      “On this record, we agree with Petitioner. Patent Owner, in contending that Park’s hybrid CSI signal does not describe two signalings, does not address Petitioner’s mapping of the claimed “first signaling” and the claimed “second signaling.” Petitioner persuasively maps the claimed “first signaling” to Park’s hybrid CSI signal (Pet. 21), and persuasively maps the claimed “second signaling” to Park’s DCI format signal (Pet. 30). Patent Owner does not explain why Park’s DCI format signal does not describe the claimed “second signaling.” On this record, we are sufficiently persuaded by Petitioner and Dr. Akl that Park’s DCI format signal, which triggers the UE to perform aperiodic CSI reporting, describes a “second signaling . . . used to determine the Q2 antenna port(s)” as recited in limitation 1.6.

Pet. 59 (citing Ex. 1003 ¶ 71). Petitioner also contends that adding Shin’s CSI request field to the DCI format signal of Park is the combination of familiar elements according to known methods that yields a predictable result, and that the combination uses Shin’s known technique of including a CSI request field in a DCI format signal to improve Park’s DCI format signal in the same way.

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Patent Owner does not address the level of skill. See Prelim. Resp. Because Petitioner’s proposed level of ordinary skill in the art is consistent with the field of the invention of the ’275 patent and not disputed by Patent Owner, for purposes of this Decision, we adopt Petitioner’s formulation of the person having ordinary skill in the art.7 7 If Patent Owner disagrees with this formulation of the level of skill in the art, it must raise that disagreement in its Response. If a different level of skill would affect the outcome in this case, the parties must brief that issue as well. The failure of Patent Owner to describe how a different level of skill in the art is determinative will be a forfeiture of that argument. If there is a dispute regarding the level of ordinary skill in the art, then the parties are also encouraged to submit evidence, other than conclusory expert testimony, that supports their position.

    • BurdenDecided for petitioner

      “The record at this stage sufficiently supports Petitioner’s argument that Foster’s receiver 430 stores content that it receives. Pet. 65 (citing Ex. 1006 ¶¶ 4, 8, Fig. 8). According to Dr. Rubin’s annotations, receiver 430 can be a personal computer (PC) or set-top box. Ex. 2003 ¶ 83 (labeling the receiver in Figure 16 as such). This is consistent with Foster. Ex. 1006 ¶¶ 49, 51 (describing PC 18 and a set-top box). Foster describes how the receiver stores encrypted content. See id. ¶¶ 8, 79. For example, Foster explains, “Once received, recipient 430 can then synchronously store the encrypted content.” Id. ¶ 79, cited in Pet. 68–69. According to Foster, “The encrypted title key is then attached to the content packet and the header for synchronized transmission to, or storage by a receiver.” Id. ¶ 8 (emphasis added), quoted in Pet. 65. For at least the reason that Foster teaches a PC or at this stage that Foster’s data set is “for storage.” See Pet. 65–66, 80–82. At this stage, we credit Dr. Bhattacharjee’s testimony (Ex. 1003 ¶¶ 221–222) over Dr. Rubin’s (Ex. 2003 ¶¶ 108–109) because it is better supported by the current record. In particular, we see no support for Dr. Rubin’s testimony that Foster’s receiver cannot provide long-term storage or is unlike the ’854 patent’s storage devices. See Ex. 2003 ¶¶ 108– 109. For instance, we see little difference between Foster’s PC 18 and the magnetic or optical disk, USB key drive, or other devices that Dr. Rubin claims are long-term storage devices. Ex. 1001, 67:16–19, cited in Ex. 2003 ¶¶ 108–109. PC 18 has “data storage.” Ex. 1006 ¶ 75. Foster explains “optical media” or “magnetic media” are types of data storage. Id. Foster also states that the receiver stores data. Id. ¶ 8. In view of these parts of Foster, we credit Dr. Bhattacharjee’s testimony that Foster’s receiver has data storage (Ex. 1003 ¶¶ 221–222) over Dr. Rubin’s testimony that Foster’s devices are unlike those described in the ’854 patent (Ex. 2003 ¶¶ 108–109), at this stage.” slip op. at 17

Petitioner also asserts that a “higher level of education may substitute for less experience.” Id. Patent Owner does not respond to Petitioner’s assertions or argue for a definition of a person of ordinary skill in the art. See Prelim. Resp. Here, we apply the skill level proposed by Petitioner.

      “key (the encryption operation Petitioner contends would be reordered/repeated).” Id. at 16. Dr. Rubin explains why reordering the steps in the way that Petitioner proposes would have been pointless: Indeed, a [person of ordinary skill in the art] would recognize that encryption with the alleged external key would not be an appropriate step to repeat or reorder because it is parsed along with the data set into portions and those portions are then encrypted. Consequently, encrypting the shares with the alleged external key (i.e., the session master key) would render the splitting and encryption of the alleged external key pointless. Ex. 2003 ¶¶ 52–53. Dr. Bhattacharjee does not fully explain why the key that is parsed and encrypted is then used to further secure the data. Ex. 1003 ¶¶ 110–111. Thus, we credit Dr. Rubin’s testimony (Ex. 2003 ¶¶ 52–53) over Dr. Bhattacharjee’s (Ex. 1003 ¶¶ 110–111) on this issue. For this additional reason, Petitioner has not shown that Orsini discloses the Different-Order Version. See Pet. 33–35.” slip op. at 29

      “review. 35 U.S.C. § 314(b) (2018); 37 C.F.R. § 42.4(a) (2023). We may not institute an inter partes review “unless . . . 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). The “reasonable likelihood” standard is “a higher standard than mere notice pleading” but “lower than the ‘preponderance’ standard to prevail in a final written decision.” Hulu, LLC v. Sound View Innovations, LLC, IPR2018-01039, Paper 29 at 13 (PTAB Dec. 20, 2019) (precedential). When instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim. 37 C.F.R. § 42.108(a). Applying those standards, and upon consideration of the information presented in the Petition and Preliminary Response, we determine that Petitioner has demonstrated a reasonable likelihood of success in proving that at least one claim of the ’609 patent is unpatentable. See 35 U.S.C. § 314; 37 C.F.R. § 42.4(a). Accordingly, we institute an inter partes review as to all Challenged Claims of the ’609 patent on all grounds raised in the Petition.” slip op. at 2

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “In determining the level of ordinary skill in the art, various factors may be considered, including the “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 Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citation omitted). The level of ordinary skill in the art also may be reflected by the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Neither party argues, at least at this stage of the proceeding, that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’609 patent, the background technical field, the prior art, and Petitioner’s proposed and unopposed definition of the skilled artisan, we apply the level of skill set forth above, which is consistent with the testimony of Dr. Bhattacharjee (Ex. 1003 ¶¶ 37–38).” slip op. at 9

      “repeated, would not necessarily indicate that the chunks, each encrypted with a separate share key, would be again encrypted using the session master key (the cryptographic operation Petitioner contends would be reordered/repeated).” Prelim. Resp. 16. Dr. Rubin explains why reordering the steps in the way that Petitioner proposes would have been “pointless:” Indeed, [the skilled artisan] would recognize that encryption with the alleged first key would not be an appropriate step to repeat or reorder because it is parsed along with the data set into portions and those portions are then encrypted. Consequently, encrypting the shares with the alleged first key (i.e., the session master key) would render the splitting and encryption of the alleged first key pointless. Ex. 2003 ¶¶ 52–53. Dr. Bhattacharjee does not fully explain why the key that is parsed and encrypted is then used to further secure the data. Ex. 1003 ¶¶ 101–105. Thus, we find Dr. Rubin’s testimony (Ex. 2003 ¶¶ 52–53) more persuasive than Dr. Bhattacharjee’s (Ex. 1003 ¶¶ 101–105) on this issue.

      “Here, however, Petitioner does not insist any construction is incorrect. Rather, Petitioner presents alternative rationales for why the claims are unpatentable, stating that the Petition demonstrates “unpatentability regardless of which proposed construction is correct.” Pet. 9. Even though some stated rationales are based on Patent Owner’s constructions in the District Court Case, the Petition complies with the rule because it explains how the Challenged Claims are to be construed under the alternative challenges. See 37 C.F.R. § 42.104(b)(3). The rule “does not require Petitioner to express its subjective agreement regarding correctness of its proffered claim constructions or to take ownership of those constructions.” Western Digital Corp. v.

      “With respect to the claim term “content-related . . . data segments,” the specification states that “the term “content-related” is understood to mean that first and second data segments have a syntactical meaning . . ., such as e.g. a plurality of succeeding second data segments represent the speech signal of a specific speaker within a dialog sequence.” Ex. 1001, 4:9–22 (emphasis added).7 We agree with Patent Owner that the emphasized sentence defines the term “content-related.” Prelim. Resp. 14– 15.8 However, for reasons similar to those discussed in the final written decision in IPR2022-01086, Paper 37 at 15–19, we determine that the “content-related” data segments do not support Patent Owner’s proposal, 7 The ellipses represents omission of the phrase “within the respective data file” because, as discussed above, we need not decide if the preamble (which introduces the data files) is limiting with respect to requiring data files. As discussed below, Petitioner’s showing includes relying on separate data files in Comps. 8 We also recognize that whether two segments have “syntactical meaning” between them may be somewhat subjective as discussed in the analysis of Petitioner’s challenges below. namely “data segments ordered in a file such that they will present the file’s contents in their intended presentation order when rendered sequentially.” See Prelim. Resp. 14; IPR2022-01086, Paper 37 at 15–18. Contrary to Patent Owner’s arguments, the “syntactical meaning” as disclosed in the specification does not require “a sequential, chronological nature” specified by the content relationship, because claims 1 and 9 separately recite that feature by requiring “outputting . . . the content-related first data segments and the content-related second data segments according to their chronological sequence.” See Prelim. Resp. 17 (agreeing that “[i]ndependent claims 1 and 9 require outputting the data segments “sequentially” and “according to their chronological sequence.”).

Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)); see also 37 C.F.R. § 42.104(b) (2019) (requiring a petition for inter partes review to identify how the challenged claim is to be construed and where each element of the claim is found in the prior art patents or printed publications relied upon). A claim is unpatentable under 35 U.S.C. § 103(a) if “the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of skill in the art; and (4) when in evidence, objective evidence of obviousness or nonobviousness, i.e., secondary considerations.5 See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). An obviousness analysis “need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.” KSR, 550 U.S. at 418. Additionally, the obviousness inquiry typically requires an analysis of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2016) (requiring “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)). Furthermore, Petitioner does not satisfy its burden of proving obviousness by employing “mere conclusory statements,” but “must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016).” slip op. at 11

      “To resolve this controversy, we turn to the decision in Hulu, LLC, v. Sound View Innovations, LLC, IPR2018-01039, Paper 29 (PTAB Dec. 20, 2019). In Hulu, the Board issued a decision denying institution of an inter parties review because the Board found that a petitioner failed to sufficiently show that a reference qualified as a printed publication. Id. at 2. The Board’s Precedential Opinion Panel (POP) ordered a review on rehearing to address the issue of what is required for a petitioner to establish that an asserted reference qualifies as a “printed publication” at the institution stage. Id. The POP determined that the statutory “reasonable likelihood” standard for institution applies to the issue of whether a reference is a printed publication. Id. at 13. The POP “explained that it is a higher standard than mere notice pleading, but, . . . it is lower than the ‘preponderance’ standard to prevail in a final written decision.” Id. In Hulu, Patent Owner argued that “the reasonable likelihood standard is satisfied only when a petitioner presents its ‘case in chief’ in the petition, including all evidence that will be used in any instituted review, with a few limited exceptions.” Id. at 11. The POP, however, determined that “[w]hile the petitioner must submit evidence sufficient to meet the reasonable likelihood standard, some limited opportunities exist for the petitioner to present new evidence later, including: (1) in a reply to a patent owner preliminary response; (2) in a reply to the patent owner response; and (3) in a motion to file supplemental information.” Id. at 14. The POP explained that, for example, “if the patent owner challenges a reference’s status as a printed publication, a petitioner may submit a supporting declaration with its reply to further support its argument that a reference qualifies as a printed publication.” Id. at 15. The POP also explained that, if a patent owner does not challenge the reference’s status as a printed publication, the petitioner may move to submit the declaration through the supplemental information process.

      “Patent Owner contends that Basturk teaches away from providing authentication as an application protocol on an application layer because Basturk discloses that the presence of application level security features does not necessarily imply the security of delivery, which shows the need for security at the transport layer. Prelim. Resp. 43–53. However, Basturk discloses that application level security features are provided by application level security. Ex. 1006, 3. For example, Basturk discloses guaranteeing integrity by signing the data before passing it to the transport level. Id. at 3– 4. Basturk further discloses “a method to transform any transport protocol into a ‘secure’ version, equipped not only with the new security features discussed above, but providing, at least as options, the standard application level security features.” Id. at 5. At this stage, we are sufficiently persuaded that Basturk teaches providing standard application level security features such as authentication. Patent Owner contends that on-the-fly processing as taught by Basturk is not enabled by the use of a trailer. Prelim. Resp. 52–55. Basturk discloses computing signatures as data transmission proceeds, to achieve the goals of avoiding slowing down the regular flow of data, and allowing the possible off-load of signature computations. Ex. 1006, 7, 12. Basturk discloses that the signature of an outgoing packet is computed after data encryption, which complies with the requirement that the signature is computed “on-the-fly.” Id. at 14. Dr. Houh testifies that computing the signature “on-the-fly,” as data is being transmitted, provides the benefits of faster data transmission, reduced jitter, and reductions in computing power. Ex. 1003 ¶ 64. Dr. Houh testifies that calculating the signature of Handley’s RTP packet “on-the-fly” and placing the signature at the end of the packet as taught by Basturk yields the benefit of transmitting data while computing the signature, which minimizes latency as taught by Basturk. Id. ¶ 85. At this stage, we are sufficiently persuaded that a person of ordinary skill would have placed the authentication information of Handley’s RTP packet at the end of the packet as taught by Basturk to yield the benefits of faster data transmission, reduced jitter, and reductions in computing power. Accordingly, for purposes of this Decision, we are persuaded that Petitioner cites sufficient evidence to support its contention that a person of ordinary skill would have had reason to combine the teachings of Handley and Basturk.” slip op. at 20

      “Dr. Houh further testifies that, given the remaining choices of placing the authentication data at the beginning or the end of the payload data, a person of ordinary skill would have recognized that placing the authentication data at the end of the payload data would reduce latency because this allows the packet to be transmitted while the authentication data is calculated. Ex. 1003 ¶ 178. To support this testimony, Dr. Houh relies on other protocols that use integrity checks, such as the Frame Check Sequence located at the end of an Ethernet Frame. Id. (citing Ex. 1014). We are sufficiently persuaded at this stage, based on Dr. Houh’s testimony and supporting evidence, that a person of ordinary skill would have placed the authentication data at the end of the whole RTP packet payload as claimed. Further, on this record, given the choice between placing authentication data at the beginning, middle, or end of the packet, we are sufficiently persuaded that it would have been obvious to place the authentication data at the end. See KSR, 550 U.S. at 421 (“When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp.

      “Figure 6 of Rauhala has been annotated by Patent Owner to show that the parallel connection (outlined in red) including resistors R1, R2. R3 and switches ka, kb is outside the signal path (highlighted in yellow) through differential amplifier 61. Prelim. Resp. 38. Petitioner identifies R1, R2, R3 and switches ka and kb as the claimed variable impedance. See, e.g., Pet. 39–41. The Petition (and the supporting Baker Declaration) do not explain adequately how, under this interpretation by Petitioner and its expert, Rauhala meets the adjusting an impedance “in the signal path” limitation. See Prelim. Resp. 39–41. For the reasons given, therefore, even if we were to disagree with Patent Owner’s construction of “impedance,” we agree with Patent Owner that Petitioner fails to demonstrate sufficiently that Rauhala meets the limitation in claims 7 and 19 requiring “dynamically adjusting one or more of an impedance . . . in the [receiver] signal path.” For the reasons given, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing on its challenge to claims 11 and 13 as anticipated by Rauhala.

      “We disagree. Noting in the language of the claims requires that these method steps be performed by separate components, or that these method steps “provide two different channel indications at once” (Prelim. Resp. 38), only that they be performed as stated in the claim. In that respect, this case is distinguished from In re Robertson, where the Federal Circuit determined that the “third fastening means” required by the claims was not inherently disclosed by the prior art. Robertson, 169 F.3d at 745 (“The [prior art] patent does not expressly include a third fastening means for disposal of the diaper, as claim 76 requires.”). In further contrast to this case, Robertson addressed mechanical elements of a product (fasteners for disposable diaper), not steps in a process. More pertinent to our facts is the Federal Circuit’s decision in Microsoft Corporation v. Uniloc, 2017 LLC, No. 2021- 2039, 2022 WL 11531235 (Fed. Cir.

Circuit concluded that the Board had misconstrued the claims to require separate acts: We agree with [petitioner] that the Board misconstrued the claims to require that the comparing and determining step are performed by two separate acts in a certain order. Nothing in the intrinsic record requires such a narrow construction, and neither party presented this construction to the Board. Without any such evidence, we decline to impose such a narrow claim construction. Microsoft Corp., 2022 WL 11531235, at *3 (citation and footnote omitted).

      “We are persuaded, on the present record, that both Petitioner’s and Patent Owner’s proposals are consistent with the problems and solutions in the ’825 patent and prior art of record.

On balance, Petitioner’s proposal of education plus a minimum of two years of experience is a better reflection of the level of skill in the prior art. For example, Rauhala presents functional block diagrams of signal strength information. See, e.g., Ex. 1004, Figs. 1–5, ¶¶ 15, 17, 19, 21. Similarly, Masaaki’s Figure 1 shows “a circuit block diagram of a reception unit 40 of a pager” according to an embodiment of the invention. Ex. 1005, 5:3–4. The block diagram shows various components, including an antenna, amplifiers, bandpass filters, a mixer, an oscillator, and a detection circuit. Id. at 5:5–8, Fig. 1.

      “strength indicator circuits 440 and 450, the written description unambiguously discloses that each circuit determines the cumulative signal level of the desired signal and the interfering signals. Neither circuit determines only the signal strength of the interferer signals, nor does a circuit determine only the signal strength of the desired signal. In other words, the written description does not support a limited reading of the claim language so as to require two separate circuits—one circuit for determining a a signal strength of the desired signal. Thus, based on this preliminary record, we do not construe the circuit limitation as requiring the wireless transceiver necessarily to have two circuits, one circuit for determining a signal strength of the interferer signal and a different circuit for determining a signal strength of the desired signal, because, under that reading of the claim, the only embodiment in the written description would not fall within the scope of the claim. It is well-established that “[s]uch an interpretation is rarely, if ever, correct and would require highly persuasive evidentiary support,” which is not present in this record as discussed below.

      “As explained above, however, on this preliminary record, we do not interpret the circuit limitation to impose a timing requirement such that the determining has to occur at precisely the same time. Nor at this preliminary juncture do we read a precise timing requirement into the circuit limitation based on written description disclosure that the desired signal and the interferer signal are part of the received signal input spectrum. As explained above, for example, the written description describes a circuit providing a cumulative signal level corresponding to the sum of the desired and interfering signals. Ex. 1001, 6:59–67. As such, the written description describes making the determinations on two signals that are part of the received signal input spectrum. Patent Owner argues that Rauhala does not disclose “two determinations of two different signal strengths together.” Prelim. Resp. 40. We do not agree with Patent Owner on this preliminary record. Rauhala’s disclosure of providing control bits based on the comparisons of the signal strengths to respective thresholds, discussed above, also undermines Patent Owner’s argument that detector DET, which (i) provides one or the other and (ii) needs to be re-tuned to read the other signal, cannot anticipate the claim. Notably, for example, Rauhala discloses setting control bits based on comparisons of the respective signal strengths to thresholds: cM. Signal cA is 0 when signal RSS is greater than S4 and signal RSSn is at the same time smaller than Sn. Otherwise, signal cA is 1. Signal cA is taken to amplifiers Al and A2. Signal cM is 1 when signal RSS is not greater than S4 and signal RSSn is at the same time at least Sn. Ex. 1004 ¶ 17 (emphases added). Here Rauhala describes providing control signals based on the strength of both signals from the receive and neighboring channels, which undermines Patent Owner’s arguments.” slip op. at 25
