“B. Level of Ordinary Skill in the Art Relying on the testimony of Dr. Raghunathan, Petitioner proposes that a person of ordinary skill in the art at the time of the alleged invention of the ’014 patent “would have had at least an M.S. degree in computer science, computer engineering, or electrical engineering (or equivalent experience), and would have three years of experience with computer hardware and software power management design techniques.” Pet. 24 (citing Ex. 1102 ¶¶ 57–58). In our Institution Decision, we adopted Petitioner’s proposal with a modification to the level of education based on Patent Owner’s proposal in its Preliminary Response. Inst. Dec. 7 (citing Prelim. Resp. 5). Specifically, we determined that “a person of ordinary skill in the art would have had at least a B.S. degree in computer science, computer engineering, or electrical engineering (or equivalent experience) and three years of experience with computer hardware and software power management design techniques.” Id. Neither party argues during trial that our definition of the level of ordinary skill in the art was incorrect. See PO Resp. 2–3. See generally Pet. Reply. 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 a person of ordinary skill in the art would have had at least a B.S. degree in computer science, computer engineering, or electrical engineering (or equivalent experience) and three years of experience with computer hardware and software power management design techniques.” slip op. at 8

“Weighing the parties’ arguments and evidence on the complete record now before us, we find Petitioner has not shown that a person of ordinary skill in the art would have understood Takahashi’s “predetermined value” to be an estimated power gain. 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. Accordingly, Petitioner has not shown by a preponderance of the evidence that claim 1 would have been obvious over the teachings of Takahashi.” slip op. at 19

“We focus on one argument we find particularly persuasive—that Hu does not teach using the L2Access:leak ratio to “determin[e] whether to power down” a cache or a portion of a cache, as required by claim 1, even if the L2Access:leak ratio can be considered a relationship between an estimated power gain and an estimated power loss. See PO Resp. 24; PO Sur-reply 16–18. In its Reply, Petitioner alleges that “Hu explicitly discloses using the L2Access:leak ratio to determine when to power down the L1 cache.” Pet. Reply 16 (emphasis added) (citing Ex. 1102 ¶¶ 97–98). Petitioner, however, does not support this proposition by quoting or citing specific language in Hu, relying only on Dr. Raghunathan’s declaration, which provides substantially the same discussion as the Petition. Compare Ex. 1102 ¶¶ 97–98, with Pet. 39–40. 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. Rather, Hu discloses determining values of the normalized cache leakage energy for different decay intervals at four values of the L2Access:leak ratio—5, 10, 20, and 100. 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. Ex. 1104, 175. As Patent Owner correctly asserts, Hu does not describe using the L2Access:leak ratio to determine an appropriate decay interval, nor does Hu describe using the L2Access:leak ratio to determine whether to power down a portion of a cache.

“We agree with Patent Owner that we should not address the patentability of claim 9 in this Decision. See PO Resp. 63–64. Rather, following Federal Circuit case law, we treat claim 9 as if it never existed. See Gunn v. Kopf, 96 F.3d 1419, 1422 (Fed. Cir. 1996) (“A statutory disclaimer under 35 U.S.C. § 253 has the effect of canceling the claims from the patent and the patent is viewed as though the disclaimed claims had never existed in the patent.”). Consistent with other Board decisions in which some, but not all, challenged claims have been disclaimed after institution, we address the patentability only of the remaining claims. See LG Elecs., Inc. v. Wi-LAN Inc., IPR2018-00673, Paper 48 at 3 (PTAB Sept. 5, 2019) (Final Written Decision); Yamaha Golf Car, Paper 63 at 3; Baker Hughes, Paper 74 at 6, 11–12. We also agree with Patent Owner that we should not enter adverse judgment as to claim 9. See PO Sur-reply 26–27. Arthrex, the case relied on by Petitioner, does not mandate a different outcome. By its terms, 37 C.F.R. § 42.73(b)(2) permits disclaimer to be construed as a request for adverse action when there are “no remaining claim[s] in the trial.” That was the situation in Arthrex. 880 F.3d at 1347 (“Arthrex, Inc. disclaimed all claims that were the subject of the petition.”). Here, in contrast, several claims remain in the trial. Furthermore, Arthrex does not support Petitioner’s patent are disclaimed.” Pet. Reply 27. The Arthrex language quoted by Petitioner compares disclaimer of an “entire patent” under § 42.73(b)(1) with disclaimer of “some of the claims” of the patent (i.e., fewer than all claims in the patent but all challenged claims so there are no remaining claims in the trial) under § 42.73(b)(2). 880 F.3d at 1350.

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.

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.

“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.

“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.

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

“radially” in the Petition. In its Reply, Petitioner equates “radially” to “outwardly” and “axially” to “downwardly.” Pet. Reply 7. Patent Owner contends that “axially and radially” would have been understood by a person of ordinary skill in the art “to refer to movement relative the body and oriented relative to the axis of the body.” PO Resp. 19 (citing Ex. 2018 ¶ 82). In particular, Patent Owner contends that “axial” refers to “movement along or parallel to the axis of the body, and that “radial” refers to “the direction perpendicular to the axis of the body.” PO Resp. 20. Patent Owner contends its interpretation is consistent with the Specification of the ’099 patent and is supported by both its expert, Mr. Underwood, and Petitioner’s expert, Mr. Shale. Id. at 18–21 (citations omitted). For example, Mr. Shale testified that “‘[r]adially’ basically means left to right within the tubular body,” and “‘axially’ means up and down within the tubular body.” Ex. 2021, 189:5–7. Patent Owner further notes that Figures 4, 5, 11, and 12 of the ’099 patent illustrate arms 520 moving axially and radially relative to body 510. PO Resp. 20. In its Reply, Petitioner argues that “[c]ontrary to Patent Owner’s assertion, claim 1 of the ’099 [p]atent does not require that the body 10 be the frame of reference for the axial and radial movement.” Pet. Reply 13 n.3. Petitioner, however, cites no persuasive evidence to counter Patent Owner’s proposed construction. Contrary to Petitioner’s assertion, Mr. Shale agreed that “radially” corresponds to “outward from the body,” and that “axially” corresponds to “up and down of the body.” Ex. 2021 190:4–19. Consistent with Mr. Shale’s testimony, Petitioner’s analysis purports to show that Myers discloses movement of moveable arms (slips 30) “both axially and radially relative to the body 10 [of Myers].” Pet. 19– 20. Petitioner is not alleging movement of the slips of Myers relative to a feature other than the body of Myers or in some other frame of reference. See Tr. 10:1–21. Thus, based on the evidence discussed above, we determine “translates axially and radially,” as recited in claim 1, means “moves parallel to and perpendicular to the body” and does not encompass movement consisting of only rotation about a pivot point. slip op. at 9

The lower ends of the slips 30 are coupled for movement longitudinally with one another by being connected to a slip ring 35 having generally T-shaped slots 36 therein receiving companion T-shaped heads 37 on the lower portions of the slips. Thus, the slips 30 move longitudinally jointly with the slip ring 35, although they are still permitted to move radially or laterally inwardly and outwardly of the slip ring, upon relative longitudinal movement between the slips 30 and expander 26. Ex. 1004, 3:2–17. In this passage, the movement of the slips includes “longitudinal movement,” which we understand generally corresponds to a vertical direction, as opposed to lateral movement in a horizontal direction. However, the movement is described relative to expander 26, not relative to body 10. See Pet. 13 (using “lateral” consistent with the horizontal extent and “longitudinal” consistent with the vertical extent). Thus, this passage also does not explain expressly whether slips 30 move axially relative to the body during deployment.” slip op. at 18

Petitioner relies on Bostock as disclosing a spring for biasing. Id. As to the limitations of claim 1 from which claims 4, 33, and 34 depend, including the requirement of “one moveable arm translates axially and radially,” Petitioner relies only on the contentions it set forth under its anticipation analysis with respect to claim 1. Because Petitioner does not rely on Bostock to teach the recited feature “one moveable arm translates axially and radially,” does not argue the feature would have been obvious over the combination, and, for the reasons provided above, has not shown by a preponderance of the evidence that Myers teaches the feature, Petitioner has not shown by a preponderance of the evidence that claims 4, 33, and 34 of the ’099 patent would have been obvious over Myers and Bostock.” slip op. at 25

“Mr. Shale expresses the opinion that “slips 30 move both axially and radially relative to the body 10, along ‘generally T-shaped slots 36’ that are linear and angled relative to the axial direction,” we find that testimony to be conclusory and entitled to little weight, in part because this testimony does not account for the upward movement of setting sleeve 40. See Ex. 1010 ¶ 53 (quoting Ex. 1004, 3:11); see also In re Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1368 (Fed. Cir. 2004) (“[T]he Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations.”); 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Accordingly, we find Mr. Shale’s declaration fails to provide persuasive support for Petitioner’s contention that Myers discloses “one moveable arm translates axially and radially,” as required by claim 1, beyond what Myers, itself, discloses. We find more persuasive Mr. Underwood’s testimony, on behalf of Patent Owner, that Myers fails to disclose axial movement of slips 30. Ex. 2018 ¶¶ 90–107. According to Mr. Underwood: slots [36 of Myers] are shown as angled relative to the slip ring 35. However, though the slips may move downward (axially) relative to the slip ring 35 as the slips move outward (radially), the slip ring 35 at the same time moves upward (axially) relative to the body. As such, the angle of the slots 36 within the slip ring 35 is not, itself, indicative of the overall movement of the slips. Id. ¶ 91. Mr. Underwood further reasons that “as the slip ring moves upwardly, the movement of the slips relative to the body in the axial direction is zero due to the slips sliding downward in the slots 36 relative to the slip ring 35 in equal proportion.” Id. ¶ 94. Mr. Underwood also” slip op. at 20

“We agree with Patent Owner that we need not expressly construe the term “adapter.” We reiterate the following from our Institution Decision: The term “adapter” appears in each claim of the ’691 patent. Neither party contends that the specification or prosecution history contains a lexicographic definition of the term, and neither party asserts that the specification or prosecution history contains a disclaimer of any portion of the plain and ordinary meaning of the term. From our review of the record, the structure and location of the adapter recited in the claims is provided by other claim language describing that (1) the adapter is located external to the fryer, (2) the sensor is disposed in the adapter, (3) the adapter is installed between two portions of the return pipe or drain pipe, and (4) the adapter has two opposite ends wherein one of the two ends is connected to one of the two portions of either the return pipe or the drain pipe and the other end is connected to the other portion of pipe.3 Inst.

“Differences Between the Prior Art and the Claims; Motivation to Modify We instituted Petitioner’s challenge of these claims, and those that depend therefrom, based on Petitioner’s position that Kauffman disclosed most of the elements of the independent claims with the exception of a sensor capable of measuring an electrical property that is indicative of total polar materials. See, e.g., Inst. Dec. 31. Thus, the theory of obviousness, as discussed above, relies upon substituting Iwaguchi’s sensor for Kauffman’s analyzer. See id. at 31 (“Petitioner provides a second argument that relies upon a modification to Kauffman’s system, in which Iwaguchi’s sensor is employed instead of Kauffman’s analyzer. Because Petitioner provides adequate support for this second position, we address Patent Owner’s arguments based on this proposed combination.”). Petitioner confirmed at the oral argument that its Petition proposed a theory in which Iwaguchi’s sensor is simply swapped for that of Kauffman’s and did not present a more general theory as to modifying Kauffman’s sensor per the teachings of Iwaguchi: JUDGE WEINSCHENK: Did you include both of those alternative theories in your petition or is that something that you’re – you’ve come up with now in the reply? MR. VAIDYA: It’s something that we -- again, in the reply, we wanted to make it very clear that we aren’t going on a 102 basis and we are -- and what -- I think what -- we did have that alternate in the reply, so the alternate -- and I can point to paragraphs if that helps. And so, the idea is again primarily we’re going with the idea of swapping sensors, but that it would be possible to modify the sensor in Kauffman. JUDGE GERSTENBLITH: Because in the petition, it was a swap of the sensors. MR. VAIDYA: That’s right. JUDGE GERSTENBLITH: And that’s what we instituted -- MR. VAIDYA: That’s correct. JUDGE GERSTENBLITH: -- based on. MR. VAIDYA: That’s correct. Tr. 13:21–14:12.

“We do not agree with Petitioner that Avrahami’s pointing to and identifying seed points, constitutes movement of a first visual marker. Rather, as Patent Owner explains, “prior to the user’s click, the seed point does not exist, and thus there is nothing to move.” See PO Resp. 18 (citing 2008 ¶ 56). Avrahami’s characterization of the already-placed seed point as the “initial 2D seed point” supports Patent Owner’s position. See Ex. 1003, 44.

“First, we give no credit to Dr. Chao’s opinion in this regard because it is not supported by Spinney. Specifically, we give no weight to Dr. Chao’s opinion that “Spinney makes clear that the CAM lookup and the hashing function (i.e., the forwarding lookup) take place at the same time.” Ex. 1002 ¶ 53. Instead, we find that the parallel operations in Spinney are confined to (1) applying the hash function to the 48-bit address and (2) performing a CAM lookup of the same 48-bit address. For example, Spinney discloses in Figure 8 that incoming address field 85 is subjected to hash function 86 to produce another 48-bit value. See id. at Fig. 8, 15:21−24; 16:16−19 (“The 48-bit destination address 61 from an incoming packet is simultaneously subjected to the hash function 86 and a CAM match” (emphasis added)), 16:44−46 (“this compare in the CAM is done in parallel with the hash function” (emphasis added)). The application of the hash function and the performance of the hash lookup are two different operations that produce different results. The hash function application produces a hashed 48-bit value, while the hash lookup results in pointing to an entry in the translation table that includes the gigaheader information, for processing the packet. See id. at Fig. 8 (identifying hash function 86 applied to input address 85, resulting in hashed address 89); 15:60−63.
