The Federal Circuit rendered its Decision on October 6, 2023 (Paper 58) and entered its mandate on November 29, 2023 (Paper 57). In its Decision, the Federal Circuit vacated our conclusion regarding the “means for detecting” limitation recited in claims 5 and 10. Sisvel, 82 F.4th at 1364, 1370. The Court ordered that, on remand, we “must conduct the analysis appropriate for Noah group two, including whether any of the protocols are clearly linked or associated with ‘the function recited in the claim,’[ ] and whether they are ‘adequate structure for performing this function.’” Id. at 1370 (citing Noah Systems, Inc. v. Intuit Inc., 675 F.3d 1302, 1313 (Fed. Cir. 2012)). The Court further held that “the Board should have considered the knowledge of a skilled artisan,” and specifically, Dr. Kakaes’s expert testimony, “to assess whether the protocol name sufficiently discloses an understood algorithm corresponding to the means-plus-function limitation.” Id. at 1369. The Court also held that we “must either (1) determine whether the claim[s] [are] indefinite and then whether such indefiniteness renders it impossible to adjudicate a prior-art challenge on the merits, or (2) resolve the prior art challenge to the patentability of the claims despite the potential indefiniteness of the means-plus-function term.” Id. at 1370. After the Federal Circuit issued its mandate, we ordered the parties to brief these issues including “the supported construction of the ‘means for detecting’ claim term, as well as the attendant patentability issues of indefiniteness and impossibility as relevant to this claim term.” Paper 59, 3.

“In its Patent Owner’s Response, Patent Owner states: [A] person having ordinary skill at the time of invention— September 10, 1999—in the relevant art would be one with a bachelor’s degree in electrical engineering or computer sciences and telecommunications networks, along with at least three or more years of practical experience in the field. A combination of more experience in the field and less education or more education and less experience in the field would also suffice. PO Resp. 7 (citing Inst. Dec. 9; Ex. 2001 ¶ 27). In our original Final Written Decision, we determined that: Although there are differences between the contentions of the parties as to the level of ordinary skill in the art, the parties have not informed us of a dispute that needs to be resolved. We do not find it necessary to resolve the differences between the contentions of the parties as to the appropriate level of ordinary skill in the art because the findings and conclusions rendered in this Decision do not turn on either proposed definition. We determine, on this record, that the level of ordinary skill proposed by Patent Owner is consistent with the ’561 patent and the asserted prior art. As such, we adopt Patent Owner’s proposed definition for a person of ordinary skill in the art. Final Dec. 10. Based on our review of the entire record, we are not apprised of nor can we ascertain any reason to deviate from this determination.

Accordingly, the rules governing this inter partes review require that Petitioner “identify the specific portions of the specification that describe the structure, material, or acts corresponding to each claimed function.” 37 C.F.R. § 42.104(b)(3).

“For example, with respect to the CRC protocol, Dr. Kakaes testifies that “CRCs are often referred to as ‘error detecting codes’ as they are typically used[] to detect whether a received data message is or is not erroneous.” Ex. 1002 ¶ 88. Dr. Kakaes further testifies that [t]o use a CRC, the transmitter runs a polynomial division of the data block (before forward error correcting code has been applied, if any) to calculate a “remainder” consisting of a predetermined number of bits, for example 16, which are also called “parity bits,” or “check bits,” or “checksum bits,” or “CRC bits” that are attached to the block to be encoded and then transmitted, in whichever way it may or may not be encoded, punctured, etc. After reception and channel decoding (recall that means determining the “maximum likelihood” message), the receiver then runs the same polynomial division of the received decoded data block (which includes the parity bits) and, if the result does not match the “remainder,” i.e., the “parity bits” are not consistent with the determined message, the decoded data block “fails” the “check,” i.e., is declared as being erroneous. As it turns out such a determination is never wrong. In other words, the “false negative” rate is 0. Id. (emphasis added).

“Patent Owner’s expert, Dr. Goodrich, proposes what Patent Owner characterizes as “a somewhat different level,” namely “an individual with at least a bachelor’s degree in Computer Science or related area and two years of experience developing software tools and/or computer systems for use in the area of audio or video creation, encoding, and/or distribution.” PO Resp. 13; Ex. 2007 ¶ 50. Although we agree that the respective articulations are “somewhat different,” they are generally similar, and our Decision does not depend on nuanced distinctions regarding the level of ordinary skill. Indeed, Dr. Goodrich describes his proposed articulation as “approximate,” such that “more work experience could compensate for less education or more education could compensate for less work experience.” Ex. 2007 ¶ 50. Because we find Petitioner’s proposal reasonable, consistent with the level of skill reflected by the prior art, and supported by Dr. Freedman’s testimony, we adopt it for this Decision.

- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for patent owner
“We agree with Patent Owner’s contention that the emphasized sentence defines the term “content-related.” See PO Resp. 15–16 (Patent Owner arguing that “[t]here are thus three strong indications of lexicography: (1) ‘content-related’ is set off by quotation marks; (2) the patentee used the word ‘is’ to describe the term ‘content-related’; and (3) the patentee states what ‘content-related’ is ‘understood to mean.’” Nor does Petitioner disagree that the sentence is definitional. See Tr. 8:15–16 (referring to the “term content-related as it’s defined in the specification”). Indeed, in the Starz litigation, the district court also treated the sentence as definitional, a fact that we find significant as a matter of comity. See Ex. 1018, 111:24–112:1 (district court judge stating at Markman hearing, “I’m going to adopt . . . the express definition provided in the specification”). But like the district court, we discern insufficient reason to adopt the additional gloss that Patent Owner seeks to apply to the definition of “content-related.” That is, Patent Owner proposes that we additionally construe the phrase “syntactical meaning” within the definitional statement to arrive at Patent Owner’s proposed construction. PO Resp. 16–20. According to Patent Owner, “[t]he specification makes clear, through its use of consistent and repeated examples, that ‘syntactical meaning’ requires a specific relationship between the data segments within a data file: succeeding data segments within a data file must be ordered so as to present the content in its intended sequence when rendered.” Id. at 17 (citing VirnetX Inc. v. Cisco Sys., Inc., 767 F.3d 1308, 1317–19 (Fed. Cir. 2014); Alloc, Inc. v. ITC, 342 F.3d 1361, 1368–71 (Fed. Cir. 2003)). Patent Owner adds that the claims, the context provided by the problems solved by the ’794 patent, and the cross-examination testimony of Petitioner’s expert, Dr. Freedman, all support this additional aspect of Patent Owner’s proposed construction. Id. at 18–20. Relying on additional direct testimony by Dr. Freedman, Petitioner counters this position as “improperly import[ing] limitations from the specification that are not required by the claims” and “render[ing] other portions of claim 1 superfluous.” Reply 3 (citing Ex. 1016 ¶ 22); see Tr. 10:18–20 (Petitioner explaining at oral hearing that “the syntax information is simply just identification information which is used to find out what the order of the files is. But the identification information does not by itself indicate the order. It’s just an identifier.”). We agree with Petitioner that it would be imprudent to adopt Patent Owner’s additional gloss because, “[w]hile claims must be construed in light of the specification, . . . limitations from the specification are not to be read into the claims, . . . for ‘[i]t is the claims that measure the invention.’” Golight, Inc. v. Wal-Mart Stores, Inc., 355 F.3d 1327 (Fed. Cir. 2004) (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 (Fed. Cir. 1985) (other citations omitted). It is apparent that the Applicant for the ’794 patent understood how to define terminology recited in the claims, but chose to limit its definition of “content-related” in terms of the broader phrase “syntactical meaning” rather than through narrower specific reference to presentation order. In addition, claims 1 and 9 already specify “sequentially outputting the first and second data segments according to their chronological sequence,” which supports Petitioner’s observation that requiring an additional sequential order to “content-related . . . data segments” renders other portions of claim 1 superfluous.

“As a basic principle of claim interpretation, prosecution disclaimer promotes the public notice function of the intrinsic evidence and protects the public’s reliance on definitive statements made during prosecution.” Omega Engineering, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed Cir. 2003) (citing Digital Biometrics, Inc. v. Identix, Inc., 149 F.3d 1335, 1347 (Fed. Cir. 1998)) (emphasis added). As such, a statement during prosecution qualifies as a disavowal of claim scope only if it is “so clear as to show reasonable clarity and deliberateness” and “so unmistakable as to be unambiguous evidence of disclaimer.” Id. at 1325 (citations omitted). “Consequently, for prosecution disclaimer to attach, [Federal Circuit] precedent requires that the alleged disavowing actions or statements made during prosecution be both clear and unmistakable.” Id. at 1325–26. “The party seeking to invoke prosecution history disclaimer bears the burden of proving the existence of a clear and unmistakable disclaimer that would have been evident to one skilled in the art.” Mass.

“We do not agree with Patent Owner that Petitioner’s showing uses the same sound data to teach the “first sound data” of limitation 1.a and the “second sound data” of limitation 1.c. Patent Owner is correct that Rosenberg’s claim 5 describes the determination of a volume threshold based on the volume of the ambient audio signal in which characteristic form(s) (e.g., the name of the user of the media player) are present. Ex. 1006, 13:66–21, 14:28–30. However, the Petition describes using Fu’s “predetermined threshold” in combination with Hart-787’s device, which attenuates audio output of a device upon detecting a user’s utterance intended to gain the attention of the device, in order to “include adjusting the audio output volume of a wirelessly-linked audio-producing device when the voice-controlled device determines that the ambient noise level at the time a Ex. 1004, 2:22–37, 5:61–6:10, 9:18–25; Ex. 1005 ¶¶ 24, 32, 54; Ex. 1003 ¶¶ 88–89). Petitioner further proposes including a threshold that is advantageously based on the environment in which the device is operating as described in Fu, for example to respond to differing levels of noise at different times of day. Id. at 26, 29–30, 40 (citing Ex. 1006, 10:42–67, 14:28–30; Ex. 1003 ¶¶ 48–53, 55, 58, 87, 91, 107–109). We agree with Petitioner that Patent Owner’s arguments address the references individually instead of addressing the combination of the teachings proposed in the Petition. See Pet. Reply 8, 13–14; see also Dec. on Inst. 21–22, 23–24, 25–26. The Petition relies upon a combination of elements of Hart-787 with the predetermined threshold as taught in Fu and with establishing such a threshold based on the operating environment of a device as in Rosenberg. Pet. 26–31, 34–41. Patent Owner is correct that Rosenberg’s threshold is set at the time of the utterance in Rosenberg’s claim 5 and cites Petitioner’s declarant as “conceding” issues regarding how “Rosenberg’s volume threshold is determined.” PO Resp. 20–21. But this argument and the ostensible concession do not squarely address the proposed combination, which combines Fu’s teaching of an adjustment unit that “compares the volume of the ambient noise received . . . to a predetermined threshold” with Rosenberg’s teaching that such “a threshold may be ‘determined based on the volume of [an] ambient audio signal.’” Pet. 39, 40 (emphasis omitted) (quoting Ex. 1006, 14:28–30). While Patent Owner argues that “Petitioner has not proposed using a predetermined/pre-set threshold or a previously established threshold based on environmental noise in the combination of Hart-787 with F[u] and Rosenberg” (PO Resp. 46), we find, on the contrary, that the Petition describes a combination based predetermined threshold” and on a threshold “determined according to an environmental noise level.” Pet. 29–30. Thus, we find Petitioner’s unpatentability grounds do not suffer from the issues Patent Owner argues are a consequence of the purported use of the same sound data for the “first sound data” of claim limitation 1.a and for the “second sound data” of claim limitation 1.c. We do not agree with Patent Owner’s arguments regarding Fu’s teachings with respect to limitation 1.e’s “transition from a first state having a first volume level to a second state having a second volume level that is less than the first volume level” because these arguments similarly do not address the proposed combination. See PO Resp. 26–30. The Petition cites Hart-787 for attenuating the volume of an audio-producing device when a wake word is issued. Pet. 32–34, 43–44. The Petition cites Fu for adjusting volume of an audio-producing device if the level of ambient noise exceeds a predetermined threshold. Id. at 36–39, 44–45. Thus, even if Fu teaches only increasing the volume of an audio-producing device if the predetermined threshold is exceeded, the Petition relies on the combination of teachings of Hart-787 and Fu, and Patent Owner’s argument that neither reference teaches “decreasing a controllable appliance’s volume output when a previously established volume threshold is exceeded” (PO Resp. 30) does not address the combination proposed. Patent Owner’s argument that “Petitioner has not proposed modifying Fu to decrease a controllable appliance’s volume output when a volume threshold is exceeded” (PO Resp. 30) similarly does not address the combination proposed in the Petition.

Moreover, in determining that Petitioner’s additional evidence directed at RemoteCentral.com is properly considered, we are further mindful of the Federal Circuit’s endorsement that “the petitioner in an inter partes review proceeding may introduce new evidence after the petition stage if the evidence is a legitimate reply to evidence introduced by the patent owner.” Anacor Pharm., Inc. v.

We therefore do not reach the issue of whether presence on either the Radio Shack web site or on hifi-remote.com is an improper new theory raised by Petitioner in its Reply.

In the present proceeding, even assuming, arguendo, that the record sufficiently supports a finding that a POSITA would have known of FEC, CRC, ARQ, and hybrid ARQ protocols, Petitioner has not shown that the specification of the ’561 patent discloses a sufficient algorithm, whether “as a mathematical formula, in prose, or as a flow chart, or any other manner that provides sufficient structure” for the “means for detecting,” including an algorithm for performing any one or more of these protocols. Noah, 675 F.3d at 1312. The ’561 patent discloses “means (224) for detecting a need for retransmission of the received coded data block,” “CCU [Channel Coding Unit] [that] is responsible for channel coding, including forward error coding FEC” as well as detecting the “[t]he need for retransmission . . . by an error errors occurring on the channel with sufficient certainty.” Ex. 1001, code (57), 2:25, 6:64–65, 7:54–59; see id. at Fig. 5, Step 508, 10:41–44. Petitioner has not shown that the ’561 patent presents an algorithm for how the error detection code detects an error, nor explained the circumstances under which the error correcting code cannot correct errors and what constitutes “sufficient certainty.” Id. at 7:54–59. Although the ’561 patent discloses examples of incremental redundancy protocols such as “hybrid FEC/ARQ (Forward Error Correction/Automatic Repeat Request), which uses error correction coding in order to decrease the number of retransmissions,” it does not present an algorithm for implementing the same. Id. at 2:33–37. For the foregoing reasons and based on the entirety of the record developed during trial, we conclude that Petitioner fails to identify sufficient algorithmic structure corresponding to the “means for detecting” recited in independent claims 5 and 10.” slip op. at 15

“The principal difficulty with Patent Owner’s arguments is that they improperly conflate transferring desktop information with the claim’s 4 The ’288 patent instead uses the uncommon acronym “PAUNTSC,” presumably a result of incorrectly printing “L/” as “U.” recitation of “capturing” desktop information. Indeed, Dr. Bhattacharjee concedes that “the desktop information as described in the ’288 patent is transferred in digital form,” even as he maintains his opinion that desktop information is not limited to digital capture by the ’288 patent. Ex. 1020 ¶ 11. There is thus no dispute among the expert witnesses, nor the parties, that the ’288 patent describes the digital transfer of desktop information. As Dr. Bhattacharjee explains, this is a consequence of the fact that “the [’288] patent describes and claims transferring desktop information only after it is encoded.” Ex. 1020 ¶ 12. Because such encoding occurs only after the desktop information is captured, “the captured desktop information could either be digital or analog.” Id. The aspects of the intrinsic record that Patent Owner identifies as supporting its proposed construction are, in fact, consistent with this distinction between capture and transfer. For example, the “advantage of the invention” identified by Patent Owner is specifically described by the ’288 patent as raising clarity on the video communication terminal when “[d]esktop information of a PC is transferred directly in a digital coded bit stream mode without converting digital signal to analog signal.” See Ex. 1001, 2:35–39 (emphasis added). This is, moreover, consistent with the portion of the prosecution history Patent Owner identifies and which also makes clear that “the desktop information of a PC is transferred in a digital coded bit stream.” Ex. 1002, 159 (emphasis added). Petitioner’s expert, Dr. Bhattacharjee “agree[s] the desktop information as described in the ’288 patent is transferred in digital form,” even though it is not captured in digital form.

“skill in the art] would be motivated to combine even when bandwidth is shared”: (1) “the shared nature of the bandwidth only highlights that reduced bandwidth usage for desktop information provides the capability of a higher quality signal for the live stream without any extra costs in components or processing”; (2) because Kenoyer ’423 “does not disclose using a dedicated or fixed amount of bandwidth . . . , any reduction in bandwidth would reduce overall usage”; and (3) “even in a dedicated environment, Kenoyer ’423’s reduced bandwidth needs for desktop information would reduce the amount of dedicated bandwidth that is required, potentially saving costs or power.” Reply 12 (citing Ex. 1020 ¶¶ 31–32). These reasons are directly responsive to arguments raised by Patent Owner in its Response and are therefore properly considered. See 37 C.F.R. § 42.23(b). We also find such reasons, which are supported by additional testimony by Dr. Bhattacharjee, adequately explain how Patent Owner’s distinction is accommodated within Petitioner’s expressed rationale of “minimizing bandwidth usage.” See Ex. 1020 ¶¶ 31–32. Second, Patent Owner contends that, if “Kenoyer ’423 were interpreted as teaching reducing bandwidth, it does so in a different manner than in Becker.” PO Resp. 37. Specifically, “Becker addresses bandwidth reduction by using signal compression techniques,” Patent Owner says, while “Kenoyer ’423 prevents the increase in bandwidth . . . by dynamically sharing bandwidth when both a live view of the presenter and the presenter’s computer screen are being shared.” Id. Dr. Bhattacharjee disputes this distinction by observing that Kenoyer ’423’s technique still “reduces the number of bits required to convey the same video information,” and is thereby broadly encompassed as a form of “signal compression.” Ex. 1020 ¶ 33. Dr. Rosing does not specifically disagree with Dr. Bhattacharjee’s characterization. See generally Ex. 2022 ¶ 99. Regardless, both Becker and Kenoyer ’423 support Petitioner’s rationale of “minimizing bandwidth usage.” Patent Owner inadequately explains how a distinction in the precise manner that might be accomplished by the two references diminishes the support provided by the rational underpinnings identified by Petitioner. See PO Resp. 37 (Patent Owner making the conclusory statement that “[a]s such, Petitioner fails to provide a valid motivation for combining Becker and Kenoyer ’423”).” slip op. at 26

We give credit to Dr. Nielson’s testimony in this regard that both Dubrovsky and Campbell recognize that executables were a frequent source of malware but that Dubrovsky does not provide specific details regarding how a file would be determined to be executable. Ex. 1005 ¶¶ 404–405.

Ex. 1005 ¶¶ 404–406. We agree with Petitioner that Campbell teaches that a file’s header can be used to determine that the file is an executable.
