 83.3 mm. Ex. 2010 ¶ 44.

Li identifies these mechanical connectors as alternatives to adhesive bonding and “fasteners such as screws.” Id. ¶ 44; see id. ¶ 59 (identifying plugs as alternatives to “screw fixation”).

“identify areas that need replacing, such as ‘a margin line’ to be removed, ‘areas of poor margin preparation,’ and ‘holes or areas of incomplete scan[s],’” and that the user can identify regions of a prepared tooth surface requiring additional preparations and “supplemental scanning” (Pet. 32 (citing Ex. 1004 ¶¶ 189, 193, 196)), Boerjes is silent with respect to replacing at least a portion of the removed surface portion of the model using the received second scan data of the patient’s teeth, per claim 1. Boerjes certainly contemplates the re-scanning of the dentition, but does not assert partial insertion of new data into an existing 3D model. Even under the “comprising” language of claim 1, for example, the complete replacement of a 3D model cannot teach or suggest “replacing at least a portion of the removed surface portion” without repudiating the language of the claim by making a portion be the entire model. Even if, as Petitioner asserts, “removing portions of a virtual model has been a well-known and routine technique in 3D modeling,” and the “process of replacing a user-identified portion would have been well within the skills of a POSITA” (Pet. 35), the disclosure of Boerjes does not teach or suggest such processes. Although Boerjes allows for the possibility that portions of a model can be identified as needing replacement or supplementation, it does not disclose the partial replacement required by the instant, independent claims. Boerjes’s actual disclosure details that supplemental scanning is used to compensate for an inadequate scan, but not disclosed to be used to stitch together before-and-after models that have undergone an intervening physical change. slip op. at 18

“with Chishti-876’s purported teaching away and disparagement, we note again that “round-tripping” is defined in the Specification as “the technique of moving a first tooth out of the path of a second tooth, and once the second tooth has moved sufficiently, moving the first tooth back to its previous position before proceeding to a desired final position of that first tooth.” Ex. 1001, 13:8–12. Chishti-876 teaches that its “path scheduling algorithm determines the treatment path while avoiding ‘round-tripping,’ i.e., while avoiding moving a tooth along a distance greater than absolutely necessary to straighten the teeth. Such motion is highly undesirable, and has potential negative effects on the patient.” Ex. 1005, 14:46–51. The Petition does not expressly address this teaching in Chishti-876, nor does it address the prior Board finding in the ’444 IPR, in which the Board recognized that this teaching constitutes a teaching away from round-tripping. See Ex. 1008, 11– 12. On this record, it appears that Chishti-876 teaches away from “moving a tooth along a distance greater than absolutely necessary to straighten the teeth.” In short, Chishti-876 disparages “moving a tooth along a distance greater than absolutely necessary to straighten the teeth” (Ex. 1005, 14:46– 51) which is a broad statement that appears to encompass the more specific round-tripping movement taught in Becker. Petitioner itself concedes that “indirect movement was understood to be avoided if possible.” Pet. 17. Although Petitioner attempts to characterize indirect movement or round-tripping as a preferable or necessary option (see, e.g., Pet. 15–17), these arguments are insufficiently supported on this record.” slip op. at 27

Petitioner argues that, “[b]ecause the Petition is substantively identical to the Mobileye Petition, with the same grounds challenging the same claims as instituted by the Board, there are no new issues for Patent Owner to address” and, therefore, joinder with the Mobileye IPR would “not unduly burden or negatively impact the trial schedule in any meaningful way.” Id. at 6.

Petitioner contends that Nakamura teaches the user’s manual selection of a starting point of a game.

Petitioner further contends that “[a] POSITA would have also recognized that the initial position setting provides a location reference for gameplay.” Id. at 63. For this Ground 2, Patent Owner incorporates by reference its arguments regarding Ground 1 based on Cheok, Nakamura, and Foxlin077. See Prelim. Resp. 29. Patent Owner argues that “Nakamura’s position icon 113 [displayed at a virtual location appropriate for the initial position] represents a virtual character’s virtual location in the virtual world, rather than a user’s physical location, and has no relationship to the physical location.” Prelim.
