  • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

    “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

Moreover, Petitioner does not even assert that one of ordinary skill in the art would have recognized that Schwartz cross-correlates one or more product facing bounding boxes and one or more other product facing bounding boxes as required by limitation [1.5]. Instead, Petitioner asserts only that one of ordinary skill in the art “would have recognized Schwartz . . . cross-correlates that product and affiliated shelf added).

    “Furthermore, we are not persuaded that modifying Aksu in view of Gonzalez in the manner proposed by Petitioner overcomes this problem. As noted above, Petitioner asserts that, in the proposed combination, one of ordinary skill in the art “would have understood that the Laplacian’s output would be compared directly to a threshold based on β—just like Aksu’s difference calculations—to determine how many pixels to filter.” Pet. 60 (citing Ex. 1019, 13:15–19; Ex. 1003 ¶¶ 406–410). We disagree with this assertion, however, because it relies on erroneously equating the output of calculations (i.e., |r1-rj| and |r1-ri+1|). In other words, Aksu’s difference calculations, although used in setting dr, are not the same as dr; and we are not persuaded that one of ordinary skill in the art would have considered comparing Gonzalez’s Laplacian output to threshold β because Aksu discloses comparing its difference calculations to β. As noted above, we are not directed to any disclosure in Aksu of comparing dr to β. In addition, Dr. Schonfeld’s testimony on this point is not persuasive. Specifically, Dr. Schonfeld testifies that “dr can simply be defined as the output of the Laplacian (dr=|r3-2r2+r1|), and dr could be directly compared to a threshold based on β.” Ex. 1003 ¶ 408 (underline emphasis added). This testimony, however, is entitled to little weight because Dr. Schonfeld fails to provide a sufficient underlying basis for his opinion. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Nobel Biocare Services AG v. Instradent USA, Inc., 903 F.3d 1365, 1382 (Fed. Cir. 2018) (explaining that the Board can reject arguments based on expert testimony that lacks specificity or detail). Moreover, opining that output of the Laplacian, dr, could be directly compared to β does not establish sufficiently that one of ordinary skill in the art would have been motivated to do so. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed.

But Dr. Schonfeld does not explain adequately how the cited portions of Gonzalez disclose that the coefficients were known to control the frequency response in a deblocking filter. Indeed, the cited portions of Gonzalez do not appear to discuss determining offsets for deblocking filtering or the coefficients used in an equation for determining offset. See Ex. 1020, 153, 273.

    “claim element creates a rebuttable presumption that § 112[(f)] applies” and that “the failure to use the word ‘means’ also creates a rebuttable presumption—this time that § 112[(f)] does not apply.”12 Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc in relevant part) (internal citations omitted). Because the “sealing means” limitation includes the word “means,” we start from the rebuttable presumption that § 112(f) applies. Petitioner does not address the applicability of § 112(f) and does not rebut the presumption. We continue the analysis, however, and, for the reasons below, we agree with Patent Owner that § 112(f) applies to the “sealing means” limitation.” slip op. at 12

    “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
