      “We disagree with Petitioner’s arguments. Claim 1 recites “a decoy computer system [that] comprises . . . a virtual machine monitor,” and “at the virtual machine monitor: . . . creating, from the stored activities, a fingerprint.” Ex. 1001, 19:4–22. Thus, the claim’s plain language requires creating a fingerprint at the virtual machine monitor, not just at the decoy system, as Petitioner asserts. When, as here, a claim term has “ordinary, simple English words whose meaning is clear and unquestionable,” we may not redraft those words to mean something different. Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371, 1373–75 (Fed. Cir. 2004). Petitioner offers no explanation how one skilled in the art might read “at the virtual machine monitor” to mean at the decoy system, rather than at the virtual machine monitor. Although the claim’s plain language is decisive, we also disagree with Petitioner’s assertion that the ’697 patent’s specification describes only fingerprint creation outside the virtual machine monitor because, as Patent Owner explains, the specification describes fingerprint generation inside and outside the virtual machine monitor. See Sur-reply 1– 2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Claim 1’s plain language, however, only covers the latter.

Petitioner argues that the intrinsic record supports its position because “[n]owhere in the ’697 Patent is there any teaching or suggestion that a [virtual machine monitor] creates a fingerprint/signature indicative of attack activity,” and instead, “[t]he ’697 Patent teaches that its signature generation engine is separate from the [virtual machine monitor].” Reply 2 (citing Ex. 1001, 8:12–19).

      “provide sufficiently persuasive evidence in support of its position that claim 1’s “decoders” has a meaning broad enough to correspond to Zha’s decision rule. Petitioner disputes Patent Owner’s understanding of claim 1’s “decoders” by arguing that “[Patent Owner] does not argue that the specification disclaims decoders that do not perform error correction, or otherwise expressly limits the claimed bank of decoders to error correction.” Prelim. Reply 6. In support of its position, Petitioner cites Dr. Min’s testimony that “[i]n my opinion, a [person of ordinary skill in the art] would have understood that the ‘decision rule’ would be implemented using a decoder, as decoders typically make bit decisions.” Ex. 1003 ¶ 178; Pet. 59. Dr. Min does not cite any objective evidence in support of this view. Ex. 1003 ¶ 178. In response, Patent Owner marshals intrinsic evidence, along with Dr. Caire’s testimony based on objective supporting evidence. Prelim. Resp. 47–48; Prelim. Sur-Reply 5–6. For example, arguing that all embodiments disclosed in the ’703 patent use error-correcting coding, Patent Owner emphasizes the ’703 patent’s statement that “the [’703 patent’s] specification states that ‘[t]he invention is based on an iterative decoding solution that exploits error correction codes.’” Prelim. Sur-Reply 6 (quoting Ex. 1001, 25:27–29 (emphasis added by Patent Owner)). Patent Owner also cites the Abstract of the ’703 patent, which states that “[t]he present invention provides Turbo-decoding for joint signal demodulation based on an iterative decoding solution that exploits error correction codes.” Ex. 1001, code (57); Prelim. Sur-Reply 6. Patent Owner also cites Dr. Caire’s testimony that “any reasonable understanding of a decoder is one that implements an error correction coding approach.” Ex. 2001 ¶ 98; Prelim. Resp. 47. Dr. Caire cite objective evidence that supports this view. Ex. 2001 ¶ 98 (citing Ex. 2003, 3; Ex. 2004, 11; Ex. 2005, 228). Weighing the parties’ arguments and evidence, we find Patent Owner’s more persuasive than Petitioner’s. Starting with the intrinsic evidence, Patent Owner’s citation of the ’703 patent’s repeated statements that the “invention . . . exploits error correction codes” is more persuasive than Petitioner’s argument that the ’703 patent does not disclaim other approaches. Prelim. Sur-Reply 6 (citing Ex. 1001, 25:27–29, code (57)); Prelim. Reply 6. Petitioner argues that certain background documents suggest decoders may have a broad meaning, but this attorney argument warrants less weight than Dr. Caire’s testimony. Prelim.

When questioning who exactly had rights to which specific inventions of Mr. McElwain’s, Petitioner glosses over the key, undisputed fact that Mr. McElwain assigned the invention of the ’703 patent to the exact same entity to which Brommer was assigned, specifically BAESI. Ex. 2012, 2; Ex. 2011, 2. Mr. McElwain did so shortly after BAE filed Mr. McElwain’s provisional application on April 14, 2003, which both parties treat as the ’703 patent’s date of invention. Ex. 2012, 2; Ex. 2013, 1; Prelim. Resp. 32; Prelim. Reply 1. This, in combination with Patent Owner’s evidence regarding Mr. McElwain’s EPIIA and BAE’s acquisition of Lockheed Martin’s Aerospace Electronics System Business, evinces that Mr. McElwain had an obligation on April 14, 2003, to assign the invention of the ’703 patent to BAESI. Exs. 2014–2016. As Patent Owner notes, Petitioner does not advance a reason that Mr. McElwain would not have been obligated on April 14, 2003, to assign the invention of the ’703 patent to BAESI, much less provide evidence that he was not so obligated. See generally Prelim. Reply; Prelim. Sur-Reply 2. In sum, weighing the parties’ arguments and evidence, we do not find that Petitioner has a reasonable likelihood of prevailing on its position that Brommer is prior art to the ’703 patent for purposes of obviousness.

      “interview to incorporate prosecution dependent claim 2 into prosecution claim 1 and cancel prosecution dependent claim 3. See § I.F, supra. We determine that this agreement and the corresponding amendment constitutes a clear disavowal of subject matter that supports Patent Owner’s construction. Prosecution claim 2 required that the second communication frame follow the first communication frame after a SIFS (corresponding to Figure 5 of the ’122 patent), while prosecution claim 3 required that there be a SIFS and an intervening response between the first and second communication frames (corresponding to the embodiments of Figures 3 and 4 of the ’122 patent). Before the amendment, original claim 1 included both of these embodiments, but the incorporation of prosecution claim 2 into prosecution claim 1 and the cancellation of prosecution claim 3 limited issued claim 1 to only the embodiment of prosecution claim 2. Because Larsson disclosed an intervening response to the first communication frame before the second communication frame, the clear import of the amendment was to limit claim 1 to the embodiment where the second communication frame follows immediately after the SIFS in order to distinguish claim 1 from Larsson. Indeed, in the Reasons for Allowance, the examiner explained that claim 1 distinguishes over the prior art (including Larsson) because “[t]he prior art of record fails to teach or fairly suggest ‘receiv[ing] the second communication frame after a short inter frame space (SIFS) that follows the first communication frame,’” as added from prosecution claim 2. Ex. 1002, 47. If, as Petitioner argues, prosecution claim 2 was broad enough to cover the embodiment of prosecution claim 3, then the amendment would have served no apparent purpose. Thus, we agree with Patent Owner that “[t]here is no other plausible explanation for why, when faced with Larsson’s disclosure of an intervening response, the Examiner initiated an interview to incorporate the SIFS limitation of dependent claim 2 into claim 1, and cancel dependent claim 3, which, like Larsson, included an intervening response.” See Prelim.

      “However, Petitioner does not sufficiently explain where Rao teaches “allow[ing] or disallow[ing]” as recited in claim 1. See Pet. 13–18, 25–30. To the extent Petitioner and Dr. Bims cite to Rao, they reference paragraphs 191 through 193, which discuss how Rao’s filter 322 is used to implement prioritization. See Pet. 15; Ex. 1003 ¶ 65. More specifically, those paragraphs recite using prioritization to place the network packets in different queues based on their priority. See Ex. 1005 ¶¶ 191–193. We see nothing in Rao that teaches or suggest that the network packets would be disallowed, as opposed to simply delayed, based on priority. Id. And, as Patent Owner argues, this finding is consistent with factual findings made by a different panel considering the teachings of Rao in an inter partes review of a related patent. See Prelim. Resp. 16–18 (citing Samsung Elecs. Co v. Headwater Research LLC, IPR2023-01361, Paper 8 (PTAB Mar. 29, 2024) (Decision Denying Institution)). Even if one reads the Petition as arguing that a person having ordinary skill would have modified Rao to include Araujo’s blocking—which we do not—we would not be sufficiently persuaded by that argument. Although Petitioner explains why a person having ordinary skill in the art would want to consider power usage along with whether the application is in the foreground or background, Petitioner does not explain why a person having ordinary skill in the art would have changed prioritization to blocking. See Pet. 13–18. Indeed, such a modification appears to be one that would render Rao “inoperable for its intended purpose.” In re Gordon, 733 F.2d 900, 902 (Fed. Cir. 1984).” slip op. at 18

      “identifies and refers to a valid region of the integrated circuit memory device as having a three-dimensional boundary delimited by phase ranges in command/address signals, data signals, and sampling signals. Nowhere does the ’835 patent specification indicate a valid region of the integrated circuit device as a whole can be represented by values for less than three parameters x, y, and z, all together, e.g., the command signals, the data signals, and the sampling signals. Also, the ’835 patent describes that the purpose of determining the boundaries of a valid region is to configure an optimal operating point for the integrated circuit device. Ex. 1001, 5:48–51. We have also considered other language in the claims. Each of independent claims 1 and 7 requires adjustment of the phase of all three command signals, data signals, and sampling signals, to determine the “valid operation range.” Ex. 1001, 6:56–7:4, 7:18–34. Each of independent claims 12, 20, and 23 requires adjustment of the phase of all three command signals, data signals, and sampling signals, to determine the “valid operating range.” Ex. 1001, 7:46–60, 8:28–44, 8:62–10:4. Based on the foregoing, the specification informs us that “valid operation range” is a three-dimensional range. We recognize that the specification does not expressly exclude a two-dimensional range or multiple two-dimensional ranges from being a “valid operation range” of the integrated circuit device. However, that is why we construe the claims to determine what, if anything, may be required despite a lack of express recitation in the claims.” slip op. at 17

      “for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:42–45. The preamble of independent claim 9 similarly recites “a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions.” Id. at 14:4–7. Petitioner, however, contends that “this claim term is not part of the preamble” and that “the preamble is [only] ‘In a multi-user detection system in which interfering signals are purposely allowed to exist.’” Pet. 14. Regardless, Petitioner further contends, to the extent there is any argument that that recitation is part of the preamble, “it is limiting at least because it provides antecedent basis to the ‘parameter estimation unit’ and ‘associated channel transfer functions’ terms that are used in the remainder of the body of the claims and is ‘essential to understanding the structural limitations’ of the parameter estimation unit.” Id. Apart from arguing that the recited “parameter estimation unit” is limiting, Petitioner does not propose any id. Patent Owner does not respond to Petitioner’s contentions and also does not argue that any construction is necessary for the parameter estimation unit. See generally Prelim. Resp. As reproduced in Section II.D. above, the preamble of claim 1, in its entirety, recites, “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:41–45. The preamble of claim 9 is similar. Id. at 14:3–7 (reciting “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions”). The body of each claim recites the elements of the recited “parameter estimation unit,” namely, “a signal processor for determining said channel transfer functions for each received signal” and “means . . . for providing uninterrupted estimates of the channel transfer function parameters on a real-time basis . . . .” The phrase “In a multi-user detection system in which interfering signals are purposely allowed to exist” provides additional context for the environment in which the parameter estimation unit is intended to operate. Whether the preamble is limiting is a question that we do not need to decide here, however. Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.
