Pet. 8 (citing Ex. 1002 ¶ 29). Petitioner also contends that a person of ordinary skill would have been “familiar with, e.g., sensor system design, including inertial and other motion sensor system design, and signal processing” and that “[a] higher level of education or skill might make up for less experience, and vice versa.” Id. Patent Owner agrees with Petitioner’s proposed definition of a person of ordinary skill in the art. Resp. 25. We adopt this uncontested definition of the level of ordinary skill in the art.

      “We are not persuaded by Petitioner’s arguments and find that Patent Owner has the better position for several reasons. First, the record supports Patent Owner’s argument that Mestas’s batteries are much too large to fit within a ring form factor, and “would have to be reduced in size on the 6 There is no Exhibit 2022 in the record of this case. magnitude of 5-10x from its current size to fit in a ring of Schröder.” Resp. 38 (citing Dr. Anthony’s cross-examination testimony at Ex. 2021, 313:12). Second, Petitioner relies on evidence in the Reply that Petitioner failed to specifically identify in the Petition. Compare Reply 3–5 (citing Ex. 1369 ¶¶ 7–14; Ex. 1079 ¶¶ 47, 71; Ex. 2022, 138:7–143:1; Ex. 1002 ¶¶ 96, 337; Ex. 2021, 12–13, 307:7–17; Ex. 2020, 212:6–214:13; Ex. 1081, 130:18–131:14; Ex. 1010 ¶ 168), 9 (referring back to Section § II.B.2) with Pet. 25–26 (citing Ex. 1002 ¶¶ 193–99; Ex. 1010 ¶¶ 157, 163, 168, 201, Fig. 6). More specifically, while the portion of Dr. Anthony’s Declaration cited in the Petition (see Pet. 25–26 (citing Ex. 1002 ¶¶ 193–99)) mentions the Technology Background Section V of his Declaration (Ex. 1002 ¶¶ 42–147), neither Petitioner nor Dr. Anthony sufficiently explains what evidence supports his opinion that it was feasible to incorporate batteries or battery-like devices into finger-rings, or how a person of ordinary skill in the art would have miniaturized a curved battery for incorporation into Schröder’s ring. Ex. 1002 ¶ 196 (describing that rechargeable batteries powering wearable electronic devices were “well-known by 2013” and “had also undergone significant advances in terms of miniaturization and energy density [that] made it feasible to incorporate batteries or battery-like devices such as supercapacitors into smaller form factors, such as finger rings, without sacrificing functionality” such as “lithium-polymer (Li-Po) batteries and solid-state batteries.”). Moreover, some of Petitioner’s citations in the Reply appear to be incorrect as there is no Exhibit 2022 of record in this case, as noted above. These issues undermine the strength of Petitioner’s showing by making it difficult to follow its reasoning, much less identify where in the record that reasoning finds support. See DeSilva v.

      “We credit Dr. Mercier’s testimony over Dr. Anthony’s and agree that Dr. Anthony’s testimony fails to account for the constraints of a substantially smaller form factor in Schröder’s finger-ring as compared to Mestas’s wrist device. Ex. 2018 ¶ 140. 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 ’124 patent, we also have evidence that prior art “finger ring wearables up to the ’124 patent had used ‘coin’ type batteries.” Resp. 40 (citing Ex. 2018 ¶ 140). We credit Dr. Mercier’s testimony that a person having ordinary skill in the art would have looked to a coin type battery for the necessary power requirements of Schröder’s device. Ex. 2018 ¶ 141. 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 patent), Fig. 24; Ex. 2018 ¶¶ 74–84. 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 ¶ 85. We also agree with Dr. Mercier that Dr. Anthony’s testimony lacks evidence or a technical analysis of the power requirements for the various sensors he suggests including in a wearable device and the capacity of the proposed GMBPow battery. See, e.g., Ex. 1002 ¶¶ 94, 210, 214–17; Ex. 2018 ¶ 97. Moreover, Dr. Anthony does not address the issues with the batteries that are identified in the references he discusses. For example, Dr. Anthony does not address Lee’s disclosure that “direct coating of electrode slurry onto plain paper led to the occasional internal-shorting of the device due to the leakage of the electrode material through a large-sized hole in the paper.” Ex. 1019, 2415. In contrast, Dr. Mercier discusses the pitfalls the skilled artisan faced in developing finger-ring devices. See, e.g., Ex. 2018 ¶¶ 77–79 (discussing the issues Rhee’s and Asada’s large rings), 83 (identifying power requirements as a design constraint). For example, Dr. Mercier explains that “flexible or curved batteries include flexible packaging materials such as aluminum laminated films that house the electrodes and electrolyte” such that “once the battery packaging is added to a battery such as GMBPow and then placed within a housing (e.g., external housing shell and internal potting), the resulting device would have dimensions that are not suitable for a finger-worn ring.” Id. ¶ 96 (citing Ex. 2026).” slip op. at 34

      “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. Reply. 23 (“Axion also agrees that the term ‘millisecond time resolution’ is ‘the time between two consecutive impedance measurements for each and every well being evaluated in the claimed apparatus or system.’”). The parties also agree that we do not need to determine whether the time interval between two consecutive impedance measurements is less than 300 milliseconds, as set forth in the definition portion of the specification, or whether it can be met by some other time interval, as suggested by other portions of the specification. See e.g., Ex. 1001, 23:49–55 (explaining that “[i]n some embodiments 500 millisecond time resolution is sufficient”), 24:37–39 (similar); PO Resp. 15 (arguing that “the distinction between 300 milliseconds and 500 milliseconds is immaterial to the dispute in this IPR because Jones teaches a 1.5 second update period, thus at least three times longer than the 500 milliseconds formulation”); Pet.

We agree with the parties 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; 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

      “Given that Jones’s only exemplified embodiment targets a 1.5 second update period, that Jones does not suggest reducing the update period, and that much of Jones’s focus is on benefits other than speed of measurement, Jones’s impedance analyzer seems an unlikely choice for a POSA seeking to take measurements having millisecond time resolution. Put another way, we find no persuasive non-hindsight reason that supports Petitioner’s assertion that the POSA would have sought to apply Jones’s impedance analyzer to Xu-752’s system in order to take measurements in millisecond time resolution.” slip op. at 22

      “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

      “We find that the evidence presented by Patent Owner is sufficient to establish that the Oura Ring Gen. 3 Horizon and Gen. 4 products are commercial embodiments of claim 1 of the ’953 patent and that claim 1 is coextensive in that it encompasses the entire structural apparatus of these products.

But more than just practicing the claimed invention, Patent Owner’s evidence supports that claim 1 recites the overall structure that provides for the particular form factor of the Oura Ring Gen. 3 Horizon and Gen. 4 products, i.e., a fingerring “wedding band” design that allows for the electronic components to be entirely contained within the ring housing with a curved external surface having no protrusions or bulges. 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.”).

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

      “We find Patent Owner’s evidence persuasive to show that the Glu3 substitution results in an unexpected improvement in interconversion stability. As explained above, RP-HPLC was a known technique for separating the topoisomers of human uroguanylin. Ex. 2010, 230–231; Ex. 2011, 27–28; Ex. 2020, 223; Ex. 2028, TRUL00018269; see also Ex. 1063 ¶¶ 37, 40 (Petitioner’s expert confirming same). It was also known that one of human uroguanylin’s topoisomers was biologically active, whereas the other, i.e., what we and the parties refer to as the “inactive” topoisomer, had significantly less or no activity at the same concentration. Ex. 2011, 31 (“compound I shows significant activity in the cGMP producing assay, whereas compound II is practically inactive”); see also Ex. 2010, 238–239 (Fig. 8) (showing the “A isomer” had a potency “with a minimal concentration between 10-7and 10-8 M,” but that the B isomer “had virtually no effect on cGMP level at 10-6 M”); Ex. 2074, 48 (compound II “showed maximal 10% of the activity of compound I at 10-6 M”). The chromatograph for uroguanylin in Patent Owner’s data is consistent with these teachings, showing two peaks representing the active and inactive topoisomers.

The chromatograph for SP-304 shows a markedly different result, i.e., a “single peak,” which was confirmed “using the cGMP T84 cell assay” to represent “the fully active conformer of SP-304.” Ex. 2028, TRUL00018269; Ex. 2024 ¶¶ 208–209.

The American Peptide letter was submitted by the EPO opponent specifically for the purpose of opposing a foreign counterpart to the ’786 patent.

See CAFC Dec. 11–13. First, the Court stated we “should determine, based on the evidence put forward by the parties, whether plecanatide exhibits topoisomerism and whether the testing of the challenged claims should encompass both the active and inactive forms.” Id. at 12.3 Second, the Court instructed us to reconsider what the closest prior art compound is in view of Patent Owner’s “contention that highly pure A-form uroguanylin could be maintained as a lyophilized powder,” noting that “[i]f it is true . . . that uroguanylin can be maintained and therefore tested in its active A form as a lyophilized powder, that would support that the experiments [which were conducted in solution] did not use the closest prior art.” Id.

      “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 ’750 patent states that “the fluid pathway can be a radially serpentine fluid pathway which causes the fluids received in the off axis chamber to flow back and forth around a radius of the off axis chamber,” also using “radially serpentine fluid pathway” to refer to this rotation around the chamber radius “while also traversing a length of the off axis chamber.” Ex. 1001, 4:34–41 (emphasis added). This is the only description of “radially” serpentine flow in the ’750 patent. Notably, the ’750 patent does not use “radially” or “serpentine” to describe a fluid pathway “which causes the fluids to spiral around the central chamber within the off axis chamber along a length of the off axis chamber,” instead referring to such a fluid pathway as a “helical fluid pathway.” Id. at 4:41–44. See CAE Screenplates, Inc. v. Heinrich Fiedler GmbH & Co. KG, 224 F.3d 1308, 1317 (Fed.

We explained that the flow path depicted above, which is equivalent to that of Figure 14 of the ’750 patent, “flows circumferentially about the central chamber.” Id. at 14. We maintain this interpretation. Stated differently, the depicted flow is around a longitudinal axis of the chamber. See MTA PG 6 (describing the flow path depicted above as “a back and forth flow path around a longitudinal axis of the off axis chamber; that is, a circumferentially serpentine pathway”); see also Ex. 2003 ¶ 40 (Dr. Neitzel describing the flow path depicted above as “a back and forth flow path around a longitudinal axis of the off axis chamber”). The flow is not around a radius of the chamber, which Patent Owner recognizes is required for a flow path to be radially serpentine. See PO Resp. 10 (“Patent Owner agrees with the Board’s conclusion in the [Institution Decision] that ‘radially serpentine’ as recited in the claims of the ’750 patent means a back and forth flow around a radius of the off axis chamber.” (citation modified)); PO Sur-reply 2 (agreeing that “radially serpentine” requires “a back and forth flow around a radius of the off axis chamber”).” slip op. at 14

      “We agree with Patent Owner that neither Petitioner nor its witness, Mr. Nixon, has explained adequately how Thurler’s disclosure of its tube e being perforated for two thirds of its length “contemplates other lengths of perforations.” See Pet. 48; Ex. 1013 ¶ 212. Such conclusory assertions fail to apprise us of why an ordinarily skilled artisan would have been motivated to modify Thurler’s device in contradiction to Thurler’s explicit disclosure. We are also not persuaded by Petitioner’s proffered reasoning for modifying Thurler’s device. First, the modification is not a matter of design choice because the perforations allow the gases generated by firing the projectile to pass into the space between tubes e and g where they partially expand. See Ex. 1015, 1:84–91. Thus, modifying the number of perforations necessarily affects the flow of gases through the device. Next, neither Petitioner nor Mr. Nixon explains adequately how reducing the amount of perforation in tube e results in an increased fluid length. See Pet. 49; Ex. 1013 ¶ 213. Rather, although less fluid may enter into tube e with Petitioner’s modification, it appears that that fluid would travel the same distance along tubes e and h as in Thurler’s unmodified device. Finally, neither Petitioner nor Mr. Nixon explains adequately how limiting the amount of gases generated by firing the projectile from entering the expansion zones of tubes g and h provides any benefit. To the contrary, limiting the amount of gases in the manner suggested by Petitioner would reduce the suppression of such gases, resulting in a less effective device. Moreover, Thurler discloses that “there is still a space of a few millimeters between [tubes] e and g which is necessary” to prevent the application of “pressure on the projectile causing the same to deviate.” Ex. 1015, 1:106–2:3. Thus, Petitioner’s modification would not result in the passage of gases occurring only at the first three of Thurler’s tubular sleeves as asserted by Petitioner. Additionally, in the Institution Decision, we explained that Petitioner did not provide adequate reasoning to support the proposed modification of Thurler’s device regarding parent claim 1 to have concentric tubes around the central tube e.

      “We agree with Petitioner that the amendment is broadening. Petitioner’s witness testified that he “wouldn’t call a BB gun a high energy device or a high energy weapon.” Paper 33, 18:4–6. Thus, per Petitioner’s witness, use of a BB gun would not be covered by claim 22, no matter what is discharged from the BB gun. However, if high energy material is discharged from that same BB gun, that use would be covered by proposed substitute claim 43 (assuming the other claim recitations were met). See id. at 21:10–12 (Dr. Neitzel agreeing that “if something produces a high energy material, it automatically is a high energy weapon”). Thus, by deleting “high energy device” and replacing that language with “weapon,” proposed substitute claim 43 impermissibly broadens the scope of claim 22. See Sisvel Int'l S.A. v. Sierra Wireless, Inc., 81 F.4th 1231, 1241 (Fed.

      “We agree with Petitioner that the term “ring” is not limited to a finger- worn ring. All of the challenged independent recite a “wearable ring computing device” (claims 1 and 11) or “ring computing device” (claim 14). Nothing in the claim language itself refers to where that device is worn. Moreover, the fact that Patent Owner has in several related patents added claim language to expressly recite a ring that is “finger-worn” or “worn around the finger” evidences that the plain meaning of the term “ring” by itself does not require such. Ex. 1362, 44:45–46:61 (claims 1–18); Ex. 1363, 44:64–46:56 (claims 1–17); Ex. 1364, 48:22–23 (claim 1); see Nystrom v. TREX Co., Inc., 424 F.3d 1135, 1143 (Fed. Cir. 2005) (explaining that the fact that another claim recites a “wood decking board” suggests the term “board” is not itself limited to one made from wood or cut from a log because “[w]hen different words or phrases are used in separate claims, a difference in meaning is presumed”). This understanding is further supported by the Specification of the ’859 patent. It is true, as Patent Owner asserts, that the Specification describes a preferred embodiment that is a finger-worn ring. See, e.g., Ex. 1001, Figs. 22A–B, 23A (depicting a finger-worn ring). But precedent cautions against importing limitations from the preferred embodiment into claims. See, e.g., Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed. Cir. 2004) (en banc) (“[A]lthough the specification often describes very specific embodiments of the invention, we have repeatedly warned against confining the claims to those embodiments.”). Indeed, the Specification here anticipates such arguments and makes clear that the applicants’ wearable computing device (WCD) is not limited to a ring worn on the finger: The WCD can be in the form of a ring that can be worn on the finger of a human (or animal) user. Although the WCD of the present disclosure is depicted as a ring that can be worn on the finger of a user, other shapes, designs, and form factors can be utilized for the WCD. For example, the WCD can be in the form of a wrist band, bracelet, necklace, earring, or any other type of wearable accessory. In this regard, references to the finger of a user in the present application can be considered to apply to other portions of a human body depending on the form of the WCD, such as wrist, neck, ear, etc. Ex. 1001, 8:51–61.” slip op. at 11

This is particularly problematic given that the figures Petitioner relies upon in Yuen and Mestas uniformly depict larger, wrist/arm-band type devices. See Ex. 1006, Figs. 2–13, 12:52–55 (depicting a “wrist-worn or arm-mounted accessory such as a watch or bracelet”); Ex. 1010, Figs. 1–6, ¶ 151 (same). Thus, Petitioner’s obviousness theory requires multiple modifications to Yuen’s depicted structure: (1) modifying the identified portions of Yuen’s device housing so that they form a waterproof cavity therebetween; and (2) shrinking that device and its components down to a ring designed to fit around a single toe. We credit Dr. Mercier’s testimony that such modifications would require a “complex” re-engineering of Yuen’s existing structure that Petitioner and Dr. Anthony do not sufficiently explain. See Ex. 2018 ¶¶ 108–109, 129–130, 137–138. The testimony in Dr. Anthony’s supplemental declaration does not provide the missing explanation. Dr. Anthony continues to assert that Yuen’s sensor protrusion is sealed in the space between the alleged bounding members, relying on the same annotated versions of Figures 4 and 5, without addressing the fact that according to Petitioner’s own annotations those bounding members only form a shell that is open to the attachment band at either end. See Ex. 1079 ¶¶ 26–28. Indeed, Dr. Anthony appears to acknowledge that Yuen only teaches attaching the sensor module portion of the alleged cavity with watertight glue, but asserts that “it would not make sense to have a device that is waterproof in some areas and not others.” Id. ¶ 29. That assertion, however, is not supported by anything beyond Dr. Anthony’s say-so and ignores that Yuen’s teachings regarding a watertight seal/glue refer only to the sensor package portion of the alleged cavity. See Ex. 1006, 14:66–15:4, 15:10–14. Dr. Anthony’s assertion that Mestas teaches additional “waterproofing techniques” that could be applied to Yuen’s housing is similarly cursory. See Ex. 1079 ¶ 30.

      “filed with the Office a statutory disclaimer disclaiming method claims 16, 17, 19, and 20. See Ex. 2007; see also Tr. 33, 21:1–12 (Patent Owner’s counsel informing the Board that the disclaimer had been filed in the USPTO Patent Center, and Petitioner’s counsel having no objection to the filing of the disclaimer as an exhibit in this inter partes review); Tr. 34:19 1 Petitioner identifies Nokia of America Corporation, Ericsson Inc., and T-Mobile USA, Inc. as real parties in interest. Pet. 72. 2 Patent Owner identifies General Access Solutions, Ltd. as the real party in interest. Paper 6, 1. (Patent Owner’s counsel stating, “General Access has disclaimed method Claims 16, 17, 19, and 20.”). We treat disclaimed claims as if they never existed. See Facebook, Inc. v. SKKY, LLC, CBM2016-00091, Paper 12 at 8 (PTAB Sept. 28, 2017) (expanded panel) (precedential) (“The Federal Circuit has held consistently that claims disclaimed under § 253(a) should be treated as though they never existed.”) (citing, inter alia, Vectra Fitness, Inc. v. TWNK Corp., 162 F.3d 1379, 1383 (Fed. Cir. 1998) (“This court has interpreted the term ‘considered as part of the original patent’ in section 253 to mean that the patent is treated as though the disclaimed claims never existed.”); Guinn 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.”)). Accordingly, the remaining claims challenged in this proceeding are apparatus claims 1–15 and method claim 18.” slip op. at 2

      “of both types of parameters to be stored in the same “device” is consistent with the claim language. The claim recites “a profile parameter storage device,” “said profile parameter storage device for storing [two parameter] values,” and refers to “the values stored at said profile parameter storage device.” Ex. 1001, 13:10–16. Accordingly, the claim language speaks of a single device for storing both types of parameters.12 And, Petitioner does” slip op. at 32

Accordingly, in this case, Petitioner must demonstrate by a preponderance of the evidence that the WiMAX exhibit was disseminated or otherwise made available to interested ordinary artisans outside of the group that created the document. Petitioner has failed to satisfy that burden.” slip op. at 48

    Claims 1–6 were not shown unpatentable because the asserted references did not establish that the claimed second transceiver routes information based on monitored signal characteristics.

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “A person of ordinary skill in the art (“POSA”) at the time of the purported invention would have had either: (1) a Bachelor of Science degree in computer science, electrical or computer engineering, or a related field, and at least 2 years of work or research experience in digital communications systems, such as wireless communications systems and networks, or equivalent, or a Master’s degree in electrical engineering, computer engineering, computer science or similar field. Additional education could compensate for less practical experience and vice versa. Ex. 1002, ¶¶1-46. Pet. 10. Patent Owner does not address the level of ordinary skill in the art. Cf. Ex. 2007 ¶19 (Patent Owner’s declarant, after acknowledging Petitioner’s definition, stating: “Patent Owner has not offered a different understanding of a POSITA, and the PTAB accepted Petitioner’s submission. I accept and use Petitioner’s and the PTAB’s definition of a POSITA.”). Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (recognizing that the prior art itself may reflect an appropriate level of skill in the art). For purposes of this decision, we apply Petitioner’s definition of the person of ordinary skill in the art.” slip op. at 11

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededDecided for patent owner

      “During oral argument, both parties confirmed their respective positions that the claim term “route” needs no construction. See, e.g., Tr. 11:7–9 (Petitioner’s counsel: “Frankly, it doesn’t make any difference to the analysis of the prior art. And so, we don’t believe that the PTAB needs to construe the term route, and so we have not proposed a construction.”); id. at 58:25–59:2 (Patent Owner’s counsel: “You know, I don’t think that you have to define routing in order to decide the case. I think you can do it, you know, just apply whatever plain and ordinary meaning is.”); cf. Tr. 40:14–18 (Patent Owner’s counsel at oral argument: “For the routing itself, you know, there is a District Court construction and that’s a construction that the other—the Petitioner did not ask for determination whether that’s appropriate or not appropriate here. We did not address that as well, so the parties aren’t arguing that that construction should be applied here.”). For the reasons discussed below, we determine that Petitioner has not proven by a preponderance of the evidence that the prior art discloses or teaches, under Petitioner’s articulated theories, that a second transceiver routes information based on monitored characteristics. This is dispositive of the inter partes review. Accordingly, we determine that no claim terms require express construction for purposes of deciding the dispositive issues.” slip op. at 13

    • Expert testimonyPatent owner expert creditedDecided for patent owner

      “Ex. 1004, 5:25–36 (emphasis added). Thus, Palmer discloses that the determination to roam to another cell may be done by the mobile worker’s wireless communication device 20 having a specifically-programmed processor or may be done centrally, with examples being the “network” or central host processor. We disagree that this constitutes a disclosure of the access point 40 performing the roaming determinations. Rather, we find to be persuasive and credible Dr. Chrissan’s testimony that “a POSITA recognizes that an access point does not qualify as ‘centrally, for example, by the network or a central host processor,’” and, “[i]nstead, this phrase refers to one of the centrally located devices such as network 14 or central host processor 12 (in Fig. 1), or a device in administration building 33 (in Fig. 2).” Ex. 2007 ¶ 71 (citing Ex. 1004, Figs. 1, 2). Dr. Chrissan’s opinion is consistent with Palmer’s disclosure, as we will now discuss.” slip op. at 23

      “We determine that Petitioner has not established by a preponderance of the evidence its foundational assertion that Palmer discloses that “access point 40 determines whether roaming by a portable terminal 20 should take place and routes data packets accordingly.” Pet. 26–27; see Technology Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1327 (Fed. Cir. 2008) (“Failure to prove the matter as required by the applicable standard means that the party with the burden of persuasion loses on that point—thus, if the fact trier of the issue is left uncertain, the party with the burden loses.”). As such, Petitioner has not met its burden to show that Palmer discloses, as recited in independent claim 1, a second transceiver that, “based on the first signal characteristics and the second characteristics, routes information to the first mobile station and the second mobile station, respectively,” or, as recited in independent claim 6, “based on the first signal characteristics and the second characteristics, routing, using the second transceiver, information to the first mobile station and the second mobile station, respectively.” Ex. 1001, 10:38–44, 11:19–22. The Petition does not contain a contention that this “route” aspect of the claims would have been obvious. Compare Pet. 25–26 (offering an alternative argument for the monitoring aspect; contending that, “to the extent the Board disagrees that Palmer’s access point 40 performs the monitoring, it would have nonetheless been obvious to a POSA to select the access point 40 to perform the monitoring since it directly communicates with the portable terminals 20.”), with id. at 26–27 (making the anticipationtype contention that “[t]he access point 40 routes information” without an alternative obviousness contention); see also Pet. Reply 12–13 (arguing, under the monitoring-and-routing heading, that monitoring by the access point would have been obvious, but not arguing the same for routing). Petitioner has not shown by a preponderance of the evidence that independent claims 1 and 6 and dependent claims 2–4 are anticipated by or would have been obvious over Palmer.” slip op. at 28
