    “Petitioner, supported by the testimony of Dr. Holberg, argues that a person of ordinary skill in the art (“POSITA”) “would [have] at least a Master’s degree in Electrical Engineering or equivalent field, including studies in the area of analog circuitry; or at least a Bachelor’s degree in Electrical Engineering and at least two years of experience working on analog circuitry design.” Pet. 23 (citing Ex. 1003 ¶¶ 54–56). Neither Patent Owner nor its declarant, Dr. Moon, dispute or offer an alternative level or skill in the art at this time. See generally PO Resp., see also Ex. 2001 ¶ 13 (Dr. Moon stating that Petitioner’s asserted level of ordinary skill in the art is “reasonable”). On the full record now before us, the parties do not dispute the proposed level of ordinary skill in the art. Petitioner’s proposed level of ordinary skill is consistent with our review and understanding of the technology and descriptions in the ’075 patent and the prior art references that disclose electronic circuits including analog-to-digital converters using modulation feedback signals and charge injection in MOS transistor circuits to account for differential non-linearity. For purposes of this Decision, we rely on Petitioner’s proposed level of ordinary skill in the art.” slip op. at 8

    “The term “perturbation” is, however, inextricably linked to “dither” in the context of the ’075 patent. It is clear from multiple descriptions in the ’075 patent that perturbation of the sampled voltage introduces dither into the analog to digital converter. See Ex. 1001, 7:62–8:4 (The ’075 patent states that “selective switching of capacitors within the sub capacitor array can be used to perturb the voltage that was sampled onto the main capacitor array during the sampling phase and hence introduce a positive or negative dither into the analog to digital converter.”); see also id. at 2:7–11 (The ’075 patent describing dithering where “[m]ultiple conversions of substantially the same input value can result in the input value being assigned different ‘bins’ within the conversion process as a result of different perturbations being applied at each individual sampling point.”).”) On the full record now before us, we agree with both parties to an extent. Considering Petitioner’s position, we find that dither has a broader meaning than perturbation in the context of the ’075 patent and, based on Dr. Holberg’s testimony, that a person of ordinary skill in the art would have understood perturbation as “a small change in movement, quality, or behavior of something, especially an unusual change.” Reply 5; Ex. 1003 ¶ 81. With respect to Patent Owner’s arguments and evidence, we do not agree that perturbation is simply random noise, but we find persuasive Patent Owner’s declarant, Dr. Moon, and his testimony that the ’075 patent uses this term “to describe the disturbance or agitation of the charge stored on the capacitor array, in a manner that introduces dither” into the analog to digital converter. PO Resp. 19–20. In sum, perturbation means “a small change in movement, quality, or behavior of something, especially an unusual change, and describes the disturbance or agitation of the charge stored on the capacitor array that introduces dither into the analog to digital converter.”” slip op. at 13

    “Ex. 1003 ¶ 83. This explanation potentially explains how one of skill in art could apply a perturbation, but does not explain why a person of ordinary skill in the art would do so after sampling or why such a person would find the result of applying perturbation after sampling predictable. At best, Dr. Holberg’s testimony describes that a person of ordinary skill in the art could change the offset capacitance code B0, B1 during the course of sampling the input voltage onto the capacitor array and after sampling. And, that this would achieve the claimed perturbation “after . . . sampling.” Id. This explanation, however, describes a result of manipulating Confalonieri’s CATT capacitance circuit and does not articulate sufficient reasoning as to why a person of ordinary skill in the art would have done so. Petitioner’s arguments and Dr. Holberg’s testimony are mostly conclusory and unsupported on this point. First, Petitioner points out what Confalonieri does not expressly disclose, namely “whether the offset perturbation is provided before or after sampling.” Pet. 28 (citing Ex. 1012, 6:28–46; 6:51–55). Second, Dr. Holberg testifies that a perturbation could be effected by “establish[ing] a first code to the capacitance CATT (i.e., switched capacitor digital to analog converter) during sampling, and then apply a different code to the capacitance CATT after the sampling phase has been completed.” Ex. 1003 ¶ 83. However, beyond this statement Dr. Holberg provides no persuasive supporting or evidentiary basis for reaching this conclusion, and no citation to Confalonieri for any disclosure of providing a first offset capacitance code during sampling, then another different capacitance code after sampling. On this point, Petitioner argues that Confalonieri states that “[t]he additional shunt capacitance in the lower array can be used as a component for further functions, such as an offset compensation.” Pet. 26 (citing Ex. 1012, 5:58–60) (emphasis added). In pointing out this language, Petitioner is insinuating that “further functions” includes perturbation. See id. at 28 (Petitioner states that “[t]he provision of offset in Confalonieri discloses the perturbation as claimed.”). We are not persuaded that this is an appropriate reading of Confalonieri. Prior to the language referenced by Petitioner, Confalonieri discusses that “the shunt capacitance operates as a voltage attenuator, so that it is easy to limit the dynamics at the node NSL by a proper selection of this capacitance.” Ex. 1002, 5:46–48. The following paragraph then explains that “[t]he additional shunt capacitance in the lower array can be used as a component for further functions, such as an offset compensation.” Id. at 5:56–58. A plain reading of Confalonieri, in context, is more reasonably understood as indicating that (1) the shunt capacitance CATT “provides a strong improvement of the converter linearity, while the operation speed is as high as the operation speed of the prior art basic design,” (2) “power consumption is also as low as in that prior art design,” and (3) the shunt capacitance can be used for “further functions, such as an offset compensation.” Id. at 5:53–57. Nowhere does Confalonieri indicate that shunt capacitance CATT is considered for perturbation or dithering, or to provide offset during or after the input voltage sample is sampled onto the upper and lower array. Indeed, this interpretation of Confalonieri by Petitioner never references any testimonial support from Dr. Holberg, nor do we find related support in Dr. Holberg’s testimony related to such an interpretation of Confalonieri and claim element 16[c]. See, e.g., Ex. 1003 ¶¶ 79–84. In this way, Petitioner and Dr. Holberg essentially rely on the absence” slip op. at 24

    “Petitioner’s reasoning “that dither as provided in Hiller could be provided in the system of Confalonieri instead of, or in addition to, offset in order to provide the known desirable and well known performance benefits of dither” arguably asserts a desired result, e.g., a more accurate circuit, but does not explain why a person of ordinary skill in the art would have replaced or supplemented offset compensation of an input voltage with dither. Id. This is particularly true where we have persuasive evidence that offset is a different technique and is applied for a different reason and result compared to dither. See Ex. 2017 ¶ 91 (Patent Owner’s declarant, Dr. Moon testifying that “Confalonieri discloses the provision of offset but does not disclose the provision of dither.”); Ex. 2001 ¶ 26 (Dr. Moon testifying that “instead of reducing errors, dither redistributes or smears out the errors.”); Ex. 2018, 74:9–10 (Petitioner’s declarant, Dr. Holberg testifying that Confalonieri “does not mention dither in—in his patent.”). Indeed Dr. Moon provides an explanation of how Confalonieri designed its circuit for improved linearity, as was the state of the art in 2005, not with dither, but by “a circuit design that allows all the capacitors (especially the coupling capacitor) to be sized in integer multiples of a unit capacitance, which improves capacitor matching.” Ex. 2001 ¶ 23 (citing Ex. 1012, 4:36–5:8). Confalonieri expressly discloses any problems of accuracy and linearity related with the dimensioning of the coupling capacitor Cs is solved simply by the addition of a shunt capacitor CATT in the lower array. Since all the capacitors of the converter can be designed as integer numbers of a unit capacitance, all the layout tools normally used for obtaining optimum matching of integrated components can be used. Ex. 1012, 4:65–5:4. Dr. Moon explains further that using capacitance matching for “addressing root causes of DNL directly reduces the DNL errors, dither as described in ’075 patent randomizes the errors. That is[], instead of reducing errors, dither redistributes or smears out the errors. Thus, how dither improves DNL is different than how improving capacitor matching improves DNL.” Ex. 2001 ¶ 26. It is not explained sufficiently by Petitioner, where linearity was already addressed by Confalonieri’s circuit design itself, even if one of ordinary skill in the art could have potentially added dither in an ADC using shunt capacitance CATT instead of, or in addition to compensating for offset, why a skilled artisan would have looked to Hiller’s teaching of dither. Considering the complete record now before us, we are not persuaded” slip op. at 31

    “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.

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.

    “In its Reply, Petitioner contends that “[c]ontrary to [Patent Owner’s] claim that Lewis does not teach a list and that there was no reason to modify Lewis’ system ([PO Resp.] 30–32), the Petition and Dr. Reader clearly explain why lists and database operations would have been obvious to a [person of ordinary skill in the art].” Pet.

Petitioner reiterates the position asserted in the Petition—that it would have been obvious to retrieve a list of assets because Lewis teaches that a dynamic manifest file contains a list of URLs to container files containing content.

These exhibits are cited in the Hanson Declaration only as evidence of industry praise, i.e., to support testimony based on his personal knowledge. See Ex. 2045 ¶ 51. And although Mr. Hanson quotes statements from these exhibits in his declaration, their relevance lies in that they allegedly reflect praise for DivX’s deblocking method. 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.

Patent Owner, with the support of Dr. Wolfe’s credible testimony, persuasively argues that Takahashi’s “predetermined value” is a previous value of the cache-miss rate. Petitioner, on the other hand, does not point to anything in Takahashi that describes the “predetermined value” as an estimated power gain, nor does Petitioner cite any testimony from Dr. Raghunathan in support of its position other than a portion of his declaration that is substantially the same as the discussion in the Petition. See Pet. 33–34 (citing Ex. 1102 ¶ 80); see also Ex. 1102 ¶¶ 72– 80 (testimony substantially the same as pages 29–34 of the Petition). Without any suggestion in Takahashi that the “predetermined value” relates to an estimated power gain, Takahashi’s stated goal of reducing power consumption is not sufficient to show that Takahashi’s “predetermined value” is representative of an estimated power gain. For these reasons, we find that Petitioner has not established that Takahashi teaches or suggests an estimated power gain or determining whether to power down a portion of a device component in response to a relationship between an estimated power gain and an estimated power loss, as recited in independent claim 1.

We agree with Patent Owner that the portion of Hu cited in the Petition and Dr. Raghunathan’s declaration does not teach using the L2Access:leak ratio to determine whether to power down the L1 cache, as Petitioner contends. See PO Sur-reply 16–18; Pet. 39–41; Ex. 1102 ¶¶ 97– 99.

Ex. 1104, 175–76; see PO Sur-reply 17. Hu uses these assumed values of the L2Access:leak ratio as inputs to generate simulation data, not to determine whether to power down a cache or portion of a cache. Ex. 1104, 175, see PO Resp. 24; PO Sur-Reply 15–16. Petitioner argues that Hu teaches that the higher the L2Access:leak ratio, the longer the system should wait before powering down the cache. Pet. 39–41; Pet. Reply 16–17. Hu, however, does not expressly compare the effect of different L2Access:leak ratios other than to state that when the L2Access:leak ratio is 100, a small decay interval is detrimental to performance and power.

    “person of ordinary skill in the art at the time of the invention of the ’207 patent “would have had at least a[n] M.S. degree in electrical engineering and would have at least two years of experience with circuit design.” Pet. 17 (citing Ex. 1002 ¶ 32). In our Institution Decision, we found Petitioner’s proposal consistent with the level of ordinary skill in the art reflected by the asserted prior art and adopted Petitioner’s position, which Patent Owner did not oppose in the Preliminary Response. Inst. Dec. 14 (citing Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001)). Neither Patent Owner, in its Response, nor Dr. Ipek, in his declaration, proposes a level of ordinary skill in the art. Dr. Ipek, however, states that “[f]or purposes of the subject IPR proceedings, I have been asked to employ [Petitioner’s proposed] standard of a person of ordinary skill, but I do not offer the opinion that it is the correct standard.” Ex. 2011 ¶ 19. Nothing in the full record persuades us that our preliminary finding as to the level of ordinary skill in the art was incorrect. Accordingly, because our preliminary determination is consistent with the level of ordinary skill in the art reflected by the prior art of record, we maintain and reaffirm that one least an M.S. degree in electrical engineering and at least two years of experience with circuit design.

    “the complete record developed during this inter partes review, we again conclude that the “third voltage reference” must be separate from the “second voltage reference.” We begin with the language of claim 1, which recites a first voltage reference, a second voltage reference, and a third voltage reference as separate elements.7 “Where a claim lists elements separately, ‘the clear implication of the claim language’ is that those elements are ‘distinct component[s]’ of the patented invention.” Becton, Dickinson & Co. v. Tyco Healthcare Group, LP, 616 F.3d 1249, 1254 (Fed. Cir. 2010) (citation omitted). The terms “first,” “second,” and “third” are terms used to distinguish separate elements of a claim. See Gillette Co. v. Energizer Holdings, Inc., 405 F.3d 1367, 1373 (Fed. Cir. 2005); see also 3M Innovative Props. Co. v. Avery Dennison Corp., 350 F.3d 1365, 1373 (Fed. Cir. 2005) (“The use of the terms ‘first’ and ‘second’ is a common patent-law convention to distinguish between repeated instances of an element or limitation.”). Although Gillette and 3M address whether such terms impose a numerical or serial limitation, they nevertheless support Patent Owner’s position that enumerated elements typically are not construed to be the same element. See Sur-reply 11–12. Other cases cited by Patent Owner also support its position. See id. at 12 (citing Regents of the Univ. of Minn. v. AGA Med. Corp., 717 F.3d 929, 935–39 (Fed. Cir. 2013) (construing “first” and “second” disks as separate and discrete disks); Engel Indus., Inc. v. Lockformer Co., 96 F.3d 1398, 1405) (Fed. Cir. 1996)” slip op. at 21

    “ordinary skill in the art would have sought to reduce power consumption in Takahashi to address the well-known problem of current leakage, and that providing a separate voltage reference for transistor 223 in Takahashi’s Figure 15 (i.e., a third voltage reference) would have achieved that goal. Pet. 34–35 (citing Ex. 1002 ¶ 88). But the only evidence Petitioner relies on for adding the proposed third voltage reference is the testimony of Dr. Stojanovic. Id. (citing Ex. 1002 ¶ 88). Without any additional supporting evidence, Dr. Stojanovic’s testimony is insufficient to supply the missing “third voltage reference,” which is a key limitation of claim 1. See K/S Himpp v.

Lee, 136 S. Ct. 2131, 2144–46 (2016). Only terms that are in controversy need to be construed, and these need be construed only to the extent necessary to resolve the controversy. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999). In our Institution Decision, we construed several claim terms recited in claims 1–17. Inst. Dec. 13–20. Patent Owner requests cancellation of claims 1–16 and we did not institute inter partes review of claim 17. Thus, none of the claim terms we construed previously are at issue in the trial. Additionally, Patent Owner’s Response and Sur-Reply and Petitioner’s Reply do not request that we construe any additional claim terms. Accordingly, we need not construe expressly any claim terms to resolve the controversy before us. See Vivid Techs., 200 F.3d at 803.” slip op. at 15

    “how or why an ordinarily skilled artisan would have been led to combine Weichselbaum and Nesso in the manner claimed. On that point, the Petition rests on bare opinion testimony that is not tethered to any disclosure in the prior art or other objective proof. Pet. 32 (citing Ex. 1002 ¶¶ 168–170). We are mindful that a reason to combine prior art may exist “in the content of the public prior art, in the nature of the problem addressed by the invention, or even in the knowledge of one of ordinary skill in the art.” Princeton Biochemicals Inc. v. Beckman Coulter Inc., 411 F.3d 1332, 1338-39 (Fed. Cir. 2005). But when we turn to the opinion testimony that undergirds Petitioner’s argument on the reasons to combine, we find no objective proof and inadequate reasoning. Id. Ultimately, Petitioner presents two very weak reasons based on unstated and unexplained factual assumptions in support of its view that one of ordinary skill in the art would have been prompted to modify Weichselbaum. Additionally, as explained above, Petitioner takes conflicting positions as to how Nesso’s second chute would be incorporated in Weichselbaum’s device and the record remains unclear as to the precise structure resulting from Petitioner’s combination. Accordingly, Petitioner fails to provide sufficient clarity regarding the specific modifications to Weichselbaum, fails to provide a sufficient reason with rational underpinning as to why and how one of ordinary skill in the art would have modified Weichselbaum in light of Nesso, and appears, on this record, to engage in an impermissible exercise of hindsight reconstruction to make out a reason to combine the applied references in the manner claimed. Further, in light of the full trial record, including Patent Owner’s evidence of secondary considerations discussed below, we are persuaded that the bare opinions set forth in the Visser Declaration (Ex. 1002 ¶¶ 168–170) are entitled to little weight. See Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for” opinion testimony “going to factual determinations” may be of little probative value in validity determination.”).” slip op. at 36

    “specific product and that product ‘is the invention disclosed and claimed in the patent.’” WBIP, 829 F.3d at 1329 (citation omitted). The presumption is rebuttable, but “a patent challenger cannot successfully rebut the presumption with argument alone—it must present evidence.” Id. (citation omitted). Patent Owner has shown that the asserted objective evidence, discussed further below, is tied to a specific product and that product “is the invention disclosed and claimed in the patent.” Id. (quoting J.T. Eaton & Co. v. Atl. Paste & Glue Co., 106 F.3d 1563, 1571 (Fed. Cir. 1997)). “This showing––that the specific products are embodiments of the claimed invention and that the proffered objective evidence relates to these products—is sufficient to establish the presumption of nexus for the objective considerations at issue in this case.” Id. at 1330. It is, therefore, Petitioner’s burden to rebut that presumption. Id. at 1329 (“a patent challenger cannot successfully rebut the presumption with argument alone— it must present evidence”); see Tr. 46:20–47:8 (Petitioner agreeing that nexus is presumed and that Petitioner has the burden to overcome the presumption.). Petitioner does not rebut the presumption of nexus. First, Petitioner’s entire argument is phrased as challenging whether Patent Owner satisfied its burden of establishing nexus, as opposed to whether Petitioner rebuts the presumption of nexus. Pet. Reply 20–21 (“It is Patent Owner’s burden to establish a nexus.”) (citing CaptionCall LLC v. Ultratec Inc., IPR2013- 00540, Paper 78 at 50 (PTAB Mar. 3, 2015)). Second, Petitioner points to other factors, including higher prices and increased advertising, referred to in Campbell’s annual reports that contributed to increased soup sales. Pet. Reply 21–22. There is no dispute that other factors also contributed to the increase in soup sales. But, there is also no dispute that Campbell’s own statements, through its Annual Reports and Mr. Finnel’s interview, tie increased soup sales expressly to Gamon’s display racks. Additionally, Campbell’s internal presentation describes Gamon’s IQ Maximizer as “Breakthrough Gravity Feed Shelving” and attributes the following to the display racks based on the results of its study: • +13.6% volume lift for Corporate Brand • +10% volume lift for Condensed Segment • +9.3% volume lift for Campbell’s Condensed • +5.5% volume lift for Wet Soup Category • Encourages purchase of additional varieties • Billboard effect improves branding: 210% larger • Positive labor impact due to elimination of shelf conditioning Ex. 2032, 4. Although other factors had some degree of impact on commercial success,29 we determine that Patent Owner has established that an appreciable amount of Campbell’s increased commercial success of soup during the relevant time period is attributable to the display rack covered by claim 27 of the ’111 patent. Accordingly, Gamon’s sales to Campbell of about $31 million from 2002–2009 as well as a portion of the increased sales of Campbell’s soup using Gamon’s display racks provide a strong showing of commercial success of the commercial embodiment of claim 27 of the ’111 patent.” slip op. at 61
