    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “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. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art). We nevertheless note that we would reach the same ultimate conclusion that claims 1, 3, 5, 9, 12, 13, and 15 (but not claims 20 and 21) have been shown to be unpatentable by a preponderance of the evidence were we to adopt Patent Owner’s proposal.

      “We need not resolve this dispute because we reach the same ultimate conclusion that Petitioner shows, by a preponderance of the evidence, that claims 1, 3, 5, 9, 12, 13, and 15 are unpatentable, but not that claims 20 and 21 are unpatentable, even if we apply Patent Owner’s proposed construction that the preambles are limiting and the first and second data files must be different. See Reply 15 (Petitioner asserting that “there is no need to construe the preambles as the prior art meets them even if construed”); Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). For purposes of this Decision, we accordingly treat the preambles of independent claims 1 and 9 as limiting, and with the recited “first data file” and “second data file” as distinct data files.4” slip op. at 14

    • 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. See Reply 3. We accordingly adopt the definitional construction provided by the” slip op. at 16

    • Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalDisclaimer not foundDecided for petitioner

      “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. Inst. of Tech. v. Shire Pharms., Inc., 839 F.3d 1111, 1119 (Fed. Cir. 2016). And “[s]tatements by the patent owner are not considered in a vacuum; rather, the skilled artisan would look at the record as a whole in assessing claim scope.” Galderma Lab’s v. Amneal Pharma, 806 F. App’x 1007, 1010 (Fed. Cir. 2022) (citing Wang Labs., Inc. v. Toshiba Corp., 993 F.2d 858, 867 (Fed. Cir. 1993) (“The prosecution history must be examined as a whole in determining whether estoppel applies.”)). We have reviewed the prosecution history, which we summarize supra § I.A.3., and we have particularly reviewed those portions highlighted by Patent Owner. See PO Resp. 32–40. We reach the same conclusion as the district court in the Starz litigation that the standard for attachment of prosecution disclaimer is not met. See Ex. 1018, 109:15–22 (district court stating at Markman hearing, “I’ve also carefully reviewed the portions of the prosecution history relied on by VideoLabs, including the patentee’s arguments regarding the Shin and Rosenau references, and I’m up [sic: not6] persuaded there was a clear and unmistakable disclaimer of all assignment rules that perform assignments by using exact timing information”). slip op. at 20

      “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. We also find that the preponderance of the evidence supports Petitioner’s showing regarding the motivation to combine the references.” slip op. at 23

In addition, Petitioner shows that these control signals were well-known in the art and would have been known to one of ordinary skill in the art at the time of the invention, supporting its showing with additional testimony from its declarant.

We conclude Petitioner’s evidence regarding the showing in Hart-787 is sufficient with respect to this point. Hart-787 describes altering a signal sent to the speaker to attenuate the audio from that speaker. Ex. 1004, 1:67– 2:1. Petitioner’s declarant testifies that using transmitted control signals to do this would have been known to one of ordinary skill. Ex. 1003 ¶¶ 44–45, 82, 118. We consider Petitioner’s evidence regarding what one of ordinary skill in the art would have understood from Hart-787’s disclosure to be sufficient for the showing regarding the “causing one or more commands to be automatically issued to the controllable appliance to thereby cause” that appliance to transition to a lower volume level, as required in limitation 1.e.

These “limited opportunities” include “in a reply to the patent owner response,” provided that the additional evidence is “responsive to the prior briefing” and provided that the additional evidence does not require “completely reopen[ing] the record, by, for example, changing theories after filing a petition.” Id. at 14–15.

Patent Owner challenges RadioShack’s status as a printed publication in its Response, just as Hulu contemplates. Hulu at 15; PO Resp. 28–41. And Petitioner submits additional evidence that replies to that challenge without changing its theory that RadioShack qualifies as a printed publication by virtue of its accessibility on the RemoteCentral.com web site and in light of date indicia on RadioShack itself.8 See Hulu at 15–16; Reply 7–13. 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.

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

Dr. Davis provides credible testimony that because, in Moshchuk, the file that is provided in response to the request is an HTML root page, the HTTP header for the file would have merely indicated that the returned file is an HTML file, which is not a file type associated with being an executable, and would not have indicated whether the file contains active or passive content.

      “After this proceeding was remanded by the Federal Circuit, we invited the parties to address a proposed procedure that would include additional briefing regarding the impact of the prior holdings that claims 1–3, 5, and 10–20 are unpatentable, and the parties filed their respective proposals. Papers 78–80. In its proposal, Petitioner suggested that Patent Owner “has waived the right to address the patentability of claims 4, 8, and 9” because “Patent Owner never separately argued for the patentability of these claims.” Paper 79, 1; see MaxLinear, 880 F.3d at 1378 n.4 (“On remand, the Board may consider whether CRESPE has waived arguments concerning these claims.”). But those claims were not challenged in the earlier proceedings that held claims 1–3, 5, and 10–20 unpatentable. Rather, those claims were only challenged in this proceeding with respect to art that was not at issue in the earlier proceedings. In advancing its contention, Petitioner effectively makes the untenable argument that Patent Owner must provide separate reasons for the patentability of claims 4, 8, and 9, even when we determine that its own case-in-chief for those claims is insufficient. In addition, Petitioner’s proposal requests briefing on the issues of “whether claims 6, 7 and 20 materially alter the [unpatentability] analysis on which the prior [unpatentability] determinations rested.” Id. We have considered, and deny, that request. The Federal Circuit’s remand order noted that the fact that “MaxLinear was not a party to the other IPRs is . . . irrelevant since Cresta, the predecessor in interest to CRESPE, was party to the original determination.” MaxLinear, 880 F.3d at 1377. But the Federal Circuit’s order does not state or suggest that the fact that different prior art was considered in the earlier proceedings is similarly irrelevant. Indeed, we agree with Patent Owner that “[t]he Federal Circuit has not ordered the Board and the parties to start over from scratch, and certainly not with new prior art.” Paper 80, 3; see Ariosa Diagnostics v. Verinata Health, Inc., 805 F.3d 1359, 1367 (Fed. Cir. 2015) (“The Board may control its own proceedings, consistent with its governing statutes, regulations, and practice.”). Patent Owner is correct that “[a]llowing new prior art to be considered on remand after the Final Decision on the merits would essentially be starting a new IPR proceeding.” Paper 80, 9. As Patent Owner asserts, “[t]he parties and the Board would have to argue and consider new grounds, new expert testimony would have to be taken and presented, and a new Final Decision would have to be rendered.” Id. The Federal Circuit’s instruction is limited: “We remand this case to the Board so that it may consider the patentability of the surviving disputed dependent claims 4, 6-9, and 21.” MaxLinear, 880 F.3d at 1378. We have complied with this instruction in two ways: first, by applying the Federal Circuit’s instruction regarding the collateral-estoppel impact on challenged claims 1–3, 5, and 10–20; and, second, by clarifying that Petitioner’s argument regarding the combination of Van De Plassche and Ishikawa compels a conclusion that Petitioner’s showing is insufficient with respect to claims 4, 6–9, and 21, independent of any conclusion previously reached with respect to independent claims 1 and 17. While the Federal Circuit includes language in its remand order that might be construed as suggesting applying different prior art in the latter analysis, 880 F.3d at 1377, the scope of this proceeding is limited by the prior art and the arguments in the Petition here.

      “Experience is but one of several factors that may be considered when determining the level of ordinary skill in the art. See, e.g., In re GPAC, 57 F.3d 1573, 1579 (Fed. Cir. 1995) (identifying factors as 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 a given case, every factor may not be present, and one or more factors may predominate.” Id. Patent Owner’s distinction relates to a portion of one factor (education) in a determination that involves several factors. The significance of the level of ordinary skill in the art is the role it plays in an obviousness analysis. See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966); Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Nu-Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991) (“The importance of resolving the level of ordinary skill in the art lies in the necessity of maintaining objectivity in the obviousness inquiry”). Patent Owner does not explain persuasively how the alleged omission by Petitioner impacts the obviousness analysis.

      “Importantly, we find that Patent Owner did not exhaust avenues available to it in attempting to secure answers to its questions from Dr. Hashemi. The line of questioning involving Exhibit 2008 occurred late in the day, “well after the close of business on the east coast,” and an attempt by the parties to telephone the Board during the deposition was unsuccessful. See Opp. 3; Ex. 2006, 154:24–155:4. The parties discussed contacting the Board the following day, and continuing the deposition the day after that, when Petitioner would make Dr. Hashemi available for further cross-examination after receiving guidance from the Board. Ex. 2006, 155:5–157:13. Rather than proceed in this fashion, Patent Owner decided to abandon the line of questioning and passed the witness for redirect: “I think after we talked about it a bit, I think we will withdraw our questions on this document and just move on to redirect.” Id. at 157: 22–25 (emphasis added). Dr. Hashemi could have answered the questions and sought a protective order that would insulate his answers from the public record, providing the Board with the information needed to perform a focused evaluation of the credibility and reliability of specific statements in his testimony. But a significant measure of responsibility for whether Dr. Hashemi’s testimony is tainted with bias lies with Patent Owner for declining to pursue the issue to a point of greater clarification. Indeed, we are limited in how strongly we can fault Petitioner for failing to submit a clarifying declaration from Dr. Hashemi, in light of Patent Owner’s decision to “withdraw” the questions at issue. Because the evidence is insufficiently developed, we are similarly limited in the degree to which we can draw adverse inferences from Dr. Hashemi’s refusal to answer questions, and unable to conclude, by a preponderance of the evidence, that Dr. Hashemi’s testimony is tainted by an undisclosed bias.

In addition, the fact that certain figures of Chou might depict a junction box external to a can light does not mean that junction boxes are excluded from the universe of “recessed housings” contemplated in the quotation above. In addition, Patent Owner contends Petitioner has provided no reason or motivation to combine Wegner with Chou. PO Resp. 10–11. Patent Owner also contends an ordinarily skilled artisan would not have combined Wegner with Chou because Wegner pertains to a light with a tall reflector, which must be installed in a can light fixture (and not a junction box). Id. at 11–12 (citing Ex. 2001 ¶¶ 74–75, 133–137). Yet Petitioner only cites Wegner for its teaching of removing an Edison base from an LED light fixture to facilitate direct wiring, and not for anything to do with reflectors. Pet. 24 (citing Ex. 1002 ¶ 53; Ex. 1016, 11:3–32). As such, Patent Owner’s arguments regarding Wegner’s light reflectors amounts to a bodily incorporation argument, which is not the test for obviousness. See In re Keller, 642 F.2d 413, 425 (CCPA 1981) (“The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.”). We are persuaded that, based on Wegner, an ordinarily skilled artisan would have known to remove the Edison base of Chou’s fixture regardless of the type of reflector and housing used in Wegner’s fixture. See Ex. 1002 ¶ 53. Regarding motivation, Petitioner posits a market-based rationale, namely, that an ordinarily skilled artisan would have been motivated to make a version of Chou’s luminaire to fit nominally sized junction boxes to serve the new construction market. Pet. 25 (citing Ex. 1002 ¶ 54). Dr. Coleman testifies that the Edison base would have been removed to make Chou’s luminaire work in a junction box. Ex. 1002 ¶ 53. We are persuaded that an ordinarily skilled artisan wanting to modify Chou for use in junction boxes would have known to make this modification.” slip op. at 19

    Claims 5 and 6 are unpatentable as obvious over Mason, Shuey, and Cunningham; Petitioner did not show claim 8 unpatentable on that ground.

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed petitioner constructionDecided for petitioner

      “construction against the prior art than it does to construction of the term itself. Patent Owner’s proposed construction, like Petitioner’s, does not, on its face, exclude RF protocol conversion. In this respect, we agree with Petitioner that Patent Owner is improperly attempting to read in additional limitations that go beyond claim 5’s broad recitation of a “transmitter . . . configured to encode the electrical signal.” See Paper 45, 3. As Petitioner further observes, the Specification of the ’661 patent refers interchangeably to data controller 324 (shown in Figures 3A–3E, not reproduced here) as “data formatter 324” (emphasis added), which “operates to form concise data packets.” Id.; Ex. 1001, col. 8, ll. 49–51. Petitioner’s proposed construction is thus consistent with the Specification. Patent Owner agrees that data controller 324 “encodes a physical condition into a function code,” but emphasizes that it does so “before getting converted by the RF transmitter.” Paper 44, 3. The distinction Patent Owner relies on to exclude RF protocol conversion from its proposed construction would improperly narrow the scope of the claim by implicitly adding a limitation that has no express basis in the claim. In re Prater, 415 F.2d 1393, 1404–05 (CCPA 1969) (“Nevertheless, ‘reading a claim in the light of the specification,’ to thereby interpret limitations explicitly recited in the claim, is a quite different thing from ‘reading limitations of the specification into a claim,’ to thereby narrow the scope of the claim by implicitly adding disclosed limitations which have no express basis in the claim.”). Having thus considered the parties’ positions, we adopt Petitioner’s proposed construction of “encoded electrical signal” as “coded information representing the electrical signal generated by the sensor.” We address application of this construction to the prior art in the analysis below.” slip op. at 12

    • Skill levelSkill level patent owner adoptedDecided for patent owner

      “Patent Owner does not advocate for a specific level of skill in its Response, but its expert, Kevin C. Almeroth, Ph.D., articulates a level of skill similar to Petitioner’s proposal. Ex. 2009 ¶ 75. Specifically, Dr. Almeroth opines that a person of ordinary skill “would have the equivalent of a four-year degree from an accredited institution (usually denoted as a B.S. degree) in computer science, computer engineering or the equivalent and experience with, or exposure to, computer networks and routing.” Id. In addition, according to Dr. Almeroth, a person of ordinary skill “would also have approximately two years of professional experience with computer networking, routing, and wireless networks. Id. And “[a]dditional graduate education could substitute for professional experience, while significant experience in the field might substitute for formal education.” Id. Given the similarity of articulations by the respective experts, and because our Decision does not depend on nuanced distinctions of the level of skill in the art, we adopt Dr. Almeroth’s more detailed articulation, but include electrical engineering as an additional alternative educational background, as indicated by Mr. Kinney.” slip op. at 15

      “We thus agree with Patent Owner that the rationale articulated by Petitioner is conclusory, and insufficiently supported. PO Resp. 30–31. On the record before us, it is more reasonable to construe “the transceiver identification information” as referring to something other than the identification information for the at least one wireless transmitter. For example, Patent Owner contends that “[o]ne skilled in the art, reading the plain text of claims 5 and 8, would easily recognize that the ‘transceiver’ referred to in claim 8 is the transmitter in claim 5 that is configured to both send and receive signals.” Id. at 33. Patent Owner provides support for this reading both by identifying disclosure in the Specification of the ’661 patent consistent with its position, and through testimony by its expert, Dr. Almeroth. Id. at 33–36 (citing Ex. 1001, Figs. 2, 3C, 3D, col. 6, ll. 3–8, col. 9, ll. 53–56, col. 10, ll. 32–34; Ex. 2009 ¶¶ 125–132). For example, Dr. Almeroth testifies that Mason’s AMR server “at most would need only some meter identification number and a meter reading.” Ex. 2009 ¶ 134. We credit this testimony, as well as Dr. Almeroth’s assertion that “[t]ransceiver identification information is extraneous for the needs of the AMR server in Cunningham and Mason.” Id. Ultimately, we need not resolve the construction issues, and the issue of whether claim 8 is indefinite is not before us. 35 U.S.C. § 311(b) (limiting inter partes review to “a ground that could be raised under section 102 or 103”). It is sufficient for us to determine whether Petitioner has put forth sufficient evidence to meet its burden of establishing that claim 8 would have been obvious over the combination of Mason, Shuey, and Cunningham. In light of the foregoing considerations, we conclude that Petitioner has not.” slip op. at 34

      “c. “one or more additional wireless transmitters” Third, Petitioner combines the teachings of Shuey with those of Mason in addressing claim 5’s recitation of “one or more additional wireless transmitters.” Id. at 62–63. The claim requires that each such additional wireless transmitter is “electrically interfaced with a sensor and configured to receive the RF signal and retransmit the RF signal,” i.e., to act as a repeater. Ex. 1001, col. 19, ll. 22–24. As discussed above, Mason discloses that meter 12D is considered “inaccessible” with respect to node 18, and that another meter within the network may act as a repeater so that the inaccessible meter may still be contacted. Id. at col. 6, ll. 27–35. Petitioner cites Shuey for details regarding the information included in retransmission by meters acting as repeaters, and provides sufficient reason to effect the combination in light of Mason’s explicit reference to Shuey: “A POSITA would have been motivated to incorporate into Mason’s system Shuey’s teaching of a repeater that retransmits all of the claimed information, because Mason explicitly notes that Shuey’s system is a system for which Mason’s invention is particularly suited.” Pet. 58–59 (citing Ex. 1007, col. 6, ll. 35–38; Ex. 1002 ¶¶ 110–112). Petitioner’s reasoning is thus supported by sufficient rational underpinning. KSR, 550 U.S. at 418.” slip op. at 24
