It (1) specifically states that “the instant claims require” and (2) then states what the claims require—a “‘pre-printed lottery ticket’ which has no lottery numbers associated with it at the time of customer purchase.” We fail to see how the applicant could have been more clear in stating a requirement of the Challenged Claims.

    “We do not find Mr. Hutton’s testimony particularly helpful. First, we have addressed the points raised by his testimony in our discussion above because they are largely the same as the arguments raised in Petitioner’s Reply. Second, we find his testimony entitled to very little weight because he applies an incorrect understanding of the caselaw, which mirrors Petitioner’s incorrect and arguably misleading quotations of the Federal Circuit’s decision in Quest. In particular, in paragraph 5, Mr. Hutton states the following as his understanding of the law as it applies to prosecution disclaimer: “I also understand that in order to disclaim embodiments within the specification, the statements should have some indication that the applicant intended to surrender embodiments from the specification.” Ex. 1038 ¶ 5 (emphasis added). This then leads Mr. Hutton to state: “[t]hus, in my opinion, a [person of ordinary skill in the art] would not view applicant’s statements as a disclaimer, because the applicant never stated that they intended to surrender multiple embodiments described in the specification.” Id. ¶ 13 (emphasis added). As we explained above in responding to a similar argument by Petitioner, the caselaw does not require an applicant to expressly state whether a disclaimer excludes particular embodiments of the subject specification when disclaiming claim scope during prosecution. See Quest, 924 F.3d at 1229. And, as noted above, counsel for Petitioner agreed that such a statement explicitly disclaiming particular embodiments is not required. Tr. 12:18–13:17. Third, although we have considered Mr. Hutton’s testimony, we find it “less significant than the intrinsic record in determining the legally operative meaning of” “pre-printed lottery ticket.” Phillips, 415 F.3d at 1317. In particular, we are cognizant of the Federal Circuit’s guidance that we “should discount any expert testimony that is clearly at odds with the claim construction mandated by . . . the prosecution history.” Id. at 1318 (internal quotation omitted). In this instance, for the reasons explained above, we find that Mr. Hutton’s testimony is clearly at odds with the applicant’s arguments during prosecution and that his testimony is based on a misunderstanding of what is required by the governing caselaw for prosecution history disclaimer.” slip op. at 43

    “From this description in Burrows, it is clear that index 70 has no sense of ranking, and that Burrows’ system overall has no sense of ranking prior to a query; thus, adding or deleting a webpage from the index does not change a ranking that does not yet exist. It is also clear that, if a page is flagged as deleted, it will be ignored by the query module when the query module queries the index and ranks the identified qualified pages. Id. at 15:12–16, 15:21–22. The webpage’s rank is not decreased, as the webpage is never ranked in the first place. As Mr. Occhiogrosso testifies: web page. A “polled web site” page cannot be ranked in the Burrows system because the Burrows ranking is performed only after a user query is performed. Only at that time can the Burrows system provide a ranked list (of qualified webpages) for presentation to the user. As Burrows discloses, the Automated Web Browser is robotic in nature and not associated with the queries of users. Ex. 2009 ¶ 181. Mr. Occhiogrosso’s testimony on this point is consistent with Burrows’ description, credible, and entitled to substantial weight. We have considered Mr. Lipoff’s testimony that a skilled artisan “would have understood that combining Burrows’s polling mechanism receiving no response into Kovatch would decrease the entries’ ranking or placement in Kovatch’s destination tree in order to further limit the pages that may not be of interest to the user.” Ex. 1002 ¶ 172 (citing Ex. 1006, 1:38–46). That testimony, however, is conclusory and lacks persuasive reasoning. Moreover, the passage in Burrows to which it cites (Ex. 1006, 1:38–46) does not teach or suggest decreasing the ranking of webpages.

Mr. Lipoff repeats this statement in his testimony without identifying the basis for it, rendering that testimony of little value. Ex. 1061 ¶ 24. In any case, it appears that Petitioner and Mr. Lippoff are arguing that a general notion of processing cost any time computer processing occurs would lead a skilled artisan to decrease a webpage’s rank based on response time. This is a new argument, not presented in the Petition, and is therefore forfeited and will not be considered.

Neither of these statements address the requirement in the claim that, “upon verifying the validity of the license,” the instructions are configured to “cause the licensing/reporting server to provide to the proxy” the URL.

This statement addresses only the last portion of the claim limitation. Thus, the Petition and supporting evidence (Dr. Almeroth’s declaration testimony) do not address the entirety of the location designator claim limitation. On reply, Petitioner relies on additional testimony from Dr. Almeroth. Pet. Reply 13 (citing Ex. 1024 ¶¶ 90–91). Dr. Almeroth opines that “[t]here is no practical difference between the request for streaming media content, in combination with an authorization ticket that is provided back to the network for verification; and ‘request[ing] verification . . . of the validity status of a license to the specific instance of content.’” Ex. 1024 ¶ 90. According to Dr. Almeroth, a person of ordinary skill in the art “would view them as insubstantially different, if at all, and would still be motivated to combine Sperle and Madison.” Id. Dr. Almeroth adds that “there is no reason why the combination would not be an obvious design choice.” Id. Dr. Almeroth also testifies that “there is no clear significance to the fact that the ‘steps in Madison’ are in ‘reverse order compared to the claim element’” and that a skilled artisan “would view them as insubstantially different, if different at all, and would still be motivated to combine Sperle and Madison.” Id. ¶ 91. Dr. Almeroth’s testimony does not persuasively show why a person of ordinary skill in the art—considering the teachings of Sperle and Madison— would have performed the redirector file creation and authorization differently from what Madison teaches such that, upon determining that the user was authorized, the URL is provided from the licensing server to the proxy, as required by the claim. Petitioner relies on Madison’s disclosures regarding the redirector file for teaching other elements of the claim—the proxy and the verifying of the validity status of the user license—yet fails to provide a persuasive analysis for why a skilled artisan would go beyond what is taught in Madison and provide the URL to the proxy “upon verifying the validity of the license” rather than prior to that verification. Dr. Almeroth does not point to design considerations at the time of the invention to show why the differences between the art and claimed invention are “insubstantially different” or that the modification would merely be a “design choice.” Ex. 1024 ¶¶ 90–91. Rather, Dr. Almeroth provides conclusory testimony that is not supported by any evidence contemporaneous with the claimed invention. In fact, Dr. Almeroth does not provide any technical explanation for his generic conclusions.

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

    “We determine Patent Owner’s reading of the claim limitation is the better one. The limitation begins with the verb “locating,” and it therefore makes sense that the clause would recite what is located (i.e., encryption information) and where it is located (i.e., within the requested portions of the selected stream of protected video). In other words, it is reasonable that the second and third clauses of the limitation both modify the first clause (for example, as could perhaps be expressed through the use of commas as “locating encryption information, that identifies encrypted portions of frames of video, within the requested portions of the selected stream of protected video”).10 On the other hand, Petitioner’s reading of the limitation, 10 In general, we recognize that the use of commas to set off phrases in claim drafting is not consistent. We included commas above to illustrate Patent Owner’s understanding of the claim limitation. allowing only the second clause to modify the first, while not unreasonable, makes less sense. That is, the encrypted information identifies the encrypted portions of frames, which in turn are within the requested portions of the selected stream of protected video. Reading the claim in its entirety, the encrypted portions of frames would be understood to be located within the requested portions of the stream; it does not seem necessary for the claim to expressly recite that aspect. For example, the very next limitation— limitation [m] of claim 1—refers to “each encrypted portion of the frames of video” but does not expressly recite “within the requested portions of the selected stream.” Ex. 1001, 27:58–60. Thus, when limitation [l] recites “within the requested portions of the selected stream,” it seems more likely that the clause refers to where that encrypted information is located rather than simply to indicate the obvious location of the encrypted portion of the frames of video. We therefore view Patent Owner’s reading of the claim language as the better one.” slip op. at 13

See PO Remand Br. 1 (citing PO Resp. 24–37 (the construction of “locating encrypted information . . . within requested portions”), 38–58 (referring to Patent Owner’s “common keys” argument)). 8 The Final Decision also addressed Petitioner’s Motion to Exclude (Paper 42). See Final Dec. 28–37 (granting-in-part, denying-in-part, and dismissing-in-part Petitioner’s Motion). Our determinations on that Motion were part of Petitioner’s appeal to the Federal Circuit. See Paper 52. Because the Federal Circuit did not address this aspect of the Final Written Decision and the Federal Circuit’s decision does not impact our previous rulings on the Motion, we maintain those rulings here. Additionally, on remand, Petitioner requested authorization to file a motion for sanctions, which we held in abeyance until the parties’ briefing on remand was complete. See Ex. 3003, 1. Petitioner requests sanctions because of the impropriety of Patent Owner’s remand brief, including new claim construction arguments for limitations [1j] and [1k], and prejudice to Petitioner.

Although Dr. Koralek testifies that an undergraduate education would not have been sufficient for a person to acquire ordinary skill in the art relating the ’700 Patent (Ex. 1024 ¶¶ 7–9), that testimony does not adequately account for the knowledge relating to error correction a person could acquire through practical experience.

The Specification’s disclosure that a decoder module can buffer data does not mean that buffering alone can constitute decoding. Nowhere does the Specification define “decode” to mean just “buffer.” The Specification’s use of the disjunctive, “or,” to connect these words (Ex. 1001, 6:11–14) is not enough to redefine the word “decode” to encompass buffering alone. Petitioner agrees that “[t]he ’700 Patent does not define the word ‘decode.’” Pet.

In this case, defining “decode” to encompass mere buffering would be a departure from the plain and ordinary meaning of the term as understood by a POSITA. Petitioner’s expert, Dr. Koralek, agrees that, “aside from the ’700 patent, what a person of ordinary skill would understand decode to mean, it would not be just buffering. Decoding might include buffering, but buffering by itself would not be considered decoding to a person of ordinary skill.” Ex. 2023, 73:14–20.

Because the deficiency in Petitioner’s showing also applies to the dependent claims, which inherit the “network-based portal” limitations, we conclude that Petitioner does not show that any of claims 7, 10–12, 22–24, 33–36, 38–41, 46, 49, 51–53, 55, 57, 58, or 64– 66 is unpatentable under 35 U.S.C. § 103(a) over Tanigawa and Hullfish; that any of claims 8, 9, 43, 44, 47, 48, 50, or 54 is unpatentable under 35 U.S.C. § 103(a) over Tanigawa, Hullfish, and Loveland; that any of claims 37, 42, 56, 59–63, or 67 is unpatentable under 35 U.S.C. § 103(a) over Tanigawa, Hullfish, and Takahashi; or that claim 45 is unpatentable under 35 U.S.C. § 103(a) over Tanigawa, Hullfish, Loveland, and Takahashi.” slip op. at 36

  • Expert testimonyPatent owner expert creditedDecided for patent owner

    “Dr. Rouskas (Patent Owner’s expert), who directly opines on this issue. Ex. 2005 ¶¶ 60–85. Although the record also includes a Declaration by Petitioner’s expert, Dr. Almeroth, that Declaration was filed with the Petition and neither responds to Dr. Rouskas’s opinions nor provides any testimonial evidence to support Petitioner’s positions beyond what was available at the preliminary stage of the proceeding.3 See generally Ex. 1003. In evaluating the fully developed record, we necessarily accord greater weight to Dr. Rouskas’s testimony than to Petitioner’s attorney argument as advanced in Petitioner’s Reply. See, e.g., Gemtron Corp. v. Saint-Gobain Corp., 572 F.3d 1371, 1380 (Fed. Cir. 2009) (“[U]nsworn attorney argument . . . is not evidence and cannot rebut . . . other admitted evidence . . . .”). Our evaluation also necessarily remains cognizant that “[i]n an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. 3 Petitioner filed a second Declaration by Dr. Almeroth after institution (such that it was not available on the preliminary record), but that Declaration is provided primarily as supplemental evidence under 37 C.F.R. § 42.64(b)(2) to address objections by Patent Owner to the authenticity of various other exhibits. Ex. 1039 ¶ 2. Dr. Almeroth’s second Declaration otherwise merely incorporates Dr. Almeroth’s “technical opinions” by reference to his first Declaration, without providing any further facts or expressing any further opinions that bear on the merits, including claim construction. Id. ¶ 1. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)). This burden never shifts to Patent Owner. See Dynamic Drinkware, LLC v. National Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (citing Tech. Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1326– 27 (Fed. Cir. 2008)) (discussing the burden of proof in inter partes review). Against this backdrop, we address the parties’ arguments, ultimately concluding that Patent Owner articulates the more persuasive position that a “network-based portal” as recited in the claims is limited to residing at a server side of a network.” slip op. at 15

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Petitioner proposes that a person of ordinary skill in the art “would have had a Bachelor’s degree in Computer Science, or an equivalent field, and three to five years of experience working with Internet communication systems.” Pet. 25. According to Petitioner, “[a]dditional education might compensate for less experience, and vice-versa.” Id. Dr. Almeroth supports this articulation. See Ex. 1003 ¶¶ 92–97. Patent Owner does not propose any different expression of the level of ordinary skill, and Dr. Rouskas testifies that he has “employed Dr. Almeroth’s definition” in his Declaration. Ex. 2005 ¶ 21. Because we find Petitioner’s proposal reasonable, consistent with the level of skill reflected by the prior art, and supported by the testimony of Dr. Almeroth, we adopt it for purposes of this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art).” slip op. at 12
