      “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. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)); see also 37 C.F.R. § 42.104(b) (requiring a petition for inter partes review to identify how the challenged claim is to be construed and where each element of the claim is found in the prior art patents or printed publications relied upon). This burden of persuasion never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). A patent claim is unpatentable under 35 U.S.C. § 103(a) when the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) when in evidence, objective evidence of nonobviousness, i.e., secondary considerations.4 Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). Additionally, the obviousness inquiry typically requires an analysis of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (requiring “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)). Petitioner cannot satisfy its burden of proving obviousness by employing “mere conclusory statements,” but “must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016).” slip op. at 10

      “We agree with Patent Owner. First, the construction of the phrase “at least one of [A] the display, [B] the audio and [C] the hardware (HW) action” is conjunctive in light of the language of the claims and the specification of the ’887 patent. As such, Petitioner has the burden, but fails to show all three (3) components to be reproduced at Yun’s mobile device, including: [A] the display, [B] the audio and [C] the hardware (HW) action by the HW component of the mobile device. Second, as Patent Owner observes, and we agree, “Petitioner ignores the requirement for ‘the hardware (HW) action’ entirely” and does not even mention any “hardware (HW) action.” Prelim.

Fintiv, Inc., IPR2020-00019, Paper 11 (Mar. 20, 2020) (precedential) (“Fintiv”). In support of Factor 6, Petitioner argues for the first time that Overton (not Yun or Lu) is allegedly teaching “the hardware (HW) action” aspect of the claims. Prelim.

Petitioner’s declarant, Mr. Crevelt, further testifies that Okita’s “[r]ewards programs are a routine feature of games because players are encouraged to play more to accumulate points or other pseudo-values to exchange for prizes or other items . . . [t]he virtual money conversion functionality would have opened up more game play options and more items to purchase.” Ex. 1003 ¶ 187.

Dr. Henze testifies that, in his opinion, the level of ordinary skill is as stated by Petitioner. Id. at 31. He also states that “[s]uch experience could be obtained through research and study in a graduate program or through comparable exposure through industry employment, and additional years of experience could substitute for the advanced-level degree.” Id.

      “Petitioner asserts that nine terms are “mean-plus-function claim terms.” Pet. 4–10. As required by our rule, (37 C.F.R. § 104(b)(3)), for each of the mean-plus-function claim terms, Petitioner identifies the function as well as the specific portions of the ’181 patent’s specification that describe the corresponding structures. Id. Patent Owner does not comment on Petitioner’s proposed means-plus- function claim constructions. See generally Prelim. Resp.

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

      “At this stage of the proceeding, we disagree with Patent Owner’s construction that requires “distinguishing among different types of targets” in order to obtain “target specific feature information” because claim 1 does not recite such a limitation. Instead, we agree with Petitioner that the plain and ordinary meaning “requires target specific feature information for distinguishing specific targets from background clutter, not other targets.” Reply 2. We note that claim 1 does not require distinguishing between different targets nor does it include any recitation directed to a particular “learning process (e.g., Generalized Hebbian Analysis),” as Patent Owner implies. Sur-reply 2. We also agree with Petitioner that the doctrine of claim differentiation supports Petitioner’s construction because claim 7 adds a limitation not present in claim 1 by reciting “distinguish[ing] two target classes or a plurality of target classes from one another.” Ex. 1001, 12:28–30. Moreover, the Specification contemplates selecting target specific feature information to distinguish specific targets from background clutter without distinguishing among different types of targets because the Specification explains that the inventor tested the preferred classification system using target objects “of several different types” such that “the preferred embodiment needed to find receptive fields common to all types.” Id. at 9:41–48 (emphasis added). Accordingly, we find Petitioner’s proposed construction of “target specific feature information to distinguish specific targets from background clutter” as having its plain and ordinary meaning to be reasonable and consistent with the intrinsic record. Thus, we adopt it for purposes of this Decision. On this limited record, and at this early stage of the proceeding, the Board has not made a final determination on the construction of “target specific feature information to distinguish specific targets from background clutter.” We encourage the parties to further develop this argument (such as to the extent it would differentiate the prior art) and their positions at trial.” slip op. at 15

      “4. Conclusion for Claim 1 After reviewing Petitioner’s assertions with respect to claim 1 and the supporting evidence (as summarized above), we determine that Petitioner has shown, sufficiently at this stage, that Barnard teaches all the limitations of claim 1. See Pet. 12–34. We therefore determine that Petitioner is reasonably likely to prevail in showing that claim 1 is unpatentable under § 103 as obvious over Barnard. We have also reviewed the arguments and evidence of record addressing claims 2, 3, 6, and 7 in Ground 1, and similarly find that for purposes of institution, Petitioner has demonstrated a reasonable likelihood that Barnard would have rendered these claims obvious. See Pet. 34–39. On this basis, we institute inter partes review of all challenged claims on all grounds in the Petition. See SAS Inst. Inc., 584 U.S. at 368; 37 C.F.R. § 42.108(a).” slip op. at 35

    • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

      “On this record, we find Petitioner has shown sufficiently that Barnard teaches using “target specific feature information” to distinguish specific targets from background clutter, as required by claim 1. See Pet. 16–32. As set forth above, on the current record we do not construe the claim limitation reciting “target specific feature information to distinguish specific targets from background clutter” to require “distinguishing among different types of targets based on tailored feature selection,” as Patent Owner suggests. Prelim. Resp. 27. Instead, we agree with Petitioner that the plain and ordinary meaning of the claim limitation simply “requires target specific feature information for distinguishing specific targets from background clutter, not other targets.” Reply 2; Section II.C.1. Based on the current record, and consistent with this understanding, we find Petitioner has shown sufficiently that Barnard uses various calculated data statistics to select a set of features and an associated target detection threshold in order to distinguish specific targets from background clutter. See Pet. 16–17 (citing Ex.1003 ¶¶ 65–68 (citing to Ex. 1005, 2:30–36, 5:36–49, 6:62–68)). Petitioner explains that Barnard “discard[s] or exclude[es] features that have a statistical distribution width exceeding a predetermined amount,” and as such, “Barnard selects features (i.e., the remaining features not excluded) that are used to distinguish specific targets from background clutter.” Id. at 17 (citing Ex.1005, 2:28–39; Ex. 1003 ¶ 66). Patent Owner argues that “[a]t best, Barnard generically applies the same set of features to all potential targets, and then filters out those deemed unreliable due to statistical variance,” and relying on the Declaration testimony of Dr. Majumder, contends that “[t]his is not the same as selecting features based on their discriminative power for specific target classes, as required by the claims.” Prelim. Resp. 21 (citing Ex. 2007 ¶ 71); see also id. at 25 (“The reference makes no distinction between different types of targets and does not describe using different feature sets or decision boundaries tailored to particular target classes.”), 30 (“Petitioner’s attempt to equate Barnard’s one size-fits-all filtering with the claim’s target-specific discrimination reflects a misunderstanding of both the reference and the invention.”). However, on the current record, Patent Owner’s argument is unpersuasive at least because it is based on an overly restrictive construction of the limitation “target specific feature information to distinguish specific targets from background clutter.” As discussed above, claim 1 does not require distinguishing between different targets or between specific target classes. See Section II.C.1. Although Patent Owner argues that “there is no mention of ‘target” slip op. at 31

      “and 4) does not address Petitioner’s first two arguments and evidence, which, on this record, appear to show that Bucknell’s prioritized queue length is based on buffered data in either, or both, of a first and second iteration. Therefore, at this stage of the proceeding, we need not reach Patent Owner’s assertions as to the third alternative argument and evidence Petitioner provides, namely the combination of examples 2), 3), and 4). For completeness, however, we acknowledge that Bucknell does not expressly combine examples 2), 3), and 4), mainly because example 4) only refers back to example 2). However, we note that from a plain reading of Bucknell’s written description it may not be a significant leap to understand that the disclosed combination of examples 2) and 4), with first and second portions 90 and 95 populated in reverse order as taught in example 4), that this combination could be subsequently modified by example 3) to provide a “second iteration . . . based on buffered data.” Ex. 1006 ¶¶ 26–27. In other words, on the current record it is not clear why “the unused resource” of Bucknell’s second portion 95 cannot also “be made available,” to the first portion 90 if the order was simply reversed per the combination of examples 2) and 4). 3. Conclusion as to Claim 1 In summary, we find Petitioner’s arguments and evidence sufficient to show a reasonable likelihood that claim 1 is unpatentable over Eckert in view of Bucknell and Lohr-1. On the current record, we find that Bucknell discloses “a first iteration” based on receiving the priority values for logical channels associated with the MAC-d flows. Ex. 1006 ¶ 26. And, as discussed above, Bucknell’s described “priorities,” are plural, just like the claimed “received parameters.” Ex. 1001, 14:11; Ex. 1006 ¶ 26. In on a priority.” See Ex. 1001, 13:57–14:16. As to the issue of whether the Petition provides sufficient explanation or motivation to combine Bucknell’s examples 2), 3), and 4), which is an alternative argument to Petitioner’s other mappings for limitation [1.9] which we find sufficient for institution, we leave this alternative mapping issue for development at trial. See Pet. 55 (Petitioner explaining that “Bucknell describes additional ways that limitation [1.9] is disclosed, based on the teachings of examples 2 and 4 (discussed previously) in view of example 3.”).” slip op. at 27

    • Prior constructionPrior construction adoptedDecided for petitioner

      “Petitioner points out that in IPR2022-01127 the Board “preliminarily determined that a subset of the plurality of radio bearers” means “less than all of the plurality of radio bearers.” Pet 12 (citing Ex. 1019, 18–19). Petitioner explains that, in the present proceeding, it has applied “the prior art in accordance with that construction; however, in view of the asserted grounds, no claim term requires express construction to find the Challenged Claims unpatentable.” Id. (citing Nidec 868 F.3d 1017). Patent Owner neither disputes the prior construction of “a subset of radio bearers,” nor offers additional constructions. To the extent necessary, and in accordance with our prior determination, we construe “a subset of the plurality of radio bearers” to mean “less than all of the plurality of radio bearers.” At this early stage of the proceeding, no claim terms are disputed and we need not construe any other terms for purposes of institution.” slip op. at 13
