      “A person of ordinary skill in the art at the time of the alleged invention of the ’770 patent . . . would have had an undergraduate degree in electrical engineering, computer engineering, computer science or a related field along with two years of work experience in the field of communication . . . More education can supplement practical experience and vice versa. Pet. 4 (referencing Ex. 1002 ¶¶ 17–18). Patent Owner does not dispute the level of ordinary skill in the art. PO Resp. 5. For the purposes of this Decision, we apply Petitioner’s undisputed definition of the level of ordinary skill in the art. We find that this definition is consistent with the prior art of record and the skill reflected in the Specification of the ’770 patent.” slip op. at 13

      “to refer to “[a] channel [that] does not have to be fully connected on both ends or actually transmitting a particular type of information to qualify as a channel.” PO Resp. 6. Petitioner asserts that Backhaus teaches transmitting an access telephone number via a data channel in two ways. Pet. 45–46. As will be evident from our analysis below, we conclude that it would have been obvious to employ an IP-based communication. There is no dispute that an IP-based communications channel satisfies the term channel as used in the claims. Therefore, we determine that the term “channel” does not require an express construction to resolve the parties’ disputes regarding the asserted grounds of unpatentability. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms. . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am.

      “not require the pre-call information to be transmitted after the call is received at the switch. The “general rule [is that], ‘[u]nless the steps of a method [claim] actually recite an order, the steps are not ordinarily construed to require one.’” Mformation Techs., Inc., 764 F.3d at 1398. As discussed in greater detail below, we do not find the asserted claims, read in light of the Specification,6 to require that the pre-call information having a bridge number be transmitted after a call to a secondary number is made. We begin with the words of the claim. See, e.g., Phillips, 415 F.3d at 1314 (“[T]he context in which a term is used in the . . . claim [at issue] can be highly instructive.”). The complete “transmitting” step recites: transmitting pre-call information to the handset over the at least one data channel the pre-call information including the bridge telephone number and the handset-associated telephone number, such that the handset is capable of displaying the handset-associated telephone number to a user and, based on user input, accepting the incoming call by connecting with the switch over the at least one voice channel using the bridge telephone number. Ex. 1001, 10:29–37. The plain language of the claims requires that the pre-call information is transmitted such that the handset is capable of displaying the handset-associated telephone number and accepting the incoming call. Nothing in this language precludes the pre-call information from being transmitted before the incoming call is received at the switch— the requirement is that the information makes the handset capable of displaying the handset-associated telephone number to a user and accepting” slip op. at 18

      “The Petition, at page 41, makes the argument. We also do not agree with Patent Owner and Dr. Akl that a person having ordinary skill in the art would not have been motivated to employ IP-based communications for the pre-call information. Dr. Akl testifies that [i]f the relationship number was split into a separate transmission[] and transmitted faster than the call itself, as the Petition appears to suggest, then the relationship number could arrive before the call. In this case, the handset would have a notification relating to a call that is not ready to accept, which would be a bad experience for the user because the user would be able to see the incoming call notification but would be unable to accept it. Ex. 2010 ¶ 81. But this testimony ignores the fact that the scenario discussed in Backhaus is the case where a third party caller calls for the first time, and a relationship number is created. See Ex. 1005 ¶ 53. If the pre-call information arrives before the call, then the SLS module on the phone can use the information to display the caller information once the call is connected. Such an approach may avoid the situation where “unknown caller” needs to be displayed, for example. See id. ¶ 55. Indeed, Backhaus suggests Petitioner’s proposed use. See id. ¶ 73 (“Such channels can be used in setting up the relationship databases, sharing information between the SLS module 105 and the SLS platform 115.”). Because Dr. Akl’s testimony is inconsistent with Backhaus’s express teachings, we give it little weight.” slip op. at 42

      “time “would have had an undergraduate degree in electrical engineering, computer engineering, computer science or a related field along with two years of work experience in the field of telecommunication. . . . More education can supplement practical experience and vice versa.” Pet. 4–5 (citing Ex. 1002 ¶¶ 17–18). Patent Owner does not dispute Petitioner’s assessment of the level of ordinary skill. PO Resp. 6. Determining the level of ordinary skill in the art involves various factors, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citation omitted). The prior art of record also reflects the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Based on the complete trial record, we adopt the assessment offered by Petitioner and undisputed by Patent Owner, as it is consistent with the ’105 patent and the asserted prior art.” slip op. at 7

      “the term, and invited further briefing. Dec. on Inst. 14–15. Patent Owner does not assert that this construction affects Petitioner’s “first way” obviousness assertions. PO Resp. 31. After consideration of the post- Institution briefing, we agree with Patent Owner that Petitioner’s “second way” obviousness assertions rely upon a lack of ordering in claims 1 and 2 such that the transmitting of pre-call information may occur prior to the receiving on an incoming call (Pet. Reply 3); therefore, the term “pre-call information” requires construction to resolve the controversy. The “general rule [is that], ‘[u]nless the steps of a method [claim] actually recite an order, the steps are not ordinarily construed to require one.’” Mformation Techs., Inc. v. Research In Motion Ltd., 764 F.3d 1392, 1398 (Fed. Cir. 2014). As discussed above, we do not find the asserted information having a bridge number be transmitted after a call to a secondary number is made. The plain language of the claim requires that the pre-call information include a bridge number “for connecting the handset to the incoming call at the switch”; i.e., information to be used with respect to the incoming call recited in limitation [1.d]. The transmission of the pre-call information may therefore be at any time such that its contents (the bridge number) may be used with respect to the recited incoming call. Consequently, we do not adopt Patent Owner’s proffered construction.” slip op. at 13

      “whether teachings other than Winbladh would be preferentially considered, improperly frame the obviousness question. Patent Owner and Dr. Akl emphasize that Winbladh uses a “‘host resource’ that manages multiple call legs,” arguing that is different from Backhaus’s “more limited” system that uses a “conventional call routing system.” PO Resp. 36–37 (citing Ex. 2010 ¶ 113). However, the obviousness question is “whether the relevant artisan would be motivated to make the combination to arrive at the claims’ actual limitations,” not whether such a combination would preserve all aspects of either Backhaus or Winbladh. See Axionics, Inc. v. Medtronic, Inc., 2023 WL 4410686 (Fed. Cir. July 10, 2023). Moreover, “it’s not necessary to show that a combination is ‘the best option, only that it be a suitable option.” Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021) (quoting PAR Pharm., Inc. v. TWI Pharms, Inc., 773 F.3d 1186, 1197–98 (Fed. Cir. 2014)). Further, “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference [but rather] what the combined teachings of those references would have suggested to those of ordinary skill in the art.” Facebook, Inc. v. Windy City Innovations, LLC, 973 F.3d 1321, 1343 (Fed. Cir. 2020) (“KSR does not support [the] theory that a person of ordinary skill can only perform combinations of a puzzle element A with a perfectly fitting puzzle element B”). Here, Petitioner’s combination provides for a pre-call transmission of local telephone number #βr, and would logically provide advantage in those situations in which a long distance number was originally used for the connection; i.e., those situations for which Winbladh is purposed. We further note that a combination need not work in all situations for a person having ordinary skill in the art to find it advantageous. See Intel tradeoffs should be weighed when a benefit occurs during only some operating conditions).” slip op. at 39

      “In view of Patent Owner’s clear stipulation that it will not assert any additional claims of the ’733 patent against Samsung, and that it will not assert the ’733 patent against Google, Petitioner’s arguments regarding the large number of claims asserted in litigation fails to show that more than one petition is necessary. Paper 3, 3–4; Prelim. Reply 2–4; CTPG 59. Furthermore, all of the claims asserted in related litigation (claims 1– 14, 19, 21–24, 26, 29, and 30) are addressed in IPR2024-00341. Paper 3, 3; Ex. 1021, 2. Petitioner’s arguments that certain dependent claims are reached only in this proceeding, but not in IPR2024-00341, also fail to show that more than one petition is necessary. Paper 3, 4 (“Specifically, claim 25 is only challenged in the [IPR2024-00341] Petition, and claims 18, 20, and 28 are only challenged in the [present] Petition.”); Prelim. Reply 4–5. None of dependent claims 18, 20, or 28 is being asserted in related litigation, and Patent Owner stipulates not to add any additional claims to its infringement contentions if institution is denied here. Prelim. Sur-reply 3. Thus, Petitioner’s arguments that the present Petition reaches dependent claims 18, 20, and 28, which are not reached in IPR2024-00341, insufficiently shows that more than one petition is necessary. See CTPG 59. Petitioner also argues that the public availability of the primary reference (“TS-23.140”) used in IPR2024-00341 “is open to challenge by Patent Owner.” Paper 3, 1–2. “Patent Owner stipulates that if institution is denied in this proceeding, Patent Owner will not challenge the public availability of the TS-23.140 specification in the -00341 proceeding.” Prelim. Resp. 4. not challenge the public availability of TS-23.140, Petitioner fails to show that more than one petition is necessary. Paper 3, 1–2; CTPG 59, 61 (“If stating that issues are not material or in dispute, the patent owner should clearly proffer any necessary stipulations. For example, the patent owner may seek to avoid additional petitions by proffering a stipulation that certain claim limitations are not disputed or that certain references qualify as prior art.”). Petitioner further argues that the present Petition relies on a different type of primary reference and different art combinations than those in IPR2024-00341. Paper 3, 1–3. Petitioner, though, does not explain specifically why “challeng[ing] the claims from different perspectives” demonstrates that more than one petition is necessary. See id. Further, we agree with Patent Owner that there is substantial overlap in the art and art combinations, such as the substantially similar reliance on Ogawa in both proceedings. Prelim. Resp. 5–7; see also Paper 3, 5 (stating that “Petitioners have purposefully used the same secondary reference (Ogawa) in a similar manner in both petitions” with “similar motivations to combine these secondary references with the respective primary references” and that “Petitioners are presenting only two petitions, with each relying on different primary references, but the same secondary reference (Ogawa) that is applied in the presented combinations in a similar manner”). Given the substantial overlap in the art asserted, Petitioner’s arguments regarding different primary references and art combinations fail to show that more than one petition is necessary.

      “suggest that we categorially disregard Dr. Lin’s declaration. As a general point, our precedential decision in Xerox does not provide a blank condemnation of declaration testimony that is identical or virtually identical to language in a paper. Xerox found that the “cited declaration testimony is conclusory and unsupported, adds little to the conclusory assertion for which it is offered to support, and is entitled to little weight.” Xerox at 15; see also 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Here, Dr. Lin cites to evidence to support certain testimony. See, e.g., Ex. 1003 ¶ 73 (citing to Ex. 1007 and Ex. 1011). Also, we do not rely on the Lin Declaration as evidence of any legal standard or for Dr. Lin’s legal conclusions. Rather, we rely on the Lin Declaration to support our factual determinations regarding the teachings of Backhaus, Saksena, and Taylor, as well as why and how a person of ordinary skill in the art would have combined those teachings. Finally, Patent Owner’s arguments go to the weight of Dr. Lin’s testimony. We assess the appropriate weight to give the testimony in our analyses below.” slip op. at 15

      “provided a motivation to combine the teachings of a PSTN interface in Backhaus’s system, even though Backhaus discloses interfacing with the PSTN. Backhaus is silent as to how its system interfaces with the PSTN. As such, we agree with Petition that a person having ordinary skill in the art would have been motivated to connect SLS platform 115 with the PSTN and to also include a PSTN interface in order to facilitate such an connection when implementing Backhaus’s system and processes—such that SLS platform 115 could provide the disclosed second line services to many device users connected to the PSTN that is known to provide reliable communications. Pet. 50. Indeed, Patent Owner’s argument that Backhaus discloses interacting with the PSTN strengthens Petitioner’s position, demonstrating that a person having ordinary skill in the art, when considering Backhaus’s and Taylor’s teachings together, would have used a PSTN interface to ensure a connection with a PSTN. Cf. Pet. Reply 19 (“Rather, it shows that a [person having ordinary skill in the art] would have been motivated to ‘include a PSTN interface similar to that discussed in Taylor when implementing Backhaus’s telephony service system.’” (citing Pet., 49–51)).” slip op. at 32

    • Adverse judgmentAdverse judgmentGranted

      “Under 35 U.S.C. § 42.73(b), a party may request judgment against itself at any time during a proceeding. Also, under 37 C.F.R. § 42.73(b)(2), actions construed as a request for entry of adverse judgment include disclaimer of a claim such that the party has no remaining claim in the trial. Here, Patent Owner has not only disclaimed all of the challenged claims of the ’224 patent, such that no claim remains in this proceeding, but also expressly requests entry of adverse judgment. Therefore, under § 42.73(b), adverse judgment is appropriate. Accordingly, we grant Patent Owner’s requests and enter adverse judgment against Patent Owner pursuant to § 42.73(b), thus terminating this proceeding and cancelling the portion of the July 16, 2024 hearing that was allotted to this proceeding and the ’224 patent.” slip op. at 2

      “Petitioner filed a Notice of Appeal of the Final Written Decision with the Federal Circuit. See Paper 39. On October 13, 2023, the Federal Circuit issued a decision in the appeal vacating our Final Written Decision and remanding for further proceedings consistent with its decision. Sony, 2023 WL 6773879. The Federal Circuit found that our determination that Petitioner’s asserted reference Wiltshire does not disclose the “generating” limitation of claims 1 and 8 was not supported by substantial evidence. Id. at *2–4. The Court vacated our Final Written Decision and remanded for further proceedings consistent with the Court’s opinion. Id. at *5. After the Federal Circuit issued its mandate, we asked the parties to propose a procedure on remand. Ex. 3001, 2. The parties proposed an agreed-upon procedure to allow post-remand briefing with no additional evidence or expert declarations. Id. at 1. We issued an Order authorizing each party to file opening and responsive briefs. Paper 43. The parties then filed the following briefs: Petitioner’s Opening Brief Pursuant to Paper No. 43 (Paper 47, “Pet.

      “6773879, at *4. The Federal Circuit concluded that was improper. As the Court explained, “the existence of those examples does not exclude other examples where new images are created,” and “[a]lthough both parties agree[d] the game Doom requires creating new images, [we incorrectly] determined that listing Doom in the specification was not a sufficient disclosure.” Id. Contrary to Patent Owner’s assertion, the logical conclusion from the Federal Circuit’s reasoning is that our finding that Wiltshire is silent as to the content of that compressed MPEG stream has now been rejected. We must “credit[] Wiltshire’s disclosure of applying its system to video games like Doom, which require ‘generating’ new images.” Id. Based on that reading of Wiltshire, Petitioner persuasively shows that the combination of Wiltshire and Saha teaches compressing those new images using MPEG and transmitting those as compressed frames. Dr. Fuchs testifies that a person of ordinary skill in the art would have understood from Wiltshire’s disclosure that “if the image is displayed or updated, it is then sent to the client in the form of a ‘video stream,” and that “[t]ransmitting the updated images as a video stream allows Wiltshire’s system to be used with the wide variety of games it contemplates, including arcade games (like Doom) that continually update images on the screen.” Ex. 1033 ¶ 46; see also id. ¶ 49 (“The video stream must be dynamically generated because Wiltshire system must be capable of playing real-time interactive games like Doom.”); Pet.

      “Based on the present record, we determine that Petitioner has made a sufficient showing as to this limitation for purposes of institution. In this regard, Petitioner has introduced sufficient evidence at this stage of the proceeding that one of ordinary skill would have been motivated to combine Rao and Araujo as Petitioner proposes. This evidence includes the testimony of Dr. Butler that one of ordinary skill “would have found it obvious to combine a Remote Access Client as taught by Rao with a PPM and request deflector as taught by Araujo to provide a client that better ‘use[s] the energy in a way that strikes a balance between providing functionality and maintaining longevity of the charge.’” Ex. 1003 ¶ 75. It also includes Dr. Butler’s testimony that, in implementing Rao’s filtering, prioritization, and queuing functionality, one of ordinary skill “would have perceived opportunities for improving the policy management capabilities already present in Rao to impart additional advantages, such as optimizing power use,” and would have known that “mobile devices use techniques for optimizing the use of constrained resources, including network bandwidth and battery power.” Id. ¶ 77. Dr. Butler further explains that one of ordinary skill “would have recognized the importance of power management at least because, in mobile devices, applications cannot execute without sufficient power.” Id. Additionally, Dr. Butler testifies that, for these reasons, one of ordinary skill “would have looked to policy-based power management such as taught in Araujo to serve as one of Rao’s ‘multitude of ways to define client-side application priorities,’” to create a device that “would both manage power according to the PPM techniques of Araujo and manage network use according to the techniques of both Rao and Araujo.” Id. ¶ 78. And, Dr. Butler explains, based on Rao and Araujo, one of ordinary skill “would have understood and found obvious that policy enforcement” in the Rao-Araujo combination “may be based on application state (foreground, background) and power state (battery/plugged-in). Id. ¶ 80. We determine that this testimony is reasonable and credible based on the record presently before us, and is unrebutted by countervailing evidence from Patent Owner. We also determine that Petitioner has introduced sufficient evidence that one of ordinary skill would have had a reasonable expectation of success in achieving the proposed Rao-Araujo combination. This evidence includes the testimony of Dr. Butler that one of ordinary skill “would have expected success integrating a PPM and deflector components as taught by Araujo into a remote access client as taught by Rao,” that “the request deflector (Araujo) and packet capture mechanism (Rao) serve similar functions,” and that “[c]ombining such functions would have required only routine programming skill well within the skill set of” a person of ordinary skill.
