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.

    “Kwatra teaches, at Equation 7, minimizing velocity and acceleration of a function representing camera path (P). FF ¶¶ 6, 8–9. Kwatra does not state that this camera path function considers rotation. Rather, the words “camera path” suggest x, y, z movement of the camera rather than rotation of the camera. Dr. Foroosh’s testimony that Kwatra’s minimization of a smoothed camera path does not result in minimizing rotational velocity and acceleration is credible because this testimony is consistent with Kwatra as a whole and consistent with the other evidence of record. Id. ¶ 10. Kwatra recognizes that image rotation angle (“θ”) may not remain smooth. Id. ¶ 12. But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14.

Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

    “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

    “Given the teachings of the specification, we agree with Patent Owner that a low-light high-pass parameter is a parameter of a smoothing function that favors high frequencies (high pass) when exposure times are long (low light).

Although we acknowledge Petitioner’s position that the specification provides other ways or considerations in implementing a smoothing function, based on our above analysis of the specification, we find that the specification describes the lowlight high-pass parameter as a specific component of a smoothing function.

    “position and a real device position. Id. at 18:27–40. In other words, the blur is addressed by analyzing the image to identify motion and then shifting the image. Shi, however, does not disclose how its parameter is based on low light (or the long exposure times indicative of low light). In its Petition, Petitioner asserts that a person of ordinary skill in the art would understand that “blurs can be caused by low light conditions.” Pet. 28 (citing Ex. 1003 ¶ 111). Although this is true, that does not mean that Shi’s blurs are identified by a parameter that considers low light. As we just described, Shi identifies the blur by quantifying the amount of motion of the points in an image, not by identifying low light. This is simply a different way to determine the presence of motion blur. In Shi, blur is measured, whereas in the ’840 patent, it is inferred based on low-light conditions (e.g., by observing the exposure time). See, e.g., Ex. 1007, 18:7– 26; Ex. 1001, 19:12–26. In its Reply, Petitioner does not point to any further disclosures. Accordingly, we find that Shi does not disclose the “low-light” aspect of the claimed low-light high-pass parameter. This is sufficient to determine that Petitioner’s ground does not meet all claim limitations. Similarly, we find that Shi does not disclose the “high-pass” aspect of the parameter. Shi’s blur compensation uses a spherical interpolation to modify the image. Ex. 1007, 18:27–40. The low-light high-pass parameter, as we have construed the term, allows more high frequencies. To allow more high frequencies, this necessarily means either allowing fewer low frequencies, or allowing more high frequences as opposed to some counterfactual situation in which fewer high frequencies were going to be allowed. See Ex. 2020, 94:23–95:15; Ex. 2022. We are directed to no persuasive evidence from Petitioner that Shi’s spherical interpolation favors high frequencies over low frequencies. Accord Ex. 2018 ¶ 107 (Patent Owner’s expert stating that Shi’s spherical interpolation “reintroduce[es] both high- and low-frequency motion”). Even if Shi allows the viewing window to track the camera position “consistent with the natural blur in the image” (Ex. 1007, 17:63–67), we are not provided with sufficient evidence to conclude by a preponderance of the evidence that providing a similar visual goal as a high-pass parameter (Ex. 1001, 22:16–18, “the output motion may include high frequencies that mask motion blur”) is the same as having a high-pass parameter. Again, merely preserving high frequencies is not the same as having a “high-pass parameter” because, as construed, a “high-pass parameter” also involves some degree of attenuation of low frequencies or relative increase of high frequencies. Accordingly, we find that Shi does not disclose the “high-pass” aspect of the claimed low-light high-pass parameter.” slip op. at 18

    “Petitioner does not establish that Mauer sends calls to voicemail based on the two determinations claim 1 recites. Resp. 55–56. In particular, as we explain above, claim 1 requires making use of the DPR after first determining the second mobile subscriber is not located within a first wireless coverage area based on HLR and VLR information and also determining that the second mobile subscriber is not located within a second wireless coverage area based on certain CLR information. The Petition, at best, attempts to establish that Mauer directs to voicemail when a “communication session cannot be established over the first or second wireless network.” Pet. 37. But a general determination that a “communication session cannot be established” does not teach or suggest claim 1’s specific requirements that first, the DPR is utilized in the specific circumstance that the second mobile subscriber is not located within the first wireless coverage area (with this determination being made based on HLR and VLR information), and second, that the DPR is also not located within the second wireless coverage area (with this determination being made based on CLR information).

    “We find Patent Owner’s argument persuasive. Indeed, it is unclear how Petitioner’s proposal accounts for the types of problems encountered in the art or prior art solutions to those problems. See Daiichi Sankyo, 501 F.3d at 1256 (identifying these factors, among others, as “a guide to determining the level of ordinary skill in the art”). Nor does Petitioner, in its Reply, address, let alone rebut, Patent Owner’s arguments that a person of ordinary skill in the art would have had some experience and/or knowledge in internet advertising. See generally Pet. Reply. Patent Owner proposes that a “person of ordinary skill in the art would have a bachelor’s degree in computer science or a similar major involving computer programming (or at least four years of practical computer programming experience) and at least two years of experience (in or out of college) in the field of internet advertising.” PO Resp. 12 (citing Ex. 2045 ¶54). We agree that a person of ordinary skill in the art would have some experience in internet advertising, although we fail to see why one year would not be enough to familiarize sufficiently a computer scientist and/or programmer with the types of problems encountered in the art or prior art solutions to those problems. Based on the competing proposals, arguments, and evidence before us, we adopt and apply the following level of skill in assessing Petitioner’s challenges to the patentability of the claims of the ’329 patent: a person that would have had a bachelor’s degree in computer science, computer engineering, or electrical (or similar) engineering with about three years of experience being in the field of internet advertising.” slip op. at 10

Although Petitioner’s citation is off by one paragraph, Petitioner’s response about what Harkins teaches is correct. See Ex. 1004 ¶29 (“The present invention may be implemented for provision of virtually any type of advertising (e.g., print, radio, television, Internet, billboard, etc.) via any type of advertising medium (e.g., newspaper, magazine, radio broadcast, Web pages, billboards, etc.) without departing from the scope of the present invention.”). We find that Harkins is from the same field based on its express statement that it is applicable to “virtually any type of advertising” and “any type of advertising medium,” including “Web pages.” Ex. 1004 ¶29. Further, even if this were insufficient to place Harkins in the same field as the ’329 patent, we find that Harkins is reasonably pertinent to the particular problems with which the ’329 patent inventors were involved.

See Paper 21, 3 n.1 (expunging the Krassner publication and stating that it “need not -- and indeed may not -- be re-filed under a new exhibit number”). Apart from the portions of Dr. Smedley’s second declaration and Dr. Madansky’s declaration opining that Badros teaches the “determination” limitation, we dismiss the Motion to Exclude as moot. obviousness determination generally requires a finding that “all claimed limitations are disclosed in the prior art’.” (citing PAR Pharm., Inc. v.

If that were the case, then Petitioner should have made its argument in the Petition. Section 312(a) of Title 35 is titled “Requirements of Petition,” and it specifies that a petition must identify, among other things, “the evidence that supports the grounds for the challenge to each claim, including . . . (B) affidavits or declarations of supporting evidence and opinions, if the petitioner relies on expert opinions.” 35 U.S.C. § 312(a)(3); see also 37 C.F.R. § 42.104(b)(4)–(5) (“The petition must specify where each element of the claim is found in the prior art patents or printed publications relied upon; and . . . the supporting evidence relied upon to support the challenge.”). Thus, “Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.” Board’s Consolidated Trial Practice Guide, 73 (Nov. 21, 2019).7 Dr. Smedley’s testimony in his second declaration, that “Badros discloses Patent Owner’s ‘viewability test’” (Ex. 1027 ¶11), is clearly evidence to make out a prima facie case of unpatentability. The same is true of Dr. Madansky’s testimony that she agrees with Dr. Smedley in this regard. Ex. 1026 ¶4.” slip op. at 25

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.

    “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

They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
