Reply 7 (quoting Ex. 1012, 5:59–67). We disagree. 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. We note Mr. Humphrey’s testimony, which we credit in this regard, that the “defects are created incidentally on the surface of the underlying layer and are generally not considered to be part of the underlying layer’s topography, which is a macroscopic property by design” and that the organic layer is not a planarization layer because it would reproduce the topography of the underlying layer.

    “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

    “Petitioner’s resurrected argument is based on a fundamental misunderstanding of § 311(b). Section 311(b) provides: “A petitioner in an inter partes review may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed cancel the claims of the ’329 patent on the basis of Badros, Harkins, and Krassner.

Even if we assume Krassner is also a “printed publication” withing the meaning of § 311(b), the same date would apply: August 13, 2019. Petitioner has not presented any evidence that the document that is Krassner was published prior to when it issued on August 13, 2019. That another document (the Krassner publication), which published much earlier, may contain the same or similar disclosure is not relevant to when Krassner was patented or published.

Although Petitioner’s citation is off by one paragraph, Petitioner’s response about what Harkins teaches is correct.

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.

    “Paper 60 (“PO Mot.

Paper 60, 9–12. Petitioner, in its Opposition to the Motion to Exclude, argues that Patent Owner’s arguments about the “viewability test” were “surprising.” Paper 62, 8. We are not persuaded by Petitioner’s argument. The “viewability test” is a claim limitation. Petitioner should have anticipated that Patent Owner would argue that limitation.

For example, Exhibit 1017 is the Krassner publication, which Petitioner unsuccessfully moved to add to the record as supplemental information. 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. TWI Pharms., Inc., 773 F.3d 1186, 1194 (Fed. Cir. 2014)). Petitioner argues that “[v]iewability tests were well known for well over a decade prior to the ’329 patent’s priority date.” Reply 9. 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

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.

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.)

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

    “alternative” or “alternative title.” Neither party contends that “alternative” or “alternative title” is a term of art with an art recognized meaning. In plain English, “alternative” as an adjective designates something that is another option, another choice. Dictionary.com (accessed June 23, 2022), https://www.dictionary.com/browse/alternative (Ex. 3002) (“affording a choice of two or more things, propositions, or courses of action,” “(of two things, propositions, or courses) mutually exclusive so that if one is chosen the other must be rejected: The alternative possibilities are neutrality and war.”). The specification of the ’179 patent also consistently uses the word “alternative” to mean something in lieu of or in place of another choice. For instance, the ’179 patent describes: Advantageously, data associated with the event can also (or in the alternative) be provided to the title provisioning engine 616. Ex. 1001, 8:15–17 (distinguishing “also” from “alternative”). A given event may cause the title provisioning engine 616 to rewrite the entire title array 618 with title strings associated with the most recent events. Alternatively, a given event may cause the title provisioning engine 616 to append title strings to the end of the title array 618. Id. at 8:24–28 (using “alternative” in mutually exclusive context). slip op. at 12

    “reproduced above, are “event messages / strings 300 (shaded in green).” Pet. 30 (citing Ex. 1006 ¶ 31). But the cited evidence does not support that assertion. Paragraph 31 of Eaton describes the referenced column simply as “associated event 300.” Ex. 1006 ¶ 31. Further, even if the column stores associated event messages, Petitioner cites nothing to show that the associated messages in server memory column 300 are the event presence notification messages discussed above in the context of limitation 1[ii]. Alternatively, Petitioner relies on Eaton’s Figure 6 embodiment. Pet. 31. Petitioner asserts (id.) that in the Figure 6 embodiment server memory 160 stores an array of event notifications, referencing an annotated version of Eaton’s Figure 6, reproduced below: Figure 6 is a block diagram of an alternate embodiment of a server memory for use within a server of the instant message communication system, and Petitioner has shaded the EVENT AN–NN column green and the words “SERVER MEMORY” red. Ex. 1006 ¶ 19. Petitioner asserts that both the TOPIC N column 540 and the EVENT AN-NN column 670 as the stored event notifications. Pet. 31 (citing Ex. 1006 ¶¶ 56–58). But the assertion is not supported by the cited evidence. Paragraphs 56–58 of Eaton do not indicate that either topic entries 540 or event entries 670 are the event presence notification messages discussed above in the context of limitation 1[ii]. In its Reply, Petitioner asserts that event presence notification message EPNM “is associated with the character strings labelled Topics [1]- [N], and using ‘Topic N’ as the example, it is tied to ‘Event[s] AN-NN’ (representing the ‘events’ from the plurality of events 180 discussed in Claim 1[i]).” Reply 22.

    “’179 Patent as provided above in Ground 1. To the extent that there are arguably any meaningful differences between those claims and Eaton’s disclosures, those differences would have been trivial and obvious modifications to make for a PHOSITA.” Pet. 49. This conclusory assertion of obviousness does not specifically identify any difference between the claimed invention and Eaton, and does not provide any reasoning or rational underpinning to support the assertion. Conclusory assertions of obviousness are insufficient to satisfy Petitioner’s burden of proof. In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016). Petitioner asserts that to the extent that Eaton discloses various, “distinct” embodiments, it would have been obvious to one with ordinary skill in the art to combine Eaton’s teachings into a single system. Pet. 49. Petitioner also asserts that one with ordinary skill in the art “would understand that Eaton discloses possible configurations and/or operations of the same system, and to the extent that it is argued or found otherwise, the functions would have been entirely obvious to combine for [one of ordinary skill in the art] given Eaton’s express disclosures.” Id. It is uncertain what distinct embodiments are referred to by Petitioner. However, even assuming that the disclosures of Eaton’s embodiments, already discussed by Petitioner, are properly combinable, there still remains the deficiencies, discussed above in the alleged anticipation of claim 1 by Eaton, relating to the step of storing the event notification in an array, the step of providing the event notification from the array to a process executed by a processor, and the step of providing an alternative title from the array to the process.

    “For purposes of this decision, we need only address the proper construction of “mounting surface,” which is disputed by the parties. Here, Patent Owner’s argument and evidence produced during trial show that Petitioner’s construction of “mounting surface” is not in accordance with the ordinary and customary meaning as would have been understood by one of ordinary skill in the art. In particular, we agree with Patent Owner that “the mounting surface having a plurality of recesses,” as recited in claim 1, means that the recesses are in the mounting surface itself. PO Resp. 10–11. As we discuss further here, this requirement cannot be satisfied by a single planar surface, as used in Petitioner’s analysis. See, e.g., Pet. 18. Both parties acknowledge the argument that the claimed recesses could be interpreted in at least two ways: The recesses could be (1) only in the packaged body, excluding the contacts; or (2) in the device as a whole.

    “For the reasons discussed in the Claim Construction Section, we disagree that the recited mounting surface can be a plane and still satisfy all the claim limitations. Supra § II.B. In particular, we agree with Patent Owner that Petitioner’s planar mounting surface does not include “recesses” at the side edges of the body as the claim requires. PO Resp. 15. Rather, the planar surface identified by Petitioner sits below the recesses in Kim’s device—i.e., “the depressions or indentations in molded resin package body 37” or the device as a whole.

Contrary to the claim’s requirement that the device itself comprise a mounting surface with “recesses and electrical contacts [that] are sized to provide offsets between said mounting surface and said electrical contacts,” both Kim’s device and the Figure 4A embodiment show recesses between the device and a flat surface on which the device is mounted.
