    “First, we find that Hackborn clearly discloses an embodiment in which swiping the finger, not just mere contact without motion (i.e., a tap), moves the blades of grass in the background wallpaper. Hackborn explicitly states: “In the example shown in FIG. 1, a user is swiping her finger across a touch-sensitive display screen of the computing device. In response, the blades of grass 105 displayed in the area of the screen swiped by the user are caused to bend or sway as if contacted by the user’s finger during the swipe.” Ex. 1004 ¶ 28. Because this description expressly refers to “swiping” or moving the finger “across” the display screen, it does not encompass a mere tap, or contact by the user that does not move on the display screen. If a single-tap-contact embodiment for moving the blades of grass in the background wallpaper is disclosed, it would be in an embodiment different from the swiping embodiment. Here, Petitioner is relying only on the swiping embodiment for moving the blades of grass in the background wallpaper. Thus, we disagree with Patent Owner that Hackborn discloses no need to distinguish a tap from a swipe. We find that in the swipe embodiment, it is important to distinguish a tap from a swipe, and thus there is reason, as Petitioner contends, for one of ordinary skill in the art to look to Westerman for implementation details on how to make such a distinction. Specifically, for recognizing a swipe from a tap, Westerman describes determining whether the finger path displacement exceeds a predetermined threshold (Ex. 1005 ¶¶ 19, 61), and examining the initial velocity of the contact at contact’s touchdown (Ex. 1005 ¶¶ 19, 62). As for Patent Owner’s noting that in several instances Hackborn generally refers to a user’s finger contacting items on the wallpaper, that does not undermine Petitioner’s positions, because in the “swipe” embodiment, the referenced contact would be a swipe, and not a single tap without any motion of the finger.” slip op. at 17

According to independent claims 1 and 23, however, the displaying in sequence of the at least some of the plurality of images must be based in part on the magnitude of the first contact.

When I weigh the evidence, I find it to be one-sided, with all of the expert testimony weighing against Petitioner or avoiding the issue altogether. Thus, I would not find that Petitioner has met its burden to prove, by a preponderance of the evidence, that Zhao teaches claim limitation 1e. Moreover, even if the Majority is correct about how Zhao’s RCR algorithm works, all that shows is that the detection of object presence in a previous image can be used to disambiguate segments (e.g., limbs) of an already detected object (e.g., a person), not that it can be used to detect the object in the image in the first place, as required by the claim language.

    “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

Further, the benefits of Mozer identified by Petitioner are benefits that both Mozer and Smyth already have, without fabricating the calculating apparatus and the acoustic model memory on the same integrated circuit. Also, even if Petitioner had shown there was a reason to combine Smyth and Mozer, Petitioner does not persuasively show that the combination teaches “the calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” as recited in claim 1.

(emphasis added)); “it would have been obvious to modify Smyth to form the classifier processor and associated memory on a single IC” (Pet. 43 (emphasis added)); (“it was well known in the prior art to fabricate a single integrated circuit” (Pet. 43–44 (emphasis added)); “[t]hus, a POSITA would have been motivated . . . to fabricate [Smyth’s processor and state memory] on a single integrated circuit” (Pet. 44 (emphasis added)). integrated circuit to using integrated circuits that were already fabricated. Reply 22–25. According to Petitioner, “the Petition did not map a POSITA physically fabricating an IC, but rather mapped a POSITA modifying Smyth according to Mozer’s undisputed teachings of a single IC on which a calculating apparatus and acoustic model memory were already fabricated.” Id. at 23–24. However, as discussed in the previous paragraph, when discussing the combination of a processor and an acoustic model memory on an integrated circuit, the Petition used the verb “to fabricate” four times in the future tense and once in the present tense, as well as the verb “to form” once in the future tense. The Petition did not use the past tense phrase “were already fabricated” as alleged in the Reply. Moreover, the Petition did not map Smyth’s state memory (which the Petition contends teaches the claimed “acoustic model memory” (see Pet. 11)) to a memory already fabricated on an integrated circuit in the prior art. Rather, the Petition relied on Mozer to support its contention that a person of ordinary skill would have fabricated the calculating apparatus and acoustic model memory of Smyth on an integrated circuit. See Pet. 42, 44. The Petition cited Boike and Ozcelik in contending that fabricating an integrated circuit with processors and memories was well known, and cited Toyoda in contending that fabricating an integrated circuit with a calculating apparatus and an acoustic model memory was well known. Pet. 43–44 (citing Ex. 1006; Ex. 1029; Ex. 1034). However, the Petition did not explain how a memory located in one of the integrated circuits of Mozer, Boike, Ozcelik, or Toyoda would have been able to store Smyth’s state memory. Therefore, we disagree with Petitioner’s contention that “the Petition did not map a POSITA physically fabricating an IC, but rather mapped a single IC on which a calculating apparatus and acoustic model memory were already fabricated.” Reply 23–24. We find that this contention was untimely presented in the Reply. We do not permit Petitioner to propose a mapping of the prior art in the Petition and then completely change that mapping after Patent Owner argues the initial mapping was flawed.

    “Dr. Ducharme’s testimony that “the spacing of the chips in Zhang would not likely be so close as to create overheating issues” (Ex. 2002 ¶ 111) is unsupported by any disclosure of the actual spacing of Zhang’s chips. Consequently, his testimony that there would be no overheating concerns in Zhang due to the spacing of the chips is entitled to little, if any, weight. Dr. Ducharme further testifies that the components of Zhang’s driver “could easily increase the temperature of the LED 19 chips on the circuit board, which can cause LEDs to generate less illumination, burn out and otherwise adversely affect their performance.” Ex. 2002 ¶ 126. Dr. Ducharme further testifies that “[i]t is well-known that excessive operational temperatures can reduce the illumination provided by the LEDs, can decrease the operational lifetime of the LEDs, and if the temperature is sufficiently high, it can cause LED junction failure and a burnt-out LED.” Id. We agree with this testimony, which as discussed below, is consistent with Salam.

Dr. Ducharme testified that a person of ordinary skill in the art “would have an understanding of the generation of heat and using a heat sink to remove unwanted heat from electronics and LED lighting devices.” Ex. 1102, 23:18–24:3. Dr. Ducharme’s testimony is consistent with Petitioner’s contention that the combination of Zhang and Salam “would have been a straightforward combination of known components and technologies, according to known methods, to produce the predictable result of reducing/ mitigating heat effects in a circuit.” Pet. 17 (citing Ex. 1002 ¶ 106). Patent Owner next contends it would be extremely burdensome and costly to modify Zhang to add a heat sink layer because “each of the multiple chips mounted and epoxied to Zhang’s circuit board in the exit sign would have to be modified.” PO Resp. 30 (citing Ex. 2002 ¶ 112).

    “Overall, we find Dr. Holberg’s testimony particularly telling, and not very persuasive, with respect to combining Oliaei and Vittoz. Dr. Holberg makes clear that a person of ordinary skill in the art would have analyzed Oliaei’s circuit, and in particular any switches that were of concern, before implementing charge injection compensation circuitry. See, e.g., id. at 25:8– 26:22 (Dr. Holberg describing for a pacemaker amplifier circuit he designed “I definitely did a lot of analysis because I had to deal with the DC value, so I did a lot of analysis on the charge injection impact.”). Dr. Holberg did not, however, provide any technical analysis or circuit performance simulations in his original declaration showing that Oliaei would benefit from Vittoz’s charge injection compensation circuitry. See Ex. 1002 ¶¶ 200–218. Also, in his original Declaration, Dr. Holberg testified that “[a] POSITA could have combined the common-mode circuit and the common-mode feedback circuit of Oliaei with the impedance matching circuit of Vittoz using the known modeling methods disclosed by Vittoz.” Ex. 1002 ¶ 202 (citing Ex. 1012, 101–105, Fig. 7). The mere fact that the prior art reference could be modified does not satisfy the requirements for a finding of obviousness. Indeed, even if Vittoz’s charge injection circuit could be implemented in Oliaei’s CMFB circuit, and “a POSITA would recognize Vittoz’s balancing capacitors and dummy switches would operate in substantially the same way, whether in the system disclosed by Vittoz or the system disclosed by Oliaei,” as Dr. Holberg testifies, this does not explain persuasively why a person of ordinary skill in the art would have added Vittoz’s charge injection circuitry into Oliaei’s CMFB circuit.” slip op. at 44

    “Considering all the evidence of record, we agree with Patent Owner that Petitioner has not asserted sufficient rationale for the combination of Oliaei and Vittoz. See PO Resp. 51–77; Ex. 2002 ¶¶ 71–103. Petitioner alleges similarities between Oliaei and Vittoz and that the resulting combination, based on a desire to compensate for charge injection, would have predictably yielded the claimed system. Pet. 77–81. The arguments and evidence are deficient, however, for several reasons. First, as discussed above, we considered Petitioner’s assertion that a person of skill in the art would consider charge injection as a reason to look to Vittoz. Pet. 77. The evidence from both Dr. Holberg and Dr. Kinget is clear, however, that charge injection is not always necessary or compensated for in every switched capacitor circuit. See, e.g., Ex. 2003, 39:16–18 (Dr. Holberg stating that “I’m sure I’ve never put charge compensation circuitry on every switch. I’m sure of that.”). Second, Petitioner’s evidence including simulations of the combined Oliaei and Vittoz teachings, together with Patent Owner’s simulation evidence, illustrate that there are no clear-cut improvements in Oliaei’s circuit. The experts’ simulations, as a whole, show that by choosing particular parameters Oliaei’s circuit performance might be improved, and choosing other reasonable parameters would not improve circuit performance. With results of the simulations going both ways, the evidence is not persuasive that the combination would have yielded a predictable result. Third, the alleged rationale of adding charge injection compensation does not address sufficiently the reason a person of ordinary skill in the art would combine the relevant teachings of Oliaei and Vittoz. Oliaei expressly discloses that the inventors undertook “numerous” simulations to address issues of clock-feedthrough glitches, i.e., charge injection, and that the results showed no impact of charge injection on system performance. Ex. 1007 5:17–32. Without sufficient explanation, Petitioner and Dr. Holberg have failed to present a persuasive rationale for the alleged combination.” slip op. at 49

That undisputed fact, together with Petitioner’s other evidence, is sufficient to establish a motivation to combine.” slip op. at 42

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Level of Ordinary Skill in the Art For purposes of our Institution Decision, we accepted the definition of a person of ordinary skill in the art (“POSITA”) provided by Petitioner’s declarant, Dr. Vachon. Dec. 11 (citing Ex. 1006 ¶ 28). That definition is: a person having a bachelor’s degree or the equivalent training or experience in mechanical engineering, bioengineering, or related field and at least three years of experience relating to biosensor research and development, or a master’s degree or the equivalent training or experience in mechanical engineering, bioengineering, or related field, and at least one year of experience relating to biosensor research and development. Id. Patent (https://www.uspto.gov/sites/default/files/documents/guidance_on_motions_ to_amend_11_2017.pdf); Bosch Automotive Service Solutions, LLC v. Matal, 878 F.3d 1027 (Fed. Cir. 2017); Bosch Automotive Service Solutions, LLC v. Iancu, Order on Petition for Panel Rehearing, No. 2015-1928 (Fed. Cir. Mar. 15, 2018). Owner’s declarant accepts and applies this definition of a POSITA for purposes of his opinions. Ex. 2008 ¶ 30. Neither party’s declarant indicates that any proffered opinion would change depending on the level of ordinary skill in the art. Therefore, consistent with our Institution Decision, we adopt Dr. Vachon’s definition of a POSITA. Ex. 1006 ¶ 28. We also rely on the cited prior art references as reflecting the level of ordinary skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 20
