“We disagree with Patent Owner and again find Petitioner’s description of the level of ordinary skill in the art sufficient for the reasons explained in the Decision on institution. See Dec. 8–10. As explained before, the formal training required by Petitioner’s description of a POSA includes understanding of both proteins and analytical techniques for studying them. See Dec. 9. Neither Patent Owner, nor its declarant, Dr. Cimas, clearly articulates a competing POSA description at trial, but both suggest more formal training, e.g., a graduate degree, is required. See Resp. 65–66; Ex. 2023 ¶ 8 (agreeing with our observation that the educational backgrounds of the inventors and authors of Cai, Zaccaria, and Hu “suggests that a graduate degree is more typical for a POSA”) (quoting Dec. 9, n. 5). Even if we were to accept that modification, it would not change our findings herein. Nor does it suggest that Dr. Vargas, who holds a Ph.D. in chemistry from Stanford University and has substantial experience with mass spectrometry and other analytical techniques, is unqualified to testify from the perspective of one of ordinary skill in the art. See Ex. 1004 (Vargas CV). Accordingly, our findings and conclusions would be the same, even assuming the perspective of a POSA possessing the higher level of formal training and specific proteomics experience that Patent Owner suggests is appropriate here.5” slip op. at 9

“Ex. 1001, 20:33–39. As Petitioner points out, the first sentence in this passage does not define the term “biological sample,” but rather the term “sample.” Id. According to that sentence, the term “sample” refers to either “a biological sample or a complex biological sample obtained from a subject.” Id. (emphasis added). Patent Owner’s argument assumes, without explanation, that the phrase “obtained from a subject” modifies both instances of “biological sample” in the first sentence. Id. But it need not be read that way. Indeed, that sentence is more naturally read to define “sample” as one of two things––either a “biological sample” or a “complex biological sample” with only the latter being “obtained from a subject.” Id. In addition, the second sentence in the passage above supports Petitioner’s view that the term “biological sample” is not limited to a sample obtained directly from a subject. It provides a broad, non-exhaustive list of “[s]uitable biological samples” that specifically includes the types of biological samples, i.e., “cell lysates,” “systemic blood,” “plasma,” assayed in Petitioner’s cited references. Ex. 1001, 20:36–39. It also lists as an example “processed tissue samples,” which would include samples that have been modified (i.e., “processed”) from the form in which they were originally obtained. Id.; see also Ex. 1001, 20:52–57 (describing tissue processing). Given this broad description, we agree with Petitioner that there is no basis in the cited intrinsic evidence for reading in the “negative limitations” Patent Owner seeks to try to distinguish the particular biological samples assayed in Cai, Hu, and Zaccaria. See Reply 3–4.” slip op. at 12

“We agree with Petitioner. Step 1(a) recites forming coronas around a plurality of particles of “different particle types.” Ex. 1001, 86:53–60. Step 1(b) recites separating a “subset of the plurality of the particles comprising the coronas.” Id. at 86:61–65. As Petitioner correctly observes, as a matter of ordinary English parlance, “there is no requirement whatsoever that the ‘subset’ have all of the same characteristics as the set from which it is separated.” Reply 10. By way of analogy, consider a jar containing a plurality of coins of different coin types, e.g., nickels and dimes. One can separate out a “subset” of that plurality of coins (plural) by removing any two coins from the jar—this is true even if the two coins are both nickels or both dimes. In the same way, nothing in the ordinary meaning of the claim language requires the subset in step 1(b) to include particles with coronas representative of each of the different particle types in step 1(a). Nor has Patent Owner identified any other evidence that supports its attempt to read such a requirement into the claims. See Resp. 16, 18 (citing expert testimony that is not inconsistent with the broader, ordinary meaning of the claim language and, even if it was, would not be a proper basis for limiting the same). For these reasons, we reject Patent Owner’s interpretation of “a subset of the plurality of particles comprising the coronas” in step 1(b) as limited to a subset of each type of particle comprising the coronas formed in step 1(a).” slip op. at 15

“We credit Petitioner’s showing above and agree that Cai discloses a method comprising all of the steps in claim 1. Beginning with step 1(a), Cai discloses contacting two different particle types, i.e., MWCNT and CB, with HeLa cell lysate (i.e., a biological sample) to form protein coronas around those particles. Ex. 1003 ¶¶ 199–206; Ex. 1005, Abstr. (describing MWCNT and CB as distinct “forms of carbon nanoparticles” that bind “vastly different sets of proteins”). Cai’s results show the coronas formed around the MWCNT and CB particles comprise overlapping and distinct proteins as recited in step 1(a). Ex. 1003 ¶¶ 216–222; Ex. 1005, 587 (“a small number of CB-binding proteins also bind to MWCNTs”). A subset of the proteins from the coronas on these particles is then prepared by eluting the bound proteins and analyzing them with SDS-PAGE in a MWCNT and CB “pull-down,” which reads on step 1(b). Ex. 1005, 586 (Fig. 1A–B depicting scheme for “pull-down experiment” and describing other “pull-down experiments” used with SILAC media in Fig. 3), 588 (Fig. 3). Regarding step 1(c), Cai discloses assaying the proteins in those subsets using LC-MS/MS with SILAC encoding to characterize and quantify the relative abundance of the proteins that bind to each type of particle.11 Ex. 1003 ¶¶ 225–229; Ex. 1005, 586–587 (describing “systemic characterization of carbon nanoparticle-protein corona”), 588 (Fig. 3). Cai’s results show “the relative abundance of the MWCNT-binding proteins spread over 8 orders of magnitude” and that “some of the proteins with the highest binding efficiencies” are actually “low abundance proteins” in the lysate, meaning that that Cai’s method selectively enriches such proteins for detection. Ex. 1005, 587. We credit Dr. Vargas’s testimony that these results demonstrate that Cai’s method achieves the “dynamic range” recited in step 1(c). Ex. 1003 ¶¶ 225–229.” slip op. at 23

“We do not credit Dr. Anthony’s testimony, which is based on the arbitrary shading in Figure 7 (see Ex. 1002 ¶ 174), that Schröder teaches or suggests limitation 1[d] because it (1) is inconsistent with Petitioner’s reasoning for limitation 1[c], and (2) it is based on an admitted misreading of the embodiment of Schröder’s Figure 5 (see Ex. 1002 ¶ 175). As to the first item, Dr. Anthony states that “a POSITA would have been motivated to place a battery in a part of the cavity that is far from a PCB holding other electrical components because that configuration allows for better thermal management.” Ex. 1002, para. 175. The problem with this statement is that Petitioner relies on Schröder’s teaching that inlay 12, i.e., the alleged PCB, could include “other electrical components,” such as a battery to support its position that Schröder suggests placing a battery between the ring halves. See, e.g., Pet. Reply 2 (pointing to Dr. Mercier’s depo testimony that inlay 12 with “other components” is inserted between ring halves); id. at 3 (relying on Schröder’s teaching about placing components in depressions on inlay 12). So, Petitioner earlier asserts for the battery limitation 1[c] that Schröder teaches or suggests putting a battery on inlay 12 inside the ring halves, but then for limitation 1[d], Dr. Anthony testifies that a POSITA would place the battery “far” away from the inlay 12 (i.e., the alleged PCB).

“Patent Owner indicates that in the related ITC proceeding involving the ’178 patent, the Administrative Law Judge (ALJ) adopted three constructions agreed-upon by the parties in that proceeding8 and also construed two disputed terms.9 Resp. 26–27 (citing Ex. 2016, 5, 6, 14). Patent Owner agrees with Petitioner, however, that no terms need to be construed to decide the issues raised in the Petition. Id. at 27. We reviewed the constructions adopted by the ITC. Ex. 2016, 5, 6, 14. 8 In the ITC proceeding, the ALJ adopted the parties’ agreed-upon constructions that: (1) the preamble of claim 1 [a finger-worn wearable ring device] is limiting; (2) [positioned/configured to fit] within a “cavity” is [positioned/configured to fit] within a “hollow space”; and (3) [the internal housing component] “coupled with” [the external housing component] is [the internal housing component] “connected with” [the external housing component]. Ex. 2016, 5. 9 In the ITC proceeding, the ALJ construed the claims such that: (1) the internal and external housing components of claims 1, 12, and 17 enclose space and do not necessarily exclude potting material; and (2) “circumferential,” as recited in claims 1, 17, and 18, does not require a closed shape. Ex. 2016, 14, 17. These constructions are not germane to the issues we need to decide to resolve this proceeding. Thus, we agree that no explicit claim construction is necessary for this decision.

“The record supports Patent Owner’s argument that Mestas’s batteries are much too large to fit within a ring form factor, and “Mestas’s batteries, layout, and other components . . . would have to be scaled down 5 to 10 times to be appropriately sized for a finger worn ring.” Resp. 64 (internal quotation marks omitted) (citing Dr. Anthony’s cross-examination testimony at Ex. 2021, 313:12). Moreover, we do not credit Dr. Anthony’s testimony that miniaturization of the battery would have been “trivial to implement.” Ex. 1002 ¶ 242. Dr. Anthony admitted on cross-examination that it would not have been within the level of skill of a person having ordinary skill in the art to design a smaller version of Mestas’s battery, and that such a person would need to procure a battery of the appropriate size and specifications for implementation in a finger-ring from a battery manufacturer. Ex. 2021, 315:9–318:9. Yet Dr. Anthony had not ascertained, for purposes of his testimony, whether there was a battery available in 2013 that was appropriate to fit within the inlay space of the modified version of Schröder’s finger-ring that he and Petitioner allege would have been obvious to one of skill in the art at that time. Id. at 321:5–10. Further, we credit Dr. Mercier’s testimony that Dr. Anthony’s testimony fails to consider the differences in power requirements between Mestas and Schröder or to account for the constraints of such a substantially smaller form factor in Schröder’s finger-ring as compared to Mestas’s wrist device. Ex. 2018 ¶¶ 159–160. Although large curved batteries suitable for use in a wrist band or other larger wearable device, such as shown in Mestas, were known at the time of the ’178 patent, we also have evidence that prior art “finger ring wearables up to the ’178 patent had used ‘coin’ type batteries.” Id. at 66 (citing Ex. 2018 ¶ 161). We credit Dr. Mercier’s testimony that a person having ordinary skill in the art would look to a coin type battery for the necessary power requirements of Schröder’s device. Ex. 2018 ¶ 161. Indeed, this testimony is consistent with the other art of record that consistently shows the use of flat batteries in finger-ring devices, often stacked above and protruding from the general ring shape of the device. See, e.g., Ex. 1005 (Niwa), Figs. 22, 28; Ex. 2025 (Asada ’701 patent), Fig. 4; Ex. 1035 (Rhee), Figs. 7-1, 8-1, 8-2; Ex. 1037 (Asada article), Fig. 9; Ex. 1034 (Asada ’199 patent), Fig. 2; Ex. 1028 (Kimura), Fig. 24; Ex. 2018 ¶¶ 61–70. In fact, Oura’s first-generation ring design, released in 2015, used a Superbowl ring-type design, with the battery and other components mounted on top of the ring. Ex. 2034; Ex. 2018 ¶ 71. Based on these findings, Petitioner has not met its burden to show by a preponderance of the evidence that a person having ordinary skill in the art would have been led to modify Schröder’s finger-ring to place a curved battery between the internal and external housing components in light of the teachings in Mestas. Thus, Petitioner has not met its burden to show by a preponderance of the evidence that dependent claim 3 of the ’178 patent is unpatentable over Schröder and Mestas.” slip op. at 38

“We also adopt the parties’ position that the preamble of claims 1 and 7 is not limiting beyond the term “granule.” Claims 1 and 7 each recite “[a] chemically stable dry flow, low compact, dust free soluble phosphoramidothioate granule consisting of” the set of ingredients recited in body of those claims. Ex. 1001, 7:44–45, 8:19–20. While the wherein clause describing the dimensions of “said granule” relies on “granule” in the preamble for antecedent basis, none of the other preamble language appears to be necessary to breathe life and meaning into the claim, and the claim body recites a structurally complete invention. See Catalina Marketing Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed.

“As discussed above, we agree with Petitioner that Kirchhoff discloses the use of SSL, a protocol that uses data encryption (Ex. 1005, 8:47–49). We also agree with Petitioner that Krtolica discloses the use of HTTP protocols on port 80 (Ex. 1004, 6:23–24), and does so with a goal of maintaining high network security (id. at 1:7–10, 2:33–36). As Kirchhoff discloses, and Dr. Lavian’s testimony supports, one of ordinary skill in the art would have been aware that port 443, rather than port 80, would be used for secure web connections using SSL, which includes the use of encryption, and this would have resulted in enhanced network security. See Ex. 1005, 3:38–41; Ex. 1002 ¶¶ 52, 69, 108. As Dr. Lavian testifies, SSL/TLS was the most widely deployed security protocol in the world and the well-known use of SSL in HTTPS protocol enables secure web-based e-commerce. Ex. 1002 ¶¶ 69, 108; Ex. 1035 ¶ 8; Ex. 1006, 5. And, Krtolica has a stated goal to maintain network security. Ex. 1004, 1:7–10, 2:33–37. We find this evidence provides a sufficient rational underpinning in support of obviousness for combining the teachings of Krtolica and Kirchhoff. See KSR, 550 U.S. at 418. Owner’s arguments that use of encryption in SSL was optional and adding encryption would allegedly undermine network security. Nor do we find persuasive the argument that the Petitioner’s motivation to combine based on efficiency is insufficient, because Petitioner relies on another rationale for the combination of Krtolica and Kirchhoff, that is, enhanced network security, also discussed above. We additionally do not find persuasive Patent Owner’s arguments that combining Krtolica and Kirchhoff would render the system of Krtolica unsatisfactory for its intended purpose because, as Petitioner argues, this assertion is contradicted by the state of the art at the time. See Pet. Reply 9. As discussed above, Dr. Lavian explains that there were known systems having firewalls with SSL traversal at the time of the invention. Ex. 1002 ¶¶ 53, 59–65; Ex. 1035 ¶ 20; Ex. 1014. Moreover, the ’978 patent uses encryption with firewalls using a single-port protocol, and Patent Owner does not direct us to any disclosure in that patent that indicates that the use of encryption with a single-port protocol was inventive in that the system, or that encryption had to be done in a special manner. See Pet. Reply 3 (citing Ex. 1001, Fig. 3 (at 311, 341), Fig. 5 (503, 508)); see also Ex. 1001, 6:4–8.

“testimony from their respective declarants on whether one of ordinary skill in the art would understand “in response to” as requiring “independent of other circuit conditions.” Compare Reply 2–3 (citing Ex. 1016 ¶¶ 18–21, 26–30; Ex. 2003, 43:16–45:1) with PO Resp. 14–15, 17 (citing Ex. 2001 ¶¶ 42, 44–45.) and Sur-Reply 11–12 (citing Ex. 2001 ¶ 45). Patent Owner further directs our attention to a single sentence of deposition testimony in which Petitioner’s declarant Dr. Szepesi appears to agree with Patent Owner’s construction by stating, in the context of claim 9, that “the output signal of this first comparator disables the output pulses driving the gate of that independent of anything else.” PO Resp. 8 (citing Ex. 2003, 44:16– 45:1). Petitioner rebuts Patent Owner’s arguments by identifying additional deposition testimony and statements made in a second declaration offered by Dr. Szepesi opposing Patent Owner’s construction. Reply 2–3 (citing Ex. 1016 ¶¶ 18–21, 26–30; Ex. 2003, 43:16–45:1). For instance, immediately before the statement Patent Owner cites, Dr. Szepesi testified: Q: “So is it your opinion that an output for disabling the pulse generator must disable the pulse generator regardless of the other conditions in the circuit?” . . . A: “I don't understand your question. I said disabling the pulse generator means that the output of the pulse generator which is providing the pulses to the gate of the main switch, those pulses are disabled. That’s what it means in my opinion in this context.” Ex. 2003, 43:24–44:9. And, in his supplemental declaration, Dr. Szepesi states: As a first matter, I opined during my deposition that “an output disabling a pulse generator” means that “the output signal of this first comparator disables the output pulses driving the gate of that independent of anything else.” But, at the time of my deposition I had not done a focused claim construction analysis of the limitation “a first comparator […] having an output for disabling the pulse generator.” This is because I hadn’t anticipated there being a dispute relevant to the validity analysis in view of what I understood as the plain meaning of the language. Despite the quote that Patent Owner relied upon, I believe now that a POSITA would not understand the claim language to require the first comparator to disable the output pulses independent of anything else. This belief is consistent with my responses to the first two of three successive questions in which I was asked about “disabling the pulse generator.” It is my opinion that the operation of the disclosed embodiment requires the presence of other conditions precedent before the first comparator can disable the drive pulses and this requirement is not excluded by the claim language. Ex. 1016 ¶ 18 (emphasis added). Our reviewing court has made clear that extrinsic evidence “is generally of less significance than the intrinsic record” in matters of claim construction. Wi-LAN, Inc. v. Apple Inc., 811 F.3d 455, 462 (Fed. Cir. 2016) (citation omitted). Here, beyond competing declarant testimony, neither party has entered into the record extrinsic evidence, such as dictionary definitions or contemporaneous usage in the art, addressing the scope of “in response to.” Having considered the testimony upon which Patent Owner relies and weighing it against the claim language itself, the Specification’s disclosures set forth above, and the contrary testimony of Petitioner’s declarant, we find on balance that it does not warrant departing from the plain and ordinary meaning of “in response to” as Patent Owner urges. See In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994) (holding that an inventor may define specific terms used to describe invention, but must do so “with reasonable clarity, deliberateness, and precision”) (quoting Intellicall, Inc. v.

“Claim 4 further recites, “a control circuit having an input coupled for receiving the detect signal, wherein the control circuit disables the switched drive control signal in response to the detect signal.” Patent Owner’s sole contention with respect to claim 4 is that “[t]he alleged detect signal in Hwang does not satisfy this limitation” because “unlike the ’221 patent, the alleged ‘control circuit’ does not disable the switched drive control signal ‘in response to the detect signal’ independent of other circuit conditions.” PO Resp. 15–16. As discussed above, we decline to import into claim 4 a requirement that the claimed disabling must occur independent of other circuit conditions. See supra Section III.C.1. Because Patent Owner’s argument relies on a claim construction that we rejected above, we are not persuaded that Hwang fails to meet the limitations of claim 4. Rather, having reviewed the evidence cited by Petitioner, we agree with Petitioner that Hwang discloses the limitations of independent claim 4, arranged as recited in the claim. Petitioner’s analysis, as supported by the Szepesi Declaration, further demonstrates where Petitioner contends each element of dependent claims 5 and 6 is disclosed in Hwang. Pet. 21–24.

Petitioner argues, and we are persuaded, that “Cunningham explains that the ‘most current cumulative reading’ is the current absolute ‘reading’ (i.e., information signal) from the sensor (Ex. 1004, 13:44–46) and that two cumulative readings can be used to ‘interpolate’ and ‘recover’ a missed reading (i.e., a signal from the sensor).” Reply 7 (citing Ex. 1004, 13:44–56; 31:6–27; Pet. 75; Ex. 1002 ¶¶115, 152; Ex. 1046 ¶32).

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.

“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
