Instead, we find the term mentioned in relation to embodiments and examples. See, e.g., Ex. 1001, code (57), 4:17–25. Claim 8 of the ’404 patent recites that “owner identification information includes a name and a description of the owner of the mobile device” but, as Petitioner notes, the doctrine of claim differentiation suggests the term as used in claim 1 should be construed more broadly.

“After review of the ’404 patent’s description, we find no disclosure that pressing the panic button together with another button causes the panic button to ready itself to perform functions (1) and (2) as recited in limitation 1[d]. The closest descriptions we find to limitation 1[d] are that the safety switch readies the panic button to contact 911 (Ex. 1001, 6:59–62), that the panic button may be activated by pressing the panic button with another button (id., 3:59–67, and that the panic button may start a speech recognition process that can trigger the device (id., 7:61–62). Consequently, claim 1 is itself the best source for determining what the claim language means. We determine that the ordinary and customary meaning of the “ready itself” feature of claim 1 is that the panic button “prepares itself to be triggered to perform the panic button functions (1) and (2).” Since the intrinsic evidence is sufficiently clear to discern the meaning of the “ready itself” limitation, we do not resort to extrinsic evidence. See Phillips, 415 F.3d at 1317 (explaining that extrinsic evidence is less significant than intrinsic evidence); Seabed Geosolutions (US) Inc. v. Magseis FF LLC, 8 F.4th 1285, 1287 (Fed.

“Thus, the ’353 application describes that moving the safety switch into position readies the panic button to contact 911, which is not the same as the panic button being activated to ready itself to perform functions (1) and (2) required by claim 1 of the ’404 patent. Patent Owner’s reliance on disclosures elsewhere in the ’353 application is unavailing.

For example, while the ’353 application does mention voice activation with a codeword and activation by depressing of the panic button together with another button (see, e.g., Ex. 1006, 17, 21, 24–25), it does not mention that depressing the panic button together with another button causes the panic button to ready itself to perform recited functions (1) and (2). The application explains that “[t]he [panic] button can send a signal to a controller inside the device to activate [the code word activation] process” and “[t]he [panic] button can start the speech recognition process in one embodiment, to trigger the device.” Ex. 1006, 25. But that describes readying the device for activation by the code word, not readying the button to perform the recited functions. The ’353 application also mentions the word “ready” in relation to using a self-defense mechanism such as pepper spray, which does not appear to be related the readying of the panic button recited in claim 1. Ex. 1006, 15, 19–20. Petitioner has thus met its burden to demonstrate that claims 1–8 of the ’404 patent lack written description support for a panic button adapted to “ready itself” to perform the recited functions because the limitation is not present in the ’353 application to which the ’404 patent claims priority.3 Pet. 8–10.

“DiPerna964 discloses a separate “safety” switch that readies the panic button to contact 911 upon being pressed (Ex. 1028 ¶ 41), but there is no mention of pressing the panic button together with another button to cause the panic button to “ready itself” to perform panic button functions (1) dialing a public or private network for an emergency purpose and (2) activating the transmitting unit, as limitations 1[d] and 1[e] require. DiPerna964 mentions pressing two buttons together to activate the panic button (see, e.g., Ex. 1028 ¶¶ 17, 23–25, 27), but not to “ready itself” to perform recited functions (1) and (2). Petitioner relies on Strack’s triggering the collection of audio, video, and location data for transmission to a remote location as equivalent to a panic button readying itself to, when activated, perform the panic button functions (1) dialing a public or private network for an emergency purpose and (2) activating the transmitting unit. Pet. 15–17 (citing Ex. 1002 ¶¶ 76–88). We do not agree with Petitioner’s contention because Petitioner fails to explain how Strack’s button press that collects and then transmits audio, video, and location data would ready the panic button to perform recited functions (1) and (2).

“1. Level of Ordinary Skill in the Art Petitioner asserts that one of ordinary skill in the art “would have at least a Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field, and 2-3 years of experience in memory system design,” or, alternatively, “a Master’s degree in one of those fields and 1-2 years of relevant experience.” Pet. 9 (citing Ex. 1003 ¶¶ 26–29). Patent Owner “does not contest Petitioner’s definition of a person of ordinary skill in the art, but it reserves the right to do so in the event that trial is instituted.” Prelim. Resp. 7.

“Petitioner asserts that “that no construction is necessary for any terms for the purposes of this Petition as the challenged claims are invalid under any reasonable construction.” Pet. 9. Patent Owner states that “the Board need not construe any claim term in a particular manner to arrive at the conclusion that the Petition is substantively deficient.” Prelim.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable
“to combine Johnson and Moss is inadequate. See Prelim. Resp. 20–24. We tend to agree. In the “Motivation to Combine Johnson and Moss” section, the Petition first asserts that “Johnson and Moss are in the same field of endeavor,” which is insufficient without more to provide a motivation. See, e.g., Sisvel Int’l S.A. v. Sierra Wireless, Inc., 82 F.4th 1355, 1364 (Fed. Cir. 2023). The Petition then asserts that “[t]o provide enhanced flexibility, [one of ordinary skill in the art] in possession of Johnson would look to Moss to incorporate a plurality of delay elements to the data strobe signal.” Pet. 22. This is not persuasive because (a) Petitioner argues that Johnson already provides a plurality of delay elements, (b) Petitioner fails to explain where or how additional delay elements from Moss would be added to Johnson, and (c) Petitioner fails to explain how or why the modification would “provide enhanced flexibility,” or even what “enhanced flexibility” might mean in 9 “a first sampling circuit to sample the first delayed data signal based on the strobe signal” 10 “a second sampling circuit to sample the second delayed data signal based on the received strobe signal” this context. Petitioner also argues that “Moss further discloses that the size of the data path – i.e. the number of data pins in each data path – is a design choice well within the knowledge and ability of a POSITA, and expressly recites examples of 4, 8, and 16-bit wide data paths.” Pet. 23. We agree that varying the width of the data path would have been within level of ordinary skill and would have depended on the particular application, but the Petition fails to explain how or why that would have made it obvious to incorporate various elements of Moss into Johnson.” slip op. at 19

“Petitioner contends that “[a] POSITA would have been motivated to incorporate the termination circuitry disclosed in Greeff with the system of Meaney to achieve enhanced system performance and reliability.” Pet. 53 (citing Ex. 1002, app. A at 82). As support, Petitioner asserts that “Greeff’s termination circuitry ensures proper signal integrity and reduces reflections in high-speed data transmission systems.” Id. (citing Ex. 1006, 1:28–31, 4:10–12, 8:3–5; Ex. 1002, app. A at 82). Petitioner further asserts that “Meaney’s calibration techniques, when applied to the termination resistance and transistor drive strength of Greeff, would ensure that these parameters remain optimal throughout system operation.” Id. (citing Ex. 1002, app. A at 82); see also id. at 54 (“A POSITA would have found it obvious to apply Meaney’s calibration process to Greeff’s termination circuitry in order to optimize the termination resistance and drive strength of the termination circuitry.”). Petitioner adds that “[a] POSITA would have had a reasonable expectation of success in combining Meaney and Greeff.” Id. at 54. According to Petitioner, “[t]he integration of Greeff’s termination circuitry into Meaney’s system would have been straightforward and cost-effective,” any “required modifications are minimal, and the results of the combination are predictable, given the complementary nature of the technologies.” Id. (citing Ex. 1002, app. A at 82). Patent Owner does not dispute Petitioner’s analysis for this limitation. See Prelim. Resp. Based on Petitioner’s argument and evidence, we are persuaded that Petitioner has shown sufficiently for purposes of this Decision that its proposed combination of Meaney and Greeff teaches or suggests the recited “circuitry” of limitation 17a. We also are persuaded that Petitioner’s proffered reasoning for modifying Meaney’s system to include Greeff’s termination circuitry, namely, to ensure proper signal integrity and reduce reflections, is sufficient to support institution.

“The Director has broad authority to exercise discretion to deny a petition under § 314. However, Patent Owner does not assert that Petitioner is a real party in interest with United Patents or allege that Petitioner is in a special relationship with Unified Patents based on its membership status, with respect to the EPR. See Paper 11, 5; Ex. 2013, 8–12 (different IPR finding no special relationship between Hulu and Unified Patents); Fintiv, Paper 11 at 13–14 (“If a petitioner is unrelated to a defendant in an earlier court proceeding, the Board has weighed this fact against exercising discretion to deny institution under NHK.”). In addition, the EPR involves only independent claims 1, 10, 19, and 27 and a different combination of prior art. See Ex. 2009, 1, 6 (relying on Wu, Rosenberg, and Angel, or Wu Rosenberg, Eldering, and Engel). In general, “a person who is not the owner of a patent may file with the Office a petition to institute an inter partes review of the patent.” 35 U.S.C. § 311. Accordingly, we determine that the circumstances outlined do not tilt toward exercising discretion on this record to deny the Petition.” slip op. at 8
- PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Denied
“Petitioner is correct. As summarized above, Fintiv factors 1–5 do not favor exercising discretion to deny the Petition so there is no need to address whether the merits are compelling. See Volvo Penta, Paper 15 at 4–5 (“On remand, if the Board determines that Fintiv factors 1–5 favor exercise of discretion to deny institution, the Board shall consider whether the record prior to institution demonstrates that the merits are compelling” (emphasis added)). In addition, as determined below, Petitioner shows that there is a reasonable likelihood of prevailing on the merits with respect to at least one challenged claim. Therefore, Fintiv factor 6 favors not exercising discretion to deny institution. Based on the foregoing discussion, a holistic review of the record favors not exercising discretion to deny institution. Accordingly, we decline to exercise discretion to deny institution under 35 U.S.C. § 314 based on Fintiv.” slip op. at 16
