    “We agree with Petitioner that the term “3D slices” has no apparent connection to the phrase “direct volume rendering.” Patent Owner’s argument appears to be that DVR “requires an image of the entire anatomical volume that is neither feature-specific nor segmented, [which] would seemingly require that all inner layers be displayed.” Reply 4; see Sur-reply 6–10 (not disputing Petitioner’s characterization). But, as Petitioner notes, the specification directly undermines this by teaching “display [of] a slice of the 3D data instead of a volume of the 3D data.” See Reply 4 n.2 (quoting Ex. 1001, 5:34–35). In other words, to the extent DVR would depict an image of the entire anatomical volume, displaying 3D slices “instead of a volume of the 3D data” implies the opposite of DVR. Even if “3D slices” somehow implied DVR, Patent Owner’s position is still untenable. Claim 1 does not recite “3D slices.” Instead, claim 1 recites “3D data” and “inner layers.” Ex. 1001, 18:54–65. Patent Owner fails to clarify the relationship between “slices,” “3D data,” and “layers,” and its expert even admits that slices and layers are two different things. See PO Resp. 13; Ex. 1022, 32:7–16 (agreeing that the words “slice” and “layer” are not “synonyms”), cited in Reply 4. We also agree with Petitioner that dependent claim 3 distinguishes slices and layers by reciting “slices of the projected inner layer.” Reply 4 (quoting Ex. 1001, 19:3–10). Thus, even if 3D slices somehow implied DVR, the language of claim 1 does not support limiting the claim this way.” slip op. at 12

  • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

    “The determination of whether a document was publicly accessible “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to members of the public.” Medtronic, Inc. v. Barry, 891 F.3d 1368, 1380 (Fed. Cir. 2018). For instance, courts routinely rely on the Wayback Machine to determine when a reference was first made available to the public. Valve Corp. v. Ironburg Inventions Ltd., 8 F.4th 1364, 1374 (Fed. Cir. 2021) (“District courts have taken judicial notice of the contents of webpages available through the Wayback Machine ‘as facts that can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.’”). We disagree with Patent Owner’s argument that “Medivis cannot rely on additional prior art”—Exhibits 1023 and 1024—“that was submitted after its Petition to carry its burden without leave from the Board.” Sur-reply 4. As Patent Owner did not file a motion to exclude these exhibits, we decline Patent Owner’s invitation to disregard them. We also find Petitioner’s Reply argument proper because it directly responds to Patent Owner’s contention that Petitioner did not prove the public accessibility of Amira. See Chamberlain Grp., Inc. v. One World Techs., Inc., 944 F.3d, 919, 925 on issues previously raised.”). Petitioner’s Reply argument appropriately elaborates on the Petition’s contention that Amira was publicly accessible. Patent Owner also does not dispute the substance of Petitioner’s evidence. For example, Patent Owner does not address the substance of Mr. Frank-White’s declaration. We find that this evidence, including Mr. Frank- White’s declaration testimony, persuasively supports the public availability of Amira as of the date shown in the Wayback Machine URL.

Moreover, the cited extrinsic evidence––testimony by Patent Owner’s expert Dr. Lomp–– does not support Patent Owner’s proposed construction because it is internally inconsistent and also undermined by Dr. Lomp’s inconsistent deposition testimony. See Ex. 1036, 11:6–17, 12:9–12; Ex. 2010 ¶¶ 40, 48. Similarly, the extrinsic evidence cited by Petitioner (e.g., Exs. 1037, 1038, 2009) undermines Patent Owner’s position emphasizing the intended recipient devices of SIB1. In summary, we decline to adopt Patent Owner’s proposed claim construction because it is unsupported by the claim language, the ’670 Patent Specification, and the cited extrinsic evidence. with the ordinary and customary meaning which does not include limiting SIB1 to an ordinary legacy SIB and excluding MTC specific SIBs or SIBs intended for MTC devices.

As explained above, the burden of production shifted to Patent Owner to show that Wallen is not prior art because the ’670 Patent is entitled to the earlier January 20, 2012, filing date of foreign priority application GB1201000. See Dynamic Drinkware, 800 F.3d at 1379–1380. For a claim in a later-filed application to be entitled to the filing date of an earlier application, the earlier application must provide written description support for the claimed subject matter. Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v.

Petitioner implicitly acknowledges that Wallen does not expressly disclose a physical broadcast channel (PBCH), but relies on Berggren for confirming that the LTE standard specifies that a PBCH carries the MIB. See Pet. 42–43 (citing Ex. 1003 ¶ 74; Ex. 1007 ¶¶ 73–75). According to Petitioner, “a person of ordinary skill in the art would have been motivated to transmit Wallen’s MIB using a PBCH as taught by Berggren.” Pet. 43 (citing Pet. 33–38). In particular, Petitioner asserts that a person of ordinary skill in the art “would have been motivated for Wallen’s LTE system to utilize the LTE standard implementation details taught by Berggren,” and “it would have been predictable and beneficial for Wallen’s user equipment to receive the MIB in the [PBCH], as was standard in LTE.” Pet. 34 (citing Ex. 1003 ¶ 58), 37 (citing Ex. 1003 ¶ 63). According to Petitioner, “the combination is nothing more than ‘the predictable use of prior art elements according to their established functions.’” Pet. 38 (citing KSR, 550 U.S. at 417). Based on the entire record developed during trial, we are persuaded by a preponderance of the evidence that Petitioner provides sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify Wallen’s broadcast MIB with Berggren’s teachings of using a PBCH for transmitting broadcast MIBs.

    “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.

    “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.

Instead, we agree with Patent Owner that Suzuki’s irregular-surface smoothing describes covering defects, not suppressing the underlying cathode’s topography. PO Sur-reply 5. The smooth-surface passage that Petitioner highlights comes immediately after two sentences describing inevitable “defects,” “pinholes,” and “foreign matter” on the cathode surface and before a sentence describing “ensuring the formation of the layer 22, which is substantially defect-free.” Ex. 1012, 5:52–67.

  • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportDecided for petitioner

    “Patent Owner bears the burden of production to establish that its claimed invention is entitled to an earlier priority date for this fact-intensive issue. See In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1375–76 (Fed. Cir. 2016). We agree with Petitioner that the email chain does not support Patent Owner’s conception claim because it “does not discuss depositing a planarization layer, as required by both independent claims.” Pet. Reply 3. Patent Owner asserts that the inventor’s discussion of “PML” (polymer multi-layer) encapsulation in the email chain shows their conception of the claimed planarization layer because the ’389 patent describes that PMLs “‘[t]ypically’ include[e] ‘a planarization layer’ that ‘is provided to give a planar surface’ for deposition of an upper layer,” and “‘address ‘any point defects (i.e. pin holes)’ that might appear in the barrier layer’s surface.” PO Resp. 6 (quoting Ex. 1001, 1:31–37, 1:41–44, 1:56–62). We disagree with Patent Owner for two reasons. First, the challenged patent’s specification does not corroborate that the inventors conceived the claimed planarization before the challenged patent’s priority because it did not exist at the time of the email. Whether the inventors, at the time of filing, considered PMLs to typically include a planarization layer as of the claimed priority date does not support the allegation that they conceived of that same planarization layer more than a year earlier. Moreover, the ’389 patent’s teaching that “[t]ypically, for PML structures, a planarization layer 106 is formed” (Ex. 1001, 1:30–31) shows that the inventors recognized PML structures and planarization layers were distinct because only a subset of PML structures formed planarization layers, even if they do so typically. Thus, the inventor’s discussion of a PML layer in the email chain does not evidence their conception of the claimed planarization layer, as Patent Owner contends. Additionally, even if we were to understand the inventors’ mention of PML encapsulation in the emails, together with the discussion of patterning techniques for an organic layer, as discussing a planarization layer, such discussions are evidence of brainstorming ideas, rather than documenting the path taken with the claimed invention. For instance, the inventors use phrases like “don’t know if this will work,” “these are all just ‘undeveloped’ ideas,” and “looking forward to keep this discussion rolling.” Ex. 2006, 1; see also Ex. 1034, 59:22−59:18. As Petitioner argues, and we agree, these are more theoretical and future-development discussions than an exchange of a definite idea. Pet. Reply 2−3 (citing Hybritech Inc. v.

PO Resp. 17. According to Patent Owner, “[e]ven though the Federal Circuit has held that such references are ‘printed publications’ under 311(b), to preserve arguments on appeal, Patent Owner submits that such an interpretation is inconsistent with the plain statutory language, the precedent, and non-public accessibility of an unpublished patent application.” Id.

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

    “Yamazaki does not involve multiple devices on a substrate” and Ghosh teaches “non-selective deposition of at least the barrier layer.” PO Resp. 31. We disagree with this argument because it attacks Yamazaki and Ghosh individually, rather than the combination of Yamazaki’s selective deposition and Ghosh’s plurality of devices that Petitioner asserts. See In re Keller, 642 F.2d 413, 426 (CCPA 1981). We also disagree with Patent Owner’s criticism that Petitioner fails to explain why skilled artisans would have ignored Ghosh’s non-selective deposition method for barrier layers on multiple devices. PO Resp. 32. This argument attacks a straw man as Petitioner does not propose modifying Ghosh’s method with Yamazaki’s selective deposition. See Pet. 21–23. Rather, Petitioner proposes modifying Yamazaki’s selective deposition method by applying it to Ghosh’s teaching of encapsulating a plurality of OLED devices. Id. Next, Patent Owner asserts that skilled artisans would not have extended Yamazaki’s single-device fabrication/encapsulation method to a plurality of devices on a substrate because doing so would “multiply defects and errors, drop the yield exponentially, and increase the cost.” PO Resp. 34. Patent Owner asserts that precision/defect problems would be particularly acute when using Yamazaki’s inkjet method to print devices’ electro luminescence layers. Id. at 35–36. We disagree. Even if extending Yamazaki’s method to Ghosh’s multiple devices comes at a cost of potential defects, that tradeoff would not undermine Petitioner’s proffered combination given Petitioner’s articulated benefits outline above, including facilitating manufacturing display panels for OLEDs with improved throughput, improved productivity, and reduced manufacturing costs, as compared to fabricating/encapsulating just a single device. See Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000) (“The fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another.”). It also does not matter that “inkjet printing yielded devices of half the efficiency than spin coating,” as Patent Owner asserts (PO Resp. 35), because Petitioner does not need to show that Yamazaki’s inkjet printing would be the best option for batch fabrication/encapsulation, only that it would was a suitable one from which the prior art did not teach away. See Par Pharm., Inc. v. TWi Pharms., Inc., 773 F. 3d 1186, 1197–98 (Fed. Cir 2014). That is, Petitioner does not need to show that Yamazaki’s inkjet method was an improvement over other known fabrication/encapsulation methods, so long as it was a known fabrication/encapsulation method and skilled artisans would understand that implementing it for a plurality of devices had known advantages over fabricating/encapsulating a single device, which Petitioner identifies. See Pet. 22. We also agree with Dr. Subramanian that skilled artisans would have a reasonable expectation of success in making the proposed combination given similarities between the references (both are directed to encapsulation of an OLED display device with multiple thin-film layers and at least the first encapsulation is selectively deposited) and because “as the ’389 patent admits, in the prior art it was conventional to use batch fabrication to manufacture OLED display devices with thin-film encapsulation.” Ex. 1003 ¶ 86. As Dr. Subramanian explains, a particular advantage of inkjet printing is that it scales well to larger areas and it was known at the time of the ’389 patent that inkjet could be used to print multiple devices on a glass substrate. Ex. 1032 ¶¶ 2, 27–28. Patent Owner’s argument that “Yamazaki’s methods are far from ready for manufacturing” (PO Resp. 34) goes well beyond what is necessary to show that skilled artisans would have had a reasonable expectation of achieving what is claimed. See Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1367 (Fed. Cir. 2016). Given Petitioner’s analysis outlined above, we agree with Petitioner that it would have been obvious to skilled artisans to fabricate and encapsulate multiple OLED devices on a substrate using Yamazaki’s ink-jet methods. slip op. at 15
