  • 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

    “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.

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.

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

    “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.

    “The expert provides no citation for his “smooth seam” rationale. Moreover, Petitioner’s expert, who has extensive knowledge in CAD drawing systems (e.g., id. ¶ 3), does not indicate that he has expertise regarding clothing, let alone seam formation on clothing. Ex. 1003 ¶¶ 3–13. As our Rules make clear, “[e]xpert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.” 37 C.F.R. § 42.65(a); see also Sundance, Inc. v. DeMonte Fab. Ltd., 550 F.3d 1356, 1363 (Fed. Cir. 2008) (“Testimony proffered by a witness lacking the relevant technical expertise fails the standard of admissibility under Fed. R. Evid. 702.”). Petitioner’s expert does not cite evidence in support of his statement, nor does he provide evidence that he has a background that indicates that he would intrinsically know such things to be true. On this record, we afford Petitioner’s expert’s testimony on the “smooth seam” rationale no weight. For this reason, Petitioner’s obviousness position is untenable. In re Kahn, 441 F.3d 977, 988 (Fed.

    “asserts that it would have been obvious to add these features from Niterra’s circuit board designer into the clothing designer of EZBRUSH. Pet. 45–50. Petitioner asserts that the reason to do so is because “it would have been desirable to select the sewing segments to be equal in length when seeking a clean, smooth seam that prevents bunching or unintended stretching of the material.” Id. at 45 (citing Ex. 1003 ¶ 64). Petitioner then goes on to explain various benefits from adding these “smooth seam” features. Id. at 46–50. Patent Owner argues that “[Petitioner’s] rationale is completely rooted in hindsight” because nothing in the prior art describes a desire to seek a smooth seam. Prelim. Resp. 69. Turning back to the Petition, we see that Petitioner’s “smooth seam” rationale is underpinned by a citation to its expert declaration. Pet. 45 (citing Ex. 1003 ¶ 64). The expert, in turn, repeats the language from the Petition, but provides no explanation as to the underlying facts or data on which his opinion is based. He states: A [person of ordinary skill in the art] would have known that when using the resulting CAD system (EZBRUSH as modified by Corel and Thoemmes (detailed above)) to digitally “sew” two garment patterns together, selecting the sewing segments to be equal in length would have been desirable when seeking a clean, smooth seam that prevents bunching or unintended stretching of the material.

    “First, Petitioner has not sufficiently shown that either Grinspun or Graphicxtras teach taking measurements “of” a two-dimensional pattern, as described in the preamble of claim 1. See Prelim. Resp. 20–23. Grinspun provides a 2D pattern in its Design Window 110, but does not measure any part of the 2D pattern. Id. at 20; Ex. 1004 at 17, 37–38, Fig. 1; see also Ex. 2001 ¶¶ 76–77 (Govindaraj Decl.). Graphicxtras teaches taking horizontal or vertical measurements between bounding boxes, but does not measure the distance between the actual outlines of the pattern pieces. Ex. 1005 (Graphicxtras); see Ex. 2001 ¶¶ 79–81. Even if the preamble is not considered to be limiting, the fact remains that neither reference discloses measuring a distance within a pattern piece, which is required by the claim language “determining a length of a line segment using the points . . . responsive to determining that the points are located in different pattern pieces[.]” Ex. 1001 at 18:3–4 (emphasis added); see Ex. 2001 ¶¶ 84–85. Second, Petitioner has not shown that either reference, alone or in combination, can determine whether two points are on the same pattern piece or different pattern pieces by affirmatively examining “attributes of areas” in which the points are located. Prelim. Resp. 27–29 (citing Ex. 2001 ¶¶ 87–90). The ’448 Specification indicates that a “measuring apparatus may determine that areas to which the two points A and B belong correspond to different pattern pieces based on the data structure corresponding to each of the two points A and B.” Ex. 1001 at 7:25–40. The data structure corresponding to each of the points may store information corresponding to each of the points in the form of a linked list, a tree, or a table, for example. The information corresponding to each of the points may include, for example, identification information of a pattern piece in which each of the points is positioned, identification of a line in a pattern piece in which each of the points is positioned, a coordinate of a point on a line of a pattern piece, and the like. Id. at 6:63–7:4. This is reflected in claim 1, which contains the limitation “determining a length of a line segment using the points based on the determined attributes of the areas, the determined length of the line segment changed to account for separation between the pattern pieces responsive to determining that the points are located in different pattern pieces[.]” Ex. 1001 at 17:66–18:4. The Grinspun-Graphicxtras combination does not do this. Rather, in the proposed combination the two points A and B are always on the edges of two different pattern pieces, and there is no disclosure of a set of data structures that would enable the proposed software to determine the location of the points in relation to the 2D pattern pieces depicted. Prelim. Resp. 27–29 (citing Ex. 2001 ¶ 90); see Pet. 35 (annotating Figure 1 of Ex. 1004). Third, because the line segment in the proposed combination is always between the edges of two different pattern pieces, the combination does not determine the “length of a line segment using the points based on the determined attributes of the areas” associated with the two points. Prelim. Resp. 41–42 (citing Ex. 2001 ¶¶ 91–93); Ex. 1001 at 17:62–65 (emphasis added); see also Pet. 40, 42, 44 (further annotating Figure 1 of Ex. 1004). Fourth, Petitioner misinterprets the claim language “the determined length of the line segment changed to account for separation between the pattern pieces” and does not does not even address the remainder of that claim element, “responsive to determining that the points are located in different pattern pieces.” See Ex. 1001 at 18:1–4 (emphasis added). This language does not mean that the user manually changes the length of the line segment by moving the pattern pieces. See Pet. 40–44. It means that the portion of the line segment that is in the empty space between the pattern pieces is subtracted, as shown in Figure 4 of the ’448 Patent, in order to determine the measurement of a portion of the 3D clothing to be created from the 2D pattern. Prelim. Resp. 40–41 (citing Ex. 2001 ¶¶ 94–95). We agree with and adopt the explanation of Patent Owner’s expert declarant, Dr. Govindaraj that: [T]he ’448 teaches repeatedly and the claims require that the patterns are fixed relative to one another, that the selected points are fixed, and that the line segments are fixed. The entire purpose of the claimed invention is to measure the length of a line segment in response to determining that the points are located in different pattern pieces, and then accounting for the “white space” or “separation between” the two patterns.

    “We agree with Patent Owner. Petitioner does not explain or address sufficiently how Nakamura performs current modulation. Although Nakamura discloses modulating the carrier wave transmitted from the power transmission apparatus 1 and transmitting that modulated wave (the “information signal”) to primary side coil 11 (e.g., Ex. 1005 ¶¶ 77, 78, 80), we find persuasive Patent Owner’s arguments that Petitioner has not established that this discloses modulating the power transfer current induced by the base unit. See Prelim. Resp. 18–22. Petitioner cites to testimony from Dr. Baker that the “information signals (which have current) are modulated . . .” (Ex. 1002 ¶ 215), but this testimony does not establish current modulation. That is, simply because the information signals may have current fails to establish that current modulation is performed as recited in the claim. Therefore, on this record, we are not persuaded that Petitioner has sufficiently shown that Nakamura alone teaches this limitation for purposes of institution.” slip op. at 17
