“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

“c) Summary We may institute an inter partes review when “the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). We have determined that, at this stage of the proceeding and on the present record, the information presented in the Petition does not show that Petitioner is reasonably likely to prevail with respect to its challenge to claim 1 based on the combination of Elliott and Jacob. Specifically, the Petition does not demonstrate that the proposed Elliott/Jacob combination would teach or suggest either limitation [1.e] or limitation [1.a] of independent claim 1. For the same reasons, the Elliott/Jacob combination does not teach or suggest the commensurate limitations in independent claims 6 and 11.

That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006. 2. Conclusion: PGR Eligibility For the foregoing reasons, and based on the record before us, we determine that Petitioner has not demonstrated that it is more likely than not that the ’202 patent has, or had, at least one claim having an effective filing date on or after March 16, 2013. Accordingly, we determine that the ’202 patent is entitled to the filing date of the ’634 application (October 18, 2006), and, thus, the ’202 patent is not eligible for post-grant review.” slip op. at 18

“Accordingly, the ’202 patent consistently and repeatedly characterizes the invention as incorporating tobacco in some form and ties the stated benefits of the invention to the inclusion of tobacco. Moreover, the Specification is directed to smoking articles containing tobacco, all of the embodiments include tobacco, and “the present invention” is described as a smoking article, where the smoking article includes tobacco. Consequently, we determine that “smoking article” as it is used in the challenged claims is limited to devices that include tobacco. See Mosaic Brands, Inc. v. Ridge Wallet LLC, 55 F.4th 1354, 1361 (Fed. Cir. 2022) (finding claimed “lip” is limited to “extrudable plastic materials” where specification states that “the device of the present invention is constructed of extrudable plastic materials” and “emphasizes the benefits of using extrudable plastics and describes them as benefits of the invention as a whole”); Poly-Am., L.P. v. described in the specification has inwardly extended short seals and every section of the specification indicates the importance of inwardly extended short seals. These two facts provide together a proper reason to limit the claims in this way.”); Phillips v. AWH Corp., 415 F.3d 1303, 1312–1317 (Fed. Cir. 2005) (en banc) (“[T]he specification may reveal an intentional disclaimer, or disavowal, of claim scope by the inventor. In that instance as well, the inventor has dictated the correct claim scope, and the inventor’s intention, as expressed in the specification, is regarded as dispositive.”).” slip op. at 13

“Petitioner’s argument is dependent on accepting Petitioner’s assertion that the claims include a smoking article that does not contain tobacco, which we have not done. Instead, as set forth above, we construe “smoking article” as being limited to devices that include tobacco. See § II.B.2, supra. Based on our construction of “smoking article” and the evidence of record in this proceeding, we determine that the challenged claims are supported by the specification of the ’202 patent, which is identical to the specification of all of the continuations in the chain leading back to the October 18, 2006 that the specification of the ’202 patent and every patent in its priority chain “have identical specifications”); Prelim. Resp. 13 (noting that Petitioner does not identify other limitations in the challenged claims “allegedly lacking support in the ’202 patent family’s applications dating back to U.S. App. No. 11/550,634, filed on October 18, 2006”). Accordingly, we determine that Petitioner does not demonstrate that it is more likely than not that the challenged claims lack written support in the Specification (and the ’634 application). That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006.” slip op. at 17

“An obviousness determination requires finding both ‘that a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.’” CRFD Research, Inc. v.

“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. The comparison of Bansal’s light density between the entire periphery and the central area of the array is insufficient. 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

“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
