    “We agree with Patent Owner that Petitioner’s contentions in this ground do not cure the issues for limitations 1D and 1E. Petitioner’s contentions in this ground involve combining Khan and Ali’s teachings of identifying a horizon line and lane lines with Choe. For example, Petitioner argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have combined known elements according to known methods to yield predictable results” and that “[i]mplementing these known mathematical models in Choe’s calibration system, according to their known functions, would have yielded predictable results.” Pet. 39. Petitioner further argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have used a known technique (predictive models) to improve similar devices in the same way” and that “[u]sing predictive models for Choe’s lane and horizon prediction would have also applied a known technique (predictive models) to a known device (a manual annotator device) ready for improvement.” Pet. 40. Petitioner’s proposed combination, therefore, still relies on Choe’s teachings of transmitting an overlaid image to an annotator device. We note that Petitioner asserts that, “[o]nce Khan in view of Ali identifies the horizon and lane lines, it overlays the horizon line and/or lane lines on the video, as shown in the screenshots below.” Pet. 41–42. Although Petitioner mentions Khan and Ali’s teachings with respect to video here, Petitioner does not adequately explain how the teaching of an overlaid video would be combined with Choe’s single image annotator teachings. As discussed above, Choe discloses transmitting a single overlaid image to the annotator” slip op. at 23

    “Thus, Petitioner has not provided sufficient evidence and argument to explain how the additional teachings of Khan and Ali teach limitations 1D and 1E in combination with Choe. Petitioner, therefore, has not demonstrated unpatentability of claims 1–5 by a preponderance of the evidence. F. Obviousness over Choe and Workman (Claims 1–4) Petitioner asserts that claims 1–4 would have been obvious over the combined teachings of Choe and Workman. Pet. 47–52; Pet. Reply 26–30. Petitioner asserts that, “if [Patent Owner] alleges that Choe does not explicitly disclose which predictive models it uses or whether it uses predictive models to identify the horizon line, a [person of ordinary skill in the art] would have searched for references that use predictive models and how such models were used,” which “would have led to Workman, which discloses predictive models to identify the horizon line.” Pet. 47. According to Petitioner, “[u]sing Workman’s predictive model to identify the horizon line would also have merely been combining known elements ([convolutional neural networks (CNNs)] and annotation for camera calibration) according to known methods to yield predictable results and used known techniques (CNNs) to improve similar devices in the same way.” Pet. 48–49. Thus, Petitioner relies on Workman to teach a predictive model to identify a horizon line. See Pet. 47–49. Choe with respect to limitations 1D and 1E. Indeed, Workman involves horizon line estimation in single images. See Ex. 1011, 10 (§ 5) (“We introduced Horizon Lines in the Wild (HLW), a new dataset for single image horizon line estimation, to address the limitations of existing horizon line detection datasets.”).

    “in these respects. The preambles of claims 17 and 59 recite the “audio device wearable by a user for storing locally generated audio.” There is neither mention of “multi-track” audio in the claim, nor is the audio device limited to capturing a single source of sound, such as a single performer. Accordingly, we are not persuaded that the ’443 and ’207 patent claims support the limited scope that Patent Owner urges for the term “locally generated audio.” None of Patent Owner’s citations to the specification define or require that the “locally generated audio” correspond to audio generated only by a single performer. See, e.g., 230 IPR, Ex. 1001, 8:59−62 (stating that the local audio input device “may be worn by the performer and connects to local audio device 102 at local audio input device port 314”). Patent Owner’s argument that the specification “teaches a single creator/performer per local audio device” is well-taken, but the teachings do not indicate the intent to exclude other sounds from being captured at the local audio device (or indicate how the device would prevent the capture of other sounds, such that the audio would be “isolated” as Patent Owner contends). See 230 Sur-Reply 10 (citing 230 IPR, Ex. 1001, 4:28−32, 10:29−34, and Insituform Techs., Inc. v. Cat Contr., Inc., 99 F.3d 1098, 1105 (Fed. Cir. 1996) (“[C]laim 1 refers to ‘a cup’ and ‘the cup’ repeatedly, suggesting that only one cup is involved . . . . [N]either the specification nor the drawings disclose the use of more than one cup.”)). For instance, the specification describes that the “independent track of audio is received from one of the performer’s local audio device 102.” 230 IPR, Ex. 1001, 10:33−34. Thus, in this description the audio track corresponds to the audio captured by a particular audio device—which was worn by the performer— but does not limit that captured audio to only sounds made by the performer. As to the “local audio data” term, Patent Owner argues that “audio data” means “mono or stereo audio files created from independent, isolated locally generated audio files, such files suitable for creation of a multi-track audio file.” 230 PO Resp. 9−10 (citing Ex. 2140 ¶¶ 131, 134). This argument is unsupported by the claim language or specification. The claim does not require the creation of audio files, much less a “multi-track audio file.” The specification describes storing audio files in memory without the specificity that Patent Owner urges we adopt. See 230 IPR, Ex. 1001, 13:1−14. Accordingly, we are not persuaded by Patent Owner’s proposed construction of “local audio data.” Rather, we understand “audio data” to have a plain and ordinary meaning, such as the one given to the term by the District Court in the underlying litigation. 230 IPR, Ex. 1037, 10. We adopt the District Court’s construction of “audio data” to mean “data comprising audio signals in digital form.” Id. This finds support in the specification as the audio is described as being converted into digital audio and stored in a file. See 230 IPR, Ex. 1001, 13:1−14.

  • Expert testimonySkill level petitioner adoptedOther

    “E. Level of Ordinary Skill in the Art Based on the argument and evidence presented in the Petition and Patent Owner’s preliminary response, we determined, as stated in our Decision on Institution, that “a person of ordinary skill in the art would have had a Bachelor’s degree in electrical engineering and two or more years of experience working with audio and wireless communications systems.” 230 Dec. on Inst. 16; 232 Dec. on Inst. 22−23. Patent Owner reiterates its position that a person of ordinary skill the art would have had “a bachelor’s degree in electrical engineering or a related subject and two to five years’ experience working with multi-track audio and wireless communications systems in the professional performance industry.” 230 IPR, PO Resp. 6−7 (emphasis added) (identical passage in 232 PO Resp. 8). Thus, the dispute centers on whether the level or ordinary skill includes specific work experience with multi-track audio in the professional performance industry. We do not agree that this specific work experience is necessary to the level of ordinary skill in the instant proceedings. In determining whether an invention would have been obvious at the time it was made, we consider the level of ordinary skill in the pertinent art at the time of the invention. Graham v. John Deere, 383 U.S. 1, 17−18 (1966). “The importance of resolving the level of ordinary skill in the art lies in the necessity of maintaining objectivity in the obviousness inquiry.” Ryko Mfg. Co. v. Nu‑Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991). The “person of ordinary skill in the art” is a hypothetical construct, from whose vantage point obviousness is assessed. In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). In determining the level or ordinary skill, we may consider various factors including “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, 57 F.3d 1573, 1579, (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986)). Patent Owner’s proposed specificity of work with multi-track audio in a professional performance industry is not supported by the record. First, Patent Owner submits conclusory declaration testimony of James DeFilippis—repeating verbatim, and without any supported reasoning, Patent Owner’s proposed level of ordinary skill.

An indication that a new issue is improperly raised in a reply is where a petitioner submits “new evidence necessary to make out a prima facie case” of unpatentability, such as a “newly raised rationale to combine the prior art references that was not expressed in the petition.” Id. That is the case here. Petitioner’s rationale in the Petition for why a person of ordinary skill in the art would have been motivated to lower Bowen’s 0.9 eV barrier height to 0.33 eV based on Soukup was that such an artisan would have expected lowering the barrier height to increase TMR. See Pet. 34–36. Faced with Dr. Bokor’s testimony on cross-examination, Petitioner presents a new theory in its Reply that a person of ordinary skill in the art would not have known what impact lowering the barrier height would have (increase TMR, decrease it, or have no impact at all), but would have expected it to change in some “uncertain” way, which is a “legally sufficient motivation” in Petitioner’s view. See Reply 6–10, 13–16, 23–25. In other words, “[r]ather than explaining how its original” position that lowering barrier height would increase TMR “was correct,” Petitioner articulated “an entirely new theory . . . absent from the [P]etition” after Patent Owner cross-examined Dr. Bokor and “pointed out the flaws of [Petitioner’s] position” in its Response. See Wasica Finance GmbH v. Continental Auto. Sys., Inc., 853 F.3d 1272, 1286 (Fed.

    “Ultimately, the cross-examination testimony above is inconsistent with Dr. Bokor’s opinions in his declaration that, for example, “[i]t was understood to one of skill that lowering the barrier height to increase tunneling would have increased the TMR,” and “[o]ne of skill would have been motivated to adjust oxygen vacancy defects to improve TMR by lowering the barrier height.” See Ex. 1024 ¶¶ 176, 277 (emphasis added); see also id. ¶ 172 (“[O]ne of skill in the art would have been motivated to use [Soukup’s 0.33 eV] or similar height in an MgO MTJ to improve tunneling and hence TMR in Bowen.”). Accordingly, we do not find Dr. Bokor’s declaration testimony regarding a motivation to lower Bowen’s barrier height credible. It is Petitioner’s burden to provide a reasoned, evidence-supported explanation for why a person of ordinary skill in the art would have been motivated to lower Bowen’s 0.9 eV barrier height to 0.33 eV as disclosed in Soukup. See NuVasive, 842 F.3d at 1383; Magnum Oil, 829 F.3d at 1380; TriVascular, 812 F.3d at 1066.

As discussed above in Section II.C.2, we interpret “other connections” to mean “existing connections in the network that already have bandwidth allocated to them.” Because the information shared in Dziong and Sathyanath, described below, relates to reserved protection paths, rather than existing connections that have bandwidth that can currently transmit network traffic, the references do not teach or suggest the “other connections” part of the sharing definition in limitations 1.2 and 1.3. Dziong describes advertising, across the network, the amount of bandwidth reserved for recovery on each link that would be activated when a protected link fails. See, e.g., Ex. 1005 ¶ 60; Pet. 36. Once activated, network traffic from a “primary path” failure is rerouted to these recovery paths. See Ex. 1005 ¶¶ 7–9, 70, 83.

However, since the advertised information only contains information about the recovery paths “that would be activated” upon a primary path failure, such paths are not existing connections that already have bandwidth allocated to them, and therefore do not teach the claimed “other connections” that are part of the sharing definition.

    “said integrity is compromised, then also providing an indication of said compromised integrity.” Ex. 1001, 20:65–21:2. Although Petitioner points out that the limitation does not expressly recite “‘specifically’ monitoring the tight coupling” (Pet. Reply 8), the structure of the clause suggests that the tight coupling is specifically monitored. At a high level, the limitation is straightforward in its recitation that the integrity being monitored is “of the tight coupling” (Ex. 1001, 20:65–66 (emphasis added)), plainly suggesting that the tight coupling is specifically monitored. More granularly, breaking the relevant clause down to its grammatical parts, the clause recites a gerund (“monitoring”) acting on a direct object (“the integrity”) which is modified by a prepositional phrase (“of the tight coupling”). Notably, the object of the preposition (“of”) is “the tight coupling.” Altogether, this reads that the integrity being monitored is specifically of the tight coupling. Also, the claim recites that “if said integrity is compromised, then also providing an indication of said compromised integrity.” Therefore, from the claim language we know that the “integrity” of the tight coupling is something that may be “compromised,” which is consistent with Patent Owner’s proposed construction of determining whether the physical coupling has been “accessed or disturbed.” Petitioner’s interpretation effectively inserts additional language into the limitation such that the limitation includes monitoring the integrity of a device containing or surrounding the tight coupling, such as a camera (or camera housing), e.g., “monitoring the integrity of a camera that includes the tight coupling.” But, because the plain reading and the structure of the limitation reads that it is specifically the tight coupling’s integrity—not another physical structure, like a camera—which is being monitored, a monitored is not consistent with the language of the claim. See PO Resp. 9 (arguing that “Petitioner’s construction is improper because the claim language explicitly requires monitoring the physical coupling between the memory and the sensor as opposed to some third structure” (emphasis omitted)).” slip op. at 17

    “We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012).

We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

    “Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

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.

See Reply 4–5; Pet. 24–68.

Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs).
