“[W]ould have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or a related field, and 2–3 years of practical engineering experience relating to information security systems that employ cryptographic keys to encrypt/decrypt digital data. Additional education could substitute for professional experience, or significant experience in the field could substitute for formal education. Ex. 1003 ¶ 41. Patent Owner agrees with Petitioner’s expert regarding the level of ordinary skill in the art. RMTA 19. Patent Owner’s declarant, Dr. Villasenor, notes that “obviousness must be viewed from the perspective of one of ordinary skill in the field of information security using cryptographic keys for encryption and decryption of digital data, and my opinions are rendered on the basis of the definition of the ordinary artisan set forth in the Petition in view of that further clarification.” Ex. 2010 ¶ 19. Based on a review of the record, we adopt Petitioner’s proposed level of ordinary skill in the art because it is consistent with the evidence of record, including the asserted prior art and ’178 patent specification.

“Patent Owner argues that there was no motivation to combine Peterka with Suzuki because Petitioner has argued that “Peterka can already identify content keys by using the allegedly unique sequence numbers or time stamps assigned to each message carrying a single content key.” PO Resp. 41–42 (citing Pet. 25). Patent Owner also challenges motivation to combine Suzuki because it “is not directed to a pay-by-time, pay-per-view, or subscription distribution model, in which a content key grants access to content that different clients must individually decide to purchase in discrete units or increments.” Id. at 36–37. Petitioner responds that, because Peterka disclosed alternative embodiments that did not use sequence numbers or time stamps to identify EMM/ECM messages, one of ordinary skill would have been motivated specifically assign identifications to individual keys as taught in Suzuki. Reply 22 (citing Pet. 26). Petitioner also argues that whether Suzuki was directed to unpurchased content was irrelevant, because Suzuki is cited to show multiple key responses were conventional. Id. at 19–20. Patent Owner does not otherwise specifically address the issue of motivation to combine Peterka, Suzuki, and Bocharov. See generally PO Resp. Nonetheless the burden remains on Petitioner to demonstrate unpatentability. See Dynamic Drinkware, 800 F.3d at 1378. We find, based on the record, that Petitioner has proved by a preponderance of the evidence that a person of ordinary skill in the art would have had reason to combine the teachings of Peterka, Suzuki, and Bocharov as proffered by Petitioner with a reasonable expectation of success.” slip op. at 45
- ScopeMotion to amend, deniedDenied
“We agree with Petitioner that the substitute claims are broadening. Because the amended wording only requires the key request to be made “in response to detecting” the boundary, rather than “ahead of” the boundary, the request can occur before or after the boundary. This is not a fanciful or unlikely possibility — such delayed requests are specifically contemplated by the ’178 patent: [I]f the packager 104 is unable to obtain a new content encryption key from the WFM 102 prior to the expiration of the current content encryption key, the packager 104 will continue to use the current content encryption key until such time as it is able to obtain a new key from the WFM 102. Ex. 1001, 6:32–37. It should be noted that the fixed period duration for key rotation may be viewed as a "target" period, as the packager 104 may not expire a key on the exact boundary. Ex. 1001, 8:9–11. The key expiration time from the WFM 102 may be viewed as a "suggested" expiration time, as the packager 104 may not be able to expire the key at the exact specified time.” slip op. at 56

“In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve Dobashi’s RSm values. Dobashi teaches that because RSm “can be adopted as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66–3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66– 3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.

STANDARD OF REVIEW When rehearing a decision on institution, we do not review the merits of the decision de novo, but instead review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c).

“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[6] 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).” slip op. at 4

“Petitioner, however, does not adequately explain why a POSITA would have been motivated to modify Kim’s copper foil surface to have a Pc value of 19.2 as reported in Griesi. In particular, neither Petitioner nor Dr. Randall points us to, nor do we discern, any teaching in Griesi that a peak count of 19.2 provides any particular benefits or properties that would have lead a POSITA to modify Kim’s copper foil surface as Petitioner proposes. Instead, Petitioner’s arguments that a POSITA would have been motivated to modify Kim’s copper foil surface with Griesi’s peak count patent itself. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 421 (2007) (stating that the fact finder must be aware “of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning”).

“We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. 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). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

See, e.g., Ex. 1001, 5:20–21 (“The snapshot is parsed and analyzed by the security system 140 to detect vulnerabilities.”), 5:37–40 (“[T]he security system 140 may be configured to match the application files, either directly (using binary comparison) or by computing a cryptographic hash against [a] database of files in vulnerable applications.”). Because, as we explain below, Petitioner’s obviousness analysis is sufficient under this first approach, we take no position on Petitioner’s second alternative approach, which Patent Owner disputes. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co. Matal, 868 F.3d 1013, 1017 (Fed. Cir. 2017) (noting that “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). Pet. 8–10, we do not need to further construe the claims to determine whether to institute IPR.

- Skill levelSkill level petitioner adoptedDecided for petitioner
“We do not discern a material difference between the assessments of the level of skill in the art advanced by either party, nor does either party premise its arguments exclusively on its own assessment. For purposes of institution, we adopt Petitioner’s assessment, except that we delete the qualifier “at least” to eliminate vagueness as to the appropriate level of encompassing a Ph.D. degree and beyond), and does not meaningfully indicate the level of skill in the art. Petitioner’s assessment—without the qualifier—is supported by the testimony of Dr. Stavrou and it is consistent with the ’809 patent and the asserted prior art. We note, however, that our obviousness analysis would be the same under each party’s assessment.” slip op. at 9

“1. “Call” Terms (Claims 1, 8, and 15) The parties, and their respective experts, agree that “telephone call” (claim 1), “electronic call” (claim 8), and “electronic phone call” (claim 15) should be interpreted to mean “voice communication over an electronic network between at least two parties,” which was Patent Owner’s proposal in the district court case. See Pet. 16, 19 n.8, 58 (citing Ex. 1027, 9);1 Ex. 1003 ¶ 82; Ex. 2011 ¶¶ 51–53; Ex. 2016, 176:10–177:6 (Dr. Kyriakakis agreeing that “there is live voice exchange during a telephone call” (in addition to “background noise”)), 180:22–181:11 (same). Based on our review of the ’090 patent, we agree as well and adopt that interpretation for purposes of this Decision. See, e.g., Ex. 1001, col. 3, l. 1–col. 5, l. 44 (“Consider an example in which a listener sits at his kitchen table and has an electronic telephone call with his mother.”), Fig. 1. 1 When citing non-patent references, we refer to page numbers added by Petitioner in the bottom-right corner of the exhibit. Listening Person” (Claim 1) and “Sound Localization Point . . . Away From and Proximate to the First Person” (Claim 15) a) Procedural History As explained above, the parties did not propose any express interpretations in their Petition and Response. See Pet. 15; PO Resp. 3. Patent Owner argued, however, that “Petitioner and Dr. Kyriakakis misapprehend the scope and meaning of the [c]hallenged [c]laims.” PO Resp. 35–49. For example, Patent Owner argued that they “mischaracterize [c]laim 1’s scope as exclusively directed at binaural recording (but not binaural synthesis),” claim 8 “inherently us[es] binaural synthesis and HRTF processing,” and “binaural synthesis methods must be employed” for claim 15. Id. at 36, 46, 48–49 (emphasis omitted). In its Reply, Petitioner characterized the dispute between the parties as pertaining to the phrase “away from and proximate to,” where Petitioner proposed an interpretation of “a distance from” and Patent Owner allegedly was proposing “externalization of sound through HRTFs and [6 degree of freedom (6DOF)] tracking of the listener relative to the SLP that represents the talker.” Reply 2–12. Patent Owner responded in its Sur-Reply by stating that Petitioner “mischaracterizes” Patent Owner’s arguments, Petitioner “disputes constructions that [Patent Owner] never proposed,” and Petitioner’s focus on certain claim language for which Patent Owner “never proposed construction” was “misplaced.” Sur-Reply 1–2, 11. Patent Owner agreed, though, that the parties’ disagreement was “whether the claims require HRTF processing and whether [the] prior art teaches such processing.” Id. at 5; see Tr. 49:19–21 (Patent Owner agreeing that the dispute is “whether the claims require . . . processing with HRTFs”). dispute between the parties, as many of the arguments regarding claim interpretation in the parties’ papers were interspersed with discussions of the prior art, the state of the art, and related declarant testimony. Paper 56, 3–4. In particular, we requested that the parties identify “the specific claim language that allegedly does or does not require HRTF processing” and the support in the record for each party’s interpretation. Id. at 4. Patent Owner responded that all of the challenged claims “require HRTF processing” because they recite the phrase “sound localization point . . . away from and proximate to the [listener].”2 PO Supp. Br. 1 (emphasis omitted). Petitioner disagreed. Pet. Supp. Br. 1. Accordingly, we interpret that phrase as it appears in independent claims 1 and 15 and, specifically, address whether the phrase requires HRTF processing.3” slip op. at 13

“Petitioner relies on its earlier arguments regarding claim 17. Pet. 41; see Ex. 1003 ¶ 184 (citing earlier analysis of Bedingfield). Petitioner further contends that a person of ordinary skill in the art “would have been motivated to apply Ballas’s wearable frame with head tracking and HRTF processing to Bedingfield-Andrea’s headphones” to “provide[] a more realistic virtual experience,” but does not make any argument that Ballas teaches changing an ITD. Pet. 39–43; see Ex. 1003 ¶¶ 175–191. For the reasons explained above, we are not persuaded that Bedingfield teaches changing an ITD. See supra Section II.D.6. Accordingly, Petitioner has not proven, by a preponderance of the evidence, that claim 18 would have been obvious based on Bedingfield, Andrea, and Ballas under 35 U.S.C. § 103.” slip op. at 61

“exceptional remedy of striking sentences in the Sur-Reply. Patent Owner filed the deposition transcripts of Dr. Welch and Dr. Roginska “only for the limited purpose of allowing the Board to understand the context of the cross-examination” and “does not rely on the[] [e]xhibits for any substantive argument in [the] Sur-Reply.” Sur-Reply v–vi. Patent Owner does not cite Exhibits 2029 and 2030 themselves in its Sur-Reply; it only cites Dr. Kyriakakis’s deposition transcript in this proceeding. Id. We agree with Patent Owner that its arguments in the Sur-Reply are properly responsive to the Reply because they address Dr. Kyriakakis’s cross-examination testimony where he was questioned about the opinions in his reply declaration (but we do not agree with Patent Owner’s claim interpretation arguments on the merits, for the reasons explained above). See Mot. to Strike Opp. 3; supra Section II.B.2.e. We also agree, under the particular factual circumstances presented, that filing Exhibits 2029 and 2030 was proper so the Board has the full context in which to evaluate Dr. Kyriakakis’s cross-examination testimony.

“Institution of an inter partes review is authorized by statute when “the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a) (2018). Upon consideration of the Petition, the Preliminary Response, and the evidence of record, we determine that Petitioner has established a reasonable likelihood that it would prevail in showing the unpatentability of at least one claim challenged in the Petition.

- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededNot reached
“Thus, although both parties indicate that no claim construction is necessary at this stage of the proceeding, it is apparent that they disagree as to the meaning of “discrete carbon nanotubes.” While Petitioner appears to construe “discrete carbon nanotubes” as “nanotubes that are generally individually distinct” (Pet. 13), Patent Owner argues a more restricted construction requiring that “discrete carbon nanotubes” not be reacted with other components. Prelim. Resp. 3. The evidence relating to claim 10 In quotations from the Preliminary Response throughout this Decision, we have retained bolding and underlining added to the text by Patent Owner. construction that Patent Owner offers on the current record, however, does not address its proposed restriction. See id. at 9, n. 4, citing Ex. 1001, 3:9, 5:39–40 (“The ’649 Patent describes the ‘discrete carbon nanotubes’ as, for example, ‘individually dispersed’, ‘individualized carbon nanotubes’, ‘dispersed as individual nanotubes’, and ‘essentially discrete individual fibers, not entangled as a mass.’”). As discussed in Section II.D.2 below, we determine based on the record at this stage of the proceeding that Petitioner demonstrates sufficiently for purposes of institution that Sun discloses or suggests “discrete carbon nanotubes.” Therefore, we do not explicitly construe any claim terms in this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). If either party intends to argue a claim construction at trial, however, including what is the ordinary meaning of a term, they should do so in a clearly designated section of their briefing. See Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 21, 2019) (“CTPG”), 46, 49 (available at https://www.uspto.gov/TrialPracticeGuideConsolidated); O2 Micro Int’l Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351, 1361 (Fed. Cir. 2008) (“A determination that a claim term ‘needs no construction’ or has the ‘plain and ordinary meaning’ may be inadequate when a term has more than one ‘ordinary’ meaning or when reliance on a term’s ‘ordinary’ meaning does not resolve the parties’ dispute.”).

“Petitioner argues a person of ordinary skill in the art at the time of the invention “would have had at least [a] Master’s degree in materials science, chemistry, chemical engineering, a field relevant to polymer science and engineering, or the equivalent, and at least three years of experience in nanomaterials, electrochemistry, batteries, or polymer related activities.” Pet. 5 (citing Ex. 1003 ¶ 19). Petitioner further argues that “[a]dditional work experience can compensate for less formal education, and vice versa.” Id. Patent Owner does not dispute the level of ordinary skill in the art. Prelim. Resp. 4. For purposes of this decision, we adopt Petitioner’s definition of the level of ordinary skill in the art because it is consistent with the ’649 patent and the asserted prior art.” slip op. at 9
