      “skill in the art, because Petitioner’s position is more consistent with the ’624 patent Specification and the prior art. Our ultimate determination, however, would be the same under either party’s proposal. The two levels of skill in the art put forth by Petitioner and Patent Owner are not substantially different and, in fact, overlap significantly. Neither party has persuasively explained how, if at all, the proposals of their respective experts regarding the level of ordinary skill change the analysis in this case. The Board, sitting as a non-jury tribunal with administrative expertise, is well-positioned to determine and assign appropriate weight to evidence presented by each declarant in this case. Gnosis S.P.A. v. S. Ala. Med. Sci. Found., IPR2013- 00118, Paper 64 at 43 (PTAB June 20, 2014). Accordingly, we evaluate each declarant’s testimony along with the remainder of the evidence before us to reach our conclusions. Moreover, an express definition of the level of ordinary skill is not required in all situations, as the level of ordinary skill in the art usually is evidenced by the references themselves. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that “specific findings on the level of skill in the art . . . [are not required] ‘where the prior art itself reflects an appropriate level and a need for testimony is not shown’” (quoting Litton Indus. Prods., Inc. v. Solid State Sys.

      “further corroborating evidence. Dr. Herb’s contentions from the prosecution of Application No. 16/516,792 not only concern another patent application altogether, but are merely a portion of the evidence we have before us concerning the tie layer arguments and the interpretation of that term. Other evidence suffices to corroborate Petitioner’s contentions, and the Herb Declaration is ineffective, in view of the totality of the evidence, to refute Petitioner’s positions. Even if the disputed evidence is considered, we have accorded it its proper weight and we are nevertheless unpersuaded that Patent Owner has prevailed in its arguments.

      “Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Optional or preferred embodiments of particular configurations disclosed in Riis do not rise to the level of teaching away. Additionally, our reviewing court has explained that a reference must be “considered for all it taught, disclosures that diverged and taught away from the invention at hand as well as disclosures that pointed towards and taught the invention at hand.” Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 296 (Fed. Circ. 1985). Riis’s teaching of using LDPE, an acknowledged adhesive layer and a “workhorse” among layers, points towards and teaches the invention at hand. We already addressed, above, the interpretation of “tie layer” and the function of Riis’s LDPE layer as a tie layer, and for similar reasons, disagree that Riis’s disclosure of an LDPE layer constitutes a “teaching away” as argued by Patent Owner. Finally, Patent Owner’s “peelable” arguments are insufficiently explained, as noted by Petitioner, to persuasively support Patent Owner’s teaching away arguments. Reply 16. Accordingly, we do not find any teaching away in Riis of using LDPE as a tie layer.” slip op. at 43

    • Skill levelSkill level patent owner adoptedDecided for patent owner

      “Based on the record as a whole with emphasis on the technical level the ’345 patent’s disclosure and asserted prior art, we agree with Patent Owner that a degree in physics and/or optics rather than engineering could be sufficient. We disagree, however, that “at least two years work experience” is unclear. “At least two years work experience” refers to two or more years of experience working in the field of design, operation, and functioning of imaging systems. We, thus, determine that that a person of ordinary skill in the art as of the date of the invention would have had at least a bachelor’s degree in engineering, physics, or optics with relevant coursework, and the equivalent of at least two years of work experience in the design, operation, and functioning of imaging systems, amounting to familiarity with concepts related to illumination and detection schemes for optical imaging systems. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “The matter now before us is distinguishable from Xerox. As we explain below, Petitioner establishes unpatentability of the amended claims by extensively citing evidence including the prior art at issue. Petitioner and Dr. Georgakoudi properly map the Patent Owner’s amended claims to the explicit teachings of the asserted art. Sur-Reply 1–2. Thus, the position of Petitioner and Dr. Georgakoudi is not unduly conclusory. Rather, Dr. Georgakoudi’s testimony is generally credible because it is consistent with and tied closely to the teachings of the cited art. Thus, when choosing whether or not to cite Dr. Georgakoudi’s testimony and consider whether or not it is credible with respect to any given issue, we do so while considering the record as a whole.” slip op. at 12

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “5. Reason to Combine We first address the combination of Petit and Fawzy . Petitioner argues that it would have been obvious to a person having ordinary skill in the art to combine Petit’s long pass filter with Fawzy’s imaging apparatus. Opp. 8. Petitioner’s argument is supported by a preponderance of the evidence. Both Fawzy and Petit teach devices for capturing and analyzing images of dermatological conditions based on light wavelengths reflecting off a patient’s skin. Id. (citing Ex. 1008 ¶¶ 89, 92; Ex. 1020 ¶ 88). The preponderance of evidence supports that a person of ordinary skill in the art would have understood that emission filters, such as those taught by Petit, are a well-known mechanism to predictably filter out wavelengths of light that are not relevant to the imaging at hand. Id. (citing Ex. 1020 ¶ 87). A person of ordinary would have understood that filtering out undesired wavelengths could avoid undesired interference. Id. at 8–9 (citing Ex. 1008 ¶¶ 44,80). Petit teaches a long-pass filter having a cut-on wavelength of 450±25 nm. Ex. 1020 ¶ 98. Such a filter would be helpful in accomplishing Fawzy’s goal of “control[ling] optical coupling of the digital camera to capture only reflected light originating from the interaction of light from the spectral light source with an object being imaged.” Ex. 1008 ¶ 107. The combination would also be helpful for determining effective treatment as Petit teaches. Ex. 1020 ¶ 87. As such, we determine that a person having ordinary skill in the art would have had reason to combine Petit’s long pass filter with Fawzy’s imaging apparatus and would have had a reasonable expectation of success in making the combination.” slip op. at 18

      “B. Patent Owner’s Objections to Petitioner’s Demonstrative Slides Patent Owner objects to a number of Petitioner’s demonstratives for oral argument because, for example, the demonstratives constitute evidence that Petitioner did not reference or discuss in a prior paper. See, e.g., Paper 29 passim. We have considered the objections. Demonstratives for oral argument, however, are not evidence. Paper 24, 2 (Order Setting Oral Argument); see also Consolidated Trial Practice Guide 84, available at https://www.uspto.gov/TrialPracticeGuideConsolidated (“Demonstrative exhibits used at the final hearing are aids to oral argument and not evidence.”). We do not rely on demonstratives as evidence in our decision making; instead, we rely solely on the arguments properly presented in the parties’ briefs and the evidence of record.

The specification of the ’304 patent describes its technical field as relating to a smart card that may comprise an RFID (radio frequency identification) chip with antenna components for operating in contactless modes. Ex. 1001, 1:37–54. The specification discusses both inductive and capacitive coupling. See, e.g., id. at 3:14–39.

      “Ex. 1020, 11:46–57. We agree with Petitioner and find that the combination of Plassmann, Treuillet, and Staller teaches this limitation. First, we agree with Petitioner and find that Plassmann teaches a positioning system that uses a pair of light beamers to signal when a target subject is reaching a predefined distance position to the camera. See Ex. 1007, Fig. 1A (light beamers 6a, 6b); Pet. 33. Plassmann teaches that light beams converge at a predefined distance “corresponding to the distance in which the camera lens is focussed.” Ex. 1007, 12:7–13. More specifically, Plassmann states the following: The apparatus is also provided with two low-powered light emitting diodes (LEDs) 6a, 6b, each provided with a focussing lens to produce a beam of light and being arranged so that the beams converge and meet at a point a fixed and desired distance from the apparatus, this distance corresponding to the distance at which the camera lens is focussed. Id.; Pet. 34. Accordingly, we find that Plassmann teaches the limitation, save for having a second predefined distance position—if there are two different distance positions, one necessarily is closer to the camera body and the other one farther. Ex. 1007, 12:7–13, Fig. 1A. Second, we agree with Petitioner and find that Staller teaches a positioning system having more than one predefined imaging distance position. Pet. 38. More specifically, we find that Staller teaches a strobe diffuser attachment for a camera, which includes a “distance measurement device [that] may be adapted to selectively produce one of a plurality of pairs of light beams which intersect at different repeatable distances from the diffuser body.” Ex. 1006, code (57), 2:29–32, 5:13–15; see also id. at 5:56– 6:2 (“[T]wo pairs of light beam emitters . . . may be used to provide three or four separate pairs of intersecting bea[m]s and three or four corresponding repeatable distances for diffuser 10.”); Pet. 38. In other words, Staller teaches having at least two distinct predefined distance positions for the camera. Ex. 1006, code (57), 2:29–32, 5:13–15, 5:56–6:2. We also agree with Petitioner and find that Staller teaches that its “distance indicator improves the usefulness of close range photography by providing a repeatable scale to photographs[, which] . . . improves the usefulness of close ranges photographs for medical and other organic growth measurement applications.” Ex. 1006, 6:10–15; Pet. 38. In addition, we agree with Petitioner and find that Plassmann teaches that “[s]tereoscopic imaging has been known for many years,” and “ha[s] been used to measure the shape of wounds and the like which are otherwise difficult to measure by conventional techniques.” Ex. 1007, 1:6–15; Pet. 35. We also agree with Petitioner and find that it was known in the art before the ’253 patent to use a camera having multiple predefined distances for imaging a subject in connection with wound or lesion treatment.

Pet. 36; Ex. 1003 ¶ 113; Ex. 1016, 755. A person of skill in the art would have understood that acceptable medical wound photographs would have to be adequately focused and that Treuillet, therefore, suggests a depth of field from 65 centimeters to 95 centimeters for the Plassmann device.

Staller teaches plurality of pairs of light beams that “intersect at a different repeatable distance from the diffuser body.” Pet. 23; Ex. 1006, code (57), 2:29–32, 5:13–15; see also id. at 5:56– 6:2 (“[T]wo pairs of light beam emitters . . . may be used to provide three or four separate pairs of intersecting bea[m]s and three or four corresponding repeatable distances for diffuser 10.”).

      “Petitioner’s proposal is too broad. PO Resp. 8. For example, a person who merely installs solar panels for three years (satisfying “professional experience in solar energy”) while having some familiarity with module manufacturing would not be of ordinary skill in the design aspects of the ’060 patent as, for example, reflected by the claims at issue and the ’060 patent’s text and figures. See, e.g., Ex. 1001, Figs. 2a, 2b, 3a, 3b, 4a, 4b, 3:22–7:44. On the other hand, we also determine that Patent Owner’s proposal is too narrow. A person could, for example, have ordinary skill in the art of the ’060 patent by virtue of non-professional experience (for example, academic experience). When assessing relevant experience, research work done for a university (beyond mere classroom study) would have been just as valuable as research work done for a corporation. Also, ordinary skill in the art could be demonstrated by work that requires understanding of the ’060 patent’s field even if not “designing, developing, and/or researching” in the field itself. We, thus, determine that a person of ordinary skill in the art of the ’060 patent would have been someone with a bachelor’s degree in electrical engineering, applied physics, or the like, and at least two years of (a) experience designing, developing, and/or researching in the field or (b) experience in solar energy that required an understanding of the ’060 patent’s field.

In other words, Dr. Leburton’s analysis treated the preambles as limiting; however, that does not compel a conclusion that the preambles are limiting. Dr. Leburton also testified that the preamble provides context for the remainder of the claim. Id. at 125:8–15 (agreeing that “the phrase, for example, a method of forming a gate of a transistor is providing a context of what needs to be performed in order to practice this claim”). But providing context for the limitations in the claim body is tantamount to reciting “a purpose or intended use for the invention,” which typically does not limit the claims. TomTom, Inc. v.

Patent Owner argues that Petitioner’s additional citations and evidence are too late, and should have been raised in the Petition. PO Sur-Reply 15. We do not agree. Petitioner reasonably responds to an issue discussed in the Institution Decision and Patent Owner Response. See Inst. 8; PO Resp. 30–31. Dr. Leburton’s testimony cited in the Petition sufficiently established Petitioner’s contention to permit elaboration during the trial, and the full record supports that annealing Yoon’s silicon substrate as taught by Chern would have reduced interface roughness and therefore the resistivity between the polysilicon and additional layers. That benefit would have sufficiently motivated skilled artisans to make the asserted combination. Even if we were to discount that aspect of Petitioner’s proffered motivation, however, we determine that reduced susceptibility to peeling also would have motivated skilled artisans to anneal Yoon’s substrate. Petitioner relies on Chern’s statement that “[p]erforming the polysilicon annealing step prior to forming a diffusion barrier layer has been experimentally proven to reduce the subsequently formed diffusion barrier layer’s susceptibility to peeling.” Ex. 1006, 3:31–38; Pet. 14–15. Patent Owner argues that Chern’s disclosure of reduced peeling susceptibility relates only to depositing a barrier layer on the annealed polysilicon. PO Resp. 33–34.

Id. at 34 (citing Ex. 2005, 67:23–68:6). While Patent Owner focuses on the tungsten nitride layer, we agree with Petitioner that the record supports reduced peeling for whatever material contacts the annealed substrate. Dr. Leburton testified that annealing a polysilicon substrate makes that material more “coherent and consistent” and improves its “contact with other materials.” Ex. 2005, 134:24–135:25. We agree with Petitioner that reducing peeling from the polysilicon substrate is a benefit to all upper layers, as they depend on the bottom layer remaining attached. See Pet. Reply 14–15. Thus, we conclude that skilled artisans had reason to anneal Yoon’s polysilicon substrate both to reduce additional layers’ susceptibility to peeling, and also to reduce interface roughness and resistivity.” slip op. at 13
