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

      “image capture device” refers to an imaging-based barcode reader and not a laser-based barcode scanner because we are persuaded that claim language and Specification support that interpretation and also because Patent Owner persuasively shows that a person of ordinary skill in the art would have understood the term as such. Claim 1 recites an “image capture device configured to capture an image.” Ex. 1001, 16:24–25. The plain meaning of the claim term requires that the image be captured, not just scanned. The claim further requires “generating an output based on the information embedded in the image,” requiring that information is retrieved from the captured image. Id. at 16:32–33. A device that does not capture an image is not an “image capture device” under the plain language of the claim. A laser-based barcode scanner employs light reflected from a laser beam to “generate an electrical signal that corresponds to the bars and spaces in the barcode being scanned.” See Ex. 2029 ¶¶ 42–43 (explaining in detail how laser-based barcode self-emitting a laser light across a code to be scanned, with a sensor tuned to capture the reflected light from the laser.”). It simply does not capture an image. slip op. at 14

      “Based on our review of the complete record, we determine that Petitioner’s stated level of ordinary skill in the art is reasonable because it is consistent with the evidence of record, including the asserted prior art. The field of the ’167 patent “relates generally to secure transactions, and more specifically, to methods and devices for providing secure identification, verification, and authorization using a portable secure device.” Ex. 1001, 1:8–11. The ’167 patent seeks “to provide methods and devices that are capable of providing secure transactions in a more efficient manner.” Id. at 3:11–13. Accordingly, we adopt Petitioner’s definition. We note, however, that our patentability analysis would be the same under Patent Owner’s definition.” slip op. at 11

      “We agree with Patent Owner that Wang fails to disclose limitation 1[a]. Wang discloses a portable electronic authorization device (PEAD) that can be used as a self-checkout terminal. Ex. 1004 ¶ 115. In this context, Wang discloses By entering the UPC code or barcode using keypad on the PEAD or scanning in the UPC code or barcode using the input device built into the PEAD such as a barcode scanner or OCR reader, the PEAD can generate the receipt with the list of item prices through the wireless network and Internet by querying the item price using the barcode as the index for price lookup table which is Stored in a Server System. Id. (emphasis added). As discussed above (Section III.C.1), we are persuaded by Patent Owner’s arguments that the claimed “image capture device” refers to an imaging-based device and not a laser-based barcode scanner. Petitioner does not contend that Wang’s disclosure of the barcode scanner necessarily refers to an imaging-based device, but argues that Wang’s disclosure is sufficient because “both imaging-based barcode scanners and laser-based barcode scanners constitute image capture devices.” Reply 11. In light of our claim construction above, we disagree.” slip op. at 27

Drummond Drummond is a patent titled “Automated Banking Machine System and Method,” and “relates to an automated banking machine apparatus and system that are capable of use in a wide area network, and which provides a user with a remote electronic receipt or other record related to a transaction performed at the machine.” Ex. 1008, code (54), ¶ 2. Drummond discloses that its automated banking machine, may “initiate the sending of a non-paper transaction receipt to the customer,” “[t]he receipt may be sent using a wide area network, such as the Internet,” and “[t]he receipt may be an electronic receipt, for example a receipt in the form of an e-mail message.” Id. ¶ 247. 2. Claims 1, 4, 5, 7, 12, 17, 23, 26, 27, 29, 34, and 43 For this obviousness ground, Petitioner relies on the same arguments and evidence as its Ground 1a (anticipation by Wang), discussed above, for the majority of claim limitations. See Pet. 33–43. Importantly, Petitioner relies solely on Wang as teaching independent claim limitations [1a], [23a], and [43b] relating to an image capture device and embedded information. Pet. 36, 41, 43. Accordingly, for the reasons discussed above with respect to Ground 1a, Petitioner has not established by a preponderance of the evidence, that the subject matter of claims 1, 4, 5, 7, 12, 17, 23, 26, 27, 29, 34, and 43 would have been obvious to one of ordinary skill in the art over the combination of Wang and Drummond.” slip op. at 31

Reply 2 (citing 01119-Petition, 26–33, substantially identical to Pet. 32– 40). However, again, the Petition does not explain an alternative theory in which Chaudhri supplements Ahn’s menu functionality to move that menu onto the screen, as opposed to teaching visual cues provided by gradual changes of the display during a gesture or the visual cue that an unlock image may provide during the unlock gesture. See Pet. 14–18 (describing Chaudhri teaching “visual differentiation” or “transitioning an optical intensity” between a user-interface object and the background, based on, e.g., transparency), 35–40 (same). In Reply, Petitioner adds evidence to attempt to support its contention that the combination teaches a menu following a user’s finger during a dragging gesture, involving references to Chaudhri’s discussion of a visual cue, further discussing Chaudhri’s unlock image. Ex. 1005 ¶¶ 54, 62, 74–79, Figs. 5A-5C (cited at Pet. Reply 4–5). With respect to these citations and arguments, even if they had been timely presented in the Petition, we agree with Patent Owner that they do not articulate a modification of Ahn with Chaudhri or a motivation to combine. PO Sur-reply 6. Additionally, we agree that these embodiments of Chaudhri are distinct from the cited portions of Chaudhri discussed with respect to this theory in the Petition, which relate not to the movement of displayed graphics, but to variations of optical intensity and visual cues. Id. at 6–7. We evaluate the Petition’s arguments in light of Petitioner’s statement in Reply that they require a teaching regarding “menus . . . following a user’s finger as the user performs the dragging gesture.” Pet. Reply 2. To the extent that the Petition shows that the combination of Ahn and Chaudhri would show visual changes as the user performs a dragging gesture, these do not relate to the movement of a menu, but rather to other optical effects. Thus, as we do not find that the Petition supports an Ahn-Chaudhri combination in which a menu follows a user’s finger as the user performs the dragging gesture to open the menu, as Petitioner argues, we determine that Petitioner has not shown limitation 2.d of claim 2 taught or suggested by the combination of Ahn and Chaudhri according to this theory.” slip op. at 31

      “Petitioner argues that “even under [this] interpretation of Ahn, the only difference between Ahn and the claims is whether the animation occurs in direct correspondence with a user’s dragging gesture or after the dragging gesture is complete – a straightforward design choice if ever there was one.” Pet. Reply 3–4 (citing Ex. 1024, 99:16–108:20; Ex. 1023 ¶ 12). However, as Patent Owner argues (PO Sur-reply 7–8) this argument is presented in Reply and is an improper shift of theory from the Petition. Nevertheless, were we to consider it, we would not find it compelling; Dr. Terveen’s cited testimony repeats this bare statement and is not supported by any evidence or additional explanation.

      “As used herein, “impedance measurement at millisecond time resolution” refers to the ability to perform a series of at least two consecutive impedance measurements within milliseconds of one another for each and every well of the system where each well is associated with an electrode array for impedance measurement. In each instance the time between two consecutive impedance measurements are less than 300 milliseconds from one another. Id. at 10:8–15. There does not appear to be any dispute as to the definitional nature of the first sentence in the passage above. That is, the parties agree that millisecond time resolution should be construed to mean: “the time between two consecutive impedance measurements for each and every well being evaluated in the claimed apparatus or system.” PO Resp. 15 (proposing construction); Pet.

      “Ex. 1003 ¶ 179. But Dr. Kim does not cite to any additional supporting evidence or provide any technical reasoning to support his statements. The notion that one can reduce the time between measurements by, e.g., reducing the number of frequencies measured, has intuitive appeal and appears mathematically correct. However, the absence of technical reasoning and supporting evidence diminishes the persuasiveness of Dr. Kim’s testimony that the POSA would made such modifications to reduce the time between measurements. Dr. Kim does provide some technical reasoning in connection with his discussion of eliminating all reference channels as a way to get the time resolution down to the levels required by, e.g., claim 14, which recites a millisecond time resolution of “less than 5 milliseconds.” See e.g., Ex. 1003 ¶ 172 (“A POSA seeking to study biological cell phenomena occurring on the order of a few milliseconds would have recognized that after measuring the reference network channels at the start, the reference network channels would not need measured again for some time, e.g., because temperature and other drift factors do not change appreciably on a millisecond time scale.”). However, even if we were to credit this testimony, Dr. Kim still lacks support and reasoning for the selection of the other parameters in his noreference-channel calculations. See, e.g., id. ¶ 173 (positing, but not providing technical reasoning for using, a no-reference-channel impedance system with 16 wells, a single 10kHz measurement frequency, and 16 daughter boards that measure simultaneously rather than sequentially).” slip op. at 29

      “be improper hindsight in Petitioner’s position. Petitioner and Dr. Anthony assume that a POSITA would position the battery between Schröder’s ring halves and implement Mestas’s curved battery because it “allows a larger battery to conform to a ring’s circular shape without stressing the battery or ring housing.” Pet. 60, 64–65; Ex. 1002 ¶¶ 337, 351–354. That position, however, ignores alternative designs that are at least equally supported by Schröder’s disclosure (see Ex. 1007, Fig. 3), but would not result in a ring configured as recited in the challenged claims. Petitioner attempts to downplay this concern by characterizing the modification of Schröder’s ring to include Mestas’s curved battery as an obvious “matter of choice” in design. See Reply 10–11 (citing Ex. 1079 ¶¶ 71–77). We disagree. As explained above, the record supports Patent Owner’s argument that Mestas’s batteries are much too large to fit within a ring form factor because they are “5 to 10 times” the size that would be required for a finger ring. PO Resp. 27 (quoting Ex. 2021, 313:12). Petitioner argues that it “does not propose bodily incorporating Mestas’s battery into Schröder’s ring,” which on the surface is correct. See Reply 10. But this does not help Petitioner meet its burden because its actual obviousness theory that “a POSITA would have found it trivial to implement Mestas’s teachings into a ring like Schröder’s ‘finger-ring’” is not persuasive. See Pet. 60 (citing Ex. 1002 ¶ 338). For the same reasons explained in Section II.D.1 above in our analysis of Ground 1, Dr. Mestas’s teaching of a curved battery (Ex. 1002 ¶ 338) in the much smaller form factor of Schröder’s ring is not credible. See Ex. 2021, 315:9–318:9 (acknowledging that it would have been beyond the level of ordinary skill to miniaturize Mestas’s battery, but that a POSITA could try to procure one); 321:5–10 (conceding that he did not try to ascertain whether such a battery was available in the relevant time frame). Instead, we credit Dr. Mercier’s testimony that Petitioner’s proposed modification would have presented intractable practical challenges. Ex. 2018 ¶¶ 228, 230–240 (describing various aspects of battery design that Dr. Anthony did not consider). As before, Dr. Mercier’s testimony is further supported by evidence showing a consistent pattern of flat battery use in prior art finger-ring devices. See, e.g., Ex. 1005 (Niwa), Figs. 22, 29; 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 ¶¶ 57–67. In sum, Petitioner’s showing for limitation 1[c] is deficient in multiple respects. First, Petitioner assumes that an ordinarily-skilled artisan would have been motivated to implement Mestas’s curved battery in the much smaller interior space occupied by Schröder’s inlay 12 without sufficiently considering the feasibility of that modification or alternative designs suggested by Schröder. Second, even if we accept Petitioner’s purported rationale for the combination (which we do not because we find it that it is predicated on improper hindsight), Petitioner has not shown that an ordinarily-skilled artisan would have had a reasonable expectation of successfully implementing the proposed modification.” slip op. at 46

Ex. 2018 ¶¶ 359–360; see also id. ¶¶ 322–346 (pictures depicting wedding band design of the Oura Ring Gen. 3 Horizon and Gen. 4 products); Ex. 2019 ¶¶ 47–49 (“[Patent Owner’s] decision to highlight the ring form factor indicates this feature’s importance to the marketplace success of the Oura Ring.”). We disagree with Petitioner’s assertion that the Oura Ring Application and/or Oura Membership are essential, unclaimed features such that a presumption of nexus is not appropriate. The Oura Application functions in conjunction with the Oura Ring to form a “complete solution” 9 Patent Owner and Dr. Mercier only compare these products to claim 1. Patent Owner has not demonstrated a nexus to independent claim 38. ¶¶ 20–21. The Oura Application cannot receive or display any information absent the Oura Ring’s ability to collect the information from the user. Id. Even though the Oura Application may provide additional unclaimed functionality, such as displaying activity, sleep, and readiness scores based on the data collected by the Oura ring that allow “a user to take advantage of the ring’s offerings,” this functionality is secondary to the ring’s ability to collect that data, without which, the Oura Application would serve no purpose. See Ex. 2019 ¶ 21; Ex. 2024, 93:22–95:22. As the Federal Circuit has explained, “there is rarely a perfect correspondence between the claimed invention and the product.” Fox Factory, 944 F.3d at 1374. Here, we find that on the spectrum of “unclaimed features,” the Oura Ring Application is closer to the “insignificant features” end because, while it allows the user to access and interpret data tracked by their Oura Ring, it does not materially impact the functionality of the Oura Ring or its structure.10 See Teva 8 F.4th at 1361 (explaining that “like the coextensiveness requirement itself, the concept of unclaimed features is best viewed as part of a spectrum”).” slip op. at 27

      “In sum, we find that there is a sufficient nexus between Patent Owner’s results and the challenged claims and that those results are reasonably commensurate with the same. Accordingly, for all of reasons explained above, the unexpected results Patent Owner relies upon are probative of non-obviousness. E. Conclusion for Ground 1 Weighing the record as a whole in view of the findings and analysis above as well as our findings and analysis relating to Petitioner’s prima facie showing in the Decision, we conclude that Petitioner has not met its burden to show that claim 1 would have been obvious over Currie and Li. The evidence suggesting that it would have been obvious to make the Glu3 substitution because it is a conservative substitution (see Dec. 20–38 (§ III.E.ii)) is substantially outweighed by Patent Owner’s comparatively strong evidence demonstrating unexpected results relating to improved interconversion stability, potency, and binding affinity from the Glu3 substitution. See Millennium Pharms., Inc. v. Sandoz Inc., 862 F.3d 1356, 1368 (Fed. Cir. 2017) (“Evidence of objective indicia [such as unexpected results] ‘can be the most probative evidence of nonobviousness in the record,’ and . . . enable[s] ‘the court to avert the trap of hindsight.’”) (quoting Leo Pharm. Prods., Ltd. v. Rea, 726 F.3d 1346, 1358 (Fed. Cir. 2013). Indeed, the interconversion and potency categories of Patent Owner’s unexpected results showing are particularly strong such that even without the additional results in Liu, we would still reach the same ultimate conclusion on obviousness. Accordingly, Petitioner has not shown by a preponderance of the evidence that claim 1 is unpatentable.” slip op. at 56

The statements in the letter were not made under oath, nor is there evidence that Patent Owner was ever able to question the author of that letter or anyone else with personal knowledge of the statements therein.

See Dec. 61–72. Petitioner asserts that the American Peptide letter is admissible under the residual hearsay exception in FRE 807. MTE Opp. 3–5. We disagree. The American Peptide letter was submitted by the EPO opponent specifically for the purpose of opposing a foreign counterpart to the ’786 patent. We see no reason to distinguish it from the other materials previously excluded as hearsay in the Currie submission. Petitioner’s assertion that it contains sufficient guarantees of trustworthiness because it was “provided by a neutral third-party” (American Peptide) and “an individual having first- hand knowledge, [American Peptide Company’s] VP of sales and marketing” is speculation. See id. at 3–4. Based on the record before us, Patent Owner has never been afforded an opportunity to examine anyone regarding the statements in this letter or even confirm that it is, in fact, a letter from the American Peptide Company. The mere fact that it was submitted in a foreign patent proceeding does not make it any more trustworthy than any other untested assertion offered by an adverse party in a legal proceeding.

Thus, we understand CamelBak’s arguments during reexamination to have distinguished the purely rotational (i.e., circular) motion of the claimed mouthpiece from a mouthpiece that moves with a translational component relative to the pivotal axis. In sum, this reexamination history shows that, by distinguishing over the translational motion of McDonough’s mouthpiece, CamelBak limited the claimed mouthpiece to one that (1) maintains a circular path of constant radius about the pivotal mount’s axis of rotation, and (2) does not include a path that has a translational component relative to the pivotal axis.

      “Those detailed descriptions demonstrate that “adapted to,” as recited in claims 1 and 20, means that the resilient mouthpiece is specifically designed and configured to dispense fluid as a result of a user biting the mouthpiece, rather than merely being “capable of” being compressed. See Giannelli, 739 F.3d at 1379–80. Indeed, as disclosed, a distinct benefit of the resilient mouthpiece being bite-actuated “is that a user may position the drink bottle (and mouthpiece) to a desired drinking orientation, and even a partially or completely inverted orientation, without drink fluid being dispensed from the mouthpiece” until the user bites upon the mouthpiece to commence fluid flow through self-sealing valve to the user. Id. at 10:9–19. Thus, the intrinsic evidence, i.e., the specification and figures of the ’255 patent, confirm that the phrase “adapted to” means “designed or configured to” and is not satisfied by mere hypothetical capability. That is, as claimed, the resilient mouthpiece is designed or configured to compress based on actual forces applied by a user’s teeth, as opposed to merely being capable of compression based on the inherent nature of the mouthpiece’s material.

It repeatedly, consistently, and exclusively describes cross-over errors as arising from the formation of chimeric molecules during the amplification step of the sequencing workflow. See Ex. 1001, Fig. 1, Fig. 2, 4:29–52 (describing “improper molecular overlap via formation of a heteroduplex between patient A’s nucleic acid template and patient B’s nucleic acid template” “[w]hen the amplification process begins”), 5:29–58 (the same), 6:25–44 (the same), 6:64–7:23 (the same).” slip op. at 15

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Petitioner asserts that a person of skill in the art (“POSA”) “would have had (i) a Ph.D. in molecular biology, genetics, bioinformatics, or a related field and at least two years of experience in high-throughput sequencing technologies or (ii) a Master’s degree in one of the same fields with at least four years of experience in high-throughput sequencing technologies.” Pet. 17 (citing Ex. 1003 ¶¶ 19–20). Patent Owner states that it adopts Petitioner’s proposal for a POSA for purposes of this proceeding. PO Resp. 13 (citing Ex. 2001 ¶¶ 19–22). We adopt Petitioner’s proposed definition of the skill level as it is consistent with the prior art’s demonstration of the level of ordinary skill in the art at the time of the invention. We find both Dr. Spellman and Dr. Adalsteinsson are qualified to opine from the perspective of a POSA, because each has at least ordinary skill in the art. See Ex. 1003 ¶¶ 4–15; Ex. 2001 ¶¶ 4–9.” slip op. at 8

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableReasonable expectation not foundNot shown unpatentable

      “The reasonable expectation of success requirement refers to the likelihood of success in combining references to meet the limitations of the claimed invention.” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 9 Because, as explained below, we find Petitioner has not met its burden to show reasonable expectation of success, we do not need to address whether Petitioner has shown sufficient reason to combine the asserted references. 821 F.3d 1359, 1367 (Fed. Cir. 2016); see also Allergan, Inc. v. Apotex Inc., 754 F.3d 952, 966 (Fed. Cir. 2014) (stating that “failure to consider the appropriate scope of the . . . patent’s claimed invention in evaluating the reasonable expectation of success . . . constitutes a legal error”). Here, the claimed invention is a method for reducing template cross-over error. Thus, we must determine whether, in December 2010, an ordinarily skilled artisan would have reasonably expected that the combination of Parameswaran and Gloor would reduce template cross-over error. slip op. at 26

      “Thus, on this record, we are persuaded by Patent Owner’s argument that Parameswaran’s “unexpected perfect pairings of unmatched forward and reverse barcodes” are not cross-over error. PO Resp. 31 (citing Ex. 2001 ¶¶ 116–123). In addition, as Petitioner acknowledges, Parameswaran merely “distinguished,” but did not “discard” sequences with mismatches. Pet. 34. Parameswaran states that “[t]he low false-discovery rate for perfect matches strengthens the argument that any sequence with both 5’ and 3’ barcode motifs will be placed with reasonable accuracy into the correct bin.” Ex. 1004, 8. But, because Parameswaran achieved a “remarkably low misassignment rate,” it did not discard, but included any sequence with a matched barcode. Id. Indeed, Parameswaran explains that “[f]or our purposes, all sequences with a match to one of the two expected sequence motifs were considered as true members of the corresponding dataset.” Id. In its Reply, Petitioner emphasizes Parameswaran’s language “[f]or our purposes.” Reply 14 (citing Ex. 1004, 8). According to Petitioner, “[a] POSA would have understood from Parameswaran that chimeric sequences could be kept or discarded, depending on the sequencing ‘purpose.’” Id. (citing Ex. 1054 ¶¶ 79–82). Petitioner is asking us to deem unpatentable a claim based on its reading of “for our purposes,” a broad, undefined statement, to mean something specific—a suggestion to discard perfect unexpected pairings, which Parameswaran explicitly did not do. See Ex. 1004, 8. Petitioner has not presented sufficient evidence and persuasive argument for us to do so.” slip op. at 24
