“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

“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. 35 U.S.C. § 103(a); see also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved based on 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) any objective indicia of nonobviousness.7 Graham v.

“tripping” as “any motion of a tooth in any direction other than directly toward the desired final position.” Ex. 1004, 4:12–13. Chishti-511 teaches minimizing round-tripping (“teeth are moved in the quickest fashion with the least amount of round-tripping”), but acknowledges that “[r]ound-tripping is sometimes necessary to allow teeth to move past each other.” Id. at 4:9–15. In an attempt to counter Patent Owner’s teaching away arguments, Petitioner relies heavily on Chishti-511’s statement that “[r]ound[-]tripping is sometimes necessary.” See Pet. 29–30; see also Ex. 1003 ¶ 83 (Dr. Yadav relying on Chishti-511). This reliance is unavailing, because as noted above, Chishti-511 defines “round-tripping” more broadly than is claimed here. Indeed, in the ’444 IPR, the Board stated that “the ‘round tripping’ described in Chishti ’511 is something different than the ‘round tripping’ required by the ’444 patent.”10 Ex. 1008, 16. Despite being aware of this prior finding 10 In the ’444 IPR, the Board employed the same construction of “round-tripping” that we use here. Compare Ex. 1008, 6, with Section II.C supra. (see Pet. 6), Petitioner here fails to address the difference between Chishti- 511’s round-tripping and the claimed round-tripping. That is, Petitioner places great weight on Chishti-511’s statement that “round-tripping is sometimes necessary,” but has not established that Chishti-511 contemplates round-tripping as claimed, as opposed to some other, different movement pattern encompassed by Chishti-511’s broader statement about round-tripping.” slip op. at 21

“discussion of “need[ing] collision-free treatment paths,” skilled artisans would have turned to Becker. Pet. 23–24 (citing Ex. 1004, 4:15–22). But on this record, and especially in view of the teachings away from round-tripping, Petitioner does not demonstrate a reasonable likelihood that a skilled artisan would have combined Becker’s movement pattern with the Chishti systems and Sachdeva. In particular, the Petition and supporting materials lack sufficient argument and evidence for us to conclude that a person of ordinary skill in the art would have had reason to apply Becker’s movement pattern in the context of an aligner treatment. Becker is a textbook relating to the orthodontic treatment of impacted teeth. Ex. 1006, 1 (Title). Patent Owner correctly states that “Becker is a different orthodontic treatment modality compared to the Chishti references,” using “braces and numerous brackets, wires, and rubber bands, with the wire-and-bracket systems being attached directly and permanently to the teeth.” Prelim. Resp. 21–22; see also supra Section II.D.4. “Becker involves traditional orthodontic practice: manual, by-eye adjustment of its archwires, elastic thread, and palatal wires by a treating orthodontist in repeated office visits.” Prelim. Resp. 22. Chishti-511, in contrast, uses “treatment planning software” to “pre-stag[e] a series of tooth positions from which a sequence of appliances can be manufactured.” Id. On this record, we agree with Patent Owner that “Becker at best shows that round-tripping was an option in limited circumstances involving wire-and-bracket treatment.” See Prelim. Resp. 3. Petitioner does not direct us to any persuasive evidence that using aligners to effect Becker’s tooth transposition “would be appropriate or even possible.” Id. at 22. As Patent Owner correctly notes, Petitioner does not point to any teaching in Becker regarding aligner treatment or corresponding treatment planning software. Id. at 23. Nor are we directed to any portions of Chishti-511, Chishti-876, or Sachdeva that mention using aligners to transpose teeth. These omissions are important because “[i]n contrast to treatment with braces, in which wires are manually adjusted by the orthodontist to move teeth reactively, aligner treatment involves treatment planning in which a detailed path of teeth is calculated in advance.” Id. at 4. Given these differences, Petitioner has not persuasively explained why Becker’s tooth movement pattern and mechanism would have been of interest to a skilled artisan who was” slip op. at 25

Ex. 1003 ¶ 115. This is the obvious inference a skilled artisan would have drawn from Burger’s description of authenticating the pocket vault and subsequently allowing credit card information to be used. Thus, we find that, in this example, the operator of network server 114 is a third party that operates a trusted authority, the principle parties to the transaction are the user of pocket vault 102 and the retailer, and a message from network server 114 to pocket vault 102 allowing the credit card to be used (displayed or encoded in the token) is an access message allowing the user access to the application (file with credit card information).

Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public.

Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

“Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

“In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve Dobashi’s RSm values. Dobashi teaches that because RSm “can be adopted as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66–3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66– 3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.

“II. STANDARD OF REVIEW When rehearing a decision on institution, we do not review the merits of the decision de novo, but instead review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion may be determined “if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors.” Arnold Partnership v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004) (citing In re 1 US 2013/0108922 A1, published May 2, 2013 (Ex. 1004, “Shinozaki”). 2 G. Khatibi, Temperature Dependent Elastic and Thermal Properties of Thin Copper Foils, Copper; Proceedings of the International Conference Copper ’06 (2006) (Ex. 1006, “Khatibi”). 3 Korean Patent Pub.

“For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE[6] value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added).” slip op. at 4

“Petitioner, however, does not adequately explain why a POSITA would have been motivated to modify Kim’s copper foil surface to have a Pc value of 19.2 as reported in Griesi. In particular, neither Petitioner nor Dr. Randall points us to, nor do we discern, any teaching in Griesi that a peak count of 19.2 provides any particular benefits or properties that would have lead a POSITA to modify Kim’s copper foil surface as Petitioner proposes. Instead, Petitioner’s arguments that a POSITA would have been motivated to modify Kim’s copper foil surface with Griesi’s peak count patent itself. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 421 (2007) (stating that the fact finder must be aware “of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning”). It was Petitioner’s burden to establish that the combined teachings Kim and Griesi disclose limitation [1g] as proposed. We are not persuaded that we misapprehended Petitioner’s argument when we determined that Petitioner did not meet that burden.” slip op. at 8
