    “We are not persuaded, on this record, that Petitioner adequately establishes that Khatibi discloses a CTE in the claimed range of 16 to 22 µm/(m·°C.). Petitioner’s argument that Khatibi’s reported values meet this claim limitation are based solely on Dr. Randall’s testimony that Khatibi’s measurement method would produce results that would not significantly differ from results determined using the claimed method. See Pet. 16–18 (citing Ex. 1003 ¶¶ 56–60). Dr. Randall’s testimony, however, is largely conclusory and unsupported by adequate explanation and/or objective evidence. For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added). to little weight.

    “second surfaces of the electrolytic copper foil ranges from 3 to 92.” Ex. 1001, 13:62–63. Petitioner contends that “Kim teaches that the electrolytic copper foil (e.g., untreated or treated copper foil) having Rz less than 2 µm is advantageous toward battery efficiency and performance,” and, similarly, Griesi describes the use of untreated electrolytic copper foil with an Rz value less than 2 µm in printed circuit boards that are compatible with secondary batteries. Pet. 58–59 (citing Ex. 1012, claim 2, ¶¶ 13, 25, 27; Ex. 1003 ¶ 157). In particular, Petitioner notes that Griesi’s Figure 3.16 describes an “Rz value of 1.2 µm.” Id. at 59 (citing Ex. 1015, 53–54; Ex. 1003 ¶ 158). Petitioner asserts that “Dr. Randall explains that a POSITA would have also recognized another surface roughness-related parameter, Rpc, in Griesi as a potentially useful parameter that can be optimized to further enhance uniformity or generally improve Kim’s copper foil surface, for example, to prevent wrinkles or achieve other advantageous effects.” Id. (citing Ex. 1003 ¶ 159). Although Dr. Randall demonstrates that Griesi’s Pc (or Rpc) value is 19.2 over a 4 mm sampling length (Ex. 1003 ¶ 155), Petitioner does not contend that Griesi addresses this value, or indicates any benefit that might be derived from its use. Instead, Griesi’s Pc value appears to be an incidental finding, which is not discussed or analyzed in the reference. See incidental, unexamined finding would lead a POSITA to import Griesi’s Pc value into Kim’s copper foil, absent a hindsight desire to reconstruct the claimed invention. As such, Petitioner’s arguments with respect to Kim and Griesi are not persuasive. See Cheese Sys. Inc. v. Tetra Pak Cheese and Powder Sys., Inc., 725 F.3d 1341, 1352 (Fed. Cir. 2013) (“Obviousness cannot be based on the hindsight combination of components selectively culled from the prior art to fit the parameters of the patented invention.” (internal quotations marks omitted)).

    “The parties agree that the proposed levels of ordinary skill in the art are “not materially different.” PO Resp. 4; Reply 2. The difference, essentially, is that Patent Owner more explicitly describes the members on the interdisciplinary team, and argues that it would be necessary to consult with such individuals, particularly with persons experienced in dentistry or orthodontics, whereas Petitioner’s proposal states that one “could” consult with such individuals. However, Patent Owner’s argument that it would be necessary for a person of ordinary skill in the art to consult with an individual having experience in dentistry and/or orthodontics is narrower than Patent Owner’s proposed level of skill in the art, which describes “individuals familiar with medical imaging, dental imaging, dentistry, and/or orthodontics.” PO Resp. 4 (emphasis omitted, emphasis added).

Ex. 1003, 7; Ex. 1002 ¶ 3. Second, Dr. Foroosh has the required work experience, with, for example, research in machine learning, deep learning, and neural networks, image and video processing and analysis, and computer vision.

Ex. 1003, 32; Ex. 1002 ¶ 12. Dr. Foroosh describes a research project, Modeling and Visualization of Muscoloskeletal Structures in Dental CT-Scan (2006–2007), where he “developed algorithms for [threedimensional (‘3D’)] registration, modeling and visualization of maxilla and mandible of patients for dental surgery using Computer Aided Tomography (CAT) scanning.” Ex. 1002 ¶ 6. He describes another project for the National Science Foundation, which “was directed to the registration/alignment of dental CT scans of patients over a period of time during the treatment of a patient, with the purpose of improving the quality of 3D models, e.g., corrections and noise removal in 3D CT scans.” Id. ¶ 7. He was also a co-author on Alignment of Maxillofacial CT Scans to Stone- Cast Models Using 3D Symmetry for Backscattering Artifact Reduction, Proceedings of Medical Image Understanding and Analysis Conference (MIUA) (2006), and an adviser for a dissertation directed to “Sub-pixel Registration in Computational Imaging and Applications to Enhancement of Maxillofacial CT Data,” which “focused on registration and alignment of 2D images and 3D digitized data obtained by dental CT scans and dental imprints of a patient.” Id. ¶¶ 8, 9.

Further, Patent Owner does not dispute Petitioner’s interpretation of limitations 1(1) and 1(2), or Petitioner’s identification of the corresponding function and structure in limitation 1(3).

In other words, the same updated image makes it possible not only to see the aligner outline 28 but also to see the dentition outline 16, through the aligner (FIG. 3). This single image therefore makes it possible to compare aligner 20 and dentition outlines. Advantageously, readjustment step 2), described later, is not needed. Ex. 1001, 6:15–20 (emphasis added).

Resp. 1. According to Patent Owner “[t]his discrepancy undermines the presumption of validity afforded to issued patents and makes it easier to invalidate a patent in an administrative forum than in a judicial proceeding.” Patent Owner cites no authority or evidence to support this argument. Moreover, the Supreme Court has held that the decision to grant a patent “is a matter involving public rights—specifically, the grant of a public franchise. Inter partes review is simply a reconsideration of that grant, and Congress has permissibly reserved the [U.S. Patent and Trademark Office’s (“USPTO’s” or “PTO’s”)] authority to conduct that reconsideration.” Oil States Energy Servs., LLC v.

  RulingsFinal written decision

  • BurdenNot shown unpatentable

    “A petition must identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3) Here, Petitioner merely provides general assertions about multiple references, without clearly identifying how, or why a POSITA would have been motivated, to modify the processes disclosed in those references to arrive at the claimed invention. Thus, the Petition does not state with particularity that Saxler’s particular technique for etching is to be used instead of Beach’s etching step when substituting Beach’s self-aligned process for Saxler’s two mask process. Nor does the Petitioner provide a sufficient reason, absent hindsight, why a POSITA would have been motivated to combine the references to result in a process that forms Saxler’s Modified Figure 1A. Thus, for these additional reasons, Petitioner has not shown by a preponderance of the evidence that claim 1 would have been obvious over Saxler, Beach, and Shenoy.” slip op. at 34

During the hearing, Petitioner admitted that Dr. Shealy’s “statement to modify the reference depending on what you're trying to accomplish” means that “a POSITA may modify with reason to do so.

    “remove the recess in Saxler Figure 1A to arrive at the allegedly enhancement mode transistor of Modified Figure 1A. Contrary to Petitioner’s assertions in its Reply and at the hearing, the Petition makes no argument that a POSITA would have removed the recess from Saxler Figure 1A to realize the benefits of an enhancement mode transistor. See Reply 4–5; Pet. 24–68. Rather, the Petition merely asserts that a POSITA would have understood that the gate recess of Figure 1A is optional without providing any persuasive reason why a POSITA would have removed the gate recess but retained the sloped sidewalls of Figure 1A. Pet. 25, 40, 45. For example, Petitioner asserts that Saxler’s gate contact may be “recessed or non-recessed” and that when the gate recess shown in Figure 1A is not utilized, Saxler would have the structure of Saxler Modified Figure 1A. Pet. 25 (citing Ex. 1003 ¶ 81; Ex. 1007 ¶ 52, 66); see also Pet. 40, 45 (citing Ex. 1007 ¶ 52). Neither of these paragraphs provide sufficient motivation to a POSITA to remove the gate recess from Saxler Figure 1A. Saxler paragraph 52 states: Exemplary devices according to some embodiments of the present invention are schematically illustrated in FIGS. 1A through 6. Thus, while embodiments of the present invention are described herein with reference to a recessed gate structure or a non-recessed gate structure, other embodiments of the present invention may include or not include a gate recess. Accordingly, embodiments of the present invention should not be construed as limited to the particular exemplary embodiments described herein but may include any suitable structure having a cap layer and/or passivation layer as described herein. Ex. 1007 ¶ 52. Petitioner’s expert, Dr. Shealy states that he understands paragraph 52 to mean that it is “fair game to pull the recess out of any of those figures [Figures 1A through 6].” Ex. 2004, 39:12–21.

    “In the Institution Decision, we declined to adopt Petitioner’s proposed construction of the “side surfaces” limitation and determined that it was not necessary to further construe this term because “[t]he parties do not dispute that the language ‘side surfaces extending horizontally’ encompasses a gate material with sloped side surfaces as depicted in Figure 5 of the ’335 patent.” Inst. Dec. 11–16 (citing Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017); Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

We invited the parties to address this limitation further during the course of this trial, but neither party provided additional evidence or argument regarding the “side surfaces” limitation. Inst.

    “This evidence, particularly the language in the ’335 patent itself, undermines Patent Owner’s argument that “[t]he process for forming gate ledges using separate masks instead of the self-aligned process disclosed in the ’335 patent cannot produce ledges that are ‘substantially symmetric.’” PO Resp. 39 (emphasis added); see also PO Resp. 42–43 (arguing that a gate structure with ledges having substantially equal widths is “not achievable” without using a single photo-mask process). We have considered the evidence presented by Patent Owner and Dr. Schubert in support of Patent Owner’s arguments. PO Resp. 38–43; Ex. 2005 ¶¶ 49–51. We, however, are unable to discern sufficient evidence supporting a conclusion that using separate masks cannot produce ledges that are substantially symmetric, particularly when the ’335 patent suggests otherwise. See Ex. 1001, 4:60– 63 (referring only to the “possibility of misalignment”).
