“generally known in the art, and that this is acknowledged by the ’853 patent. Pet. 40–41 (citing, e.g., Ex. 1001, 15:40–44). Petitioner asserts that Kouzani touts the benefits of fractal models and that it would have been obvious to use Kouzani’s fractal model as the object model in Zhou. Pet 44 (asserting that “[a] person of ordinary skill would have therefore been motivated to implement Kouzani’s techniques in Zhao’s system”); see also id. 42–45. (entire argument). Patent Owner argues that Kouzani’s fractals would not result in the claimed limitation. Prelim. Resp. 21–23. In particular, Patent Owner points out that Kouzani’s fractals use a block-based fractal system, which do not include “a representation of the object based on landmarks associated with the object” as required by claim 1. Id. at 21–22. Patent Owner’s argument is persuasive. Even if Kouzani teaches fractals, claim 1 is not broadly claiming any fractal, but rather one that is “based on landmarks” (e.g., eyes, nose, etc.). See Ex. 1001, 13:53–57. The block-based system of Kouzani is based on abstract, repeated patterns of pixels, without regard to what the pixels represent. See, e.g., Ex. 1006, 8 (describing a “search . . . through the domain pool to find a domain block whose contractive transformation best approximates the range block” and then storing all of the transformations that, together, “represent the compressed image of a person’s face”), Fig. 4 (showing example blocks). This is in contrast to looking for particular landmarks in the image. Thus, we find that Petitioner has not sufficiently established that Kouzani’s fractal is based on landmarks. In Petitioner’s ground, Petitioner asserts that Zhao already teaches the claimed landmarks (Pet. 39, citing Ex. 1003 ¶¶ 58, 65), but Petitioner’s ground replaces or modifies the object model of Zhao with the fractals of Kouzani, which are not based on landmarks. Petitioner does not explain how Zhao’s modified model, now using a block-based fractal system, would still have the landmarks of Zhao’s original model. Even if it were obvious to include fractals, we are persuaded that the fractals included by Kouzani are not based on landmarks. Alternatively, if Petitioner is asserting merely to use fractals in Zhao’s models, then Petitioner has not sufficiently accounted for the particular fractals claimed and explained persuasively how merely using fractals in Zhao would lead to the claimed subject matter, i.e., fractals based on landmarks. In either event, Petitioner has not sufficiently established that the proposed combination satisfies the “fractal includes a representation of the object based on landmarks” limitation of claim 1.” slip op. at 11

Reason to reduce contaminant levels We agree with Patent Owner that Petitioner identifies no teaching in the prior art providing any reason to reduce levels of 6,7-dimethoxy-quinoline-4-ol specifically. And while Brown does teach a desire to form “substantially pure” compounds, Brown focuses on “at least about 90 wt.%” of the compound, then lists specifically “about 90, about 91, about 92, about 93, about 94, about 95, about 96, about 97, about 98, about 99 and about 100% wt. %.” Ex. 1003 ¶ 97.

But even with that combination, Dr. Dichtel states only that a “POSA would have expected there to be a decrease in the amount of 6,7- dimethoxy-quinoline-4-ol at the end of cabozantinib (L)-malate’s synthesis that was attributable to hydrolytic degradation of the 4- (nitrophenoxy)quinoline intermediate by avoiding its use in the synthesis.” Id. ¶ 78. That is not, however, the standard for inherency. It must be the necessary result, not a possible expected result. The Federal Circuit in Par explained that: Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient. If, however, the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be regarded as sufficient.” slip op. at 28

Ex. 1004, 181.8 In making the amendment, Applicant stated that the language added by amendment was intended to distinguish the pending claims over Uniyal,9 which Applicant characterized as disclosing a “time series” of ultrasound data. Uniyal relies on a time series of ultrasound data. In order to distinguish Uniyal, the claims have been amended to recite a single static set of ultrasound RF data in a single frame of the tissue area. As explained in the Interview, the claims rely on a signle [sic, single] “snapshot” frame of the ultrasound RF data rather than a time series or [sic, of] RF data as disclosed in Uniyal.

“agree with Patent Owner that Petitioner has not sufficiently shown for institution that Bansal teaches or suggests arranging light sources “such that a higher intensity of light is emitted proximate the second edges compared to the intensity of light emitted not proximate the second edges,” as required by the challenged claims. Instead, Petitioner demonstrates how Bansal describes varying the density of light source distribution throughout the array to provide a higher density of light in the entire peripheral area of the array, which includes the areas proximal to both the first and second edges, as compared to the central area of the array. See Pet. 36–37; Ex. 1005 ¶ 25. In this regard, Petitioner relies on Bansal’s Figure 9b, asserting that it “shows one embodiment where more light sources are placed near the edges of the panel compared to the light sources in the center.” Pet. 36–37.

What is missing from Petitioner’s argument and discussion of Bansal is how Bansal teaches or suggests a configuration that provides a higher density of light proximate to the second shorter edges of the periphery in comparison to the remaining areas of the array, which includes the first longer edges of the periphery. Without that discussion, we find that Petitioner has not shown sufficient for institution that Bansal is persuasively relied upon for the light source arrangement limitation of the challenged claims. likelihood of prevailing in its obviousness challenge of independent claims 1, 5, 16, 20, or 21, or dependent claims 2, 4, 6–8, and 17–19 over Larsen, Bansal, and Jones.” slip op. at 17

“When determining whether to exercise discretion to deny institution in view of a parallel proceeding, we consider the following factors: 1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits.

“For the reasons set forth above, and even if we consider Petitioner’s proposed rationale for combining Ingale and Jung to be supported by sufficient rational underpinnings (see e.g., Pet. 24–27), neither Jung nor Ingale, either individually or in the proposed combination set forth by Petitioner teach or suggest limitation 9.6 of claim 9 so as to rise to a compelling, meritorious showing for claim 9. 4. Remaining Claims Petitioner’s arguments and evidence for independent claim 13 (Pet. 58–59) and dependent claims 10–12 and 14–16 (id. at 51–57, 59–60) are substantially similar to Petitioner’s arguments and evidence for claim 9 and are unopposed at this stage by Patent Owner (except for the issues discussed above with respect to independent claim 9) (see e.g., Prelim.

“II. ANALYSIS A. Legal Standards Used in the Merits Analysis “In an IPR, 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 grounds for the challenge to each claim”)); Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). A claim is unpatentable under 35 U.S.C. § 103 if “the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious . . . 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 skill in the art; and (4) when in evidence, objective evidence of non-obviousness, i.e., secondary considerations.

Similarly, Petitioner asserts that adding “TUKATECH’s suggested techniques” to EZBRUSH “would be merely the application of known techniques to a known system ready for improvement to yield predictable results.” Pet. 43 (citing Ex. 1003 ¶ 62). Petitioner asserts that a person of ordinary skill in the art “would have recognized that applying the suggested user interface improvement from TUKATECH to EZBRUSH’s CAD system would have led to predictable and helpful results with a reasonable expectation of success.” Id. (citing Ex. 1003 ¶ 62). Similar to the discussion above, we have reviewed the cited paragraph of Petitioner’s expert’s declaration and find insufficient credible evidence supporting Petitioner’s naked assertions regarding what was an “application of known techniques to a known system ready for improvement to yield predictable results.” Pet. 43; Ex. 1003 ¶ 62. To the extent Petitioner is arguing that obviousness can be established merely by showing that EZBRUSH and TUKATECH are in the same field of endeavor (e.g., Pet. 43 (“both [are] directed toward CAD systems”)), we disagree. We are not aware of any authority supporting such an argument. Petitioner has not sufficiently explained why or how it would have been obvious to apply the length comparison information from the table of TUKATECH’s size reshaping feature to EZBRUSH in a manner that meets each step of the claim. Thus, Petitioner’s additional reasons for modifying EZBRUSH to implement TUKATECH’s sizing table are also untenable.” slip op. at 10
