“First, the claims use present-tense language, “one or more other connections, which have respective bandwidths and which are permitted to share a bandwidth allocation with the new connection.”3 Ex. 1001, claim 1 (emphasis added). The exclusive use of the present tense have indicates “other connections” must have current possession of the bandwidth. For these other connections to share bandwidth with a newly established connection, they must already exist and have bandwidth ready for immediate use, rather than merely holding a dormant “reservation” pending a network failure. See PO Supp. Br. 1. The Federal Circuit addressed a similar situation where the Court found the present-tense limitation “is connected to the computer network” means a device was required to be connected at the” slip op. at 15

“combination, do not teach or suggest limitations 1.2 and 1.3 requiring: providing a sharing definition specifying one or more other connections, which have respective bandwidths and which are permitted to share a bandwidth allocation with the new connection, such that a total bandwidth allocated jointly to the new connection and to the other connections in any given segment is equal to a maximum of the requested bandwidth and of the bandwidths of the other connections in the given segment Ex. 1001, limitations 1.2, 1.3 (emphasis added); see PO Resp. 17–22; Sur-reply 4–5, 12–14. As discussed above in Section II.C.2, we interpret “other connections” to mean “existing connections in the network that already have bandwidth allocated to them.” Because the information shared in Dziong and Sathyanath, described below, relates to reserved protection paths, rather than existing connections that have bandwidth that can currently transmit network traffic, the references do not teach or suggest the “other connections” part of the sharing definition in limitations 1.2 and 1.3. Dziong describes advertising, across the network, the amount of bandwidth reserved for recovery on each link that would be activated when a protected link fails. See, e.g., Ex. 1005 ¶ 60; Pet. 36. Once activated, network traffic from a “primary path” failure is rerouted to these recovery paths. See Ex. 1005 ¶¶ 7–9, 70, 83. Petitioner points to this advertising of the reserved bandwidth information as teaching the claimed “sharing definition.” Pet. 33–36 (arguing that the “protection paths [in Dziong] have bandwidth reservations” and “share an overall protection bandwidth reservation”); Reply 21–23. However, since the advertised information only contains information about the recovery paths “that would be activated” upon a primary path failure, such paths are not existing connections that already have bandwidth allocated to them, and therefore do not teach the claimed “other connections” that are part of the sharing definition.

“We do not agree that Zalewski is substantively identical to Willgert. As discussed below in Section IV.D.4.c), Zalewski disclosed an RFID transponder in a removable cover for a phone that was completely separate from the voice call components of the telephone itself. Ex. 2001, 7:63–8:3. Based on this, Applicant successfully distinguished Zalewski because the RFID transponder functionality, being contained in a removable cover, was completely independent of the phone device, and thus the claim requirement of a “communication device determining the mobile communication device is in an operational space” was not met. Ex. 1002, 94–95. On this basis, Applicant also argued that claim requirements of switching between a voice call state and an RFID transponder state were not met.

“not agree, based on the current record, that the claims should be construed to encompass a device that has independent RFID transponder components that are separate from and independent of the components that provide voice call capability. During prosecution of related applications, in distinguishing Zalewski, Applicant disavowed such a broad interpretation. For example, Applicant asserted: The term “transceiver” . . . is well understood by those of ordinary skill in the art. One of ordinary skill in the art would not reasonably interpret a "transceiver" so broadly as to incorporate an entire mobile device's circuitry, and in particular to be read on by two separate transmitters . . . . Ex. 1008, 40. Also: [A] person having ordinary skill in the art would have understood “a transceiver of a mobile communication device” to be a transmitter and receiver combined in a single package/housing/unit and sharing at least some common circuitry for both transmission and reception located within a mobile communication device. . . . . A person having ordinary skill in the art would understand Applicants’ disclosure as describing a single transceiver that can be switched from a first state in which it transmits voice call signals to a second state in which it transmits RFID signals. Id. at 92, 94. However, Petitioner also argues, and provides expert testimony in support, that it would have been obvious to integrate Willgert’s communications unit with the voice call capability of a mobile telephone. Pet. 53–54 (citing Ex. 1003 ¶¶ 129–130). At this stage of the proceeding, we find support for this position, including the fact that Willgert specifically teaches that the communications unit can be integrated into a mobile telephone. Ex. 1004 ¶ 32. Patent Owner challenges this argument based on the statement in Willgert that the communications unit can be “constructed so that the transponder will also function when the mobile telephone is switched-off.” Prelim. Resp. 13–15 (citing Ex. 1004 ¶ 31). However, Willgert provides this as one option, and we do not find that this statement teaches away from a fully integrated approach alternative.” slip op. at 30

“Petitioner argues that this combination would have been motivated by the fact that the Willgert teaches that integrating its communications unit into a mobile telephone designed for Bluetooth communication was a “highly user-friendly application,” and that it was well known practice to use a Bluetooth headset wirelessly communicating with the phone to enable hands-free phone calls, as specifically taught by Mooney. Pet. 12–14 (citing Ex. 1004 ¶¶ 8, 30–32; Ex. 1005, Fig. 3, ¶¶ 7, 39, 46–48; Ex. 1021; Ex. 1003 ¶¶ 72–76).

“Willgert/Mooney combination does not teach or suggest the voice call signal requirements of the claims. As stated in the ’984 patent, the voice call signals relate to “the primary function of [the mobile communications device], i.e. to facilitate a user in communicating with another user of another communication device.” Ex. 1001, 3:47–49. The proffered combination of wirelessly connecting a Bluetooth headset to the Bluetooth receiver/transmitter of Willgert’s communications unit includes the fact that the Willgert communications unit is integrated into a mobile telephone. Ex. 1004 ¶¶ 30, 32. Thus, when the telephone is being used for its “primary purpose” of communicating with another user, the same voice call signal involved in that communication is also being transmitted from the telephone to the Bluetooth headset. We see no reason why the claimed “voice call signals” must be construed to exclude such signals. Patent Owner declined to address claim construction in its Preliminary Response, but is free to explore this issue post-institution. We also disagree, based on the current record, with Patent Owner’s assertion that Willgert’s RFID transponder 2 does not transmit “RFID transponder data” or “RFID transponder signals.” The very term itself — RFID transponder — as well as the explicit disclosures in Willgert, establish that the RFID transponder transmits RFID signals and data. Ex. 1004 ¶¶ 4, 14–19. Although, as Patent Owner points out, the ’984 patent discloses embodiments that “emulate” an RFID transponder, there is no reason to confine the scope of the claims to the disclosed embodiments and there is nothing in the ’984 specification or claims that disavows including Willgert’s RFID transponder within the scope of the claims. Also, Patent Owner’s reliance on the prosecution history regarding the Zalewski patent is misplaced. As Patent Owner has explained, Zalewski disclosed “‘an RFID transponder 110’ embedded in a removable cover for a phone or other device ‘such as an MP3 player.’” Prelim. Resp. 14 (citing Ex. 2001, 7:63–8:3). Based on this, Applicant successfully distinguished Zalewski because the RFID transponder functionality, being contained in a removable cover, was completely independent of the phone device, and thus the claim requirements of a transceiver or transmitter switching between a voice call state and an RFID transponder state were not met. Ex. 1002, 18, 91, 134–135, 155; Ex. 1009, 530. Zalewski was not distinguished based on whether or not the RFID transponder was emulated. Again, Patent Owner is free to explore the scope of the claim terms “transceiver” and “transmitter” post-institution.” slip op. at 22

“Patent Owner contends that “Petitioner’s alleged motivation for modifying Ramos’ Zlider to be transparent is superficial and conclusory.” Prelim. Resp. 24; see generally Prelim. Resp. 24–26. As noted above, Petitioner relies on evidence from Ording itself and Dr. Cockburn’s testimony that relies on evidence to support its conclusion. Thus, we do not agree with Patent Owner that Petitioner’s motivation is insufficient for institution. Patent Owner also argues, relying on Dr. Davis’ declaration testimony, that the Vernier on a semitransparent Zlider widget would be “completely illegible” in some circumstances “rendering the very core of Ramos’ work unusable.” Prelim. Resp. 24–25 (citing Ex. 2001 ¶ 88); see Ex. 2001 ¶ 88 (not adding reasoning or evidence beyond that in the Patent Owner Preliminary Response). On this preliminary record, it would appear that when the Zlider widget and the portion of the image underlying the Zlider widget are the same color, the semitransparent Zlider widget may not work as well as when the Zlider widget and the underlying image are different colors. That does not outweigh, for purposes of determining whether to institute trial, the prior art evidence that Petitioner offers of the from Ording and other prior art references on which Dr. Cockburn’s declaration testimony relies. Ex. 1003 ¶ 66 (citing Ex. 1025 ¶¶ 77, 94, 101; Ex. 1026 ¶¶ 153, 162); see Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 799– 800 (Fed.

Petitioner also contends, relying on declaration testimony from Dr. Cockburn, that one of ordinary skill would have had a reasonable expectation of success in combining the references in the manner proposed by Petitioner. Pet. 33–34. Petitioner contends that implementing the Zlider widget “described in the Ramos Paper and Ramos Video in a device, as taught by Ording, would have required only routine knowledge well within the skill of a POSITA” and would involve “combining prior art elements according to known methods to yield the predictable results” described by Petitioner’s proposed combination of the references.

“On this record, we preliminarily agree with Petitioner that the claim limitations amount to a combination of known elements that a POSITA could have combined to achieve predictable results. See Intel, 21 F.4th at 799–800 (determining that a showing of the obviousness in predictable use of prior art elements according to their established functions requires only a showing that the combination be a suitable option). Among other reasons, the preliminary record supports Petitioner’s arguments that combining the teachings of Blumenberg, Bhumkar, and Griffin amounts to applying known solutions in the field of computer interfaces with predictable outcomes. See Pet. 12–18. As noted above, we encourage the parties to address the scope and meaning of the “when” limitations as a matter of claim interpretation, but we do not currently understand the plain language of Limitation [1.o] to require that the “portion of the second web page” or “menu” is displayed only after expiration of the “second user-configurable predefined duration,” termed by Patent Owner the “Alternative Modification.” Again, we encourage the parties to fully address this issue as a matter of claim construction. We additionally note that, even if we were to interpret the claims to require that the recited functions of Limitation [1.o] occur only the “prerequisite elements” are satisfied, we are still preliminarily persuaded by Petitioner’s arguments that combined teachings of the prior art satisfy the claim elements as a mere combination of known elements combined according to their known functions with predictable results.” slip op. at 27

Resp. 3 (“With respect to claim 1, these three scenarios include: . . . .”); see Ex. 2001 ¶¶ 28 (“As recited in claim 1, the three different claimed functionalities are executed ‘when’ the prerequisite elements are met (described as three scenarios by Dr. Cockburn.”) (citing Ex. 1001, 102:50–103:55; Ex. 1003 ¶¶ 33–35), 29–32 (describing the first, second, and third scenarios). In substance, the parties’ dispute appears to concern whether the plain language of the claims requires that a recited function must be performed only after or in response to expiration of a threshold (and other prerequisites), as opposed to requiring a function that begins before and continues after expiration of a threshold. Notably, dependent claim 3 recites: “The electronic device of claim 1, wherein the electronic device is configured such that the first feedback that is perceptible by touch is output prior to the display of the menu.” Ex. 1001, 104:1–4 (emphasis added). Given that independent claim 1 is necessarily broad enough to include claim 3, it seems on this record that the functions recited in Limitation [1.o] necessarily can happen at different times, as opposed to, for example, only responses that are triggered by the so-called “prerequisite elements.” We encourage the parties to address this issue as a matter of claim interpretation in future briefing. Based on the current record, however, we determine that it is not necessary to provide an express interpretation of any claim terms at this stage of the proceeding. See Realtime Data, LLC v.

Resp. 6 (“Patent Owner does not necessarily agree with all aspects of Petitioner’s proposed level of ordinary skill, but does not believe that resolving that level is necessary to resolve the issues raised in this preliminary response.”) The portion of the definition proposed by the Petitioner requiring “a bachelor’s degree in computer science, computer engineering, or a comparable field and at least two years of professional experience working with graphical user interfaces and applications for computers” appears to be consistent with the problems and solutions in the ’758 patent and prior art of record and is supported by declarant testimony.

“We determine that, on this record and for the purposes of institution, Petitioner has made a sufficient showing regarding motivation for its proposed combination of Chaudhri, Martyn, and Griffin. For the combination of Chaudhri and Martyn, we determine, on the present record and for the purposes of institution, that Petitioner has sufficiently shown support for the use of Martyn’s snap-shot menu with Chaudhri’s user interface. We acknowledge Patent Owner’s declarant’s examples of instances in which devices that incorporated “popular user interface features . . . did not achieve the same level of success because of poorly articulated design implementation.” Ex. 2001 ¶ 127 (cited at PO Resp. 23). However, on the present record, this evidence does not specifically address whether one of ordinary skill would have found such examples significant enough or relevant enough to the proposed combination to dissuade one of ordinary skill from considering such a combination to be reasonably likely to succeed, especially in light of the testimonial evidence before us that similar menus were often incorporated into GUIs similar to Chaudhri’s, which is adequately supported by reference to numerous examples. See Ex. 1003 ¶¶ 43–48, 64–65 (cited at Pet. 16). Additionally, we find compelling that Chaudhri describes a pop-up dialogue sub-menu for a different purpose (modifying the user interface object). See Ex. 1004 ¶¶ 274, 317, Figure 5LLL; Pet. 18–19; Ex. 1003 ¶ 69. On the present record, one of ordinary skill in the art would have found the use of the similar snap-shot menu from Martyn (offering different functionality) to be further prompted by this sub-menu, and not to have been redundant or “already solved” in Chaudhri, as Patent Owner argues (PO Resp. 26–27). See Pet. 18–19; Ex. 1003 ¶ 69. introduced to the combination of Chaudhri and Martyn to address a conflict that arises because Petitioner proposes a combination of Chaudhri and Martyn that “create[s] a conflict of assigning two functions to the same gesture.” PO Resp. 20. However, Petitioner provides a number of rationales to combine, and Petitioner’s argument that one of ordinary skill would have sought details from Griffin to implement Chaudhri’s teachings describing different user functionality being launched by user touches of different user durations (Pet. 19–21) adequately supports the use of the material from Griffin in the proposed combination. See Ex. 1004 ¶¶ 217, 218; Ex. 1002 ¶¶ 70–73, 75; see also PO Resp. 24 (describing “multiple types of gestures” used Chaudhri). While the proposed combination of Chaudhri and Martyn would, as Petitioner asserts, result in “three distinct operations invoked by duration-based touch gestures at an application icon” (Pet. 21), two of these distinct operations are found in Chaudhri’s teachings, and thus, on the present record, the motivation to look to Griffin does not arise only from the proposed combination of Chaudhri with Martyn. On the present record and for the purposes of institution, we determine that Petitioner has adequately shown that one of ordinary skill would have looked to Griffin to supply additional information regarding implementation of Chaudhri’s (and the Chaudhri and Martyn combination’s) use of parameters of a user’s touch, including duration, to enable different functionalities. Ex. 1006 ¶¶ 40, 53, Fig. 7; Ex. 1002 ¶¶ 70–73, 75. With respect to the use of the “press-and-hold” feature from Martyn, rather than other possibilities from Martyn for triggering its snap-shot menu and rather than adding a second touch point as Patent Owner suggests (PO Resp. 27–28, 32, 33 (citing Ex. 2001 ¶¶ 142–143, 156, 166, 172–173)), on to have been a suitable option.

See Fintiv at 5 (“When the patent owner raises an argument for discretionary denial under NHK due to an earlier trial date, the Board’s decisions have balanced [Fintiv] factors [1–6].” (emphasis added)); Pet. 67 (arguing that “the court has neither entered a schedule nor set a trial date”); Prelim.

“Petitioner filed both of its petitions in the instant proceedings on the same day, May 31, 2024, and the prior petition in IPR2024-00506 was filed by a different party previously sued for infringement of the ’394 patent in a different district court case. Therefore, there are no serial petitions, as that term is used in General Plastic, filed in these IPRs. However, “our application of the General Plastic factors is not limited solely to instances when multiple petitions are filed by the same petitioner. Rather, when different petitioners challenge the same patent, we consider any relationship between those petitioners when weighing the General Plastic factors.” Valve Corp. v. Elec. Scripting Prods., Inc., IPR2019-00062, Paper 11 at 9 (PTAB Apr. 2, 2019) (precedential). Petitioner argues that “no significant relationship exists” between it and Cisco, as they were “accused of infringing the ’394 patent with different products in different court proceedings . . . and have not coordinated regarding the ’394 patent, the separately accused products, or the filing of petitions for IPR.” Pet. 70. Patent Owner provides no evidence of a significant relationship between Petitioner and Cisco, but nonetheless argues that factors 1–5 favor discretionary denial anyway, because Petitioner had knowledge of the Cisco petition, citing the Board’s decision in Ericsson Inc. v. Uniloc 2017, LLC, IPR2019-01550, Paper 8 at 11–12 (PTAB Mar. 17, 2020) (“Ericsson”), for the proposition that Petitioner’s use of the Cisco petition as a roadmap ties the interests of the petitioners together. Prelim. Resp. 26. We are not persuaded by this assertion. First, Ericsson is not a precedential or informative decision and is not binding on us or informative to our analysis. Moreover, in that case there were five prior petitions that covered all of the challenged claims, and the petitioner admitted crafting its petition based on its review of the prior petitions. Ericsson at 3, 11. Petitioner here has not made such a concession, and moreover, Patent Owner has not presented any evidence that Petitioner actually did use the petition in IPR2024-00506 as a roadmap. Under the circumstances, we find no evidence that Petitioner used the prior petition filed by Cisco as a roadmap, particularly when none of the timing associated with the prior petition was within its control. We find no significant relationship between Petitioner and Cisco. “[W]here, as here, the first and second petitioners are neither the same party, nor possess a significant relationship under Valve, General Plastic factor one necessarily outweighs the other General Plastic factors.” Videndum Prod. Sols., Inc. v. Rotolight Ltd., IPR2023-01218, Paper 12 at 6 (Vidal Apr. 19, 2024).

“sufficient showing that a POSITA would have been motivated to apply Hu’s concept of aggregating ports to form a high-capacity port for transmitting multicast streams to the network device disclosed by Blease, and we do not agree that Blease teaches away from incorporating such aggregation. Both Blease and Hu are directed to similar subject matter, processing multicast stream requests, and Hu’s link aggregation addresses the problem of potentially overloading a port when doing so. See, e.g., Ex. 1005, code (57) (“The network device transmits multicast traffic to the subscriber devices.”); Ex. 1007, claim 17 (“A network device to allocate media streams . . . .”), 1:20–29 (disclosing that, if “insufficient bandwidth [is allocated] to video streams, the quality of service degrades”); see Intel Corp. v.

Cir. 2023) (“That [two prior art references] address the same problem and that [one of the references] was a known way to address that problem is precisely the reason that there’s a motivation to combine under KSR and our precedent.”). On this record, we are persuaded that applying Hu’s port aggregation teaching to Blease’s router would be the application of a known technique to improve the router to allow it to provide multicast streams that require higher bandwidth with predicable results. Pet. 28; see KSR, 550 U.S. at 415–21. As pointed out by Petitioner, these two concepts could be combined together in a straightforward manner and applied to streams that require high-capacity ports, a technique already applied elsewhere in Blease to other ports, so a POSITA would have had a reasonable expectation of success in doing so. Pet. 28–29; Ex. 1003 ¶¶ 93–94; see Elekta Ltd. v. Zap Surgical Sys., Inc., 81 F.4th 1368, 1377 (Fed. Cir. 2023) (“Evidence of reasonable expectation of success, just like evidence of a motivation to combine, ‘may flow from the prior art references themselves, the knowledge of one of ordinary skill in the art, or in some cases, from the nature of the problem to be solved.’”) (quoting Brown & Williamson Tobacco Corp. v. Philip Morris Inc., 229 F.3d 1120, 1125 (Fed. Cir. 2000)). On this record, we are unpersuaded by Patent Owner’s argument that Blease teaches away from using aggregated ports to form a high-capacity link because “Blease’s disclosure is clear that the focus of its multicast techniques is to reduce, not increase, the amount of multicast traffic flowing through network.” Prelim. Resp. 14. The discussion in Blease of minimizing the bandwidth does not relate to restricting the bandwidth required for a particular stream as Patent Owner seems to assert, but rather to eliminating duplicate transmissions of the same multicast stream to be delivered to multiple subscribers. See Ex. 1005, 2:39–42, 4:50–56 (“The multicast transmission techniques described herein may significantly reduce the amount of multicast traffic . . . . For example, regardless of the number of subscriber devices[] connected to the same network switch that request the same multicast stream, [the] network device[] only sends one copy of the multicast stream to the network switch.”). Therefore, aggregating ports to accommodate transmission of a single multicast stream that requires more bandwidth is a different concept that is unrelated to the discussion in Blease about minimizing bandwidth by increasing efficiency.” slip op. at 37
