“c. Analysis “A claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros. v. Union Oil Co. of California, 814 F.2d 628, 631 (Fed. Cir. 1987). We are persuaded by Patent Owner’s argument that Avellan does not anticipate claim 1 because it does not assemble a media stream of multimedia items using the recited screen captures. See PO Resp. 26–29. We agree with Patent Owner that the plain language of the claim requires more than transmitting individual media items. Sur-reply 21. To the extent that Avellan captures images, those images do not meet the claimed requirements for a “temporal sequence of screen captures” in the independent claims, which must (1) be of the web page rendered by a browser, (2) “define all the content of the web page at a given time,” (3) “illustrate a dynamic change of at least a portion of the content over time” when two of them are compared, and (4) used to assemble “the at least one media stream.” Rather, the record better supports Patent Owner’s argument that Avellan transmits the multimedia items separate from any media stream assembled from screen captures.

Petitioner does not allege that the additional references—Durante, Ma, Suzuki, Wanamaker, Heikens, Matthews, or Wilsher—teach or suggest the “temporal sequence of screen captures” recited in claim 1. Rather, Petitioner’s reasoning in the challenges to the dependent claims pertaining to the screen captures mirror the rationale presented in the independent claim.

Instead, we agree with Patent Owner that Suzuki’s irregular-surface smoothing describes covering defects, not suppressing the underlying cathode’s topography. PO Sur-reply 5. The smooth-surface passage that Petitioner highlights comes immediately after two sentences describing inevitable “defects,” “pinholes,” and “foreign matter” on the cathode surface and before a sentence describing “ensuring the formation of the layer 22, which is substantially defect-free.” Ex. 1012, 5:52–67. Suzuki’s organic barrier 20 “makes a smooth surface” by covering defects because the defects are the only source of the “irregularity” that Suzuki refers to here. Id.

Reply 2 (citing 01119-Petition, 26–33, substantially identical to Pet. 32– 40). However, again, the Petition does not explain an alternative theory in which Chaudhri supplements Ahn’s menu functionality to move that menu onto the screen, as opposed to teaching visual cues provided by gradual changes of the display during a gesture or the visual cue that an unlock image may provide during the unlock gesture. See Pet. 14–18 (describing Chaudhri teaching “visual differentiation” or “transitioning an optical intensity” between a user-interface object and the background, based on, e.g., transparency), 35–40 (same). In Reply, Petitioner adds evidence to attempt to support its contention that the combination teaches a menu following a user’s finger during a dragging gesture, involving references to Chaudhri’s discussion of a visual cue, further discussing Chaudhri’s unlock image.

“Even assuming, arguendo, we were to credit Petitioner’s arguments that “it is sufficient for the prior art to render obvious a mapping exhibiting the deltas features; the prior art need not calculate the deltas themselves” (Pet. Reply 11) and that “Dr. Dallesasse agrees that modeling a Mach- Zehnder modulator as exhibiting a sinusoidal response—as Dr. Blumenthal did—was ‘reasonable’ ‘to a first order’” and “[a]ny other sources of non-linearity would merely be less significant, ‘second order effects,’” (id. at 12– 13), Petitioner does not sufficiently show that the sinusoidal response curve would look like the one Dr. Blumenthal proposes. Dr. Blumenthal asserts, without specifically or credibly explaining why, that a person of ordinary skill in the art would have selected a region of the sinusoidal response curve that includes an inflection point such that deltas both decrease and increase over some portion of the curve being linearized. See Ex. 1003 ¶¶ 173–174 (scaling and shifting a sinusoidal response curve so that the curve contains an inflection point within the linearized region, but without adequately explaining the evidentiary basis for these selections); id. ¶ 52 (opining that “in the close vicinity of the center of the positive or negative inflection regions, otherwise known as the Quadrature point, the modulator is almost would have included regions on both sides of an inflection point). If a person of ordinary skill would have selected a region of the sinusoidal response curve on only one side of an inflection point, the evidence does not suggest that such a mapping would satisfy both limitations 1.8 and 1.9. 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. 52 (citing Ex. 1003 ¶ 196). The analysis for 13.8 is incorporated by reference in 13.9. See Pet. 53–54. 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. Petitioner’s obvious-to-try rationale is insufficient to show that a person of ordinary skill would have used a digital-to-digital-mapping in which there are regions in which the deltas are both decreasing and increasing. Moreover, Petitioner’s Reply includes positions not supported by a Reply Declaration from Dr. Blumenthal and thus, constitute attorney argument that is not sufficiently supported by evidence.

“Inst. Dec. 35 (citing Ex. 1006, 8:2, 8:8). 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 ’998 patent specification distinguishes analog pre-distortion (see Ex. 1001, 1:64–2:36) and the prosecution history specifically distinguishes analog pre-distortion from the claimed approach (see Ex. 3001, 172).6 We find persuasive Dr. Dallesasse’s testimony that “a person of ordinary skill in the art reading the [’998] patent would understand that th[e] [claimed] approach of mapping, based on the converter output pattern differs 6 Ex. 3001 is a portion of the prosecution history of U.S. Patent No. 11, 133, 872, a parent of the ’998 patent. Ex. 2022 ¶ 34 (citing Ex. 1001, 2:5–9 (’998 patent disclosing common, prior art solutions such as “an analog pre-distortion circuit to feed the modulator”); Ex. 1005, 2:53; Ex. 1006, 7:67–8:5, Fig. 6); Ex. 1001, 2:35– 37(the ’998 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 parent ’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 claims, as the ’998 Patent itself admits.” Id. ¶ 79 (citing Ex. 1001, 2:5–9; Ex. 2009, 2; Ex. 1010, 16–48). 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. 3001, 172 (emphasis added). We interpret the quoted passage to exclude analog pre-distortion because we interpret the argument distinguishing distortion techniques––in particular, those accomplished by analog compensation function, c(t). Id. Both the ’998 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 34

“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).

“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.

“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.
