      “real party in interest. Prelim. Resp. 1–2, 32–34. In the Institution Decision, we stated: To the extent Patent Owner seeks to pursue its argument that Linq3 is a real party of interest to Petitioner, even though no time bar under 35 U.S.C. § 315(b) has been asserted, Patent Owner may raise the issue of real party in interest again in its Patent Owner Response and the parties may brief and argue the issue during trial. Inst. Dec. 11. In its Patent Owner Response, Patent Owner did not raise the issue of challenging Petitioner’s identified real party in interest. See generally PO Resp. Thus, we need not address this issue further because we find that Patent Owner has waived any challenge to Petitioner’s identification of the real parties in interest in this proceeding. See Paper 12 (Scheduling Order), 9 (“Patent Owner is cautioned that any arguments not raised in the response may be deemed waived.”).” slip op. at 5

      “B. Level of Ordinary Skill in the Art Petitioner proposes that the level of ordinary skill in the art is an artisan with a working knowledge of POS activation systems and lottery systems that was gained through a mixture of training and work experience in the relevant field such as (i) having a Bachelor’s degree in computer science, computer communications, electrical engineering, or equivalent degree, coupled with at least three years of work experience; (ii) having a Master’s degree in computer science, computer communications, or electrical engineering, but having less work experience; or (iii) having no formal degree, but having experience in the relevant field of at least six years of work experience. Pet. 2–3 (citing Ex. 1003 ¶ 13).5 Patent Owner states that, “[f]or the purpose of this proceeding, Patent Owner adopts the Petition’s proposed definition of the level of ordinary skill in the art.” PO Resp. 19. 5 Petitioner proposes the same level of ordinary skill in the art that the Board adopted in PGR2020-00084. Pet. 2–3 (citing Ex. 1008, 11). We find that the parties’ agreed-upon level of ordinary skill in the art is consistent with the level of ordinary skill in the art reflected by the ’135 patent and the prior art of record. See Inst. Dec. 14; see Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).

      “Following the block quote from Yacenda, the applicant then stated, “[b]ased on the foregoing, Yacenda’s system is directly opposite of the instant claims, as the instant claims require a ‘pre-printed lottery ticket’ which has no lottery numbers associated with it at the time of customer purchase.’” Ex. 1002, 76. This statement is clear and unmistakable. It (1) specifically states that “the instant claims require” and (2) then states what the claims require—a “‘pre-printed lottery ticket’ which has no lottery numbers associated with it at the time of customer purchase.” We fail to see how the applicant could have been more clear in stating a requirement of the Challenged Claims. And, by doing so, the applicant narrowed the scope of what would otherwise be encompassed in the meaning of “pre-printed lottery ticket” and therefore what would otherwise be encompassed in the scope of the Challenged Claims—a lottery ticket which has lottery numbers associated with it at the time of customer purchase.” slip op. at 27

    • Expert testimonyPetitioner expert discountedDecided for patent owner

      “We do not find Mr. Hutton’s testimony particularly helpful. First, we have addressed the points raised by his testimony in our discussion above because they are largely the same as the arguments raised in Petitioner’s Reply. Second, we find his testimony entitled to very little weight because he applies an incorrect understanding of the caselaw, which mirrors Petitioner’s incorrect and arguably misleading quotations of the Federal Circuit’s decision in Quest. In particular, in paragraph 5, Mr. Hutton states the following as his understanding of the law as it applies to prosecution disclaimer: “I also understand that in order to disclaim embodiments within the specification, the statements should have some indication that the applicant intended to surrender embodiments from the specification.” Ex. 1038 ¶ 5 (emphasis added). This then leads Mr. Hutton to state: “[t]hus, in my opinion, a [person of ordinary skill in the art] would not view applicant’s statements as a disclaimer, because the applicant never stated that they intended to surrender multiple embodiments described in the specification.” Id. ¶ 13 (emphasis added). As we explained above in responding to a similar argument by Petitioner, the caselaw does not require an applicant to expressly state whether a disclaimer excludes particular embodiments of the subject specification when disclaiming claim scope during prosecution. See Quest, 924 F.3d at 1229. And, as noted above, counsel for Petitioner agreed that such a statement explicitly disclaiming particular embodiments is not required. Tr. 12:18–13:17. Third, although we have considered Mr. Hutton’s testimony, we find it “less significant than the intrinsic record in determining the legally operative meaning of” “pre-printed lottery ticket.” Phillips, 415 F.3d at 1317. In particular, we are cognizant of the Federal Circuit’s guidance that we “should discount any expert testimony that is clearly at odds with the claim construction mandated by . . . the prosecution history.” Id. at 1318 (internal quotation omitted). In this instance, for the reasons explained above, we find that Mr. Hutton’s testimony is clearly at odds with the applicant’s arguments during prosecution and that his testimony is based on a misunderstanding of what is required by the governing caselaw for prosecution history disclaimer.” slip op. at 43

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “We determine Patent Owner’s reading of the claim limitation is the better one. The limitation begins with the verb “locating,” and it therefore makes sense that the clause would recite what is located (i.e., encryption information) and where it is located (i.e., within the requested portions of the selected stream of protected video). In other words, it is reasonable that the second and third clauses of the limitation both modify the first clause (for example, as could perhaps be expressed through the use of commas as “locating encryption information, that identifies encrypted portions of frames of video, within the requested portions of the selected stream of protected video”).10 On the other hand, Petitioner’s reading of the limitation, 10 In general, we recognize that the use of commas to set off phrases in claim drafting is not consistent. We included commas above to illustrate Patent Owner’s understanding of the claim limitation. allowing only the second clause to modify the first, while not unreasonable, makes less sense. That is, the encrypted information identifies the encrypted portions of frames, which in turn are within the requested portions of the selected stream of protected video. Reading the claim in its entirety, the encrypted portions of frames would be understood to be located within the requested portions of the stream; it does not seem necessary for the claim to expressly recite that aspect. For example, the very next limitation— limitation [m] of claim 1—refers to “each encrypted portion of the frames of video” but does not expressly recite “within the requested portions of the selected stream.” Ex. 1001, 27:58–60. Thus, when limitation [l] recites “within the requested portions of the selected stream,” it seems more likely that the clause refers to where that encrypted information is located rather than simply to indicate the obvious location of the encrypted portion of the frames of video. We therefore view Patent Owner’s reading of the claim language as the better one.” slip op. at 13

      “I am persuaded that the Petition demonstrates that one of ordinary skill in the art would have had a motivation to combine Chen, Lindahl, and Hurst, as asserted by Petitioner. As the Federal Circuit found, the Petition pointed to and relied upon the portions in Chen describing pre-Chen art, without scalability or FEC features that were part of what Chen describes as aspects of its own inventive system. Netflix, slip op. at 9–10 (citing Pet. 17– 19, 69–70).

I determine that Chen-924 provides support for the rationale provided in the Petition, and that one of ordinary skill in the art would have been motivated to combine Chen and Lindahl in view of the disclosure of Chen-924. As discussed above, the Petition does not rely solely on privacy concerns and improvements to efficiency as its motivation to combine the references.

      “I agree with Petitioner that Patent Owner’s Remand Brief, specifically pages 1–7, attempt to address aspects of claim 1 for the first time on remand. I also agree that Patent Owner’s arguments attempt to recharacterize limitations [j] and [k] to raise issues that Patent Owner did not raise previously, in contravention of our Order that issues raised needed support from “where those issues were raised in previous briefings by the parties.” Paper 56, 2. I have addressed whether scalability and FEC are integral to how Chen operates above, as well as whether the Petition relies on those aspects, supra. The questions about how Chen operates and what portions of Chen are asserted in the ground of unpatentability were previously raised, but now are being considered or reconsidered, based on the Federal Circuit’s decision. In Patent Owner’s Remand Brief, pages 1–7, the citations to argument previously raised do not support the arguments now presented by Patent Owner on remand. As such, I determine Patent Owner’s new arguments fall outside the scope of remand, and I dismiss these arguments seeking to distinguish limitations [j] and [k] from the cited prior art combination.24” slip op. at 62

    • ExcludeMotion to exclude, grantedMixed

      “7 Patent Owner’s Brief on Remand recognizes that there are two arguments Patent Owner raised in its Patent Owner Response that were not addressed in the Final Written Decision. See PO Remand Br. 1 (citing PO Resp. 24–37 (the construction of “locating encrypted information . . . within requested portions”), 38–58 (referring to Patent Owner’s “common keys” argument)). 8 The Final Decision also addressed Petitioner’s Motion to Exclude (Paper 42). See Final Dec. 28–37 (granting-in-part, denying-in-part, and dismissing-in-part Petitioner’s Motion). Our determinations on that Motion were part of Petitioner’s appeal to the Federal Circuit. See Paper 52. Because the Federal Circuit did not address this aspect of the Final Written Decision and the Federal Circuit’s decision does not impact our previous rulings on the Motion, we maintain those rulings here. Additionally, on remand, Petitioner requested authorization to file a motion for sanctions, which we held in abeyance until the parties’ briefing on remand was complete. See Ex. 3003, 1. Petitioner requests sanctions because of the impropriety of Patent Owner’s remand brief, including new claim construction arguments for limitations [1j] and [1k], and prejudice to Petitioner. Id. at 3, 5. Although we reserved further consideration of Petitioner’s request, we expanded both the time and pages allowed for Petitioner’s responsive brief, and also allowed Petitioner to address any related issues in its responsive brief. Id. at 1. Having considered the parties’ briefing on remand, and given that we do not reach the claim construction arguments that Petitioner objected to in its request for authorization to file a motion for sanctions, we deny Petitioner’s request.” slip op. at 5

      “for a LUT having the recited deltas except for Dr. Blumenthal’s analysis. Although Wright generally teaches compensating for mismatches, Dr. Blumenthal’s analysis fills in limitations 13.8 and 13.9––Petitioner does not set forth a sufficiently supported reason for using the specific values recited in limitations 13.8 and 13.9. At best, Petitioner presents an “obvious to try rationale”: In addition to the reasons mentioned above, a POSITA would have found it obvious to try a mapping scheme in which entries in the look-up table as taught by Taraschuk are selected such that successively decreasing inputs correspond to digital output entries with either decreasing, increasing, or similar deltas between their values. . . . Doing so would have involved choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success. In that regard, the deltas between values of the corresponding digital outputs can either increase, decrease, or stay the same. Accordingly, there are only three possible relationships between deltas of successive digital outputs. With so few possibilities, a POSITA would have found it obvious to try each of them. Pet. 59 (citing Ex. 1003 ¶ 265). The analysis for 13.8 is incorporated by reference in 13.9. See Pet. 60. Although there are three possible relationships between two, consecutive deltas, there are many possible sequences of deltas––Petitioner does not sufficiently show a finite number of solutions in its challenge.” slip op. at 30

      “We agree with Patent Owner’s argument that the portions of Taraschuk in column 7, lines 61–67 and column 8, lines 13–15 cited by Petitioner in its challenge to claim 13 teach “an end-to-end approach” “because that calculation involves predistortion of the input M-bit word by subtracting a digitized analog sample of the ultimate output,” and as such, teach “[a]n approach that necessarily does one combined correction for all of the nonlinearities that occur in-between those ends—whether bit mismatches in the digital logic or non-linearities in the Mach-Zehnder modulator.” PO Sur-reply 18 (citing PO Resp. 30–36; Ex. 2018 ¶¶ 48, 49, 85–87, 89, 103; Ex. 1006, 7:34–39, 7:61–67). We further agree with Patent Owner’s assertion that [Patent Owner] and Prof. Dallesasse are not suggesting that Dr. Blumenthal should model the logic-level mismatches. But rather pointing out that calculating an idealized sinusoidal response in isolation is not obvious (or flowing naturally) from a reference that can only deal with compensating the combined response of the modulator and digital logic mismatches together—via real-time pre-distortion fed back from the ultimate output and subtracted from the input. Dallesasse testifies that Dr. Blumenthal starts with the premise that all that is required is deriving a complementary function to the sinusoidal response. . . . But this ignores that the disclosure of Taraschuk describes compensating “the sinusoidal response of the modulator” and “logic level mismatches through the D/A converter” together. . . . Dr. Blumenthal’s complementary sinusoidal correction curve won’t do that. The combined non-linearity from the multiple sources likely won’t simply be evenly sinusoidal. Taraschuk does not disclose, or in my opinion render obvious, any pre-calculation solution. (Taraschuk mentions a real-time analog feedback loop to pre-distort, which would not involve pre-calculation.) And it certainly does not suggest one that could deal with the combined and likely complex non-linearities described.” slip op. at 28

      “Inst. Dec. 25–26 (citing Ex. 1006, 8:2, 8:8, 6:61–65; Ex. 1003 ¶ 147; Prelim. Resp. 46). Based on our review of the complete record developed during trial, we are persuaded to modify our preliminary determinations. For the reasons discussed below, we are persuaded that the scope of claim 1 does not encompass linear compensation methods effected by analog pre-distortion because the ’872 patent specification distinguishes analog pre-distortion (see Ex. 1001, 1:55–2:34) and the prosecution history specifically distinguishes analog pre-distortion from the claimed approach (see Ex. 1002, 172). We find persuasive Dr. Dallesasse’s testimony that “a person of ordinary skill in the art reading the [’872] patent would understand that th[e] [claimed] approach differs from pre-distortion based on real-time measured analog modulator output.” Ex. 2018 ¶ 33 (citing-in-part Ex. 1001, 2:3–7 (’872 patent disclosing common, prior art solutions such as “an analog predistortion circuit to feed the modulator”)); see also Ex. 1001, (the ’872 patent describing the need for a “digital to analog converter” that would “improve[] linearity of response without sacrificing efficiency or dynamic range” as in the common, prior art solutions). Dr. Dallesasse explains how “the prosecution history of the ’872 patent [illustrates] that when [Patent Owner] changed ‘correct for non-linearities’ to the more specific language ‘determined based on a pattern for actuating drive voltages that alters the linearity of an optical response of the modulator,’” “the Examiner then allowed the claims over a rejection based on Roberts, which “suggests that there are ways to ‘correct for non-linearities’ that do not meet the amended Ex. 2009, 2; Ex. 2003). During prosecution, Patent Owner argued: Roberts does not disclose a “digital-to-digital mapping,” where, “for a given plurality of N digital input data bits, the mapping to the corresponding M digital output data bits is determined based on a pattern for actuating drive voltages that alters the linearity of an optical response of the modulator,” as recited in amended claim 1. Instead, the linear compensation in Roberts is performed pursuant to a compensation function c(t) when the Vx(n) multi-bit sample streams are generated. Importantly, this linear compensation in Roberts occurs before the mapping of Vx(n) to Sx(n). As a result, the mapping between Vx(n) to Sx(n) in Roberts, such as the mapping shown in Table 1 of Roberts, is not a part of the linear compensation operation performed in Roberts. Ex. 1002, 172 (emphasis added). We interpret the quoted passage to exclude analog pre-distortion because we interpret the argument distinguishing Robert’s compensation as happening “before the mapping” to refer to pre-distortion techniques––in particular, those accomplished by analog compensation function, c(t). Id. Both the ’872 patent and Patent Owner’s arguments during prosecution support Dr. Dallesasse’s testimony and Patent Owner’s position that the scope of claim 1 does not encompass linear compensation methods effected by analog pre-distortion.” slip op. at 21

      “mapping is based on an analog feedback loop, by . . . quoting from the reference and leaving out the very next sentence” has merit. Sur-Reply 8 (citing Pet. Reply 23). Petitioner does not sufficiently address the cited teachings and in particular, Taraschuk’s teachings of calculating a difference between a “sampled analog output signal (S) and corresponding M-bit word” to a calculate a mapping “required to obtain the desired output analog signal level.” Ex. 1006, 7:34–39. We are persuaded Petitioner does not sufficiently rebut Patent Owner’s contention that Roberts’ and Taraschuk’s teachings of linear compensation are implemented by analog pre-distortion. Petitioner cannot ignore these teachings of Taraschuk and consider only the portions that support its challenge. See Pet. Reply 17 (citing Pet. 43–45; Ex.1006, 7:56–60) (“Patent Owner’s emphasis on Taraschuk’s digital feedback loop is also misplaced because the Petition simply relied on Taraschuk’s linearizer 44 as a discrete, known device for performing non-linear compensation of a Mach-Zehnder modulator.” (emphasis added)).

      “Second, Petitioner concludes that “a POSITA would have found it obvious to map input bits to output bits within the look-up table such that the output bits correspond to voltage values to be transmitted to electrodes of an optical modulator,” but offers no support other than Robert’s teaching that the DSP’s output is a multi-bit parallel binary signal. See id. at 51 (citing Ex. 1005, 6:40–42). That is, the sole basis for Petitioner’s conclusion that it would have been obvious to perform the claimed method is that the output is the same. Id. This is impermissible hindsight. Third, Petitioner essentially argues that a person would have found it obvious to perform the mapping because Taraschuk teaches a look-up table and non-linear compensation. Id. at 51–52. Yet the claim recites how the mapping is performed, which is left unaddressed by Petitioner. Id. That is, Petitioner has not shown where Taraschuck teaches mapping a given number look-up table, so that the output bits compensate for the non-linear effects of the optical modulator. Id. at 52. Rather, Petitioner provides a piecemeal analysis that uses the ’872 patent’s specification as a blueprint to pull together a look-up table, non-linear compensation, and a modulator to arrive at the claimed invention. See id. Thus, all three rationales for limitation 1.9 are deficient. See PO Resp. 27.” slip op. at 30

Id. at 6. Following our Preliminary Guidance, the parties submitted further arguments concerning the term “for a pharmaceutical composition.” Patent Owner argues the term requires that the claimed process provide STS that is sufficiently pure for use in a pediatric patient (see RMTA 8–11) and that the word “drug” in the ’363 patent’s definition of “pharmaceutical composition” requires that the anhydrous STS is of sufficient purity for pharmaceutical use. Reply RMTA 3. Petitioner argues that the construction set forth in our Preliminary Guidance was correct. See Sur-reply RMTA 2–3. Having considered the arguments and evidence, we do not further construe the term “for a pharmaceutical composition” in this Decision because, as discussed in our analysis of obviousness below, it is not necessary to construe the term in order to determine whether Petitioner has met its burden of demonstrating by a preponderance of the evidence that proposed substitute claims 28 and 29 are unpatentable.

      “determine the evidence relied on by Petitioner does not support Petitioner’s position that a person of ordinary skill in the art would have been motivated to combine Levenson, Sherman, Edwards, and USP. Petitioner’s contention that it would have been obvious to a person of ordinary skill in the art to combine the teachings of Levenson with Sherman is based on Dr. Rogers’s testimony that “[b]oth references disclose synthesis of sodium thiosulfate pentahydrate.” Ex. 1008 ¶ 151; see Pet. 36, 38. Dr. Rogers further testified it would have been obvious to add Edwards’s dehydrating step to the preparation of STS pentahydrate “which is obtained following the teachings of Levenson and Sherman” because “Edwards itself discloses dehydrating [STS] pentahydrate.” Id. ¶ 154. The Petition included these arguments even though they were inconsistent with Petitioner’s previous statement, during the Sherman prosecution, that Levenson taught STS heptahydrate, and therefore “does not provide any teaching with respect to [STS] pentahydrate.” Ex. 2013, 97. This prior inconsistent statement undercuts Petitioner’s rationale for combining Levenson, Sherman, and Edwards in this proceeding. Moreover, Petitioner’s rationale for combining the references in this proceeding is inconsistent with its statements about Levenson during the Sherman prosecution. Recognizing this inconsistency, Petitioner now takes the position that the Petition and Dr. Rogers’s testimony were incorrect. Paper 32; see Tr. 21:14–22:7, 59:1–2 (reemphasizing that “Petitioner maintains the statements that it made in the Sherman prosecution regarding Levenson”). Petitioner attempts to rationalize the inconsistency between its statements in the Sherman prosecution (including that “Levenson does not provide any teaching with respect to [STS] pentahydrate”) and its position in this proceeding by arguing that Dr. Rogers relies on Levenson as teaching surface activation “regardless of any particular hydrates Levenson discloses.” Tr. 22:8–9. That argument is not persuasive, because Dr. Rogers’s declaration clearly states the primary reason for his opinion that it would have been obvious to a person of ordinary skill in the art to combine the teachings of Levenson with Sherman: “[b]oth references disclose synthesis of sodium thiosulfate pentahydrate.” Ex. 1008 ¶ 151. Contrary to Petitioner’s argument, Dr. Roger’s reliance on the surface activation teachings of Levenson is because he believes that both references pertain to STS pentahydrate; the surface activation teachings are not stated as an independent reason to combine the references. Id. Petitioner provides no further explanation of how a person of ordinary skill in the art would have been motivated to combine Levenson’s teachings regarding manufacture of STS heptahydrate with Sherman’s and Edwards’s teachings regarding STS pentahydrate, or how a person of ordinary skill would have regarded the difference between STS hydrates. Dr. Rogers’s acknowledgement of stability differences among STS hydrates highlights the insufficiency of Petitioner’s showing in this regard. See Ex. 2005, 35, 39.

In the Petition, Petitioner argued that “header information” was the same in each message (received and response). Pet. 32 (citations omitted), 36–37. Petitioner relies on Tables 58 and 63, which show “Header.” Id. at 32–33, 37. Petitioner also relies on paragraphs 102 and 118 of Mr. Andrews’s Declaration. Neither the Petition nor Mr. Andrews’s Declaration, however, provide any sufficient basis to find that even a portion of the header or header information is copied from the received message to the response message. Mr. Andrews states his opinion as though it were fact without providing the underlying factual support for his opinion. See Ex. 1003 ¶¶ 102, 118; see 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). In cross-examination, Mr. Andrews provided additional information explaining which portion of the headers he believes are the same, but he still does not provide any explanation as to why he believes the information is copied. See, e.g., Ex. 2007 at 111:3–25. The same is true of Petitioner’s Reply, which reiterates Mr. Andrews’s deposition testimony, but still fails to provide any reason as to why Coffee’s charts or Mr. Andrews’ testimony necessarily means that Coffee copies a portion of the header from the received message to the response message. See Continental Can Co. U.S.A., Inc. v. Monsanto Co., 948 F.2d 1264, 1269 (Fed. Cir. 1991) (“Inherency . . . may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”). And, despite Petitioner’s identification of a “Header” listed in Tables 58 and 63, Coffee does not expressly describe the header or part of the header as being copied from the received message to the response message. The Petition and Mr. Andrews also state that “if Coffee did not employ such copying, the response message would not automatically include information extracted from the received message.” Pet. 38 (citing Ex. 1003 ¶ 118). But, Coffee does not expressly describe the header as being “extracted from the received message” or describe automatically including the header in a response message to make the leap argued by Petitioner and Mr. Andrews. Accordingly, on the full record before us, we find that Petitioner has not established that Coffee explicitly or inherently discloses copying the header or header information and we do not credit Mr. Andrews’ testimony, discussed above, because he fails to provide the underlying factual basis for the opinions offered.” slip op. at 43

Cir. 2019) (“We do not find any error in the Board changing its understanding of the teachings of [a prior art reference] from the institution decision to the final written decision. ‘The Board is not bound by any findings made in its Institution Decision. At that point, the Board is considering the matter preliminarily without the benefit of a full record.

Samuels, 812 F.3d 1056, 1068 (Fed. Cir. 2016))). Coffee does not explain the process by which the IOD of the received message is included in the response message; rather, Coffee just states that the response message “contains the IOD of the message being answered.” See, e.g., Ex. 1005, 56:63–67 (see full text quoted above). In particular, although Coffee attributes certain actions to the operator, the lack of attribution to the operator does not necessitate that the only viable possibility remaining is that Coffee copies the IOD from the received message to the response message. Even if it may be said that Coffee probably (or possibly) copies the IOD, that probability is not sufficient to find that Coffee necessarily copies the IOD. See Continental Can, 948 F.2d at 1269 (“Inherency . . . may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”).7 Additionally, on the full record before us, we determine that Mr. Andrews’s testimony, as with his testimony as to copying of the header and selected response, fails to provide any factual or underlying support for his opinions expressed therein. See Ex. 1003 ¶¶ 100–102. In particular, the leap occurs in paragraph 102, where Mr. Andrews takes the fact that some information (at least the IOD) from the received formatted message is included with the response message to opine that this means the information is “copied over.” Id. ¶ 102. But, again, Coffee is silent. And because Mr. Andrews did not provide any underlying factual basis for his opinion, we do not credit his testimony as to copying the IOD. 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”).” slip op. at 48

See id. at 62–70. None of Petitioner’s discussion, however, explains how the combination of Coffee and Heijden remedies the deficiencies that we identified regarding Petitioner’s challenge based on Coffee. In particular, Petitioner does not assert or explain how the teachings of Heijden would be applied to Coffee such that Coffee would then copy or fill in the specific information from Coffee’s received message to Coffee’s response message, particularly as pertains to the header, Response, and IOD fields (which Petitioner relied on in the first ground), or any other information field from Coffee. The same is true of Mr. Andrews’s testimony. See Ex. 1003 ¶¶ 214–231. Additionally, it appears that Petitioner’s analysis of the combination of Heijden and Coffee maintains the position that Coffee copies information fields. See Pet. 70 (“Given that Coffee’s system already implements field mapping to copy information fields . . . .”). And, Mr. Andrews’s testimony similarly maintains that Coffee copies information fields. See Ex. 1003 ¶ 229 (“Coffee also discloses (at least inherently) field mapping by describing that data is copied from fields in request messages into corresponding fields in response message.”). But, as we explain in detail in the context of Petitioner’s challenge based on Coffee, Petitioner has not shown sufficiently that Coffee copies or fills in information from a received message to a response message. Thus, we do not find and Petitioner does not allege that Ground “1B” fills the gaps identified in Petitioner’s Ground “1A.”10 Accordingly, we determine that Petitioner has not established, by a preponderance of the evidence, that the combination of Coffee and Heijden would have rendered the subject matter of claims 1–4, 7–9, and 12 unpatentable.” slip op. at 60

      “the output conductor of a battery cell appears “simple” and that the proposed modification to Brown may be one of a small set of possible options. But that does not remove Petitioner’s obligation to explain why a person of ordinary skill in the art would have had some reason to make the modification to the prior art that has been proposed. Requiring a petitioner to articulate a reason to modify the prior art guards against hindsight evaluation of a modification which may only appear obvious after the fact. For this reason, the Supreme Court has noted that “there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness,” and that “[t]o facilitate review, this analysis should be made explicit.” See KSR, 550 U.S. at 418 (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Here, after evaluating the entirety of the factual record adduced at trial, we cannot conclude that Petitioner has set forth a sufficiently supported reason why a person of ordinary skill in the art would have modified Brown. First, we agree with Patent Owner that Petitioner’s articulated goal of maximizing the volume of active material in the cell is undercut by the modification it proposes. As Petitioner’s expert Mr. Juzkow admitted, relocating Brown’s output conductor to the bottom of the cell would reduce the volume available for active material by approximately one percent. While we do not disregard Mr. Juzkow’s subsequent testimony that other modifications to Brown’s cell (such as removal of the central screw cavity) could compensate for this loss in volume, the fact remains that Petitioner did not propose these additional modifications in the Petition. It is incumbent on Petitioner to set forth all modifications to the prior art it plans to rely on, and justify why a person of ordinary skill in the art would have had reason to make them, so that we may fully evaluate whether it would have been obvious to do so. In any event, even if we were to accept Mr. Juzkow’s late assertion of other modifications that could be used to compensate for the loss in volume of active material, the fact remains that it is these other modifications that would be serving the motivation proposed by Petitioner of maximizing the volume of active material; relocating the output conductor would have no positive effect towards this modification. Thus, we conclude that Petitioner’s expressed motivation of maximizing active material volume has no rational relationship to the modification of Brown that is central to its Petition, of relocating the output conductor from the side of the casing to the bottom.” slip op. at 24

Sur-reply 1. To determine whether a claim is unpatentable for obviousness to one of ordinary skill in the pertinent art, we consider “the differences between the subject matter sought to be patented and the prior art.” 35 U.S.C. § 103(a) (2006); see also KSR Int’l Co. v.

Further, the specification informs that “[o]ne of skill in the art will recognize that these compositions are not intended to be limiting, and variations in ingredients and proportions can be made without departing from the spirit of the invention.” Ex. 1001, 3:13–16. Accordingly, Patent Owner’s view that an ordinarily skilled artisan would only need to rely on pre-formulated cleaning compositions and reported safety information, without “their own chemical knowledge,” is inconsistent with the disclosure of the ’912 patent. Sur-reply 2–3. An ordinarily skilled artisan, as required by the ’912 patent, would understand the nuances of the chemicals required by the terms of the claims.

Sumitomo Elec. U.S.A., Inc., 868 F.2d 1251, 1257 (Fed. Cir. 1989)). Particularly, the MPEP explains that: If the body of a claim fully and intrinsically sets forth all of the limitations of the claimed invention, and the preamble merely states, for example, the purpose or intended use of the invention, rather than any distinct definition of any of the claimed invention’s limitations, then the preamble is not considered a limitation and is of no significance to claim construction. Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305 (Fed. Cir. 1999). Based on the information presented on this record, we determine that nothing in the body of claim 1 supports a determination that the “cleaning” clause of the preamble represents an additional method step of the claimed invention. Ex. 1001, 3:23–24. To the contrary, the body of the claim fully and completely sets forth all of the required method steps of the invention, as well as the components of the required composition.

Specifically, independent claim 1 comprises three method-step limitations, namely, “providing a composition,” “applying the composition to a surface,” and “removing the composition . . . from the surface.” Id.

      “To be clear, claim 1 requires removing a “released cementitious material” from “a surface.” Id. at 3:28–4:2. Petitioner provides no persuasive reason why an ordinarily skilled artisan would have understood the term “cementitious material” to include “an efflorescence”—indeed, as just noted, the ’912 patent expressly distinguishes those two materials. Id. at 2:59–61. Claim 1 does not broadly encompass a step of removing a released efflorescence from a cementitious material, but is limited to by its plain terms to removing a “released cementitious material” from “a surface.” Id. at 3:28–4:2; see also id. at 2:61–62 (distinguishing “an efflorescence” from “cementitious materials”). In a nutshell, the claim language does not explicitly or implicitly support a construction that broadly encompasses a method of “applying the composition to a surface” of a cementitious material to “release” an efflorescense (id. at 3:28–29), even though one embodiment seems to allow for such use (id. at 2:38–39, 2:59–61). Taking account of the totality of the information presented, we determine that construing “surface” and “cementitious material” using the examples in the majority of the embodiments provided in the ’912 patent specification is necessary to “tether the claims to what the specification[] indicate[s] the inventor actually invented.” Retractable Techs., Inc. v. Becton, Dickinson & Co., 653 F.3d 1296, 1305 (Fed. Cir. 2011).

Accordingly, on this record, we construe claim 1, and each other challenged claim through dependence from claim 1, to require a step of applying a composition to “a surface” structurally separate and distinct from the “cementitious material” that is released and removed “from the surface.” Id. at 3:28–4:2.” slip op. at 18

Although the background section of the ’912 patent describes the “removal of water-insoluble cementitious and lime materials” as “a difficult process,” Petitioner directs us to no evidence sufficient to establish that calcium carbonate is “a cementitious material” within the meaning of claim 1. Ex. 1001, 1:13–14, 3:28–29; see Pet. 22; Reply 14 (totality of Petitioner’s information on point).

Reply 14; see Pet. 22 (relying on Sargent’s disclosure of the removal of “calcium carbonate”); see also Ex. 1003 ¶ 103 (conclusory opinion cited at Pet. 22 and Reply 14). Further, Petitioner assumes that the “applying” and “removing” steps of claim 1 are satisfied by Sargent’s application of a composition “to a surface of a cementitious material to release a portion of the cementitious material therefrom.” Pet. 16 (Petitioner’s emphasis). Specifically, Petitioner argues that Sargent teaches the removal of released cementitious material from the surface because an ordinarily skilled artisan “would understand that a result of Sargent’s rinsing process is to remove the composition by rinsing with water, which will also release at least a portion of any cementitious material, such as calcium carbonate, dissolved from the surface.” Id. at 22 (citing Ex. 1006, 6:57–7:2; Ex. 1003 ¶ 103).

See supra II.C.2.

      “We agree with Dr. Glew’s testimony that Hong, like Barber, does not suggest that a filter is required to protect a DC power source applied to a target from an RF power source applied to substrate. Ex. 2009 ¶ 152. We further agree that, rather than supporting Petitioner’s position, Hong supports Patent Owner’s position that at the time of the invention, one of ordinary skill in the art would not have thought that RF coupling into a remote pulsed DC power source was a concern or that it would have been desirable to place a filter between the DC power source and the substrate. Id. ¶ 153.” slip op. at 39

    Claims 1–21 were not shown unpatentable because the petitioner failed to establish the claimed narrow band-rejection filter or a sufficient reason to add one to Barber’s system.

      “In our Decision on Institution, we adopted Petitioner’s proposal regarding the level of one of ordinary skill in the art, except that we deleted the qualifier “at least” to eliminate vagueness as to the appropriate amount of relevant experience. Inst. Dec. 10 (noting that the qualifier expands the range without an upper bound, i.e., encompassing an unlimited amount of years of experience, and thus, does not meaningfully indicate the level of ordinary skill in the art).” slip op. at 10

      “Neither Petitioner nor Patent Owner assert that construction of any claim term is required to resolve any issues in dispute. See Pet. 11 (citing Ex. 1002 ¶ 54); PO Resp. 10–11. In our Decision on Institution we invited the parties to address whether the claim term “providing an RF bias that corresponds to the narrow band rejection filter to the substrate” requires that (1) the frequency of the RF bias be the same as the frequency at which the filter operates or whether (2) the frequency of the RF bias could be a shift from the frequency at which the filter operates. Inst. Dec. 37–38. Patent Owner states the term should be construed according to its plain and ordinary meaning, which the parties in the copending litigation allegedly agreed requires the claimed filter “to have a rejection band set at a frequency of the RF bias power supply.” PO Resp. 10 (citing Ex. 2021; Ex. 2022, 7–10). Petitioner “disputes PO’s suggestion of ‘agree[ment] (EX 2022, 10)” but argues that Patent Owner’s “positions are not dispositive because they do not distinguish the prior art.” Reply 1. On the full record now before us, we agree that express construction of this term is not necessary as resolution of the present dispute does not turn on whether the frequency of the RF bias is the same as, or a shift from, the frequency at which the filter operates. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (noting that “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’”) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)).” slip op. at 11

      “narrow band-rejection filter (aka notch filter).” Pet. 22–23. Petitioner’s expert, Dr. Subramanian, testified that the difference between a narrow band-rejection filter and a band-rejection filter depends on the relationship between the bandwidth and the center frequency. See, e.g., Ex. 2030, 95:15– 21 (explaining that the bandwidth is “much, much, much smaller than the center frequency”). There is inadequate evidence that the bandwidth of Hirose’s filter is sufficiently narrow to constitute a narrow band-rejection filter. Rather, the evidence of record shows that Hirose’s filter is a band-rejection filter, not a narrow band-rejection filter.” slip op. at 29

    • Novelty / Anticipation (§102) › Prior-art status of a reference › Patents / published applications (effective date, provisional support)Not reached

      “Petitioner met its burden of production to demonstrate that Hirose, which has a filing date prior to the filing date of the ’657 patent, was prior art by asserting Hirose was prior art under § 102(e). See Dynamic Drinkware, 800 F.3d at 1379. Hirose’s earlier filing date shifts the burden of production to Patent Owner to produce evidence supporting a date of invention before Hirose’s filing date. See id. With its Response, Patent Owner presents evidence it contends shows a date of conception of claims 1–8 and 10–21 prior to July 18, 2001, followed by reasonably continuous diligence. For the purposes of this decision, we need not determine whether Hirose qualifies as prior art, because, as explained below, even if Hirose qualifies as prior art, Petitioner has not sufficiently shown that all of the asserted claims would have been obvious over the grounds asserting Hirose.” slip op. at 18
