Ex. 1001, 5:44–59. Petitioner and Dr. Osswald provide significant evidence and reasoning tending to show that Porter’s discussion of Tritan logically would have commended itself to the attention of an inventor facing the problem of selecting an aligner hard layer.

To create the laminated multilayer aligner proposed, Petitioner’s suggested use of a particular type of well-known lamination, i.e. adhesive lamination, is sufficiently developed and supported in the Petition.

“the meaning of the claim term “mode” as it is used in the ’848 patent and as one of ordinary skill in the art would understand it at the time of the invention. First, the parties do not necessarily disagree as to the meaning of the term “mode.” Patent Owner asserts that a person of ordinary skill in the art “would understand ‘mode’ to mean “an operational state that a system has been switched to.” PO Resp. 13. Petitioner “do[es] not necessarily object to the concept of a ‘mode’ as an operational state,” but does object to how Patent Owner applies the term. Pet. Reply 1. Petitioner objects to Patent Owner’s “application of its construction,” which, Petitioner argues, “is far narrower than the words alone suggest.” Id. Second, the intrinsic evidence, including the claims and the ’848 specification, makes it readily apparent what the ordinary and customary meaning of the term “mode” would be to one of ordinary skill in the art at the time of the invention. Based upon our consideration of the claims and the ’848 specification, we find that the term “mode,” as it is used by the ’848 patent, means a “state,” “condition,” or “operational state” of a recording device, such as a video camera, that is selected by a user and may include a selection function using threshold values.” slip op. at 19

“Here, Petitioner provides a persuasive rationale as to why a person of ordinary skill in the art would combine the teachings of Nozaki, Haitani, and Graham as described in the Petition.

“record, we are persuaded that the results recited in claim 1 would follow from the steps taught in the MSR, for the reasons and based on the evidence Petitioner cites above. For these same reasons, we are unpersuaded by Patent Owner’s argument that it was unknown whether the amount of pembrolizumab recited in claim 1 would be effective in producing an improved outcome compared to a reference patient without a tumor that was not MSI-H or dMMR, and Patent Owner does not dispute that the amount of pembrolizumab disclosed in the MSR (10 mg/kg every 14 days; see Ex. 1005, 4) is the same as the amount provided in the ’975 patent as being effective (10 mg/kg every 14 days; Ex. 1001, 8:48–52, 13:50–52). Regardless of the inventors’ intent in publishing the MSR as a Stage II clinical trial on the www.clinicaltrials.gov website, as discussed above, we determine that the MSR teaches selecting a patient with a metastatic MSI-H or dMMR tumor and administering an amount of pembrolizumab that would be effective. See, e.g., Ex. 1005, 4 (Arms and Interventions). The result of drug treatment inherently follows its administration. The MSR does not merely suggest that pembrolizumab may be useful in some unidentified subset of patients or suggest that some unidentified drug may be useful for MSI-H cancer patients. Instead, the MSR discloses selecting a patient with a condition recited in claim 1 and treating with the drug at the amount recited in claim 1. Contra Metabolite Labs. Inc. v. Lab. Corp. of Am. Holdings, 370 F.3d 1354, 1367 (Fed.

Patent Owner attempts to distinguish the size and apparent surety of the study in Montgomery from the MSR. PO Resp. 15. But because we find that the MSR teaches performing the steps recited in claim 1 for the purpose of determining and treating MSI-H cancer, we are persuaded that the MSR inherently discloses the results of selection of patients and administration of the drug treatment recited in those steps. See Bristol-Myers, 246 F.3d at 1376. Whether or not the MSR could have provided results or was sufficient for full regulatory approval does not change that the MSR teaches Patent Owner’s claimed steps. We have no reason to doubt that the disclosure in the MSR of the steps recited in claim 1 produces the efficacy element required in claim 1, whether or not this efficacy was disclosed in the MSR or was known when it was published.

“use that does not qualify as prior art. PO Resp. 18–25. Patent Owner argues that an inventor can be granted latitude to experiment in the public eye until her invention is ready for patenting. Id. at 18 (citing Pfaff v. Wells Elecs., Inc., 525 U.S. 55, 64 (1998). According to Patent Owner, the experimental use negation applies to the MSR under a 13-factor analysis provided in Allen Engineering Corp. v. Bartell Industries, Inc., 299 F.3d 1336, 1353 (Fed. Cir. 2002). PO Resp. 19–25.

Patent Owner argues that “[a]t the time of the MSR’s posting, the claimed invention was not, nor could it have been, ready for patenting. The clinical study that ultimately collected the data reported in the patent specification and supporting the patent claims had not and could not have commenced before the MSR was posted.” Id. at 23. sometimes said that an inventor acquires an undue advantage over the public by delaying to take out a patent, inasmuch as he thereby preserves the monopoly to himself for a longer period than is allowed by the policy of the law,” but held that “when the delay is occasioned by a bona fide effort to bring his invention to perfection, or to ascertain whether it will answer the purpose intended,” the experiment use exception can preserve the inventor’s rights. City of Elizabeth v. Am. Nicholson Pavement Co., 97 U.S. 126, 137 (1877). Because we are not persuaded that Patent Owner could not have filed an earlier application, we are not persuaded that the experimental use doctrine is properly applied in this case. Given that clinical trial protocols published on the ClinicalTrials.gov website have been successfully asserted as prior art in other cases, we are not persuaded by Patent Owner’s arguments that the MSR is not available as prior art against the challenged claims.

“Putting aside the controversy over alleged impropriety and sandbagging in connection with the District Court’s Order, which we address infra in connection with Patent Owner’s Motion to Strike, we find the District Court’s “mirror-mimicking” construction to be well-reasoned and supported by the record, and we therefore adopt that construction and its reasoning. As the District Court points out, both the “double the distance” and “same size” aspects of its construction are expressly discussed in the ’109 patent. See Ex. 2008, 16 (citing Ex. 1001, 2:5–27, Figs. 5A, 5B). So, too, is “flipping” or reversing of the image disclosed. Id. at 17 (citing Ex. 1001, 14:46–51, 15:41–47). Petitioner does not dispute that the ’109 patent discloses these aspects of “mirror-mimicking,” or even that the District Court’s claim construction is incorrect. Instead, Petitioner contends that “[t]he Board need not construe ‘mirror mimicking’ [beyond plain meaning] since the prior art expressly discloses mimicking a mirror.” Pet. Reply 6. Further. Petitioner characterizes the claim construction order as “a report and recommendation” by a magistrate judge that “the district court judge has not evaluated or adopted.” Id. at 6 n.2.9 We address infra whether the prior art “expressly” discloses “mirror- mimicking” as construed by the District Court. We, however, disagree with Petitioner that we should not construe this term. Given the controversy over whether Petitioner has argued for a different construction in the District Court, we cannot agree that an explicit construction of “mirror-mimicking” is an unnecessary step toward resolving this controversy.

“We do not agree. Petitioner demonstrates persuasively that a person of ordinary skill would have combined these references “to reduce distortion and provide a realistic mirror image.” Pet. 14–17; Haram Decl. ¶¶ 110–117. We are not persuaded by Patent Owner that by specifically disclosing “flipping” the image, Rosenberg is discouraging or teaching away from performing other transformations to achieve its objective of “replicat[ing] the performance of a standard household mirror.” See PO Resp. 32–33 (Patent Owner asserting lack of motivation to combine the references). A reference may be said to “teach away” “when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” Galderma Lab'ys, L.P. v. Tolmar, Inc., 737 F.3d 731, 738 (Fed.

“We find that Petitioner has not demonstrated by a preponderance of evidence that step 1(h) is taught or suggested by the references cited by Petitioner or the testimony of Petitioner’s expert, Dr. Karam. We agree, instead, with Patent Owner’s argument that “a [person of ordinary skill] would regard the disclosures in Rosenberg relating to proximity detection to be in connection with turning on or off various display modes and not in connection with varying the rate of one or more steps that are performed to transform a series of captured images of a user.” PO Resp. 33 (citing Ex.1005, ¶¶ 25, 32, 56, 69, 114). This distinction was explored during the final hearing. Petitioner’s counsel confirmed that in Rosenberg’s mirror mode, the rate of performing the processing steps does not vary: [THE BOARD]: It’s true that when the -- when Rosenberg is acting in the mirror mode, it’s always at the same rate, correct? It’s always performing those three processing steps at the same rate? [COUNSEL]: Correct. Hearing Tr. 34:13–16. We conclude that Rosenberg fails to disclose or suggest step 1(h) for the reasons given by Patent Owner and summarized above. We agree with Patent Owner’s analysis that in Rosenberg, when the mirror is off the processing steps are not performed, and when the mirror is on, the steps are performed “at an invariant rate.” PO Sur-reply 18–19.” slip op. at 33

“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
