    “Patent Owner did not dispute that the combined teachings of Kumada and Debladis ’120 disclose each limitation of claim 1. Patent Owner, however, did dispute Petitioner’s proposed reasons for combining Kumada and Debladis ’120, and argues that Debladis ’120 is not analogous art. PO Resp. 36–61. The Federal Circuit stated that substantial evidence only supports the conclusion that a POSA would have been motivated to combine the teachings of Kumada and Debladis ’120. The factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan. Nothing more is required to establish a motivation to combine. Given that Willis has conceded that the combination of Kumada and Debladis ’120 disclose all the limitations in claim 1, we reverse the Board’s patentability determination as to that claim and vacate the Board’s judgment as to the remaining claims of the ’037 patent. Everstar II, 2025 WL 1501940, 4 (internal citations omitted). The Federal Circuit further noted Patent Owner’s secondary considerations arguments as to claim 1 and stated [t]he cited evidence consists only of a temporal connection between the introduction of Willis’s invention and the UL 588 standards, and deposition testimony of a single witness who seemingly disclaimed any connection between the two. This is not sufficient to rescue a claim as to secondary considerations. Id. at 4, n. 5 (internal citations omitted).

    “We find the ’212 Patent is directed to data for a particular user (see, e.g., ’212 Patent, Abstract). This conclusion is supported by the Specification. Indeed, all discussion in the ’212 patent is directed to a pedometer for use by and relying on data obtained from an individual user. Thus, the Specification suggests that the term “calibration” should be construed as a process that correlates a user’s stride rate and stride length. The Oral hearing confirms this conclusion. In the Oral Hearing, Petitioner’s counsel, Mr. Doshi, responded to a request to identify the calibration and the plurality of calibrations as follows: JUDGE STEPHENS: So what are you pointing at in the 212 patent as being [a] calibration and the plurality of calibrations? MR. DOSHI: That’s in column 5. So at column 5 it says that after a proper warm up the user completes a sample run or walk on the track at normal pace, et cetera, et cetera. So it's saying that here’s S1 and following completion of the first run, so here it’s saying you’re doing different walks at different speeds . . .where you're having the user walk at different walking speeds and measuring their step size as you do that (Trans. 21:1–10; see also Tr. 19:4–7) JUDGE ZADO: Okay. And then so taking that further then, I understand your argument to be that in the 212 patent the runner for the first sample S1 will run at one pace and that’s, according to Petitioner, that's one calibration and then the runner will run at a second pace for the S2 sample and that’s the second calibration, and then the runner will run at a third pace and then that's the S3 sample and then that's a third calibration? Is that Petitioner's argument? MR. DOSHI: Yes 13 (Tr. 22:4–11). Therefore, based on Petitioner’s statements at the Oral Hearing, the term “calibration” should be construed as the process of taking a sample that correlates step rate and step length for an individual.” slip op. at 13

The technology of the ‘212 Patent implicates other fields, such as Sports Medicine, Exercise Science, and Physiology. I believe that a bachelor’s degree in one of these fields, or a similar field, with at least two years of practical experience working with pedometers and/or health or fitness trackers or sensors, or an advanced degree in one of these areas, could qualify one as a PHOSITA in this case (Ex. 2001 ¶ 26).

    “Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved (In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004)). Here, Petitioner has persuaded us that Levi is from the same field of endeavor as the ’212 Patent –– pedometers that count the number of steps taken to calculate distance traveled (see Pet. 20). Specifically, although Levi adds a navigation feature, Levi is directed to a pedometer that, in pertinent part, adjusts step size according to step frequency in order to estimate distance traveled by a user (Levi, 6:6–43). Levi states “[t]he present invention for a ground speed/distance sensor is an improvement over a common hiker’s pedometer” and “[t]he present invention analyzes the frequency of a user’s footsteps to aid in the detection of future footsteps, and further to aid in determining the size of footsteps taken by the user” (Levi, Abstract, 2:57–60, 2:65–67). Similarly, the ’212 Patent is directed to a pedometer and specifically, a pedometer that calculates actual stride lengths of a user based on relative stride rates (’212 Patent, Abstract). Thus, both the ’212 Patent and Levi are from the same field of endeavor –– pedometers or devices that include or rely on pedometers. Furthermore, both Levi and the ’212 Patent are pertinent to the particular problem with which the inventor is involved –– accurate distance identification. 44 Patent Owner additionally argues “[t]he different problems addressed” slip op. at 44

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “A holding of obviousness can be based on a showing that “there was an apparent reason to combine the known elements in the fashion claimed” (KSR Int’l v. Teleflex, Inc., 550 U.S. 398, 418 (2007)). Such a showing requires some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness. . . . [H]owever, the analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ. (id. at 418 (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)) (internal quotation marks omitted)). As admitted by Patent Owner, an ordinarily skilled artisan would have known a user’s stride length could vary with stride rate at the time of invention (see PO Resp. 52). As noted by Petitioner, Levi discloses using a dynamic step size algorithm that “improve[s] the accuracy of distance 49 measurements of a human footstep sensor” (Pet. Reply 25 (citing Levi, 6:17–21)). We further credit Mr. Blackadar’s testimony that an ordinarily skilled artisan would have been motivated to improve Jimenez using Levi’s dynamic step size algorithm, to improve the calculated distances (Ex. 1005 ¶¶ 92). Indeed, we find that an ordinarily skilled artisan would have been motivated to combine the teachings of Jimenez and Levi to “monitor [ ] the distance traveled more accurately than prior pedometers that calculated distance based on average stride length” (Pet. 31 (citing Ex. 1005 ¶ 90), 32 (citing Ex. 1005 ¶ 92)). In particular, we find that, given it was known a user’s stride length could vary with stride rate, as admitted by Patent Owner (PO Resp. 52), an ordinarily skilled artisan would have been motivated to implement a data processor that accounted for this relationship, such as that described in Levi (Pet. 32–33 (citing Ex. 1005 ¶¶ 93–94)).” slip op. at 49

Additionally, the passage in the December 1998 IEEE article that cites to Rabinovich refers to an algorithm in Rabinovich for optimizing access to data in order to increase performance. Id.

According to Dr. Ratner, “[t]he metric cnt(s,xs) measures the total number of times in that window that replica xs has been served to a client computer.” Ex. 1005 ¶ 253. As Patent Owner points out, Rabinovich teaches replicating object xs if the ratio of cnt(s,xs) over aff(xs) is greater than m, i.e., a non-zero value. PO Resp. 34; Ex. 1006, 12, Fig. 4. In view of this, we agree with Patent Owner that if cnt(s,xs) has a value of zero, meaning that object x has not been served to any client computer, then the ratio of cnt(s,xs) to aff(xs) will be zero, i.e., less than m, and Rabinovich will not carry out its replication step. This means that Rabinovich will not replicate object xs until xs has been accessed by a client computer at least once, such that the access count for xs is greater than zero. In this regard, we agree with Patent Owner that Rabinovich object xs is not “sen[t], from the at least one data storage device to the another data storage device . . . independently of an access of the at least one client computer” because Rabinovich teaches explicitly that object xs is not sent unless there has been at least one access from the client computer.

    “pieces” Claim 1 recites “each file including a plurality of individual pieces, the pieces containing parts of the files.” Ex. 1002, 25:67–26:1. The other independent claims recite limitations commensurate in scope. Neither party proposes explicitly a construction of the term “piece.” Petitioner argues that “files are inherently composed of pieces in the form of bits that make up bytes, the bytes themselves being pieces of the file.” Pet. 32. Patent Owner argues that construing “piece” to cover “bits and bytes” of a file “would read out the ‘pieces’ limitation from the claim entirely” (PO Resp. at 29–30) and that “one of ordinary skill in the art would not read the ‘pieces’ limitation of the claim to include bits and bytes” (id. at 30). The claims themselves define “piece” by requiring that a “file” have a “plurality of individual pieces,” but do not establish a lower bound—i.e., a minimum number of bits or bytes—to qualify as a “piece.” Patent Owner identifies no support in the ’680 patent for its contention that “piece” or “pieces” excludes a byte or bytes of a file, relying instead solely on the testimony of Dr. Paul S. Jacobs. Id. (citing Ex. 2006 ¶¶ 38, 39). We are not persuaded by Dr. Jacobs’s conclusory testimony. Because “piece” and “pieces” are limited by the claims only to being a subset of a file and because a byte or collection of bytes of a file is a subset of that file, we are persuaded that the broadest reasonable interpretation of “piece” and “pieces” in light of the Specification of the ’680 patent encompasses a byte or bytes. slip op. at 7

In addition, the specification of the ’150 patent does not define explicitly the term “selectively electrically coupling.” Therefore, as in IPR2014-00882 and IPR2014-01011, we refer to its ordinary and customary meaning, as would be understood by one of ordinary skill in the art in the context of the entire disclosure. Translogic Tech., 504 F.3d at 1257. A technical dictionary, the IEEE Dictionary,4 defines “electrical coupling” as “[e]lectrical charges in conductors of a disturbed circuit formed by electrical induction.” Ex. 3001. The IEEE Dictionary explains that “[s]ince the ratio of a conductor’s electrostatic charge to the potential difference between conductors (required to maintain that charge) is the general definition of capacitance, electrical coupling is also called capacitive coupling.” Id.

We further note that the applied prior art reflects the appropriate level of skill at the time of the claimed invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). D.

    “To testify as an expert under Federal Rule of Evidence 702, a person need not be a person of ordinary skill in the art, but rather must be “qualified in the pertinent art.” Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1363–64 (Fed. Cir. 2008); see SEB S.A. v. Montgomery Ward & Co., 594 F.3d 1360, 1372–73 (Fed. Cir. 2010) (upholding a district court’s ruling to allow an expert to provide testimony at trial because the expert “had sufficient relevant technical expertise” and the expert’s “knowledge, skill, experience, training [and] education . . . [wa]s likely to assist the trier of fact to understand the evidence”); Mytee Prods., Inc. v. Harris Research, Inc., 439 F. App’x 882, 886–87 (Fed. Cir. 2011) (non-precedential) (upholding admission of the testimony of an expert who “had experience relevant to the field of the invention,” despite admission that he was not a person of ordinary skill in the art). As noted above, Dr. Jagannathan has designed and implemented hardware virtual memory caches, and researched theoretical performance measures of various cache coherency protocols, and has experience in the design of memory systems. We find that, although Dr. Jagannathan may be less experienced than Dr. Sechen in the area of memory module design, he is nonetheless qualified sufficiently to testify about memory systems and memory modules.

  • ExcludeMotion to exclude, deniedDenied

    “We have reviewed the parties’ contentions on this issue, and exercise our discretion to determine that Petitioner’s Reply and the Jagannathan Supplemental Declaration will not be excluded. We find that, although they may be “inartfully” drafted, the first Jagannathan declaration and Petition sufficiently outlined Petitioner’s position on the function of the chip select signal, namely, that the chip select signal was not itself the logic signal enabling operation of bit-switches. We further find that Petitioner’s Reply and the Supplemental Jagannathan Declaration did not present an entirely new rationale of unpatentability based on Takeda, JEDEC, and Connolly. Cf. Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369–70 (Fed. Cir. 2016) (affirming Board’s exclusion of reply brief and declaration that changed unpatentability theory to “an entirely new rationale”). Moreover, there is no dispute that Patent Owner was aware of Petitioner’s position by no later than the Jagannathan deposition, which preceded Patent Owner’s Response by ten days. Patent Owner could have addressed Petitioner’s chip select signal contention, procedurally or substantively, in its Response, but chose to raise the issue only after Petitioner filed its Reply and Supplemental Jagannathan Declaration. Accordingly, Patent Owner had notice of Petitioner’s position and an opportunity to refute that position in its Response.” slip op. at 24

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “The difference in the opinions of the two experts is that Dr. Sechen believes a person of ordinary skill in the art would have an additional four years of experience, education, or a combination of the two, beyond that proposed by Dr. Alpert. See Ex. 1009 ¶ 7. According to Dr. Alpert, the difference in the proposed levels of ordinary skill in the art is not material to any dispute over claim construction or patentability in this inter partes review. Id. We accord greater weight to Dr. Alpert’s opinion as to the level of ordinary skill in the art because he has experience in both teaching students and working with engineers in the industry, while Dr. Sechen’s experience is primarily in teaching. Compare Ex. 1007 ¶¶ 7, 21 with Ex. 2012 ¶¶ 3, 5. Moreover, based on our review of the ’434 patent and the types of problems and solutions described in the ’434 patent and cited prior art, we agree with Dr. Alpert’s opinion on the level of ordinary skill. Accordingly, we find that a person of ordinary skill in the art at the time of the ’434 patent would have a Bachelor’s degree in electrical engineering, computer engineering, or in a related field and at least one year of work experience relating to memory systems, and would be familiar with the design of memory devices, memory modules, and BIST.” slip op. at 10

    “The above disclosure uses the term “operable independently” to describe the data handlers as being discrete and functioning without being physically or logically connected to each other. Based on our review of the ’434 patent, the specification and claim 27 both use the term “operable independently” in the same manner, i.e., to describe a feature of the data handler that is distinct from its data generation feature. We agree with Petitioner, therefore, that when interpreted in the context of the ’434 patent in its entirety, the claim term “operable independently” “merely means that each data handler can operate without influence or control by any of the other data handlers.” Reply 5. The ’434 patent specification uses the term “operable independently” in accordance with its plain and ordinary meaning, and we find no basis for applying the narrower construction advanced by Patent Owner to any of the challenged claims. Accordingly, we interpret “operable independently” as “operable without influence or control by another.” See Cuozzo, 793 F.3d at 1278–79.” slip op. at 19

    “Based on the above description in Averbuj, we agree with Patent Owner that Averbuj describes memory interfaces (the alleged data handlers) that are configured to produce address and control signals, and that Averbuj describes producing address and control signals in certain circumstances, e.g., when Averbuj’s sequencer (the alleged control module) specifies writing data in a particular pattern that requires transformation to conform to a particular configuration of a memory module. See PO Resp. 33. We also agree with Petitioner, however, that Averbuj’s memory interfaces are further configured to apply to the memory modules the same address and control signals received from, and produced by, the sequencers for testing (see Reply 15), e.g., when the sequencer sends signals that can be applied, without modification or transformation (see Ex. 1003 ¶ 56), directly to a memory module irrespective of its physical configuration. Thus, Petitioner has shown, by a preponderance of the evidence, that Averbuj’s sequencer meets the limitation of “a control module configured to generate address and control signals for testing the memory devices” as recited in challenged independent claims 1, 20, and 29 of the ’434 patent.” slip op. at 41

    “As discussed in Section IV.B.2.e., a petition must include “[a] full statement of the reasons for the relief requested, including a detailed explanation of the significance of the evidence including material facts, and the governing law, rules, and precedent” (37 C.F.R. § 42.22(a)(2)), and “[a] reply may only respond to arguments raised in the corresponding . . . patent owner response” (37 C.F.R. § 42.23(b)). We agree with Patent Owner that the Reply does more than merely respond to or rebut arguments made in Patent Owner’s Response; rather, it sets forth a theory that was not presented clearly in the Petition. Patent Owner’s position is supported by the fact that Dr. Sechen, whose skill level is at least (and appears to exceed) that of the ordinary artisan, apparently was unable to envision how Huang and Averbuj could be combined. Further, Dr. Alpert’s second declaration includes, at a minimum, opinions as to the understanding of the ordinary artisan with respect to the teachings of Huang and Averbuj that were not presented in his first declaration. In our judgment, consideration by the Board of the above-noted arguments in the Reply and evidence presented in Dr. Alpert’s second declaration in support thereof would be improper under 37 CFR § 42.23 and unfair to Patent Owner. We have, however, reviewed and considered the arguments in the Petition and evidence therein, and are in agreement with Patent Owner that Petitioner has not provided adequate explanation or evidence to support its contention that one of ordinary skill in the art would have had a reasonable expectation of success in combining Huang and Averbuj. Accordingly, Petitioner has not met its burden to show, by a preponderance of the evidence, that claims 7–12, 17, 18, 20–25, 27, 28, and 30–35 would have been unpatentable over Huang and Averbuj.” slip op. at 59
