    • PTAB / AIA Trials › Discretionary denial › §325(d) same art / argumentsDecided for petitioner

      “Under 35 U.S.C. § 325(d), the Board may exercise discretion to deny a petition that presents the same or substantially the same art or arguments as were previously presented to the Office. See 35 U.S.C. § 325(d); 37 C.F.R. § 42.4(a) (providing that the Board institutes on behalf of the Director). The Board has outlined factors it considers in determining whether to exercise discretion to deny institution under § 325(d): (a) the similarities and material differences between the asserted art and the prior art involved during examination; (b) the 5 Holloway et al., WO 02/49322 A2, filed Dec. 11, 2001, published June 20, 2002.

Ex. 1007. cumulative nature of the asserted art and the prior art evaluated during examination; (c) the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection; (d) the extent of the overlap between the arguments made during examination and the manner in which Petitioner relies on the prior art or Patent Owner distinguishes the prior art; (e) whether Petitioner has pointed out sufficiently how the Examiner erred in its evaluation of the asserted prior art; and (f) the extent to which additional evidence and facts presented in the Petition warrant reconsideration of the prior art or arguments. Becton, Dickinson & Co. v. B. Braun Melsungen AG, IPR2017-01586, Paper 8, 17–18 (PTAB Dec. 15, 2017) (precedential as to § III.C.5, first paragraph) (“Becton Dickinson”). The Becton Dickinson factors apply when a petition relies on art or arguments previously presented to the Office during any proceeding pertaining to the challenged patent, including reexamination, reissue, and AIA post-grant proceedings. Advanced Bionics, LLC v. MED-EL Elektromedizinische Geräte GmbH, IPR2019-01469, Paper 6, 8–10 (PTAB Feb. 13, 2020) (precedential). Advanced Bionics explains how the Becton Dickinson factors fit into a two-part framework that examines: (1) whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments previously were presented to the Office; and (2) if either condition of first part of the framework is satisfied, whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims. If a condition in the first part of the framework is satisfied and the petitioner fails to make a showing of material error, the Director generally will exercise discretion not to institute inter partes review.” slip op. at 7

      “C. Claim Construction In inter partes reviews, the Board interprets claim language using the district-court-type standard, as described in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See 37 C.F.R. § 42.100(b) (2023). Under this standard, claim terms have their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history. See Phillips, 415 F.3d at 1313–14. Claim terms need only be construed to the extent necessary to resolve the controversy. Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017). Petitioner states that “[n]o formal claim constructions are required in this proceeding.” Pet. 6. However, Petitioner submits “preliminary” claim constructions proposed by the parties in the District Court case, including proposed constructions for the claim terms “transceiver” and “transmitter.” Pet. 7–9. Patent Owner states that it “does not dispute the Petition’s statement on claim construction for the purposes of this Preliminary Response.” Prelim. Resp. 8. Notwithstanding the parties’ statements disavowing the need for claim construction, in our analysis set forth below we consider construction issues regarding the independent claim terms “voice call communication,” “voice call signal,” “transceiver,” and “transmitter.” We invite the parties to further consider these issues going forward.” slip op. at 11

      “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. Ex. 1008, 18, 91, 134–135, 155; Ex. 1002, 530. In contrast, Willgert discloses an RFID transponder that is integrated with a mobile telephone, and so it cannot be distinguished on the basis that was used for Zalewski. Ex. 1004 ¶ 32.

      “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). Petitioner further argues that Bluetooth headsets were widely available, that incorporating the headset involved known methods yielding predictable results, and that one of ordinary skill would have reasonably expected to succeed in combining the teachings of Willgert and Mooney. Id. at 15–16 (citing Ex. 1004 ¶¶ 8, 10; Ex. 1005, ¶ 8; Ex. 1017, 1, 3; Ex. 1021, 2; Ex. 1003 ¶¶ 77–79). Patent Owner does not address the issue of motivation to combine Willgert and Mooney. See generally Prelim. Resp. We find, based on the current record, that Petitioner has provided sufficiently articulated reasoning with rational underpinnings for the proffered combined teachings of Willgert and Mooney.” slip op. at 16

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAOther

      “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

      “First, we find no basis for exercising our discretion to deny institution with regard to the Juniper case because that case does not yet have a scheduling order in place, and, as Petitioner points out, the median time to trial in that district is 34.6 months, which puts the trial in approximately July 2026, so there is nothing in the record to indicate that a trial will occur before our deadline for a final written decision in these proceedings. 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.

Second, following submission of the papers in these proceedings, the Cisco case was dismissed on December 26, 2024. Ex. 3001.

    • PTAB / AIA Trials › Discretionary denial › General Plastic (serial petitions)Denied

      “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. PACT XPP Schweiz AG, 61 F.4th 1373, 1380–81 (Fed. 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

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). Accordingly, based on the particular facts of these proceedings, including the points addressed above, we decline to exercise our discretion to deny the Petitions on that basis.” slip op. at 17

      “access switches on the second port.” Ex. 1001, claim 5. We find that Petitioner has not provided sufficient information for us to find a reasonable likelihood that Gai teaches or suggests dependent claims 5 and 17 at this time. Dependent claim 17 is similar to claim 5, but depends on claim 16 (which in turn depends on independent claim 13), adding “wherein the protocol processor is adapted to update the entries in the database to point to the second access port before receiving the communication traffic from the one or more access switches on the second port.” Id. at claim 17. These claims both require the switch implementing the method for rapid recovery, such as switch 124 in Petitioner’s example discussed above, to update its filtering database before receiving communication traffic from access switches, such as access switches 115 and 116 in Petitioner’s example. Pet. 58. That effectively means that switch 124 must update its database immediately upon transitioning to the new port either before or at the same time it transmits dummy messages to the access switches. So this differs from the analysis for claim 4 because allowing the corresponding entry in the filtering database to time out will not be sufficient to ensure that the entries will be updated before receiving communication traffic from one of the access switches. There is no express disclosure from the portions of Gai cited by Petitioner of immediately updating the database on the switch implementing the method. Pet. 57–58, 94; Ex. 1005, 2:30–41, 5:36–39, 5:54–56, 12:62– 65. Based on the current record, we are also not persuaded by Petitioner’s declarant’s explanation of why Gai allegedly teaches or suggests this limitation. In the section addressing dependent claim 5, Dr. Houh asserts that: are transmitted before any communication traffic is received by the switch. As I discuss in Section VIII.A.5.ii, the filtering database is updated before transmitting the dummy messages. Accordingly, a POSITA would have understood that the database entries would have been updated before receiving any communication traffic from the access switches. Ex. 1003 ¶ 139. However, Section VIII.A.5.ii of Dr. Houh’s declaration relates to dependent claim 4 which does not have any timing requirement, and the citations to Gai there do not describe that the switch first updates its filtering database before sending the dummy message.12 Id. ¶¶ 133–136.

      “Id. Therefore, after a failure and switchover, edge switch 124 transmits dummy traffic to access switch 116 over the second link. Id. Based on the current record, we agree that this example is at least suggested by Gai’s teaching that “the method and apparatus manifests, in part, as a series of novel commands that may be entered at the devices. The devices, moreover, may be classified as either access switches or backbone switches.” Ex. 1005, 6:6–9. Switch 124 is a backbone switch because it interconnects at least access switches 114–116, and, according to Gai, the invention can be implemented on that switch by entering the corresponding commands on it. Id. The rest of the example, whereby ports are switched based on a failure and dummy traffic that is transmitted to the access switches updates their filtering databases, also follows Gai’s teaching. Pet. 39–46; Ex. 1005, 5:35– 6:12. Patent Owner responds to this argument by asserting that “Gai itself never describes backbone switch 124 in such a way,” disputing it could transmit dummy traffic to access switch 116 over the second link. Prelim. Resp. 10–11. Rather, according to Patent Owner, “Gai clearly explains that such an action is in response to a port failure in access switch 114, not in teaching to the preferred embodiment that describes the failure occurring at switch 114, which we do not find warranted in view of the general teaching from Gai discussed above saying the invention can also be implemented on backbone switches.

Petitioner has submitted such a stipulation for all claims in this proceeding, which are all of the claims of the ’215 patent. Ex. 1093; Paper 8 at 1; Paper 9 at 1. Thus, we do not exercise discretion to deny institution under 35 U.S.C. § 314(a).” slip op. at 5

      “In evaluating arguments under Section 325(d), we use a two-part framework, determining, first, “whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments previously were presented to the Office.” Advanced Bionics, LLC v. MED-EL Elektromedizinische Geräte GmbH, IPR2019-01469, Paper 6 at 8 (PTAB Feb. 13, 2020) (precedential). If either condition of the first part of the framework is satisfied, we then determine “whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims.” Id.” slip op. at 6

      “On this record, we are sufficiently persuaded by Petitioner’s argument that a person of ordinary skill in the art would have combined the teachings of Perego and JESD79-2. As Petitioner correctly points out (Pet. 32), Perego discloses using DDR2 memory devices. Ex. 1071, 10:56–59 (“Other memory devices may be implemented on module 400, for example, Double Data Rate 2 (DDR2) DRAM devices and Synchronous DRAM (SDRAM) devices.”). On this record, we find this teaching to use DDR2 sufficiently supports Petitioner’s rationale to combine Perego with JESD79-2, which is the JEDEC DDR2 SDRAM Specification. Ex. 1064, 1 (cover page); see also Prelim. Resp. 44 (parenthetical noting that “JESD79-2 is a specification for individual DDR2 SDRAMs”). As to Patent Owner’s argument that Rambus memories lack a chip select network (Prelim. Resp. 25–26), the reference on which Patent Owner relies discloses that chip select information is still used in the particular Rambus devices described. See Ex. 1069, 11 (“[I]n the Rambus bus organization, all addresses, commands, data, and chip-select information are sent on the same bus lines.”), 12 (“[T]he example system uses a total of nine (9) lines to carry all necessary information, including addresses, commands, chip-select information, and data.”). Thus, on this record, Patent Owner’s focus on the lack of a chip select network, which is not recited in the claims of the ’215 patent, appears misplaced. We address Patent Owner’s more specific arguments below in the discussion of individual claim recitations.” slip op. at 14

      “Claim 21 is method claim and recites similar structure in the preamble. Petitioner cites this claim language in support of its position that a rank can have just one memory device. Pet. 28 (citing Ex. 1001, 37:32–38 (portion of claim reproduced above)). On this record, we determine that the claim language supports Petitioner’s position. Claim 1 recites “at least one first memory integrated circuit in the first rank and at least one second memory integrated circuit in the second rank.” This language is met if there is one memory integrated circuit in each rank because “at least one” includes just one. On this record, we disagree with Patent Owner’s argument that this claim language “do[es] not define the term ‘rank’” but, rather, “provide[s] context that a claimed ‘buffer’ can be, but need not be, coupled to multiple memory devices in the rank.” See Prelim. Resp. 9–10. Claim 1 recites “a buffer coupled between the at least one first memory integrated circuit and the memory bus, and between the at least one second memory integrated circuit and the memory bus,” and it further recites “enabl[ing] communication of the first data burst between the at least one first memory integrated circuit and the memory controller through the buffer” and “enabl[ing] communication of the second data burst between the at least one second memory integrated circuit and the memory controller through the buffer.” If there is only one memory device in each rank, then the buffer will only be connected to the one memory device in each rank. If two memory devices are the “at least one first memory integrated circuit in the first rank” then the buffer would be “coupled between the [two memory devices] and the memory bus.”” slip op. at 10
