In the Institution Decision, we stated: To the extent Patent Owner seeks to pursue its argument that Linq3 is a real party of interest to Petitioner, even though no time bar under 35 U.S.C. § 315(b) has been asserted, Patent Owner may raise the issue of real party in interest again in its Patent Owner Response and the parties may brief and argue the issue during trial.

    “Following the block quote from Yacenda, the applicant then stated, “[b]ased on the foregoing, Yacenda’s system is directly opposite of the instant claims, as the instant claims require a ‘pre-printed lottery ticket’ which has no lottery numbers associated with it at the time of customer purchase.’” Ex. 1002, 76. This statement is clear and unmistakable. 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

    “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

    “the case law makes clear that “an indefinite article ‘a’ or ‘an’ in patent parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising’” unless an “extremely limited” exception applies. See Convolve, Inc. v. Compaq Computer Corp., 812 F.3d 1313, 1321 (Fed. Cir. 2016) (quoting KCJ Corp., 223 F.3d at 1356; Baldwin Graphic Sys., Inc. v. Siebert, Inc., 512 F.3d 1338, 1342 (Fed. Cir. 2008)). Here, claim 1 recites the transitional phrase “comprising,” meaning it is open-ended, and, therefore, the usual meaning of “a” as “one or more” would have been expected absent an extremely limited exception. In considering whether an exception applies, our review of the ’720 patent fails to indicate that the patentee intended the phrase to mean anything other than the usual meaning of “one or more.” Patent Owner asserts that “‘[t]he plain language of the claim clearly indicates only a single [list] is used’ to list multiple assets” and quotes two portions of the Specification, which state “a list of assets that satisfies criteria” and “a list of assets to which a . . . device is granted access.” PO Sur-reply 15 (quoting Ex. 1001, 12:60–67) (citing Ex. 1001, 2:23–34, 3:1–5, 4:21–23, 17:59–66). Although claim 1 of the ’720 patent recites “assets” in the plural, we fail to see how that conveys that the term “a” would have been understood as limited to “one.” Notably, neither party has identified any inconsistency, in the claims or other portions of the Specification (including the portions quoted and/or cited by Patent Owner), resulting from construing “a” as “one or more.” And, we find that there is no reason why the claims could not be met under the construction of “a” as “one or more.” Thus, we find that the ’720 patent does not “evince [ ] a clear intent to limit a or an to one.” See Convolve, 812 F.3d at 1321 (internal quotations omitted). Accordingly, we construe the term “a” in “a list of assets” as “one or more” such that the phrase “a list of assets” means “one or more list of assets.” Considering next the phrase “the list of assets” recited in limitation 1[d], the parties do not dispute that the use of the term “the” means that “the list of assets” refers back to the one or more list of assets retrieved in limitation 1[c] and discussed above. See PO Resp. 3–4; see generally Pet. Reply; PO Sur-reply 5. Similarly, the parties do not dispute that the phrase “the filtered list of assets,” recited in limitation 1[e], refers back to the list of assets resulting from the filtering step of limitation 1[d]. See PO Resp. 3–4; see generally Pet. Reply; PO Sur-reply 5. We agree with the parties that each of these phrases refers back to the previous instance of the recited terms.” slip op. at 14

    “Fundamentally, Petitioner fails to provide any reason in the Petition as to why one of ordinary skill in the art would have found it obvious to retrieve a list of assets based on Lewis. Instead of providing a reason as to why retrieving a list of assets would have been obvious, Petitioner points to a result achieved by Lewis—generating a dynamic manifest file that contains a list of URLs to container files containing content. In the context before us, pointing to a result to allege that a step in a process leading to the result would have been obvious is insufficient without also providing a reason with rational underpinning.

Here, Petitioner relies upon the result of Lewis’s process—generating a dynamic manifest file containing a list of URLs—as the only basis as to why a previous step in the claim would have been obvious without providing any reason why the achieved result means the previous step would have been obvious. Further, although Petitioner cites to Dr. Reader’s declaration (Ex. 1003 ¶ 233), Dr. Reader’s testimony does not provide any further explanation or reason as to why this aspect of limitation 1[c] would have been obvious.11 Rather, the Petition’s 11 To the extent Petitioner relies upon its discussion of the combined teachings of Lewis and Marusi as set forth at the beginning of Petitioner’s discussion of this ground (see Pet. 54–57), that portion of the Petition does not provide an additional reason why retrieving a list of assets as recited in discussion appears to be exactly the same as Dr. Reader’s testimony on this point.

For example, the statement by user “temperance”—that Petitioner objects to as being relied on for the truth of the matter asserted (Paper 46, 1– 2)—is offered to show that “[t]here was plenty of healthy debate on the boards about the quality of the new version of the codec,” and “many commenters specifically praised the deblocking.” See Ex. 2045 ¶ 46.

Because Petitioner provides adequate support for this second position, we address Patent Owner’s arguments based on this proposed combination.”).

    “ordinary meaning of “bias signal” is “a signal having a steady predetermined level.” Resp. 24; Reply 6. The parties also agree that at least some information signals may be considered “bias signals.” The crux of the parties’ disagreement is which type of information signal. The ’940 patent defines “information signal” as “[t]he signal that contains the information that is to be transmitted. As used herein, it refers to the original baseband signal at the source.” Ex. 1001, 8:48–50 (emphasis added). Thus, the ’940 patent clearly defines “information signal” as “the original baseband signal at the source.” The ’940 patent defines “baseband signal” as: Any generic information signal desired for transmission and/or reception. As used herein, it refers to both the information signal that is generated at a source prior to any transmission (also referred to as the modulating baseband signal), and to the signal that is to be used by the recipient after transmission (also referred to as the demodulated baseband signal). Ex. 1001, 7:41–47. The ’940 patent clearly gives a broad meaning to “baseband signal” such that it encompasses any signal desired for transmission and/or reception, but the definition of “information signal,” as quoted above, does not refer to any baseband signal. Rather, it refers to “the original baseband signal at the source.” Ex. 1001, 8:48–54. By including the terms “original” and “at the source,” the meaning of information signal, as defined by the ’940 patent, is more limited than the definition of a baseband signal. Thus, Petitioner’s contention that the meaning of “information signal,” and, hence, “bias signal” should be expanded to include any “baseband signal” (Reply 4) improperly takes “information signal” out of context. Petitioner’s contention eliminates the terms “original” and “at the source” from the ’940 patent’s definition of “information signal,” without providing any reason why those terms should not be considered.

Rather, it refers to “the original baseband signal at the source.” Ex. 1001, 8:48–54. By including the terms “original” and “at the source,” the meaning of information signal, as defined by the ’940 patent, is more limited than the definition of a baseband signal. Thus, Petitioner’s contention that the meaning of “information signal,” and, hence, “bias signal” should be expanded to include any “baseband signal” (Reply 4) improperly takes “information signal” out of context. Petitioner’s contention eliminates the terms “original” and “at the source” from the ’940 patent’s definition of “information signal,” without providing any reason why those terms should not be considered. Accordingly, we agree with Patent Owner and construe “bias signal” to mean “(1) a signal having a steady, predetermined level or (2) the original baseband signal at the source”; and we construe “reference signal” to mean “the original baseband signal at the source.”6” slip op. at 12

    “decided by the Board.” Resp. 31. Petitioner does not discuss the constructions of these terms in its Reply. See generally Reply. Based on the arguments before us, construing these terms does not appear to resolve a controversy between the parties. Accordingly, we agree with Patent Owner that we need not construe expressly any of these terms for purposes of this Decision.” slip op. at 14

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “4. Level of Ordinary Skill in the Art Petitioner contends that one of ordinary skill in the art as of October 1998 would possess, at a minimum, either (a) a master of science degree in electrical engineering and two or more years of experience in radio frequency circuit design, or (b) a bachelor of science degree in electrical engineering with three or more years of experience with the design and development of RF circuits. Pet. 10 (citing Ex. 1002 ¶¶ 24–29). Petitioner’s argument is supported by Dr. Larson’s testimony. Ex. 1002 ¶¶ 24–29. Patent Owner does not contest Petitioner’s designation of the level of ordinary skill in the art as of the date of the invention. Accordingly, for the purposes of this Decision, we adopt Petitioner’s proposed level of ordinary skill in the art.” slip op. at 18

    “Petitioner’s argument in its Reply is based on its incorrect claim construction of “bias signal” as encompassing any information signal. See, e.g., Reply 7 (asserting that the “bias signal” is met by Dobrovolny’s disclosure because it teaches “an information carrying High Level RF Source for reception”) (citing Ex. 1023, 1:14–17; Ex. 1002 ¶¶ 154, 210). As explained above, “bias signal” is understood to mean “(1) a signal having a steady, predetermined level or (2) the original baseband signal at the source.” See supra Section II.A. Petitioner does not argue, and has not established, that Dobrovolny’s RF Source signal is either at a steady, predetermined level or is the original baseband signal at the source. Thus, Petitioner has not shown that Dobrovolny discloses the “bias signal” recited in claim 21 and the claims that depend therefrom, or the “reference signal” recited in claim 25 and the claims that depend therefrom.8 8 Petitioner does not rely upon Maas or Nardozza as disclosing a “bias signal” or “reference signal.” See Pet. 37–38 (relying only on Dobrovolny), 52–53 (same). Accordingly, Petitioner has not shown, by a preponderance of the evidence, that the combination of Dobrovolny, Maas, and Nardozza would have rendered the subject matter of claims 21, 25, 26, 281, 283–286, 289, 293, 363–366, 369, and 373 obvious to one of ordinary skill in the art at the time of the invention.” slip op. at 20
