“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)). Petitioner cannot set forth the teachings of Taraschuk in such a piecemeal sufficiently explain why the converter of Taraschuk relies on analog pre-distortion, or explain why analog pre-distortion is encompassed by the invention recited in independent claim 1, Petitioner does not sufficiently carry its burden.” slip op. at 25

“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

“In our Preliminary Guidance, we construed “for a pharmaceutical composition” to mean “in combination with pharmaceutically acceptable excipients,” based on the ’363 patent’s definition providing that “[t]he terms ‘formulation’ or ‘pharmaceutical composition’ as used herein refers to the drug in combination with pharmaceutically acceptable excipients.” Prelim. Guid. 5–6 (citing Ex. 1001, 12:26–28; Ex. 2010, 17:11–12; Ex. 2011, 26:26– 27). We also encouraged the parties to address whether “for a pharmaceutical composition,” which appears in the preamble of substitute claims 28 and 29, is limiting, as opposed to a statement of intended use or purpose. 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.

See, e.g., Mot. 6 (“[A]llowing [Petitioner] to assume an understudy role to Ericsson, will also have little, if any, impact on the Ericsson IPR because no new grounds will be added, the schedule will not be affected, no additional briefing or discovery will be required, and no additional burdens will be placed on Patent Owner.”).” slip op. at 10

“To offer expert testimony from the perspective of a skilled artisan in a patent case—like for claim construction, validity, or infringement—a witness must at least have ordinary skill in the art.” Kyocera Senco Indus. Tools Inc. v. Int’l Trade Comm’n, 22 F.4th 1369, 1376–77 (Fed. Cir. 2022). Patent Owner is correct that Dr. Lieberman’s CV on its face does not include two years in a position titled as software developer, web-based developer, or the like. See generally Ex. 1004. Dr. Lieberman, however, has a degree in “Informatique” from the University of Paris VI (Sorbonne), as Patent Owner acknowledges (Prelim. Resp. 34), and this degree is in addition to Dr. Lieberman’s Bachelor of Science degree from the Massachusetts Institute of Technology (MIT). Ex. 1004, 12–13. This University of Paris VI (Sorbonne) degree is additional education beyond the required bachelor’s degree and could have substituted for some amount of professional experience, as we note in our determination of the level of ordinary skill for this institution decision in Section II.A. slip op. at 42

“creation message to the group-surfing server 140 to create a group-surfing session (Ex. 1005, 32:9–11), a second web client 110 can “add itself to the session” by sending “a session-join message 151 to the group surfing server 140” (id. at 33:2–3). The session creation message sent by second web client, which corresponds to the recited guest device, is sufficient to teach or suggest detecting an activation associated with the synchronized browsing session at this preliminary juncture. Lebrun differs from the detecting limitation in that it does not expressly describe that the session creation message is sent by activating a hyperlink. However, Wang’s description of a second client device joining a group session via the myURL address is sufficient at this preliminary stage to address the deficiency in Lebrun. On this preliminary record, Petitioner’s showing of a rationale to combine Lebrun and Wang is also sufficient for purposes of institution. Specifically, the proffered reasoning that utilizing Wang’s designated URL address to activate a session join invitation would enable Lebrun’s group-surfing server to coordinate and manage the group-surfing session and further Lebrun’s goal of providing improved group access to web sites (see Pet. 25), is sufficient at this early stage. Patent Owner does not address Petitioner’s showing as to this limitation. See generally Prelim. Resp.” slip op. at 18

“claim construction standard employed in a civil action under 35 U.S.C. § 282(b). 37 C.F.R. § 42.100(b) (2020). Under the principles set forth by our reviewing court, the “words of a claim ‘are generally given their ordinary and customary meaning,’” as would have been understood by a person of ordinary skill in the art in question at the time of the invention. Phillips v. AWH Corp., 415 F.3d 1303, 1312 (Fed. Cir. 2005) (en banc) (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)). “In determining the meaning of the disputed claim limitation, we look principally to the intrinsic evidence of record, examining the claim language itself, the written description, and the prosecution history, if in evidence.” DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 469 F.3d 1005, 1014 (Fed. Cir. 2006) (citing Phillips, 415 F.3d at 1312–17). We construe claim terms only as relevant to the parties’ contentions and only to the extent necessary to resolve the issues in dispute. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017). Neither Petitioner nor Patent Owner propose express constructions for any claim terms. Pet. 12; Prelim. Resp. 34. For purposes of this decision, we agree that no claim terms need be expressly construed. Patent Owner arguments regarding the asserted grounds of unpatentability, however, raise particular claim scope contentions, particularly regarding “information related to the shared web browsing interaction” recited in each of the independent claims. We preliminarily address issues of claim scope in our later discussion of the asserted grounds of unpatentability.” slip op. at 12

“Accordingly, based on this preliminary record, we find Patent Owner’s assessment of “internet web browsing software development, web connectivity software development, or networking software development” to be too narrow in view of the asserted prior art that describes in large measure requesting and receiving web pages from web servers. Thus, we find that Petitioner’s assessment of “software development and/or web- based software” more appropriate for purposes of institution on this limited record. We also agree with Petitioner that additional education could have substituted for professional experience, and significant work experience could have substituted for formal education. For the purpose of this decision, for these reasons, we find that a person of ordinary skill in the art would have had (1) at least a bachelor’s degree in computer science, computer engineering, electrical engineering, or a similar field, and (2) at least two years of work experience in software development and/or web-based software. We apply that level of ordinary skill in this decision. Our decision, however, would not change, however, if we had applied Patent Owner’s proposed level of ordinary skill.” slip op. at 11

“Accordingly, there is evidence to consider in making a determination whether Dr. Lieberman possesses the requisite ordinary level of skill. We, however, need not make such a determination for purposes of this decision because it has not been necessary for us to rely on Dr. Lieberman’s declaration in this decision. “No rule requires a Petition to be accompanied by any declaration, let alone one from an expert guiding the Board as to how it should read prior art.” Belden Inc. v.

Here, the invention and prior art are presented in high-level functional terms and are easily understandable, as we indicated previously in Section II.A and as shown by our discussion of the invention and prior art throughout this decision. To determine that the Petition met the institution threshold of showing “a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition,” we have not relied on Dr. Lieberman’s declaration testimony.
