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.

    “specification explicitly includes sensors similar to those in the prior art in support of their argument that the claimed “predetermined cycle” must not exclude the use of such sensors. Pet. Reply 15 (citing Ex. 1001, 32:55–33:7, 40:66–41:5, 44:9–29). We reviewed the portions of the specification cited by Petitioner. We agree with Patent Owner that one excerpt discussing sensor use appears to be directed to triggering the predetermined cycle rather than causing timing changes during the cycle itself (Ex. 1001, 32:55–66) (describing use of a pressure sensor to “determine when the vacuum channel 3 is clogged by a thrombus and automatically perform the unclogging procedures described herein”), while another excerpt discusses a sensor that Petitioner that the ’402 patent discusses the use of sensors to “tune” the system and that such “tuning” can be done statically (setting the cycle timing in advance) or dynamically (adjusting the timing during the cycle itself). See Ex. 1001, 48:19–49:50. Overall, we find that these disclosures involving sensors demonstrate that sensors may be used in various ways in different embodiments. However, none of these disclosures explicitly discuss the use of sensors in conjunction with a “pre-determined cycle.” Therefore, we find that the ’402 patent specification’s discussion of “sensors” are not particularly informative as to the appropriate construction of a “predetermined cycle” and do not outweigh the other explicit disclosures of “predetermined cycle” in the patent. We next turn to the other intrinsic evidence discussed by the parties — the prosecution history. As discussed by Patent Owner, in the Notice of Allowance, the Examiner found that Garrison did not teach or suggest a “predetermined cycle” because Garrison’s controller “changed the cycle of opening and closing the valves based on feedback from sensors.” Ex. 1004, 86. We acknowledge that the patent applicant filed subsequent comments during prosecution in which they stated that they “do[] not concede that the Examiner’s characterizations of the terms of the claims and the prior art are correct.” Id. at 29. However, we agree with Patent Owner that the importance of the Examiner’s statement in the Notice of Allowance does not rely on it being an express disclaimer (a standard which it does not meet). PO Sur-reply 8. We also considered Petitioner’s contention that the Examiner’s interpretation of Garrison may have been in error (PO Resp. 16); however, even if this were true, the Examiner’s statement still provides helpful insight into how the Examiner was interpreting the term sensors to change the opening and closing of valves during a cycle was not a “predetermined cycle.” Id. at 86. In sum, we find that Patent Owner’s proposed construction is consistent with the usage of the term “predetermined cycle” in the ’402 patent specification and prosecution history. Thus, after considering all of the cited evidence, we construe “predetermined cycle” to mean that “the timing of the sequence of valve operations in the cycle is determined beforehand, i.e., fixed, rather than varying based on feedback after operation begins.”” slip op. at 14

    “2.

Reply 1–8; PO Resp. 22–24; PO Sur-Reply 2–6.

    “We agree with Patent Owner that neither Petitioner nor Mr. Brown propose any combination of Yang and Mullins that does not include Mullins’s pressure sensor in order “to control fluid flow in and out from the distal end of the catheter.” Indeed, in addressing the “predetermined cycle” limitation, Mr. Brown contends that Mullins discloses a “cycling controller that ‘varies aspiration pressure according to sensed pressure within the catheter lumen.’” Ex.1005 ¶¶ 131–32 (citing, e.g., Ex.1008, 27:40–28:20 (“[a] novel aspect of this pump system is the incorporation of feedback into the pump algorithm in order to produce more effective pressure cycling”)). This use of a sensor to change pressure during a cycle, is not a “predetermined cycle” under our construction. combinations is its discussion of distal end flow control, not for its sensors.” Pet. Reply 17 (citing Ex. 1035 ¶ 83). However, Petitioner’s obviousness grounds rely on the combination of Yang and Mullins, especially with regard to Mullins’s disclosure of “a controller” in order “to control fluid flow in and out.” As discussed above, Mullins relies on the sensor-feedback approach in order to control flow and we find that Petitioner has not presented persuasive evidence of how the combined disclosures of Yang and Mullins would control flow without using Mullins’s sensor feedback approach. See W.L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540, 1550 (Fed. Cir. 1983) (error to “consider[] … references in less than their entireties, i.e., in disregarding disclosures in [them] … that diverge from and teach away from the invention”). Therefore, we determine that Petitioner has not sufficiently shown that the combination of Yang and Mullins discloses or renders obvious “a controller configured to open and close the vacuum valve and the vent valve in a predetermined cycle to change a level of vacuum at the distal end of the catheter and to control fluid flow in and out from the distal end of the catheter.” Accordingly, having considered the parties’ respective evidence and arguments, we find that Petitioner has not shown by a preponderance of the evidence that claim 1 of the ’402 patent would have been unpatentable as obvious over the combination of Yang and Mullins.” slip op. at 27

Although Figure 6(b) “displays different items” (Ex. 1005 ¶ 109) such as the depictions of people (Lauran and Chris) and partly cloudy weather, Chae does not suggest that selecting these graphics causes display of an application. See PO Resp. 21. Petitioner contends that an ordinary artisan would have understood that selecting one of Chae’s graphics items must cause display of an application (see Pet. 55; Pet. Reply 11), but Chae does not teach or suggest this feature. As Dr. Cockburn persuasively testifies, “nothing in Chae indicates that the icons displayed in Figure 6(b) are dynamic or change in any way in response to content in the corresponding applications, and that the icons when selected causes display of the corresponding applications.” Ex. 2003 ¶ 46. The mere possibility that Chae’s generic graphical objects could perform a function is speculation because nothing in Chae teaches that selecting that graphical object would display a corresponding application. See id. The display of icons in Figure 6(b) does not inform the person of ordinary skill in the art whether the item has to indicate or contain content from an underlying application, and also whether it is selectable to get to that corresponding application as required by the claims. See Tr. 32:21–33:3. Petitioner’s reliance of the testimony of Dr. Rosenberg (see Ex. 1003 ¶ 91) is unpersuasive because Dr. Rosenberg merely restates the Petitioner’s assertions without reliance on persuasive evidence of record. See Xerox Corp. v. Bytemark, Inc., IPR2022-00624, at 5 (Feb 10, 2023) (Vidal, Dir.) (“[T]he Board was correct in giving little weight to Petitioner’s expert because the expert declaration merely offered conclusory assertions without underlying factual support and repeated, verbatim, Petitioner’s conclusory arguments.”). When addressing Chae’s three graphics in Figure 6(b) during cross-examination, Dr. Rosenberg testifies that “[t]hey’re not a numbered element, so they’re not spoken about specifically those three ones”). Ex. 2005, 56:9–14, 54:21–22 (“Chae doesn’t talk about the weather icon”). Further, the final record does not support Dr. Rosenberg’s testimony that a person of ordinary skill in the art would have understood that “part of the well-known functionality of widgets was that selecting a widget would cause ‘display of an application corresponding to the respective user interface object.’” Ex. 1003 ¶ 91. None of the references relied upon by Petitioner discloses this alleged “well-known functionality of widgets,” nor does the evidence of record support any industry standard usage of the term widget in the appropriate timeframe. See Ex. 2003 ¶¶ 46–48. Petitioner has also not persuasively shown that selections of Chae’s SIM card icons result in the display of an application as claimed. See Ex. 1005 ¶¶ 152–154, Fig. 22; see also Tr. 43:14–17 (“the claimed interface object causes display of the corresponding application, but selection of this paragraph 152, Figure 22 widget causes selection of something different, a sim environment.”). We find Patent Owner’s position more persuasive, when Chae uses the word widget, it is not using that word to refer to something that launches into an application, but instead Chae’s widgets show use-state information related to a SIM environment. See Ex. 1005 ¶¶ 152–154; Tr. 33:3–12. Specifically, Chae discloses “widgets that show use-state information of the first and second SIMs (SIM1 and SIM2),” and “when a user selects one of [the] widgets,” it “unlocks the SIM corresponding to the dragged widget.” Ex. 1005 ¶¶ 152, 153, Fig. 3 (unlocking SIM displays home screen customized to unlocked SIM). Chae does not support that these widgets relate to the graphic items in its Figure 6(b), nor does Chae explain how its widgets could be understood as the claimed “user interface objects” of the widget screen user interface. As explained persuasively by Dr. Cockburn, “the only widgets that are described in Chae are widgets relating to the use state of the multiple SIM cards,” and “[t]hese widgets described in Chae do not correspond to applications and thus do not cause display of applications when the widgets are selected.” Ex. 2003 ¶ 46 (quoting Ex. 1005 ¶ 152).” slip op. at 25

    “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
