In the Institution Decision, we agreed with the District Court that “event node” does not need construction, and we continue to do so here. See Inst. Dec. 11–12. As Patent Owner acknowledges, independent claim 12 recites “establishing an event node for the situation in a multi-dimensional personal information network.” PO Resp. 1. Claim 12 further recites “automatically connecting personal information aggregators corresponding to a plurality of individuals to the event node” and “aggregating information related to the situation received from the personal information aggregators connected through the situational network.” Ex. 1001, 33:54–56, 34:1–3 (emphasis added).

“Patent Owner’s argument that Amidon’s social network conference merely comprises a group of individuals communicating with each other so it cannot be an event node does not take into account that Amidon’s social network conference is also defined by a data structure, such as the data structure shown in Figure 3.

“would have found it obvious to combine the teachings of Burfeind and Crowley (Pet. 15–22), citing Dr. Cooperstock’s supporting testimony (Ex. 1003). In particular, Petitioner posits that a POSITA would have sought references for improving upon “Burfeind’s burdensome and imprecise manual participant selection process,” wherein Crowley is such a reference. Pet. 17–18 (citing Ex. 1005, Abstract, ¶¶ 4, 7–8, 45; Ex. 1003 ¶¶ 81–82). Petitioner contends that Crowley’s system provides numerous advantages, such as “enabling ‘spontaneous socializing’ and ‘convenient communication among friends,’” and “help[s] avoid the problem of friends who were out near each other, but never realized it until later.” Id. at 18–19 (citing Ex. 1005 ¶¶ 6, 35). According to Petitioner, “Crowley thus provides express motivation for implementing its location-based features in Burfeind.” Id. at 19 (citing Ex. 1003 ¶¶ 84–86). Petitioner further contends that a POSITA would have a reasonable expectation of success in implementing the features of Crowley in Burfeind. Pet. 19 (citing Ex. 1003 ¶ 89–92). In particular, a POSITA would have readily been able to adapt Crowley’s location-tracking features “to identify user locations for the purpose of inviting individuals who are located near the event location.” Id. (citing Ex. 1003 ¶¶ 89–90). According to Petitioner, Burfeind and Crowley disclose similar systems for organizing meetings between individuals (id. at 22 (citing Ex. 1004, Abstract; Ex. 1005 ¶ 5)), and because Burfeind “already contemplates techniques for grouping individuals in order to more conveniently select those individuals,” a POSITA “would have thus readily been able to modify Burfeind to determine the event organizer’s contacts that are located proximate to selected event venue.” Id. at 21–22 (citing Ex. 1003 ¶¶ 89–92). Thus, according to Petitioner, the POSITA: would have understood that implementing Crowley’s techniques in Burfeind would merely amount to the use of a known technique (Crowley’s location-based messaging) to improve similar systems in the same way (enabling the system to automatically send messages/invitations to nearby individuals), as well as applying a known technique to a known system ready for improvement to yield predictable results.

Thus, we determine that Petitioner has shown by a preponderance of the evidence that the subject matter of claim 1 would have been obvious over Gage. v.

Petitioner generally refers to its contentions with respect to claim 1. Pet. 34–36.

Id. at 34 (citing Ex. 1005 ¶¶ 19, 25).

“We need not reach the issue of whether the preamble is limiting for purposes of determining institution. Even were we to agree with Patent Owner that the preamble is limiting and the claims are limited to a fingerworn ring, at this stage Petitioner has demonstrated that the cited art teaches or suggests such a limitation. That is, Petitioner relies on the fingerring of Schroder for the claimed form factor of a “wearable computing device configured to be worn around a finger of a wearer.” Pet. 22 (Ground 1), 45 (Ground 2, relying on Yuen for adding the functionality of light sources with a photodetector, temperature sensors, and varying the sampling frequency of sensor data acquisition), 56 (Ground 3). Further, to the extent Petitioner contends that Yuen’s toe band or earring is structurally and functionally equivalent to a finger-ring (Pet. 45, 57), Patent Owner has not, at this stage of the proceeding, structurally distinguished a device configured to worn around a finger from a toe band or earring. For instance, Patent Owner has not explained how a device to be worn around a finger differs in size, configuration, or design from a toe band or earring. And the ’124 patent recognizes that “a human being’s finger can come in various different sizes and so should the [wearable computing device].” Ex. 1001, 12:64‒65. For instance, challenged dependent claim 10 recites that the width of the external housing of the wearable computing device is within a range of 3 mm to 8 mm and a thickness of the device is within a range of 1.5 to 3 mm. Id. at 35:8‒12.

“After considering the parties’ arguments and evidence, we determine that Petitioner’s showing of reasons to combine Mestas and Schröder is sufficient for purposes of granting institution of an inter partes review. Although general similarities between the references are usually not by themselves sufficient to show a reason to combine particular teachings, Petitioner here also provides more particularized contentions, such as “[i]mplementing Mestas’s device in Schröder’s ‘finger-ring’ form factor would ensure a tighter fit than a device worn, e.g., on the user’s arm or wrist, reducing motion artifacts, providing better shielding against ambient light, and permitting higher quality reading from device sensors (e.g., accelerometer, heart rate, temperature)” and that Mestas’s concern with “slippage around a user’s wrist or other body part” would have motivated a person of ordinary skill in the art “to consider placing the device on the finger, as in Schröder, to improve traction and prevent slippage.” Pet. 19‒20 (citing Ex. 1002 ¶ 169; Ex. 1010 ¶ 152). These reasons are sufficient to present a reasonable likelihood of prevailing as to at least one challenged claim based on the proposed combination of Mestas and Schroder for purposes of institution.

“Beginning with the language of the claims themselves, Patent Owner does not point to anything that suggests this narrowing construction, and indeed we see nothing there that describes or requires a “quantitative determination[] or estimation[]” or requires use of “one or more algorithms.” See generally Ex. 1001, 23:6–26:59. Patent Owner provides only a single citation to the Specification, which discusses a “quantitative method for estimating or determining the severity of the subject’s sleeping disorder or symptoms” and states that “[v]arious algorithms known to those skilled in the art . . . quantify the level of severity of the subject’s sleeping disorder or symptoms.” See Ex. 1001, 19:61–20:23, cited at Prelim. Resp. 19. The cited portion of the Specification does not purport to expressly define the claim term “data of a severity of the symptoms of the subject.” See, e.g., Thorner v. Sony Comput. Entm’t Am.

Cir. 2012) (internal quotations omitted) (“To act as its own lexicographer, a patentee must clearly set forth a definition of the disputed claim term other than its plain and ordinary meaning.”). Patent Owner also does not presently demonstrate that we should read into the claim term “data of a severity of the symptoms of the subject” a requirement of a “quantitative determination[] or estimation[]” or use of an “algorithm[].” Prelim. Resp. 19. To be sure, the ’029 patent discloses embodiments that use known algorithms to “quantify the level of severity of the subject’s sleeping disorder or symptoms.” See, e.g., Ex. 1001, 20:11–19. But the Specification also appears to indicate that quantification is merely “preferable” (i.e., not required), and is merely one embodiment. See, e.g., id. at 19:8–12 (“The signals from the one or more sensors used in various embodiments of the present invention are preferably analyzed using a processor and software that can quantitatively estimate or determine the severity of the subject’s sleeping disorder or symptoms.”) (emphasis added), 4:51–59 (“Finally, in still another embodiment, the present invention includes a sleeping disorder treatment system comprising a device for diagnosing and creating a quantitative output of a level of severity of a subject’s sleeping disorder or symptoms . . . .”) (emphasis added). Elsewhere, the Specification more generally states that signals from sensors are “analyzed to determine the level of severity of the symptoms,” without specifying that such analysis must be “quantitative” or performed by an algorithm. See id. at 3:41–44. In view of such disclosures, Patent Owner does not persuade us on this record to adopt its narrowing claim construction. Indeed, our reviewing court has “repeatedly warned against confining the claims” to specific embodiments disclosed in the Specification. Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed.

“Regarding Patent Owner’s argument that “a POSITA reading Kumar and Truitt would not be motivated to add that functionality to Truitt’s PAP device,” we find that this argument does not respond to Petitioner’s contentions. As discussed, Petitioner argues that Truitt’s PAP device already calculates severity or index data (see Pet. 17–21), and thus we do not presently understand Petitioner to be arguing that a person of ordinary skill in the art would have added this functionality to Truitt’s PAP device. Thus, Patent Owner’s argument that “a POSITA reading Kumar and Truitt would not be motivated to add that functionality to Truitt’s PAP device” is inapposite in view of Petitioner’s contentions. Even if the proposed combination requires adding an ability to calculate severity or index data, we are not persuaded by Patent Owner’s argument that a skilled artisan would have added it to Kumar, not Truitt, given that “Kumar’s computing device already has the necessary computational resources” to “receive multiple streams of data from the patient’s device and analyze the data before sending it to a remote site.” Prelim. Resp. 18, 17. This argument takes too narrow a view of Kumar. Kumar’s system “allows for the real-time streaming” of not only “raw” physiological data, but also of data that has already been “interpreted” or “processed.” Ex. 1008 (Kumar) ¶ 10. Accordingly, for purposes of institution, we find that Petitioner adequately demonstrates that “a POSITA would have been motivated to combine teachings of Truitt and Kumar such that the PAP device would wirelessly transmit to a patient’s cell phone data associated the patient’s treatment, including . . . the data of a severity of the sleep disorder symptoms of the subject.” Pet. 29–30 (emphasis added).” slip op. at 31

This burden never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015).

“understanding of a person of ordinary skill in the art at the time the invention was made.9 See Graham, 383 U.S. at 17–18. At this stage, the parties agree that a person of ordinary skill in the art (sometimes referred to herein as “POSITA”) would have had: at least a bachelor’s degree in mechanical engineering, electrical engineering, computer science, biomedical engineering, or a similar technical field, with at least two years of relevant product design experience working with diagnostic sensor systems and network data systems, such as networked PAP machines. Additional experience could substitute for less education, and additional education could likewise substitute for less experience.” slip op. at 8

“At this stage, Petitioner has the better argument. Toge teaches that control unit 250 analyzes collected data (e.g., the flow rate) and calculates tidal volume. Ex. 1044 (Toge) ¶¶ 34–38. On this record, we agree with Petitioner that the calculated tidal volume is “a quantified level of severity data based on the subject’s sleep apnea symptoms during the therapy” because it represents, e.g., the “level of airway obstruction the patient experiences during the sleep apnea treatment using the PAP device.” Pet. 15. On this record, Patent Owner’s assertion that the tidal volume is a “breathing metric” instead of “a quantified level of severity data” is unavailing in view of Toge’s teaching that control unit 250 calculates the tidal volume, and its teaching that the tidal volume is used to assess the patient’s condition and determine whether system adjustments are needed. See id. at 15–16; Ex. 1044 (Toge) ¶ 39; Ex. 1003 (Kirkness Decl.) ¶ 157. In other words, on this record, the calculated tidal volume indicates severity because it is used to adjust the PAP system, e.g., in the case of decreasing tidal volume, a medical professional can change the airflow settings “to counter/treat the more severe level of airway obstruction observed from the decreasing tidal volume.” Ex. 1003 (Kirkness Decl.) ¶ 158.” slip op. at 20

Patent Owner does not propose an alternative level of skill. See generally PO Resp. For purposes of this Decision, we adopt Petitioner’s proposal, reiterated by the proposal of Petitioner’s expert, which comports with the teachings of the ’107 patent and the asserted prior art.

“Additionally, we observe Mr. Reid testifies that “Sellberg also describes benefits of adding currency exchange features to a trading system, such as increasing liquidity in the system.” Ex. 1002 ¶ 182 (citing Ex. 1019 ¶ 12). Mr. Reid further explains that “the skilled person would have known that adding currency exchange to a trading system would be a desired improvement.” Id. After reviewing the record, we determine that Petitioner has set forth a sufficient rationale for combining Sellberg’s teachings with Calo’s system. Sellberg discloses a trading system that utilizes an updated exchange rate that is repeatedly and automatically received from the currency market or the market maker, “and the last received updated exchange rate between the different currency and the specified currency at the time of receiving the order is used as the received current exchange rate.” Ex. 1019 ¶ 24. Mr. Reid has explained, with sufficient reasoning and citation to the record, how and why a POSITA would have added Sellberg’s currency exchange features to Calo’s trading system. Ex. 1002 ¶ 182. Thus, based on our review of the complete record, including the testimony of Mr. Reid, we are persuaded that the combination of Calo, Rude, and Sellberg discloses the disputed limitation for the reasons given by Petitioner.” slip op. at 33

“Petitioner asserts that for the term “prevailing exchange rate,” as recited in claims 1, 2, 6, 9, and 10, “[t]he term prevailing commonly means ‘current.’” Pet. 28–29. According to Petitioner, this is consistent with the ’107 patent. Id. Petitioner asserts that “[t]he only rates the Specification describes using are a ‘forward’ rate or a ‘spot’ rate – in other words, a selected current exchange rate.” Id. at 29 (citing Ex. 1002 ¶ 34). Petitioner thus asserts that “‘prevailing exchange rate’ means ‘a selected current exchange rate that is not an FOREX average exchange rate.’” Id. Petitioner further contends that the term “prevailing currency exchange rate,” as recited in claims 2 and 9–11, “is the same as the prevailing exchange rate but limited specifically to currencies.” Id. Patent Owner takes the position that “[f]or purposes of the present IPR, Patent Owner agrees with Petitioner’s proposed definition for both of the terms ‘prevailing exchange rate’ and ‘prevailing currency exchange rate’ in related IPR2024-00375. Namely, ‘a selected current exchange rate.’” PO Resp. 4. For the remaining terms, Patent Owner “submits that they should be given their ordinary and customary meaning as understood by one of ordinary skill in the art in the field of electronic trading as of the date of the invention.” Id. at 5. We do not need to construe any terms expressly to reach our decision. See Realtime Data LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.
